The core platform / Core platform (core board / core board, core / core) is a swinging platform that does not have a stable position. In another way, it is also called a “balancing board, since it tilts in absolutely all directions, up to rotation.
Peculiarities
The core platform was invented not by anyone, but by a physiotherapist. He set himself the goal of creating a device for group programs with an inertial (remaining motionless with a balanced, compensated external influence) rotary (rotating) effect. This is how the group training simulator appeared, giving the feeling of an unwinding spring, powerfully acting on the entire system of oblique muscles.
This sports equipment represents two platforms connected to each other by a spring.
The core platform has the ability to regulate the load - for this it is necessary to change the level of spring resistance. Usually there are two of them: for beginners and for professionals.
Core platform
The muscles worked out on this simulator even have the same name. Core muscles. This is a series of muscles (not only the abdomen) responsible for stabilizing the pelvis and spine, as well as, according to some experts, also the shoulder girdle.
The core muscles include, for example, the oblique and transverse abdominal muscles, rectus femoris, gluteus minimus and medius, adductors, hamstrings, coracobrachialis, etc.
Core platform
Possibilities
During core platform exercises, the body moves naturally. In this case, it rotates simultaneously in three planes, therefore many joints and a large number of muscles are being trained, which remain without load when exercising with other simulators.
Exercises on this simulator work not only those muscles to which they are directly directed, but also those that help you keep your body in a given position. After all, striving to maintain balance, you pump deep stabilizing muscles, latissimus muscle back and muscles of the thighs and buttocks, oblique and transverse muscle abdomen, pectoral muscles.
The most important thing is that workouts give you good posture and a toned abs.
Classes on the core platform are considered good prevention of osteochondrosis and hernias.
The core platform can be used for both cardio and strength training for recovery. muscle imbalance improving sports performance. Therefore, such training is used and in order to prepare for active classes sports, such as surfing, snowboarding, alpine skiing, rollerblading.
In fitness rooms, exercises with a core platform are often combined with exercises with a medball, with dumbbells, shock absorbers, and a bodybar, which makes the workout more effective and varied.
For an hour of core training you can get rid of extra 300-350 kilocalories and increase the energy consumption of the body by 30-40%.
Due to the need to constantly maintain balance, this projectile helps to develop agility, endurance, strength of speed and coherence of movements, as well as improve the functioning of the vestibular apparatus. situations.
Security
Core training is recommended for people of all fitness levels and ages. Although some instructors are in no hurry to include them in the beginner's program. Because such a rather high load on unprepared muscles can lead to injuries.
Despite the instability of the machine, it can be completely safe to train with it. It is enough to observe correct technique exercise and take your time. This applies to those who are afraid of falling off the machine.
Exercises
The core platform does not apply to equipment used exclusively in fitness rooms. It is quite worthy of becoming a home simulator, thanks to its size and variety of exercises, from which it is quite possible to choose less acrobatic, and therefore safe for independent execution.
Trying core training in the gym under the guidance of an experienced instructor will not be superfluous, even if you already have a core platform at home. Firstly, at the very beginning of the lesson, you can see several good exercise for home and understand how to behave with the simulator so as not to fall off it. Secondly, when you are already comfortable with the apparatus and get bored of the usual movements, you can get the so-called "advanced training" from the instructor.
Core platform
So, here are some basic exercises for self-core training.
Leg exercises
- Stand on the core platform in the central area. Move your center of gravity to one leg and find your balance. Move the other leg to the side and touch the floor while simultaneously bending the thigh and knee of the supporting leg (standing on the bark). To do this, transfer balance to the heel, the lower leg should remain at a right angle to the core platform. At the same time, keep your back straight, bring your shoulder blades together. After that, smoothly return to the starting position.
Repeat the exercise with the other leg. Thus, you should get lunges to the sides ( right leg on the bark - on the floor - on the bark, then left leg on the bark - on the floor - on the bark).
- Back lunges are done in the same way.
Exercises for the press
- Lie with your back on the core platform (lower torso on the floor). Bend your knees. Lift your pelvis up. Catch your balance. And repeat the exercise.
- Lie on the machine with your pelvis in the center. Raise your torso and at the same time pull your knees towards your chest. Find your balance. Then return to the starting position.
Hand exercise
Take a push-up position (with support on toes or knees - depending on the level of training), grasping the edges of the core platform with your hands. Catch your balance. And, without losing it, perform the rotation of the core platform using the muscles of the arms.
Lateral muscle exercise
Stand with your feet on the edges of the core platform. Catch your balance. And, while continuing to hold it, try to rotate the simulator exclusively with the muscles of the body.
A balance trainer is an unstable sports equipment used for balance training.
Exercising on a balancing machine is very good at strengthening the stabilizing muscles, which are poorly involved in normal training. Even performing simple movements, you have to maintain balance, thereby forcing the small muscles to work.
Balance exercises develop flexibility and improve posture. Balance trainings effectively strengthen the musculoskeletal system, while the load on the joints is minimal. When exercising on balancing apparatus, almost all muscles are actively involved, which contributes to a harmonious physical development body.
Balance training involves proprioceptive receptors located in muscles, tendons, and ligaments. They are responsible for a sense of balance in our body and respond to changes in body position. Thanks to the training of these receptors, a person feels his body in space better, and his coordination develops well.
How to train on a balance trainer
Exercising on an unstable machine is not that difficult. The rule of thumb is to start with light, low-intensity exercise to get a feel for balance training. It is not recommended for beginners to make sudden movements, to engage in fast pace- this can lead to injury.First you need to learn how to get on and off the shell, walking straight. Then you need to master the steps to the sides and back. As you gain confidence and balance easier, you can add any exercises that you do in a regular workout. Simple and familiar, on the balancing platform they turn into something new, interesting and not always easy to do.
With the help of a balancing machine, you can diversify any cardio and power training, improve their efficiency.
Types of balancing simulators
The most popular types of unstable sports equipment include: barefoot, hemisphere, disc, pillow, step and core platform.#1. Bosu ( Bosu: Both Side Use)
The Bosu is like a half fitball with a solid base. The peculiarity of the simulator is that you can perform exercises on it from both sides. By installing bosu with the dome up, you can use it in the following options:
as a step, doing typical step aerobics exercises for the muscles of the legs and buttocks;
instead of a bench - to strengthen the muscles of the back, chest and arms ( presses, raising arms using dumbbells or weights);
as a support for working out the muscles of the press and back ( twisting, hyperextension).
In the inverted state, the simulator allows you to do push-ups and planks, train your biceps, triceps, shoulders, as well as your back and abs. By adjusting the pressure of the projectile, you can vary the difficulty of the exercises performed.
# 2. Balancing massage pillow
It is a rubber disc partially filled with air. Compact and lightweight, it takes up little space and is perfect for home workouts. The relief surface improves blood microcirculation in tissues, promotes general relaxation. Exercises on a balancing cushion are recommended for preventing flat feet, strengthening joints and ligaments. Due to its low height, the trainer is safe and suitable for people of all ages, it is ideal for beginners in balance training.
Multiple pillows can be used during exercise. For example, push-ups and squats are more comfortable on two apparatus located at a suitable distance. The elasticity of the pillow changes depending on how much it is inflated.
# 3. Balancing hemisphere
The simulator can have different diameters ( 14-33 cm), its base has a strong adhesion to the floor. It is used to train balance and improve coordination. The embossed or spiked surface perfectly massages the feet and palms, improves blood circulation, and serves to prevent flat feet. You can walk or jump on them, use them as support for your arms or legs, for example, when doing push-ups, lunges, squats.
#4. Balancing disc
The ability to adjust stability makes this simulator universal, both beginners and trained athletes can train on it. For the first sessions, you should think about an additional point of support: it can be a chair or a bodybar. You can also ask someone from your friends or family to insure you at first.
#5. Unstable core platform ( Core)
The simulator allows you to perform cardio and strength training, effectively trains all the muscles of the body. Regular exercises on the core platform increase athletic performance: strength, endurance and speed. Therefore, it is often used in extreme sports ( alpine skiing, snowboarding, surfing) to train athletes in the off-season.
# 6. Unstable step platform
Unlike the usual step, this simulator has an aero base, due to which the effect of instability arises. You can train on such a platform from both sides, which allows you to perform a large variety of exercises.
In addition to the popular balance trainers listed above, there are types such as:
balancing track for practicing various modes of movement;
balls for jumping and keeping balance;
balancing stepper.
The unstable core platform is a suitable option for home workouts, optimizes workouts and increases productivity, enhances the effect of exercises on the figure.
The safety of the Reebok exercise machine makes the core platform child-friendly. The simulator comprehensively works out the muscles of the body and, in terms of efficiency, competes with training in specialized fitness rooms, where classes are conducted under the guidance of a professional instructor.
Reebok approached the platform manufacturing responsibly, used modern development technologies sports equipment, proposed a simulator that will become the basis for a dozen types of activities.
The Reebok core board has a serious list of advantages:
- The board functions in two "modes" - as a balancing board and as a static step trainer, recognized as a classic in the world of fitness;
- The choice of the training mode occurs through a switch, the platform changes static to balancing;
- Instability of the structure simultaneously with muscle training develops a sense of balance;
- The choice of classes consists of classical aerobics, selected types, Pilates, strength training, stretching and other types of exercise;
- Reebok's well-thought-out core platform features a dense rubber coating that prevents feet from slipping in sneakers or bare feet, calves, arms involved in a particular exercise;
- Transportation is provided - using a special handle;
- Reebok has given special attention to striking design in combination with items for rest and recovery after training.
How to use
Reebok board acts as a balancing platform, tilts in all directions under different angles, with the correct weight distribution rotates. The lack of a stable position of the platform allows you to achieve additional load during training.
Before starting training, the degree of load on the body is regulated. Then they try light exercises for torso rotation, for maintaining balance, which help to feel the platform and get used to its movement.
When practicing yoga or static fitness that does not require mastering balance, the static platform mode is used without additional training. It is better for beginners to start with static types of training, and then move on to the development of the vestibular apparatus.
At first, the basis that maintains balance will be a vertical support or any handrail, which is convenient to grab when performing the exercise. Advanced users will then be able to make it harder with the ball, which, by taking up the arms, leads to a loss of balance. Now the balance will have to be kept by muscle tension.
Who suits
A movable board is used for various activities, but it is a necessary trainer for:
- Lovers of active fitness or aerobics with incendiary music;
- Basketball and volleyball players, as well as other participants in sports games;
- People with back problems, which need to be developed with constant stress;
- Dancers, especially those who go in for sports dancing;
- People with poor motor coordination;
- Light exercises are suitable for children who need to develop balance and coordination.
Exercise options
For an easy warm-up on the platform, simple exercises are performed:
- Lunges: one leg stands on the platform, resting on the toe, the other on the floor across the entire foot. From starting position it is necessary that the knees bend at right angles. Repeat the exercise on each leg 15-20 times;
- Back muscle training: they lie on a static platform with their stomachs, rest their toes on the floor and raise the body 20-25 times;
- Abs workout: from a prone position, they turn over onto their back, under the lower back there is a platform, the heels rest on the floor. In this position 20 times, without helping hands;
- Bridge: from a supine position, take an emphasis with your hands and arching your back to stand in a bridge. The presence of a platform makes the exercise easier, but does not reduce its effectiveness;
- Twisting: in a static position of the platform, keep balance in a prone position with your stomach on the board with a raised body and legs torn off the floor. Turning around right hand touch the opposite leg, then the left. Repeat the exercise 20 times;
- Push-ups and jumps: the dynamic component of charging is performed according to the standard scheme (jump, squat, support in a push-up position and jump again).
Complex training for the muscles of the whole body on the core platform was developed by a physiotherapist, which determines the positive effect of training.
Through training, muscles are strengthened, disappears excess weight, develops balance and flexibility. The options for using the rotating platform are limited by your only imagination.
Your feedback on the article:
The first processors under the Intel Core i7 brand appeared nine years ago, but the LGA1366 platform did not pretend to be massively distributed outside the server segment. Actually, all "consumer" processors for it fell into the price range from ≈ $ 300 to full-weight "stukebuck", so there is nothing surprising in this. However, modern i7s also live in it, so they are devices of limited demand: for the most demanding buyers (the appearance of the Core i9 this year has slightly changed the disposition, but just that very little). And already the first models of the family received the formula "four cores - eight threads - 8 MiB of the third level cache".
It was later inherited by models for the mass-market LGA1156. Later it migrated unchanged to LGA1155. Even later, it was "noted" in LGA1150 and even LGA1151, although many users initially expected the appearance of six-core processor models from the latter. But this did not happen in the first version of the platform - the corresponding Core i7 and i5 appeared only this year within the framework of the "eighth" generation, with the "sixth" and "seventh" incompatible. In the opinion of some of our readers (which we partially share) - a little late: they could have done it earlier. However, the claim “good, but not enough” applies not only to processor performance, but in general to any evolutionary changes in any market. The reason for this lies not in the technical, but in the psychological plane, which goes far beyond the sphere of interests of our site. Here we can arrange testing of computer systems of different generations to determine their performance and power consumption (even if, at least, on a limited sample of tasks). What we will do today.

Our parade is opened by the three oldest processors - one for LGA1156 and two for LGA1155. Note that the first two models are unique in their own way. For example, the Core i7-880 (appeared in 2010 - in the second wave of devices for this platform) was the most expensive processor among all the participants in today's test: its recommended price was $ 562. In the future, not a single desktop quad-core Core i7 cost so much. And the quad-core processors of the Sandy Bridge family (as in the previous case, we have a representative of the second wave here, not the "starting" i7-2600K) are the only models for LGA115x that use solder as a thermal interface. In principle, no one noticed its implementation then, as well as the earlier transitions from solder to paste and vice versa: later, in narrow, but noisy circles, they began to endow this thermal interface with truly magical properties. Somewhere starting with the Core i7-3770K just (mid-2012), after which the noise did not subside.

The one we will miss a little today is the original Haswell in the form of the i7-4770K. As a result, we skip 2013 and go straight to 2014: formally 4790K is already Haswell Refresh. Some were already waiting for Broadwell, but the company released processors of this family exclusively to the tablet and laptop market: where they were most in demand. And with the desktop, the plans changed several times, but in 2015 a couple of processors (plus three Xeons) appeared on the market. Very specific: like Haswell and Haswell Refresh, they were installed in the LGA1150 socket, but they were compatible only with a couple of chipsets of 2014, and most importantly, they turned out to be the only "socket" models with a four-level cache memory. Formally - for the needs of the graphics core, although in practice all programs can use L4. There were similar processors both earlier and later - but only in BGA-execution (that is, they were soldered directly to the motherboard). These are also unique in their own way. Enthusiasts, of course, were not inspired because of the low clock speeds and limited "overclocking", but we will check: how this "side escape" relates to the main line in modern software.

And the most recent triple of processors, formally using the same LGA1151 socket, but in two incompatible versions. However, we wrote about the difficult path of six-core mass-line processors to the market quite recently: when they were tested for the first time. So we will not repeat ourselves. We only note that we tested the i7-8700K again: using not a preliminary, but a “release” copy, and even installing it on an already “normal” motherboard with debugged firmware. The results did not change significantly, but in several programs they became somewhat more adequate.

With whom to compare the results? It seems to us that it is imperative to take a pair of the fastest modern dual- and quad-core processors of the Core i3 and Core i5 lines, since they have already been tested, and it is interesting to see which of the oldies they will catch up with and where (and whether they will catch up). In addition, we managed to get a completely new six-core Core i5-8400, so we took the opportunity to test it too.

You can't do without AMD processors, and there's no need to. Including the "historical" FX-8350, which is the same age as the Core i7-3770K. Fans of this line have always argued that it is not only cheaper, but generally better - just very few people know how to cook it... But if you use " the right programs", Then immediately overtake everyone. We are from this year just at the request of workers We reworked the testing methodology towards "severe multithreading", so there is a reason to test this hypothesis - all the same, testing is historical. And modern models will require at least two. The Ryzen 5 1500X would be very suitable for us, very similar to the old Core i7, but it has not been tested. The Ryzen 5 1400 is formally also suitable ... but in fact, this model (and modern Ryzen 3), along with the halving of the cache memory, also "suffered" the connections between the CCX. Therefore, we also had to take the Ryzen 5 1600, where this problem does not exist - as a result of which it often overtakes 1400 more than one and a half times. And a couple of six-core Intel processors are also present in today's testing. Others are clearly too slow to compare with this inexpensive processor, well, okay - let it dominate.
Testing methodology
Methodology. Here we briefly recall that it is based on the following four whales:
- Methodology for measuring power consumption when testing processors
- Methodology for monitoring power, temperature and processor load during testing
- Methodology for measuring performance in games sample of 2017
Detailed results of all tests are available as a complete table with results (in Microsoft Excel 97-2003 format). Directly in the articles, we use already processed data. This is especially true for application tests, where everything is normalized relative to the reference system (AMD FX-8350 with 16 GB of memory, a GeForce GTX 1070 video card and a Corsair Force LE 960 GB SSD) and is grouped according to the scope of the computer.
iXBT Application Benchmark 2017
Basically, the claims of AMD fans that the FX were not so bad in "severe multithreading", if we consider only the performance, are justified: as you can see, the 8350 could in principle compete on equal terms with the Core i7 of the same release year. However, here it looks good against the background of the younger Ryzen, but between these two families practically nothing was produced by the company for this market segment. Intel has such a uniform lineup, which has made it possible to double the performance within the framework of the “quad-core” concept. Although the cores are of great importance here - the best dual-core in 2017 still did not catch up with the quad-core Core of the "previous" generation (recall that it is still officially called so in the materials of the company, clearly separating from the numbered ones starting from the second). And six-core models are good - and that's all. So, Intel's accusations that the company delayed their entry to the market too long can be considered to some extent fair.
All the difference from the previous group is that the code is not so primitive here, so, apart from cores, threads and gigahertz, the architectural features of the processors running it are also important. Although the overall result for Intel products is quite comparable: the difference between 880 and 7700K is still twofold, the i5-8400 is still inferior only to the latter, the i3-7350K still hasn't caught up with anyone. And this happened in the same seven years. We can assume that there are eight - after all, LGA1156 entered the market in the fall of 2009, and the Core i7-880 differed from the 860 and 870 that appeared in the first wave only in frequencies, and even then a little.
One has only to "weaken" the utilization of multithreading a little, so the position of newer processors immediately improves - albeit weaker in quantity. However, the traditional "two ends", all other (relatively) equal, comparison of the "previous" and "seventh" generations of Core gives us. Although it is easy to see that the "second" and ... "eighth" are drawn to the "revolutionary" to the maximum extent. But this is more than understandable: the latter increased the number of cores, and in the "second" the microarchitecture and technical process changed radically, and at the same time.
As we already know, Adobe Photoshop is a bit "odd" (bad news - the problem has not been fixed in the latest version of the package; very bad news - now it will be relevant for the new Core i3), so we don't consider processors without HT. But our main characters have support for this technology, so no one bothers them all to work normally. As a result, in general, the state of affairs is similar to other groups, but there is a nuance: the fastest processor for the LGA1150 turned out to be the i7-4790K, which does not have a high frequency, but the i7-5775C. Well - in some places intensive methods of increasing productivity are very effective. It is a pity that not always: it is easier to “work” with frequency. And cheaper: you don't need an additional eDRAM crystal, which also needs to be somehow placed on the same substrate with the "main" one.
The number of cores as a "driver" for increasing performance is also suitable - even more than the frequency. Although in our first testing, the Core i7-8700K looked worse, but this was due to the results of the same Adobe Photoshop: they turned out to be almost the same as for the i7-7700K. Switching to a "release" processor and motherboard solved the problem in this case: the performance turned out to be similar to other six-core Intel processors. With a corresponding improvement overall result in a group. The behavior of other programs has not changed - they previously had a positive attitude towards increasing the number of supported computing threads while maintaining a similar level of such frequency.
Moreover, sometimes it is only she who "decides", and the number of computation threads. Basically, of course, there are certain nuances here, but “ there is no reception against scrap". The entire revolutionary Ryzen architecture, for example, allowed the 1400 to only deliver performance on par with the FX-8350 or Core i7-3770K that hit the market in 2012. Considering that it has a frequency lower than both, and in general this is a special budget model, in fact, using only half of a semiconductor crystal, it is not so bad. But it does not cause reverence. Especially against the background of another (and also inexpensive) representative of the Ryzen 5 line, which easily and noticeably overtook any quad-core Core i7 of any production year :)
Although we abandoned the single-threaded decompression test, this program still cannot be considered too "greedy" for cores and their frequencies. It is clear why - the performance of the memory system is very important here, so the Core i7-5775C was able to overtake only the i7-8700K, and even then by less than 10%. It is a pity that there are no products yet, where L4 is combined with six cores and memory with a high memory bandwidth: such a processor "without bottlenecks" in such tasks could show a miracle... In theory, at least - it is obvious that we will not see anything like this in desktop computers in the near future for sure.
It is characteristic that this branch of the "backbone" of desktop processors demonstrates (still!) High results in this group of programs as well. However, what unites them is mainly the purpose, and not the optimization methods chosen by the programmers. But the latter are not ignored either - in contrast to some more "primitive" tasks, such as video encoding.
What do we end up with? The effect of "evolutionary development" has somewhat diminished: Core i7-7700K outperforms i7-880 by less than two times, and its superiority over i7-2700K is only one and a half times. On the whole - not bad: it was achieved by intensive means in comparable "quantitative" conditions, that is, it can be applied to almost any software. However, in relation to the interests of the most demanding users, it is not enough. Especially if we compare the gains at each annual step, adding another Core i7-4770K (which is why we regretted above that this processor was not found).
At the same time, the company has had the opportunity to dramatically increase performance at least in multi-threaded software (and there have been many such programs among resource-intensive programs for a long time). And it was also implemented - but within the framework of completely different platforms with their own characteristics. No wonder many have been waiting for six-core models for LGA115x since 2014 ... But many did not expect any breakthroughs from AMD in those years - all the more impressive were the first Ryzen tests. Not surprisingly - as we can see, even the inexpensive Ryzen 5 1600 can compete in performance with the Core i7-7700K, which was the fastest processor for the LGA1151 just a couple of months ago. Now a similar level of performance is quite available for Core i5, but it would be better if it happened earlier :) In any case, there would be fewer reasons for complaints.
Energy consumption and energy efficiency
However, this diagram once again demonstrates why the performance of mass central processors in the second decade of the 21st century grew at a much slower pace than in the first: in this case, all development took place against the background of “non-increase” in energy consumption. Even reductions, if possible. It was possible to reduce it by architectural or some other methods - users of mobile and compact systems (which have long been sold much more than "typical desktop") will be satisfied. Yes, and on the desktop market, a small step forward, since you can tweak the frequencies a little more, which was done in the Core i7-4790K at one time, and then was fixed in the "regular" Core i7, and even in the Core i5.
This is especially evident from the assessment of the power consumption of the processors themselves (unfortunately, for LGA1155, measure it separately from the platform by simple means impossible). At the same time, it becomes clear why the company does not need to somehow change the requirements for cooling processors within the LGA115x line. Also, why more and more products in the (formally) desktop assortment are starting to fit into traditional laptop processors thermal packs: this happens without any effort. In principle, it would be possible to install all quad-core processors under LGA1151 TDP = 65 W and not suffer :) Just for the so-called. For overclocking processors, the company considers it necessary to tighten the requirements for the cooling system, since there is a small (but also non-zero) probability that the buyer of a computer with such will overclock it and use all sorts of "stability tests". And mass products do not cause such fears, and they are initially more economical. Even six-core ones, although the power consumption of the older i7-8700K has grown - but only to the level of processors for LGA1150. In normal mode, of course - during overclocking, you can inadvertently return to 2010 :)
But, at the same time, modern economical processors are not necessarily slow - three to five years ago, the performance of "energy efficient" models against the background of the top in the lineup often left much to be desired, since they had to reduce the frequency too much, or even reduce the number of cores. Therefore, in general, "energy efficiency" has increased much faster than pure performance: here, when comparing the Core i7-7700K and i7-880, not twice, but all two and a half. However ... the first "big leap" and immediately one and a half times fell on the introduction of LGA1155, so it is not surprising that complaints about the further evolution of the platform were heard from this direction as well.
iXBT Game Benchmark 2017
The most interesting are, of course, the results of the oldest processors, such as the Core i7-880 and i7-2700K. Unfortunately, nothing good happened with the first of them: apparently, none of the GPU manufacturers seriously dealt with the issues of compatibility of new video cards with the platform of the end of the last decade. And it's understandable why: many LGA1156 skipped altogether, or have already managed to migrate from it to other solutions for so many years. And with the Core i7-2700K, there is another problem: its performance (recall - in normal mode) is still often enough to work at the level of the new Core i7. In general, there is such an unkillable legend: which (together with the older Core i5 for LGA1155), at first, a good game processor was made by high single-threaded performance (in those years, Intel strongly "pinched" Core i3 and Pentium in frequency), and then they started more or less effectively all eight supported computation threads are utilized. Although the same level of performance in games is often achieved by more "simple" solutions for new platforms, but sometimes there is a feeling that this is connected not only and not so much with performance "in its pure form". Therefore, for those who are to some extent interested in the results in games, we recommend that you familiarize yourself with them using the full table, and here we will give only a couple of the most interesting and illustrative diagrams.
Take Far Cry Primal, for example. We immediately discard the results of Core i7-880: the incorrect operation of the video card on the GTX 1070 with this platform is obvious. Perhaps, by the way, the same is applicable to the LGA1155, although in general the frame rate cannot be called low here: in practice it is enough. But clearly lower than it could have been. And LGA1151 also somehow does not shine and LGA1150 looks like the best platform. Now we recall that a modified version of the Dunia Engine 2 (which is used here) was developed between 2013 and 2014, so they could just reoptimize... An indirect confirmation of this is the low (relatively expected) frame rate on Ryzen 5: there is a feeling that there should be more and that's it.
But games on the EGO 4.0 engine began to appear in 2015 - and here we already do not see such artifacts. Except for the Core i7-880, which once again amused us with its "brakes", but it correlates well with other games as well. And the best looks are not just multi-core processors, but those released since 2015, that is, the LGA1151 and AM4 platforms. The exact opposite of the previous case, although in general both games were released in 2016. And both within the same processor family always "vote" for the model in which there are more computing cores. But within one- different (all the more, significantly different architecturally) with their help must be compared very carefully. If you want to compare, of course: in general, in both (and not only in them) on a system with a five-year-old processor and a "good" video card, you can play with much more comfort than with any processor, but on a budget video card for $ 200 In general, the requirements for the processors of games are growing or not, and the gaming computer needs to be assembled “from a video card”. However, it would be strange if something would change in this industry - especially considering that the performance of video cards over the past eight years has not doubled or even tripled over the past eight years;)
Total
Actually, all we wanted to do was compare several processors from different years at once when working with modern software. Moreover, some characteristics of older Core i7 models have practically not changed during this time, especially if we take the interval from the winter of 2011 to the same period in 2017. But productivity grew at the same time - slowly, but slightly more than the often discussed "5% per year". And taking into account the fact that every year a normal user does not buy computers, but usually focuses on 3-5 years - during such a period, "accumulated" in performance, and in efficiency, and in the functionality of the platform. But could have been better... At the same time, some " weak spots»: For example, the increase in clock frequency in 2014 did not allow achieving significantly higher performance neither in 2015, nor even at the beginning of 2017. We managed to break away from LGA1155 noticeably (as the software was optimized for processors starting with Haswell, the results were more modest at the start), that's all. And then (all of a sudden) + 30% productivity, which hasn't happened for a long time. In general, from a historical point of view, a smoother implementation of this process would look better. But what happened was already there.

There are people who need to pay money to motivate themselves to exercise regularly. And there are those who prefer to improve themselves without leaving home. This also has its undeniable advantages. You can study at any convenient time, without wasting time on the road and money on a subscription, and the right simulator always available, there is no need to take a queue for it in advance. If you belong to the second type, then you should always be aware of all the new house fit products in order to replenish your collection of home exercise equipment.
One of these fitness gadgets is a core board or core platform - special device, a recent development of physiotherapists at Reebok University (London), which has no stable position. If you compare it roughly, you can draw an analogy with a fitball - both devices are a balancing unstable surface. The name of this platform comes from the English word core, meaning core, core. The simulator consists of two oval boards, on average, 88 cm long, 15 cm high and 67 wide, on a special stand that does not allow the board to be fixed, but is capable of turning and changing the angle of inclination in any position. This feature allows you to work out all oblique muscles of the body.
The platform is completely safe, as its cover is made of special rubber, which provides maximum grip of the feet with the board. Durable rubber clips secure the platform firmly to any surface, even marble bathroom floors. Also, the core board has 2 levels of resistance, which contribute to a decrease or increase in its stability. After all, for beginners, complete or very tall people it is not so easy to start balancing easily on a board that is too mobile.
What muscles we train

Working with a core platform is kind of like skateboarding, snowboarding or windsurfing. You have to constantly balance, change body position and strain alternately different groups muscles so as not to lose balance and fall to the floor (asphalt, into the ocean). Only you do not need to catch a wave in Sydney or rip your knees on the asphalt, trying to maneuver between passers-by and cars. All the same will be provided to you at home by the core platform. Namely: general strengthening muscle body, working out small muscle groups and deep muscle layers, excellent muscle pumping abdominal and the small pelvis, the full use of all muscle groups that support our legs in shape.
In addition, the core platform will help you create excellent posture, develop a sense of balance and improve coordination of movements. Exercising on such a simulator, you simultaneously get two in one, combining strength and aerobic exercise In addition, training on the core platform is an excellent prevention of osteochondrosis and the development of intervertebral hernias and protrusions, since they strengthen absolutely all the muscles that support the spine and back in correct position... Training on such a platform is considered very intense, since we expend a huge amount of calories to maintain balance.
Additional gadgets
If your level physical fitness high enough, in winter you regularly go skiing and snowboarding, and in summer - surfing and skateboarding, it makes sense to purchase special gadgets that come with it along with the core platform. These are resistance bands equipped with three levels of resistance for people with different levels physical training (along the edges of the platform there are special holes for their fastening), which allow performing strength exercises in parallel with aerobic load. And also pampas - aerobic barbells, bodybars - gymnastic sticks, medical balls and special core-mats.
Where to study
Group classes on the core platform are offered by the Sport-Studio fitness club. You can buy the platform for home workouts in the Reebok brand stores - the company that owns the copyright for the invention of this gadget, as well as in online stores, for example.
