Vratislav Holub Last month, a new generation of Apple phones was unveiled, labeled iPhone 13. Apple he specifically served us four models, which, although proud of the same body as last year's series, bring interesting news in terms of display, cameras and video. Of course, the Cupertino giant also bet on a new chip Apple A15 Bionic, which is said to be 50% more powerful than the competition. However, this is a somewhat vague designation that does not reveal much about the capabilities of the new phones.

That's exactly why it's on the edge of the chip Apple A15 Bionic looked at the portal AnandTech. At the outset, we can mention that according to their findings, the chip is not 50% better than the competition, but by 62%. At the same time, it uses significantly more energy-demanding cores, but even so, the chip is generally relatively economical and works well with the available resources. The A15 chip is likely based on the improved 5nm+ manufacturing process that TSMC, a leading chip maker for Apple, refers to as N5P. In addition, the system cache also received improvements, which even doubled to 32 MB. After all, this is the key to economical performance. Similarly, it improved the L2 cache for two powerful cores (out of a total of six, the other four are economical). This was increased by 50% from the original 8 MB to 12 MB. Although at first glance these are negligible values, it should be noted that thanks to this, the A15 chip, i.e. its two powerful cores, reach the same level as the M2 chip in the case of L1 cache.

To make matters worse, it is also 17% more economical (at maximum load) compared to its predecessor in the form of a chip Apple A14 Bionic. Even so, it has its Achilles' heel. In any case, this is not a problem of the chip itself, but of the heat dissipation system, due to which phones can encounter thermal throttlingThis system is one of the worst in iPhones – heat does not spread well through the body of the phone and is therefore difficult to dissipate. Despite this, it is iPhone 13 (Pro) significantly ahead of its competition in terms of performance.
How time has passed and where the performance will move
It's no secret that mobile chips are in development Apple in short, a little ahead. After all, this is also demonstrated by the graph from Creative strategies, which takes into account the results of iPhones in benchmark tests, or rather in single-core tests. The graph then also takes into account the year-on-year increase in performance. This is most visible between the A8 and A9 chips, i.e. between iPhonem 6 a iPhonem 6S, when Apple was able to increase the performance by a rocket. It is also interesting to look at changing the phone once every three to four years, which, by the way, is the most common model for switching to newer iPhones. In this case, on average, you can count on doubling the performance.
At the same time, there is room to think about where performance will move in the coming years. There have also been opinions on the Internet that Apple in the case of a chip Apple The A15 Bionic has hit the imaginary limit of its current capabilities. However, the current analysis from AnandTech does not entirely indicate this - in the end, the Cupertino giant increased the performance a little more than it initially presented, while also managing to work on energy saving.
