Is the A15 chip of the iPhone 13 a little slower in CPU progress?
'iPhone 13' series, the new iPhone for 2021. Regarding the SoC 'A15 Bionic ', which is one of the highlights of the iPhone 13 series, it has been pointed out that 'the outflow of human resources has forced us to put more weight on the GPU than on the CPU.'

On September 15, 2021, Apple announced the new 2021 iPhone 'iPhone 13' series at a new product launch event. The iPhone 13 series features a higher-performance main camera and a ceramic shield that is stronger than any smartphone cover glass, and you can check other details in the following articles.

Among the announcements about the iPhone 13 series, the big feature was the new SoC 'A15 Bionic'. The explanation about A15 Bionic was allocated longer than other items in the recital, and on the official page of iPhone 13 released after that, 'A15 Bionic is much faster and better than other chips. In order to deliver better performance and better power efficiency, everything in the iPhone 13 lineup works more fluidly than ever before. '
The suspicion that 'Apple intentionally blurred the concrete performance' has been talked about about this A15 Bionic. It was customary for Apple to compare new devices with past models at the recital, but for this iPhone 13, 'up to 50% faster than major other companies'products', an abstract 'other company's product' as a comparison target I used the expression.
The part that can be inferred from the specific performance is the expression 'The CPU performance of the A15 Bionic is 40% faster than the A12 Bionic' used during the announcement of the iPad mini. It seems that 40% speed has achieved a dramatic evolution, but considering the benchmark results, it has achieved about 40% speedup compared to A12 Bionic at the time of A14 Bionic, so 'A15 Bionic' And A14 Bionic are equivalent in terms of CPU? '
At the stage when this suspicion surfaced, the media reported that 'Isn't it the case that three semiconductor division executives left Apple in 2019?' Gerrard Williams and others who have served as development leaders of Apple A series such as A12 Bionic left Apple in 2019 and established a company called 'NUVIA'. NUVIA was acquired by Qualcomm in January 2021 for about 145 billion yen, contributing to the improvement of Qualcomm's CPU design capabilities.

In addition, since the suspicion about the CPU performance of the A15 Bionic, a benchmark score that seems to be the iPhone 13 series has been found on the benchmark giant GeekBench, and if this score is definitely that of the iPhone 13 series, the A15 Bionic is compared to the A14 Bionic. The single core score has increased by about 10%, and the multi-score has increased by about 20%.
You can see the score of iPhone 13 series existing on GeekBench from the following. Please note that the registered name is 'iPhone 14' as of September 16th, probably because it is in the pre-launch stage.

When comparing single core scores, A13 Bionic is 18% higher than A12 Bionic and A14 Bionic is 20% higher than A13 Bionic, so the current information gives the impression that the CPU performance improvement rate has slowed down a little. is.
