Are you announcing Apple's new product? Became

 

The person who notices this is a maniac.

Among those who were watching the explanation of the latest processor " A15 Bionic " which drives the iPhone 13, Pro, and iPad mini at the Apple autumn announcement event, "Always boasting an evolution compared to the old model. This year, I can't find any comparison figures from the previous year! Well, the CPU performance hasn't changed much from last year's A14 ... ? "

Certainly, if you look at last year's commentary ...

Both CPU and GPU are "50% faster than any other smartphone chip", and in the case of M1 before that, "CPU is up to 3.5 times faster, GPU is up to 6 times faster, machine learning is up to 15 times faster" "That's the number compared to the previous Intel chip. If that impression is strong, you will probably feel, "Why did you suddenly become a competitive comparison !?"

Continued brain outflow

At Apple, the CPU chief architect transferred 100 engineers to NUVIA (a chip design company of Qualcomm's subsidiary) in 2019, and excellent human resources are leaking to RISC V's startup RIVOS this month as well. In a hurry, we are recruiting RISC V programmers, and it is in the news. It seems that there are some behind-the-scenes circumstances in the field that people are worried about the future of Apple's CPU development.

If you calculate the CPU performance difference with the numbers of the iPad mini ...

The new iPhone A15 uses the same 5nm process as the A14, with a CPU of 6 cores and a GPU of 4 cores, just like the A14. The new iPad mini has 5 GPU cores. Although it is not possible to make a general comparison, these numbers are given in the announcement.

"The new iPad mini (A15) has a CPU 40% faster and a GPU 80% faster than the old iPad mini (A12)."

After that, if you know the difference between A12 and A14, you can roughly understand the difference between A14 and A15 by subtraction. About this, when the A14-equipped iPad Air was announced last year, the number compared to the A12 old iPad Air was given.

"The iPad Air (A14) has a 40% improvement in CPU and 30% improvement in GPU compared to the old iPad Air (A12)."

In other words, as Semi Analysis wrote, the CPU performance of both the new iPad mini (A15) and iPad Air (A14) is 40% higher than the old A12 product. By subtracting, the change in CPU from A14 to A15 is zero ...

Initial bench results and harsh reality

As soon as this story spread, the results of the initial benchmark that "GPU performance improved by 55% on iPhone 13 Pro" came out to counteract it, but Semi Analysis also incorporated more detailed figures. Update the article. What emerges from it is an unexpectedly harsh reality.

The improvement in GPU performance is remarkable, but "the overall performance has only evolved slightly for the increase in transistors from 11.8 billion to 15 billion, " he said. "Next year's A16 will be an N4 process instead of an N3." If that happens, it will slow down further. "," The development of next-generation CPU cores may be delayed next year due to the outflow of CPU engineers. "

By the way, Nuvia is a start-up company acquired by Qualcomm for $ 1.4 billion after its founding in 2019. Apple has pulled out talented people from Intel and became the CPU champion, but now that the opposite phenomenon is happening, Silicon Valley is always repeating this ... If you are interested, please follow the link below.
