At the time, it was predicted that the A16 chip would be the first Apple chip to support the new v9 instruction set. However, Apple supports ARM v8.6 with many of its own extensions. The iPhone 15, which will be released this year, is expected to support ARM v9 with an increase in transistors.
What are the benefits of the ARM v9 instruction Phone Number List set and architecture? Apple designs its own CPU cores, and the performance benefits promised by the v9 architecture have already been realized in Apple designs and ARM extensions. In fact, the Snapdragon 8 1st generation was the first high-end smartphone CPU equipped with ARM's Cortex-X2 core supporting ARM v9, but the performance of the Apple A15 chip surpassed the Snapdragon 8 1st generation.
There are many claims that ARM v9 improves performance by 30% over ARM v8. However, this is an argument based on ARM's own core design and does not take custom extensions into account. Apple is on a completely different playing field. The CPU performance of the A17 probably won't improve by 30%.
It is almost certain that the speed of the CPU core used in the A17 will be faster. But it's not just because of ARM v9. CPU core performance is affected by numerous factors, including instruction set, branch prediction, instruction decoding, execution units, cache structure and size, and clock speed.
When looking at the general number of cores, there is not much reason to go beyond the configuration of 4 efficiency cores and 2 performance cores that has been continued since the A11 Bionic. This configuration will probably improve performance by about 15%.
Considering the extent of performance improvement over the past few years, we predicted the Geekbench score of the A17 chip. ⓒ Foundry
Based on the level of CPU performance improvement over the past few years, the Geekbench 5 single-core score is expected to be between 2,100 and 2,200, and the multi-core score is expected to be in the low 6,000s. Since Geekbench 6 was released not long ago, there is no accumulated benchmark data over many years to make accurate predictions, but a single-core score of 2,800 or higher and a multi-core score of 7,300 or higher are appropriate. Recently, there was leaked information claiming a single-core score of 3,019 points and a multi-core score of 7,860 points, but this possibility is not out of the question. Even when Apple upgraded the process from 7nm to 5nm for the A14 chip, the core score was higher than expected. However, the scores mentioned in this claim are completely unfounded.

Compared to other processors, the A17's expected single-core score is similar to the latest Ryzen high-end desktop CPU and the 13th generation Core i7 Intel processor, and the multi-core score is much lower. Desktop processors have more than 12 high-performance cores, but the A17 has only two high-performance cores, so it is natural. The A16 chip already has higher performance than Android smartphones equipped with the top-tier Snapdragon 8 2nd generation, and the gap is likely to widen further with the A17 chip.
If there's one lesson from the past few years, it's that Apple CPU performance improvements have been very consistent. In years where the architecture changes significantly or the manufacturing process upgrades significantly, single-core and multi-core performance improves almost linearly. It is a reasonable guess to expect a similar level of improvement this year.
