IT House News on October 6, Apple launched a new iPhone 14 series model last month. One of the differences between the basic models and Pro models is the chip, because only the latter has the latest A16 chip. But a new study today believes that this chip that is considered "squeezing toothpaste" may be smaller than Apple's hints to users.
The Jason Cross of MacWorld studied the design of the A16 chip, claiming that it was basically the same as the A15. Compared with Apple's previous iPhone chip upgrade, the differences between A15 and A16 are much more limited ...
We have previously noticed that Apple refers to the A16 chip as a 4nm chip, and TSMC calls it an enhanced version of the 5nm process. In fact, it should be represented by N4, but it is essentially the same as the 5nm family. The most important improvement of it is due to the high -rise frequency.
At present, the overall data of A16 is the same as the A15: 2 high -performance cores, 4 high -efficiency cores, 5 GPU cores and 16 neural engine cores. The number of transistors has increased, but it has increased from 15 billion to nearly 16 billion -the increase is much smaller than the usual increase.
Jason Cross & nbsp; said that the architecture of its CPU and nerve engine seems to be exactly the same as the A15, which is equivalent to the high -frequency version of A15 created by Apple with N4. Different, this can also be reflected in the benchmark test.
Given that the CPU architecture does not change much, it is only running with higher main frequency (and more available memory bandwidth), we should expect most CPU benchmark tests to show 10% or fewer performance improvements.
Looking at the data of Geekbench 5 quickly, it will be found that this is indeed the same. The maximum single-core CPU performance seems to be about 8-10%higher than the A15. Multi -core performance is slightly better, but these advantages may come from an overwhelming cache improvement. After all, this is a chip -sensitive area.
If the architecture is unchanged, the GPU performance is increased by 7% to 19% and meets the expectations. However, considering that the A16 frequency is improved, the performance improvement can basically reach the consistency of the 50% memory bandwidth provided by the LPDDR5 memory.
He believes that the A16 chip is only an incremental improvement of A15, similar to A15+, which explains the iPhone 14 basic models with "action mode, photon engine and 4K movie mode".
The IT House learned that Apple officially introduced that the A16 bionic chip consists of two high -performance cores and 4 high -energy core cores brought by the speed increase of 40%. The image processor, the memory bandwidth is increased by up to 50%, which is extremely suitable for running graphic dense games and APPs. The processing capacity of the new 16 nuclear neural network engine is as high Provide higher performance in low conditions to achieve battery life of all -weather batteries.
