The A16 processor found in the iPhone 14 Pro and 14 Pro Max is actually an improved A15 communication chip, writes Macworld. The publication believes that the name A15 + suits it better.
Apple claims that the A16 is the world’s first 4nm processor. But TSMC, the company that makes the chips for Apple, called it “N5’s enhanced human technology.” That is, this is not a 4 nm process technology in the literal sense, but a modified version of the 5 nm process technology.
This is also evidenced by the number of transistors: in the A15 there are 15 billion of them, in the A16 – 16 billion. This is a significantly smaller jump than usual when Apple measures the technical process.
Macworld suggests that the CPU and Neural Engine are either identified or nearly the same architecture as in the A15. The increased performance comes from the increased frequency, not from the new architecture. The same applies to the graphics chip.
The most notable change to the standard is the switch from LPDDR4x to LPDDR5 RAM. Therefore, its throughput increased by 50%.
Another circumstantial evidence that the A16 is only a marginally improved sociology of the A15 comes from the capability of the iPhone 14 and 14 Pro.
This year, the camera version of the base iPhone and Pro- is not very important. iPhone 14 supports 4K cinematic mode, video action mode, and the new Photonic Engine imaging mode. The only features of the iPhone 14 Pro camera are covered by the presence of a telephoto module and support for ProRAW and ProRes formats. [Macworld]
