Apple A15 performance detailed testing: an indicator comparable to AMD Rayon 9! Android has no taillights

The iPhone 13 series and the sixth-generation iPad Mini all feature Apple's latest A15 SoC.

Although it has a taste of toothpaste compared with its predecessor A14, it still has a deep foundation and top-notch strength. It has also been extensively tested by AnandTech.


A brief introduction to A15 architecture

The A15 continues to integrate six core cpus, including two high performance large cores, four low power small cores, and 4-5 GPU cores at the same time, as well as new display pipeline, video encoder, video decoder, ISP, as well as doubling system cache and stronger neural network.

The CPU,The large core microarchitecture is virtually unchanged from the A14, at least in terms of throughput and latency on the back end.

There are more small core changes, such as integer ALUs going from 3 to 4, and TLB upgrades for the cache subsystem.


Operation frequency is comprehensively improved, single large core can reach the highest3240MHz, 242MHz higher than A14, and two large cores in parallel3180MHz, increased 290MHz, small nuclei are the highest2016MHz, increased by 193MHz.

A15 manufacturing process is TSMC 5nm, guess it should be the enhanced version of N5P, also contribute to the frequency increase.



The system cache was doubled from 16MB on the A13/A14 to 32MB, with the large core level 2 cache halved from 8MB to 12MBThat's larger than the total cache of other soCs like the Snapdragon 888 and on par with the Apple M1, but only serving two cores instead of four.

The small core level 2 cache remains at 4MB, but with TLB.
