Do they just keep adding new tests that iPhones have hardware acceleration for? Linus Torvalds complained about Geekbench awhile back because many of the integer workloads were offloaded to the crypto unit.

> On ARM64, that SHA1 performance is hardware-assisted. I don't know if SHA2 is too, but Aarch64 does apparently do SHA256 in the crypto unit, so it might be fully or partially so. And on both ARM and x86, the AES numbers are similarly just about the crypto unit. So basically a quarter to a third of the "integer" workloads are just utter BS. They are not comparable across architectures due to the crypto units, and even within one architecture the numbers just don't mean much of anything.
- kramerger 4y agoWhen phone makers switched to arm64 a lot of early fanboy benchmarks were AES and SHA only, showing impressive gains and ignoring stuff first gen arm64 was actually slower at.
