功耗差多少？

GPU性能至少差3倍。
PS4 的7850-7870之间，X分可以到2300.
NS显卡性能只有GT750的一半，频率还低很多。GT750的X分是1600，NS只有800左右.

看标题就知道是Geekbench

Wilco, geekbench has apparently replaced dhrystone as your favourite useless benchmark.

Geekbench is SH*T.

It actually seems to have gotten worse with version 3, which you should be aware of. 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.

And quite frankly, it's not even just the crypto ones. Looking at the other GB3 "benchmarks", they are mainly small kernels: not really much different from dhrystone. I suspect most of them have a code footprint that basically fits in a L1I cache.

不懂，凑热闹
多核性能差距在50% 是不是可以理解成switch的机能是PS4的一半？
switch=PS4÷2=PS2？
