So if you believe it is unfair that the x264 test doesn't allow using hand tuned SIMD assembly, would you also allow use of on chip h.264 hardware, as well as Apple's IPU or NPU if those proved more appropriate for some other benchmark instead of using their CPU cores?
Or are you going to come up with some tortured logic to claim using any *CPU* resources is OK, but using other blocks on an SoC isn't fair to CPUs being tested that aren't part of an SoC?
