Need more low-level details to see if Apples claims actually hold any water... On the CPU front, mobile chips have been beating Jaguar for years.
It's almost surely based on half-precision floats.
Apple claims the A12X to be twice as fast graphically as the A10X, which was slower than the 820 and 821 Snapdragons on graphic benchmarks. In turn, we know those two are rated at about 410 - 520 single precision GFLOPS. Besides, if that were wrong and it were indeed FP32, Apple wouldn't pass the chance of claiming it was faster than the PS4 using FP16 as well, they surely love their marketing claims, after all.
I've read somewhere that FP16 is sort of enough for mobile, but you probably know better if that claim holds water or not.
