A12X has reached parity or better with Intel in terms of integer performance, but what about floating point? Even if they are way behind Intel in that regard, I could see Apple making a desktop version with a beefy fp unit that a phone SOC wouldn't need.
- baybal2 8y agoFloating point is not a totem animal of the computing world anymore. If you have a lot of FP math to do, a specialised accelerator will do that 100 times faster than CPU. Integer math is on the other side is what the most of programs you use every day are made of. And their complex, branching rich code is near impossible to feed to any specialised DSP. Modern CPUs must be compared on integer math and logical operations performance, followed by their IO performance. What an average user understands as performance today is really (integer perf + logic op perf) * effective I/O throughput.
