I’m an AMD fanboy, and just built a new Ryzen box. I’d be curious to see if there is a difference in accuracy running the two kernels on AMD hardware.
Maybe it is faster but less accurate to run the intel kernel on AMD hardware.
- Tuna-Fish 6y agoThere is no difference. The operations these kernels use are all well-defined and work identically on all CPUs that implement them. In general, FP/SIMD is not nearly as much of a crapshoot as people seem to expect it to be. Beyond timings, there are generally no user-space visible differences in operation between any AVX/SSE instructions in Intel/AMD cpus.
