- pixelpoet 24d agoThat's what I mean though- in the Core 2 Duo vs K8 / Athlon days, Intel was much slower for denormals and subnormals than AMD. I'm not sure why but I thought this was common knowledge.
- augment_me 24d agoThis is true on most hardware. Running ftz on H100s or B200 gives a free 10-20% boost for GEMM-epilogue workload
