Context Before
While performance is competitive on AMD when enabling just a subset of the SOTA inference optimizations, enabling all three major optimizations that labs use, AMD’s performance is currently not competitive with Nvidia’s. We strongly recommend to AMD that they focus heavily on composability of different inference optimizations. We have been told that AMD will start focusing on software composability of FP4+distributed inferencing across their whole software stack. This will happen after Chinese New Year as most of their disagg prefill+wideEP 10x inference engineers are based in China
Nvidia’s GB300 NVL72 doesn’t disappoint. It achieves up to 100x on FP8 vs FP4 compared to even a strong H100 disagg+wideEP+MTP baseline and 65x on FP8 vs FP8. On H100 vs GB200 NVL72, we see up to 55x realized performance difference at 75 tok/s/user. Rack scale Blackwell NVL72 is framemogging hopper and makes hopper looks like it is jestermaxxing. As Jensen said at GTC 2025, he is chief revenue destroyer. ↗
