Context Before
Turning to AMD, we find that the biggest issue with inference on their systems and using their software is composability ↗. That is, many of AMDs inference optimization implementations work well in isolation, but when combined with other optimizations, the result is not as competitive as one would expect. Specifically, the composability of disagg prefill, wideEP and FP4 inference optimizations needs significant improvement.
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
Evidence
Nvidia’s GB300 NVL72 doesn’t disappoint
Context After
At GTC 2024, Jensen claimed that Blackwell will deliver up to 30x perf on inference compared to H100, Jensen under promised & overdelivered on Blackwell inference performance. This should curtail the instances of analysts cracking “Jensen Math” jokes for some time.
