AMD ATOM Engine
Evidence
Atom can deliver slightly better single node performance
Context After
Furthermore, maintainers of open-source inference engines like vLLM are disappointed in AMD due to a lack of engineering and GPU resources provided by AMD. For example, Simon Mo, lead vLLM maintainer, states in this GitHub RFC that there is still no working MI355X that he can add to vLLM CI, hence the poor user experience. There are currently zero Mi355X tests on vLLM, while NVIDIA’s B200 has many tests on vLLM. Similarly, there are still not enough MI300X CI machines on vLLM. Upstream vLLM needs at least 20 more MI300 machines, 20 more MI325 machines and 20 more MI355X machines to reach the same level of usability as CUDA.
We at SemiAnalysis have been trying to get AMD to contribute more compute to vLLM and have had some success on that within the couple weeks. vLLM will start to get a couple of MI355X machines such that they can bring their CI test parity from 0% to non-0%. We will talk more about AMD’s previous lackluster contribution towards vLLM, SGLang, PyTorch CI machine situation & how Anush started to fix it in our upcoming State of AMD article. At SemiAnalysis, we will have internal dashboard to track the # of tests & quality of tests that AMD & NVIDIA runs on vLLM, SGLang, PyTorch, & JAX.
