MI300X vs H100/H200 Benchmark Part 1: Training — Real-World Performance Lags Behind Theoretical Specs
Summary
SemiAnalysis benchmarks the MI300X against Nvidia's H100/H200, showing that despite AMD's memory bandwidth advantages, real-world training performance lags due to software issues and incomplete integration. The article highlights significant out-of-the-box usability gaps, reliance on custom development images, and ongoing software tuning, with implications for TCO and multi-node scaling. It also discusses benchmarking methodology, GA vs beta builds, and recommendations for AMD to close the performance gap.
