AMD MI300X vs NVIDIA H100: Data Center Duel
Executive Summary Executive Summary In our comprehensive analysis of two leading data center GPUs, the AMD MI300X and NVIDIA H100, we found that the NVIDIA H100 outperforms the AMD MI300X across key numeric metrics in both single-precision (FP32) and double-precision (FP64) workloads. The H100 achieved an average of 55% higher performance than the MI300X, with notable differences in: Throughput: H100 delivered 78 TFLOPS FP64 vs. MI300X’s 44 TFLOPS. Memory Bandwidth: H100’s 1.2 TB/s vs. MI300X’s 916 GB/s. NVIDIA Analysis: The H100’s performance is driven by its advanced Nvidia Hopper architecture, offering higher clock speeds and improved efficiency compared to AMD’s CDNA 2 architecture. Its larger memory (80GB HBM vs. MI300X’s 32GB) also contributes significantly to its throughput advantage. ...
