AMD MI355X Beats NVIDIA B200 in Kimi K3 Deployment with 952 tok/s

adrianscottcom · x · 2026-08-03

Engineers successfully deployed the Kimi K3 model on a single AMD MI355X server. Leveraging AMD's memory advantage, the single node achieved a total throughput of 952 tok/s and 118 tok/s for a single user.

Tests show this node's total throughput is nearly 4x that of a 16×B200 setup, with better performance per dollar than both B200 and B300. Additionally, AMD's ROCm stack proved mature, working mostly out-of-the-box with only minor fixes needed.
