A blog post from Wafer.ai details how they achieved better performance per dollar by running the Kimi K3 model on AMD's MI355X GPUs. Despite Kimi K3's massive 2.8T parameter size requiring significant VRAM, the MI355X, with its 288GB of VRAM per GPU, proved to be a cost-effective alternative to NVIDIA's B300 and B200 GPUs. While NVIDIA's hardware offered higher aggregate throughput, the MI355X provided a superior performance-per-dollar ratio, especially when considering the cost difference. The post also touches on the engineering effort required to optimize Kimi K3 for AMD's ROCm platform, including a fix for a NameError in the speculative decoding process. AI
