DiffusionGemma 26B Challenges GH200 Performance Limits
A technical deep-dive reveals that the DiffusionGemma 26B model, when run on NVIDIA's GH200 Grace Hopper platform with vLLM optimization, achieves exceptional performance. The setup demonstrated a generation throughput of 1180 tokens/sec for short contexts and handled up to 32,000 tokens with acceptable latency, significantly outperforming previous tests on M2 Max hardware. While the model's memory footprint on the GH200's HBM3 is substantial, leaving limited room for KV cache, the platform's overall architecture and vLLM's batching capabilities enable impressive concurrent throughput, far exceeding that of the M2 Max.
