A user shares their experience running DiffusionGemma 26B on a 4090 GPU via vLLM, achieving up to 475t/s but noting drawbacks like single-user limitation, lower accuracy, and short context, concluding it's not worth using over the regular 26B model.
DiffusionGemma is out; it's compute-bound and 4x faster than other Gemma-4 models with 1k tok/s on H100, and excels at coding tasks including 3D generation and front-end.
This post presents benchmark results and tuning parameters for running DiffusionGemma 26B A4B GGUF models on an RTX 5090 GPU, showing up to 44% speedup via optimized temperature settings and quantization choices.
A benchmark shows that using vLLM with DFlash speculative decoding boosts Gemma 4 26B inference to ~578 tokens per second on a single RTX 5090, achieving a 2.56x speedup over baseline.
Internal testing of DiffusionGemma reveals significant performance differences between H100 and A100 GPUs under real-world workloads, with H100s scaling much better under concurrency, and efficiency varying greatly depending on workload type, raising questions about benchmark reliability.
