Blackwell-Native NVFP4 Quantization Increases Qwen2.5 27B Prefill Speed by 50%

A new Blackwell-native NVFP4 quantization for Qwen 27B achieves 6250 t/s on prefill benchmarks, outperforming standard Q4 quants by 50%. Testing on an RTX 5090 shows it runs 4-7% faster than existing NVFP4 implementations and includes a quantized MTP draft head for a 15% speedup.
