NVFP4 quantization offers 2.3x faster decoding on Ada GPUs, matching BF16 quality

By PulseAugur Editorial · [1 sources] ·

A technical blog post compares the performance of different quantization formats for large language models on an NVIDIA Ada GPU. The analysis focuses on NVFP4, FP8, and GGUF, finding that NVFP4 offers a significant speed advantage for decoding, being 2.3 times faster than bfloat16 while maintaining comparable quality on the GSM8K benchmark. FP8 excels when multiplications are performed in 8 bits, and MXFP8 shows the highest fidelity to bfloat16 in token-by-token generation. AI

IMPACT Optimizations in quantization formats like NVFP4 can lead to faster inference and reduced hardware requirements for LLMs.

    NVFP4 vs FP8 vs GGUF on a 16 GB Ada GPU: NVFP4 decodes 2.3x faster and ties BF16 on GSM8K

    <p>When you type «nvfp4 vs» into Google it completes with «fp8», «gguf», «q4_k_m» and «bf16». The usual answer compares different models quantized by different people. On October 16 NVIDIA released Nemotron Labs Dory 1.0 4B in BF16, NVFP4, MXFP8 and GGUF at once, so I measured th…
