NVFP4: Efficient and Accurate Low-Precision Inference
research

NVIDIA introduces NVFP4, a 4-bit floating-point format for NVIDIA Blackwell GPUs that achieves efficient low-precision inference while maintaining model accuracy through a two-level scaling strategy combining fine-grained E4M3 block-level and FP32 tensor-level scaling, reducing memory footprint by 3.5x versus FP16 with less than 1% accuracy degradation on language models.

To Sparsify or to Quantize: A Hardware Architecture View
research

A technical analysis of sparsity versus quantization as hardware optimization strategies for neural networks, exploring architectural challenges (unstructured sparse data chaos vs. quantization metadata overhead) and current compromises (structured sparsity patterns and algorithmic co-design techniques) used in modern AI accelerators.
