vLLM supports FP8 (8-bit floating point) weight and activation quantization using hardware acceleration on GPUs such as Nvidia H100 and AMD MI300x.
Currently, only Hopper and Ada Lovelace GPUs are officially supported for W8A8.
Ampere GPUs are supported for W8A16 (weight-only FP8) utilizing Marlin kernels.
Turing/Ampere GPUs are supported for W8A16 (weight-only FP8) utilizing Marlin kernels.
Quantization of models with FP8 allows for a 2x reduction in model memory requirements and up to a 1.6x improvement in throughput with minimal impact on accuracy.
