- Volta refers to SM 7.0, Turing to SM 7.5, Ampere to SM 8.0/8.6, Ada to SM 8.9, and Hopper to SM 9.0.
- "✅︎" indicates that the quantization method is supported on the specified hardware.
- "✗" indicates that the quantization method is not supported on the specified hardware.

```{note}
This compatibility chart is subject to change as vLLM continues to evolve and expand its support for different hardware platforms and quantization methods.

For the most up-to-date information on hardware support and quantization methods, please refer to <gh-dir:vllm/model_executor/layers/quantization> or consult with the vLLM development team.
