 FP8
 ==================
 
-vLLM supports FP8 (8-bit floating point) computation using hardware acceleration on GPUs such as Nvidia H100 and AMD MI300x. Currently, only Hopper and Ada Lovelace GPUs are supported. 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.

+Notes:
+^^^^^^
+
+- 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.
+
+Please note that this compatibility chart may be subject to change as vLLM continues to evolve and expand its support for different hardware platforms and quantization methods.
