UnverifiedFP8 data volume is half that of FP16, and the H100's FP8 Tensor Core compute throughput is twice that of FP16 (approximately 1979 TFLOPS).72% similarUnverifiedThe official provides FP8 quantized checkpoints (Hy3-FP8); FP8 quantization can halve memory usage and memory bandwidth requirements compared to FP16.69% similarUnverifiedQuantization reduces FP32 (32-bit) weights to INT4 (4-bit), achieving a theoretical compression ratio of 8×, but introduces precision loss.67% similarVerifiedQuantization technology compresses model weights from FP32/FP16 to low-precision formats such as INT8/INT4, which can reduce model size by 50%–75%.67% similarUnverifiedThe B200's FP4 peak compute can reach approximately 9 PFLOPS (sparse mode), representing up to an 8x improvement over FP16.65% similar
