How does AMD Instinct MI300X benchmark against H100?

回答

Benchmarked performance on AMD Instinct MI300X: 1,307 TFLOPS in FP16, 163.4 TFLOPS in FP32, 5,300 GB/s memory bandwidth, 192 GB VRAM.

For the workloads most engineers care about — model training transformer-family models, serving LLM low-latency inference, running diffusion and vision pipelines — those specs are enough to sustain batch sizes that keep tensor cores busy. Expect wall-clock gains versus previous-generation CDNA 3 cards to range from 1.5x to 3x depending on workload shape.
