FLOPS by Precision

What actually differs

The Instinct MI325X is the newer part: CDNA 3 (2025) against the H200's Hopper (2024).

The Instinct MI325X carries 115 GB more memory (256 GB against 141 GB), so larger models fit on one GPU before you shard. Bandwidth is 6.0 TB/s against 4.8 TB/s, which sets the ceiling on decode speed.

Power is 1.0 kW against 700 W, and at FP32 the Instinct MI325X does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.

New to the terms? The glossary explains FP64, FP32, TF32, BF16, FP16, FP8, INT8, Sparsity and TFLOPS. For how the generations relate, see NVIDIA architectures explained.
