Figures are dense. Where a vendor publishes a figure it sits under the dense one and never decides a winner. Hover any precision for its definition, or read the GPU glossary.

FLOPS by Precision

What actually differs

The Instinct MI430X is the newer part: CDNA 5 (2027) against the B200's Blackwell (2024).

The Instinct MI430X carries 252 GB more memory (432 GB against 180 GB), so larger models fit on one GPU before you shard. Bandwidth is 23.3 TB/s against 7.7 TB/s, which sets the ceiling on decode speed.

Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
