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 Blackhole carries 8 GB more memory (32 GB against 24 GB), so larger models fit on one GPU before you shard. Bandwidth is 576 GB/s against 512 GB/s, which sets the ceiling on decode speed.

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