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 Rebel100 carries 80 GB more memory (144 GB against 64 GB), so larger models fit on one GPU before you shard. Bandwidth is 4.8 TB/s against 1.0 TB/s, which sets the ceiling on decode speed.

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