FLOPS by Precision

What actually differs

The GeForce RTX 5080 is the newer part: Blackwell (2025) against the GB200's Blackwell (2024).

The GB200 carries 356 GB more memory (372 GB against 16 GB), so larger models fit on one GPU before you shard. Bandwidth is 16.0 TB/s against 960 GB/s, which sets the ceiling on decode speed.

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