FLOPS by Precision

What actually differs

The GeForce RTX 5090 is the newer part: Blackwell (2025) against the B200's Blackwell (2024).

The B200 carries 148 GB more memory (180 GB against 32 GB), so larger models fit on one GPU before you shard. Bandwidth is 7.7 TB/s against 1.8 TB/s, which sets the ceiling on decode speed.

Power is 1.0 kW against 575 W, and at FP32 the GeForce RTX 5090 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
