FLOPS by Precision

What actually differs

The RTX PRO 5500 Blackwell is the newer part: Blackwell (2026) against the B200's Blackwell (2024).

The B200 carries 96 GB more memory (180 GB against 84 GB), so larger models fit on one GPU before you shard. Bandwidth is 7.7 TB/s against 1.4 TB/s, which sets the ceiling on decode speed.

Power is 1.0 kW against 600 W, and at FP32 the B200 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
