NVIDIA RTX PRO 6000 Blackwell Workstation Edition vs NVIDIA B200 SXM 180GB

Both GPUs launched in 2025: the RTX PRO 6000 Blackwell on Blackwell and the B200 on Blackwell.

Dense throughput for the RTX PRO 6000 Blackwell against the B200: FP32 126 vs 75 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 96 GB against 180 GB, fed at 1.8 TB/s versus 7.7 TB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.

Power budgets are 600 W for the RTX PRO 6000 Blackwell and 1.0 kW for the B200. At FP32 that works out to 0.21 against 0.07 TFLOPS per watt.

For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
