NVIDIA GB200 Grace Blackwell Superchip 372GB vs NVIDIA RTX PRO 6000 Blackwell Server Edition

The RTX PRO 6000 Blackwell is the newer part: Blackwell, launched in 2025, against the GB200's Blackwell from 2024. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.

Dense throughput for the GB200 against the RTX PRO 6000 Blackwell: FP32 160 vs 120 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 372 GB against 96 GB, fed at 16.0 TB/s versus 1.6 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.

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.
