What is the NVIDIA B200?

The B200 is a GPU from NVIDIA on the Blackwell architecture, an accelerator for AI training, inference and high-performance computing. It is an SXM module, the mezzanine format used in dense multi-GPU servers. B200 full specifications →

Can I rent the B200 in the cloud?

Yes. Cloud providers tracked by Flopper rent the B200 by the hour, and the pricing page compares their current rates and the price history side by side. B200 rental prices →

How does the B200 compare with other accelerators?

This page sets the B200 against the GB200. Both parts launched in the same year. Both are NVIDIA parts, and both ship as an SXM module, so they fit the same class of system. Flopper also compares it head to head with the A100 SXM4 80GB, B100 SXM 192GB and B300 SXM 262GB, across every published precision, memory and power. B200 vs A100 SXM4 80GB →

Figures are dense. Where a vendor publishes a figure it sits under the dense one and never decides a winner. Hover any precision for its definition, or read the GPU glossary.

FLOPS by Precision

What actually differs

Both launched in 2024, the B200 on Blackwell and the GB200 on Blackwell.

The GB200 carries 6 GB more memory (186 GB against 180 GB), so larger models fit on one GPU before you shard. Bandwidth is 7.7 TB/s against 8.0 TB/s, which sets the ceiling on decode speed.

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

New to the terms? The glossary explains FP64, FP32, TF32, BF16, FP16, FP8, FP4, INT8, Sparsity and TFLOPS. For how the generations relate, see NVIDIA architectures explained.

Frequently asked questions

Is the B200 faster than the GB200?

At FP8 precision the GB200 reaches 5,000 TFLOPS dense against 4,500 TFLOPS for the B200. The performance table on this page lists every published precision for both GPUs.

Which should you choose, the B200 or the GB200?

Choose the GB200 for training and high-throughput inference: it has 11% more FP8 throughput than the B200. It also carries 6 GB more memory, so larger models fit on one GPU before you shard.

Which has more memory, the B200 or the GB200?

The GB200 carries 186 GB of memory versus 180 GB for the B200. Memory bandwidth is 7.7 TB/s for the B200 and 8.0 TB/s for the GB200.
