FLOPS by Precision

What actually differs

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

The GB200 carries 192 GB more memory (372 GB against 180 GB), so larger models fit on one GPU before you shard. Bandwidth is 7.7 TB/s against 16.0 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 10,000 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 2.2x the FP8 throughput of the B200. It also carries 192 GB more memory, so larger models fit on one GPU before you shard. Packaging differs too: the B200 is an SXM module while the GB200 is a superchip, so check what your servers accept.

Which has more memory, the B200 or the GB200?

The GB200 carries 372 GB of memory versus 180 GB for the B200. Memory bandwidth is 7.7 TB/s for the B200 and 16.0 TB/s for the GB200.

How much do the B200 and the GB200 cost to rent?

Live cloud listings tracked by Flopper price the B200 from $0.99 per GPU-hour across 24 providers, and no live listings yet for the GB200. The rental section on this page links to every provider, rate and the price history for each GPU.
