What is the NVIDIA GB200?

The GB200 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. GB200 full specifications →

Can I rent the GB200 in the cloud?

Yes. Cloud providers tracked by Flopper rent the GB200 by the hour, and the pricing page compares their current rates and the price history side by side. GB200 rental prices →

How does the GB200 compare with other accelerators?

This page sets the GB200 against the GB300. The GB200 is the older generation of the two. Both are NVIDIA parts, and both ship as an SXM module, so they fit the same class of system. The compare tool builds the same comparison for any two parts in the catalogue. All GPU comparisons →

Where do the GB200 figures come from?

Every GB200 figure on this page traces to NVIDIA's own datasheet or specification table. How Flopper verifies specifications →

FLOPS by Precision

What actually differs

The GB300 is the newer part: Blackwell Ultra (2025) against the GB200's Blackwell (2024).

The GB300 carries 102 GB more memory (288 GB against 186 GB), so larger models fit on one GPU before you shard. Bandwidth is 8.0 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

What is better, the GB200 or the GB300?

They are close on paper: both deliver about 5,000 TFLOPS of dense FP8 throughput. Memory, bandwidth, and power are the deciding differences.

Which should you choose, the GB200 or the GB300?

On raw FP8 throughput the GB200 and the GB300 are level, so the decision rests on memory, power and price. Choose the GB300 when the model has to fit on one GPU: it carries 102 GB more memory.

Which has more memory, the GB200 or the GB300?

The GB300 carries 288 GB of memory versus 186 GB for the GB200. Memory bandwidth is 8.0 TB/s for the GB200 and 8.0 TB/s for the GB300.

How much do the GB200 and the GB300 cost to rent?

Live cloud listings tracked by Flopper price the GB200 from $10.50 per GPU-hour across 2 providers, and the GB300 from $5.74 per GPU-hour across 2 providers. The rental section on this page links to every provider, rate and the price history for each GPU.
