What is the NVIDIA H20?

The H20 is a GPU from NVIDIA on the Hopper 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. H20 full specifications →

Can I rent the H20 in the cloud?

Flopper is not tracking any live rental listings for the H20 yet. The provider directory lists the clouds that rent comparable accelerators on demand. GPU cloud providers →

How does the H20 compare with other accelerators?

This page sets the H20 against the L600. Both parts launched in the same year. This is a cross-vendor matchup, NVIDIA against Enflame; the H20 is an SXM module while the L600 is an OAM module. The compare tool builds the same comparison for any two parts in the catalogue. All GPU comparisons →

Where do the H20 figures come from?

NVIDIA published the H20 figures in marketing material rather than a datasheet, and Flopper has no independent confirmation of them. How Flopper verifies specifications →

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 2025, the H20 on Hopper and the L600 on GCU-CARA 4.

The L600 carries 3 GB more memory (144 GB against 141 GB), so larger models fit on one GPU before you shard.

Power is 400 W against 700 W, and at FP32 the H20 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.

Frequently asked questions

Which should you choose, the H20 or the L600?

Choose the L600 when the model has to fit on one GPU: it carries 3 GB more memory. The H20 draws 300 W less power, which matters in an air-cooled or power-capped rack. Packaging differs too: the H20 is an SXM module while the L600 is an OAM module, so check what your servers accept.

Which has more memory, the H20 or the L600?

The L600 carries 144 GB of memory versus 141 GB for the H20.

How much power do the H20 and the L600 draw?

The H20 is rated at 400 W TDP and the L600 at 700 W. On FP32 throughput per watt, the H20 is the more efficient part.
