FLOPS by Precision

What actually differs

The GH200 is the newer part: Hopper (2023) against the H100's Hopper (2022).

The GH200 carries 16 GB more memory (96 GB against 80 GB), so larger models fit on one GPU before you shard. Bandwidth is 4.0 TB/s against 3.4 TB/s, which sets the ceiling on decode speed.

Power is 1.0 kW against 700 W, and at FP32 the H100 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.

Frequently asked questions

Is the GH200 faster than the H100?

They are close on paper: both deliver about 1,979 TFLOPS of dense FP8 throughput. Memory, bandwidth, and power are the deciding differences.

Which should you choose, the GH200 or the H100?

On raw FP8 throughput the GH200 and the H100 are level, so the decision rests on memory, power and price. Choose the GH200 when the model has to fit on one GPU: it carries 16 GB more memory. The H100 draws 300 W less power, which matters in an air-cooled or power-capped rack. Packaging differs too: the GH200 is a superchip while the H100 is an SXM module, so check what your servers accept.

Which has more memory, the GH200 or the H100?

The GH200 carries 96 GB of memory versus 80 GB for the H100. Memory bandwidth is 4.0 TB/s for the GH200 and 3.4 TB/s for the H100.

How much power do the GH200 and the H100 draw?

The GH200 is rated at 1.0 kW TDP and the H100 at 700 W. On FP32 throughput per watt, the H100 is the more efficient part.

How much do the GH200 and the H100 cost to rent?

Live cloud listings tracked by Flopper price the GH200 from $2.29 per GPU-hour across 4 providers, and the H100 from $1.73 per GPU-hour across 34 providers. The rental section on this page links to every provider, rate and the price history for each GPU.
