What actually differs
Both GPUs launched in 2024: the GH200 on Hopper and the H200 on Hopper.
Dense throughput for the GH200 against the H200: FP64 34 vs 30 TFLOPS, FP32 67 vs 60 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 144 GB against 141 GB, fed at 4.9 TB/s versus 4.8 TB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
Power budgets are 1.0 kW for the GH200 and 600 W for the H200. At FP32 that works out to 0.07 against 0.10 TFLOPS per watt.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
Frequently asked questions
Is the GH200 faster than the H200?
At FP32 precision the GH200 reaches 67 TFLOPS dense against 60 TFLOPS for the H200. The performance table on this page lists every published precision for both GPUs.
Which has more memory, the GH200 or the H200?
The GH200 carries 144 GB of memory versus 141 GB for the H200. Memory bandwidth is 4.9 TB/s for the GH200 and 4.8 TB/s for the H200.
