GPU comparison
H100 vs GH200.
Pick the GH200 for memory: 96 GB vs 80 GB, with up to 19% more memory bandwidth. FP16 speed is close (up to 989 TFLOPS vs 990 TFLOPS), so for models under 80 GB pick by price.

Which is better for
Which to pick for each job. Memory fit and throughput, from the datasheets.
Hold a 70B model in 8-bit weights
70 GB of 8-bit weights
H100: 1 GPU, 10 GB spare
GH200: 1 GPU, 26 GB spare
GH200. Same GPU count, up to 19% more memory bandwidth.
Serve an 8B model in 16-bit weights
16 GB of 16-bit weights
H100: 1 GPU, 64 GB spare
GH200: 1 GPU, 80 GB spare
GH200. Same GPU count, up to 19% more memory bandwidth.

About 46 GB with 4-bit weights
H100: 1 GPU, 34 GB spare
GH200: 1 GPU, 50 GB spare
Either. Fits on one GPU of either.
Train on a full node
FP16 tensor throughput per node
H100: 8x, up to 7,912 TFLOPS
GH200: 1x, 990 TFLOPS
H100. 8 GPUs per node, not 1.
Throughput per watt
FP16 TFLOPS per 100 W of TDP
H100: Varies by card
GH200: Superchip power, not a GPU TDP
Either. Not comparable.
