GPU comparison
B200 vs GH200.
The B200 is ahead on memory (180 GB vs 96 GB) and speed (2.3x the FP16 throughput and at least 2.0x the memory bandwidth). The GH200 makes sense when your model fits in 96 GB and its hourly price is lower.

B200: 1 GPU, 134 GB spare
GH200: 1 GPU, 50 GB spare
B200. Same GPU count, 2.3x the FP16 throughput.
Train on a full node
FP16 tensor throughput per node
B200: 8x, 18,000 TFLOPS, NVLink
GH200: 1x, 990 TFLOPS
B200. 8 GPUs per node, not 1.
Throughput per watt
FP16 TFLOPS per 100 W of TDP
B200: 225 TFLOPS per 100 W
GH200: Superchip power, not a GPU TDP
Either. Not comparable.
