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.

Rent either on Runcrate

Live hourly price, then per GB of memory and per 100 FP16 TFLOPS.

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.

  • Fine-tune a 70B model with QLoRA

    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.
