GPU comparison

H200 NVL vs RTX 4090.

The H200 NVL is ahead on memory (141 GB vs 24 GB) and speed (5.1x the FP16 throughput and 4.8x the memory bandwidth). The RTX 4090 makes sense when your model fits in 24 GB and its hourly price is lower.

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

    H200 NVL: 1 GPU, 71 GB spare

    RTX 4090: 4 GPUs, more than one 2x node

    H200 NVL. Fits on one GPU.

  • Serve an 8B model in 16-bit weights

    16 GB of 16-bit weights

    H200 NVL: 1 GPU, 125 GB spare

    RTX 4090: 1 GPU, 8 GB spare

    H200 NVL. Same GPU count, 4.8x the memory bandwidth.

  • Fine-tune a 70B model with QLoRA

    About 46 GB with 4-bit weights

    H200 NVL: 1 GPU, 95 GB spare

    RTX 4090: 2 GPUs (48 GB)

    H200 NVL. Fits on one GPU.

  • Train on a full node

    FP16 tensor throughput per node

    H200 NVL: 8x, 6,680 TFLOPS, NVLink in groups of 4

    RTX 4090: 2x, 330 TFLOPS

    H200 NVL. 8 GPUs per node, not 2.

  • Throughput per watt

    FP16 TFLOPS per 100 W of TDP

    H200 NVL: 139 TFLOPS per 100 W

    RTX 4090: 37 TFLOPS per 100 W

    H200 NVL. 3.8x the FP16 per watt.
