Source notes for H100 SXM
Datasheet and product page (https://www.nvidia.com/en-us/data-center/h100/) list FP16/BF16 Tensor 1,979 TFLOPS and FP8 3,958 TFLOPS with sparsity; dense 989.4 / 1978.9 taken from the H100 Tensor Core GPU Architecture whitepaper V1.04, Table 3 (https://dam-cdn.nvd.orangelogic.com/AssetLink/705n6ur546g0uk43w0117r17n8042d73.pdf). HBM3 per whitepaper (5120-bit HBM3, 3352 GB/sec). TDP up to 700W (configurable). Also PCIe Gen5 128 GB/s.
Compute figures are dense, without sparsity. NVIDIA source for H100 SXM Checked 8 Nov 2026.

How many do you need to hold a model?
| Model size | FP16 / BF16 | FP8 | INT4 |
|---|---|---|---|
| 8B parameters | 1 GPU16 GB of weights | 1 GPU8 GB of weights | 1 GPU4 GB of weights |
| 70B parameters | 3 GPUs140 GB of weights | 2 GPUs70 GB of weights | 1 GPU35 GB of weights |
| 405B parameters | 13 GPUs810 GB of weights | 7 GPUs405 GB of weights | 4 GPUs203 GB of weights |
GPUs = parameters × bytes per parameter × 1.2 headroom ÷ 80 GB, rounded up. This covers weights only. Long contexts, large batches, and training need much more memory.

Per GPU-hour divides a machine's hourly price by its GPU count, so single GPUs and 8-GPU nodes compare fairly. The billed price is what one machine costs per hour. Storage, network transfer, and minimum terms can add to the bill.
