What fits in memory, on one GPU
| Workload | B200 | H200 |
|---|---|---|
| LLM inference, 16-bit | ≈ 70B parameters | ≈ 55B parameters |
| LLM inference, 4-bit | ≈ 240B parameters | ≈ 180B parameters |
| Full training, mixed precision | ≈ 9B parameters | ≈ 7B parameters |
Cautious estimates counting 80% of memory for model weights; context length, batch size and framework change the real limit. Several GPUs together hold larger models.
