Research / Comparison
Compare the same category.
Manufacturer references with consistent units and explicit variant boundaries. A component is not a rack; arithmetic peaks are not model benchmarks.
Compare up to three references within one product category. Manufacturer peak figures can use different precisions and sparsity assumptions; they are not measured tokens per second.

| Cooling | SXM server integration; verify the OEM server cooling design. H100 NVL PCIe air-cooling specifications must not be applied to this SXM record. | SXM server thermal implementation depends on OEM system. The separately documented H200 NVL is a dual-slot air-cooled PCIe product. |

| Specification caveats | The headline fields select the SXM variant. H100 NVL has a different capacity, power range and form factor. Manufacturer peak Tensor Core throughput values may include structured sparsity; do not treat them as measured tokens per second. | NVIDIA retains a preliminary/specifications-may-change footnote on this page; preserve that qualification. Headline power selects SXM. NVL has a different published power limit. |
| Engineering considerations | Reserve accelerator memory for KV cache, activations and serving overhead in addition to model weights. Check server topology and collective communication behavior before choosing tensor or pipeline parallelism. | Larger GPU memory can accommodate more weights or cache, but capacity alone does not establish latency or concurrency. Confirm the serving framework, GPU driver and selected model format together. |
