NVIDIA H100 80GB SXM5

The fastest single card you can run at home, if the word card stretches to a server module on a Chinese SXM5-to-PCIe adapter board: 80 GB of HBM3 at 3.35 TB/s. Expect to feed it up to 700 W and build the cooling around it.

What it runs

For each model, grouped by vendor with the newest first: the largest quant that fits with 8K of context and the estimated speed for one user, at 8K and at 32K of context. On a card, a model too big for its memory can still run with part of the weights in system RAM; we assume 64 GB, and the speed shown accounts for it. The model you picked on the ladder is highlighted. Estimates from the spec sheet, not measurements: see how we estimate.
