AMD Instinct MI300X

192 GB of HBM3 at 5.3 TB/s on one module, the most memory of anything here, but it is an OAM module that only lives in an 8-way server. Listed because surplus modules do surface; budget a chassis around them.

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.
