Apple Mac Studio M5 Max, 128 GB

The successor to the M4 Max Mac Studio: the same 128 GB with a little more bandwidth and much faster prompt processing from the GPU's neural accelerators. A 70B model at Q4 runs at a usable pace, quietly, on a desk.

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.
