Sourcing and disambiguation notes

The faster of the two M4 Max bins: Apple's Mac Studio tech specs give 410GB/s for the 32-core GPU and 546GB/s for the 40-core, so on this chip the extra GPU cores buy decode throughput as well as prefill. The price is the second of the four figures the Mac Studio buy page carries ($2,499 / $3,499 / $5,299 / $6,799); the page renders its configuration labels in script, so the mapping was fixed by reading the lowest tile's configuration (M4 Max 14-core CPU, 32-core GPU, 36GB, 512GB) and taking the tiles in ascending order, two M4 Max then two M3 Ultra.

Measurements

Decode is token generation — the speed you feel while an answer streams. Prefill is prompt processing — the wait before it starts. Why bandwidth predicts decode speed.

What it can run

Fit is arithmetic, not a measurement — how it is computed. Against 64 GB; models that fit are listed largest first.
