Sourcing and disambiguation notes

Same 273GB/s as the 16-core M4 Pro -- Apple quotes one figure for both bins -- so what this configuration adds over the 24GB mini is headroom, not speed: it holds a 27B-class model at 4-bit that the smaller machine cannot. Price left empty deliberately: this is a build-to-order memory upgrade, and Apple's Mac mini buy page renders only its standard tiles ($799 / $1,599 / $1,799) in markup that can be read at the source, so the configured price could not be confirmed without trusting a figure nothing on the page states.

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 verified, single-source and estimated mean, and the same rows with every filter and sort in the benchmarks explorer.

Speed over time

What it can run

Fit is arithmetic, not a measurement — how it is computed. Against 48 GB; models that fit are listed largest first.
