Whichever you pick, rest assured: every iMac here is fully tested, honestly graded and covered by a 12-month warranty — every M-series model runs the latest macOS Golden Gate, and all of them ship with a free wireless keyboard & mouse.
Every 24-inch iMac shares the same 4.5K display and design — what changes is the chip, the camera and how many screens and ports you get. The Intel 27-inch is the only way to a bigger built-in screen.
Geekbench 6 multi-core — rounded averages from Geekbench's public Mac charts. The Intel machines are shown as reference points.
