GMKtec K13

What owners say

This is the most frugal machine we have looked at: 0.03 W switched off, 0.39 W on standby, and 31.6 W at the wall while running Cyberpunk 2077 at its ultra preset. A Beelink we reviewed draws 4.8 W doing nothing at all. It is also the quietest at idle in its reviewer's entire comparison table, at 24.5 dB(A) against a 23.3 dB(A) room. Under load that reverses: the fan is high-pitched, ramps quickly, and every change in speed is audible, and it is the one thing the reviewer who measured it keeps returning to. Two limits worth knowing before you buy. The memory sits inside the processor package, so the sixteen gigabytes it ships with are the sixteen gigabytes it will always have; a thirty-two gigabyte K13 does not exist, and would be a different processor. And the underside reaches 50.6 °C against a class average of 36, so where you stand it matters. The maker publishes no firmware for this machine at all: we checked its download page, its European mirror and the store that serves every file it hosts, and found one firmware image across roughly twenty-five product folders, for a different model.

For whom

A small, very efficient desktop for office and creative work, and for anyone who cares what a machine costs to leave switched on.

Not for

Loading it hard in a quiet room, adding memory later, and anyone who expects firmware updates.
