Why this score

The score adds up these parts. Each part has a weight. A part counts as the average of its sources, pulled toward 80 when there are few sources.

  1. AI power

    50% weightcounts as 75.0

    Average of 2 sources: 72.5

  2. Experts

    30% weightcounts as 69.8

    Average of 1 source: 59.5

  3. Users

    20% weightcounts as 80.0

    No sources found yet. No data yet. This part counts as 80.

Thin: only 1 review or buyer rating, so it is pulled toward the average.

80 is the field average. A part counts as 80 + (average − 80) × N ÷ (N + 1), where N is its number of sources. One source counts half of the gap from 80. No sources count as 80.

GPU memory
16 GBNo AMD Variable Graphics Memory on this chip (AMD introduced it with the Ryzen AI 300 series). Windows' documented limit for system memory used by graphics (Microsoft, 'Calculating Graphics Memory') is MIN(80% of RAM, MAX(RAM - 16 GB, 50% of RAM)) = 16 GB on 32 GB of RAM. No BIOS UMA maximum for this box was found, so the Windows figure is used. Linux GTT tuning is not documented for this iGPU.

Notes

Small CNC-aluminium 0.75 L box with OCuLink, USB4 and dual 2.5 GbE, but an older Zen 3+ chip and Radeon 680M that reviewers call slower than expected; soldered 32 GB at about 102 GB/s fits 7B-14B models only slowly.

Notebookcheck (review date 1 Apr 2026): 'average (65%)'; idle 30.9 / 31.6 / 31.6 dB(A), load 45.3 / 51.7 dB(A); power idle 7.4 / 7.7 / 7.7 W, load 52 W average (80.1 W max). TechRadar (4 Mar 2026) says 'a curious mixed bag that doesn't quite justify the asking price' and gives a 56 mm height where Notebookcheck and the shop give 63 mm; no star count was visible in the text read. Radeon 680M llama.cpp use was not documented in the pages read, so no software is listed. Release month = GMKtec EU listing date (21 Jan 2026). Memory speed source: Shop: 32 GB LPDDR5 6400 MT/s, dual-channel onboard; 128-bit bus assumed: 102.4 GB/s.
