Out of the four systems announced so far, only HP's Z2 Mini supports ECC memory. The Framework Desktop does not support it, and there is no information about GMTec.
Many forget that this miniPC is aimed at AI loads thanks to the 96 GB of VRAM allocation.
From a normal/gamer user perspective, it basically has the same performance as the G7 Pt (which is actually impressive for a miniPC), but using half the power (so it's a lot more silent), and it costs an arm and a leg.
Gah, I wouldn't forget benchmark numbers are actually putting the 8060S around the same level as a 3070 Ti/4060, but framerates aren't that optimist - it's only good for mid-high 1080 gameplay, certainly not good enough (not consistently at least) for 1440.
$2k for a mini PC with some exagerated claim about its APU is bound to disappoint - get a gaming laptop with dGPU instead.
The GMKtec EVO-X2 is now official in China, and it's available only in one configuration, which pairs the Ryzen AI Max+ 395 with 128 GB of RAM and 2 TB of storage. Its launch price is CNY 14,999, around $2,060.
