Updated September 2026

Data from Amazon and official Geekom and GMKtec sites.

2026 verdict

Winner

$1299.00

Newer platform, longer warranty: the Geekom GT1 Mega Ultra 5 beats the GMKtec NucBox M2 Pro S (16GB + 1TB) on warranty, memory type, memory speed and memory capacity, running a Core Ultra 5 125H with faster DDR5 against the M2 Pro S's older 11th Gen Core i7-1185G7 on DDR4. The GT1 Mega Ultra 5 doubles the M2 Pro S's memory at 32GB and backs it with a three-year warranty against one year, a meaningful gap for anyone planning to keep the machine for years. The M2 Pro S counters only on price, which still makes it a fair pick for buyers who need nothing more than a basic Windows desktop. Buyers who want current-generation Intel silicon, more memory and the longer warranty should choose the Geekom GT1 Mega Ultra 5; buyers on a tighter budget should stick with the GMKtec NucBox M2 Pro S.
