Data from the official Geekom and GMKtec sites.
2026 verdict
A 1TB drive against 512GB, and a 3 year warranty against 1 year, are the numbers that matter most between the Geekom GT1 Mega Ultra 5 and the GMKtec NucBox M5 Ultra (32GB + 512GB), and both favor the Geekom.
Its Intel Core Ultra 5 125H runs faster DDR5 memory than the GMKtec's DDR4 and earns a noticeably higher owner rating too, though the GMKtec NucBox M5 Ultra (32GB + 512GB) undercuts it on price. Both ship with 32GB of memory, but the Geekom adds Wi-Fi 7, dual USB4 ports, an SD card reader and a Kensington lock the GMKtec skips entirely. Buyers who want more storage, faster memory and stronger support should choose the Geekom GT1 Mega Ultra 5; those chasing the lowest sticker price can still get a workable desktop from the GMKtec NucBox M5 Ultra (32GB + 512GB).
