The A6 runs an eight-core Ryzen 7 6800H with Radeon 680M graphics and DDR5 memory, a noticeably more capable platform than the G3 Pro's four-core Intel Core i3-10110U on older DDR4, and it ships with double the storage at 1TB against the G3 Pro's 512GB. The G3 Pro's main draw is a lower price, along with a second free M.2 SATA bay for anyone who wants to add a drive later rather than pay for more capacity upfront. Buyers who want a genuinely capable everyday desktop with room to grow should choose the Geekom A6 (Ryzen 7 16GB + 1TB), while shoppers on a tight budget who just need a basic Windows box should pick the GMKtec NucBox G3 Pro (16GB + 512GB).

What the differences mean

Processor tier

The A6 runs an eight-core, sixteen-thread Ryzen 7 6800H. The G3 Pro runs a quad-core, four-thread Core i3-10110U. That is a large gap in multitasking and general performance headroom, not a marginal one.

Memory type

The A6 uses DDR5, the newer standard, expandable from 16GB to 64GB. The G3 Pro uses DDR4 over the same 16GB-to-64GB range, so the ceiling matches but the A6 sits on the faster platform.

Storage

1TB on the A6's single PCIe 4.0 bay against 512GB on the G3 Pro, though the G3 Pro adds a second, empty M.2 SATA bay the A6 does not have.

Connectivity

The A6 has a USB4 Type-C port and an SD card reader. The G3 Pro has neither, relying entirely on USB Type-A ports.

Warranty

Three years on the Geekom A6 (Ryzen 7 16GB + 1TB) against one year on the GMKtec NucBox G3 Pro (16GB + 512GB).

Which one to buy if

What owners say

Owners of both machines land on the same first impression, easy setup and a quiet chassis for everyday work, but the similarities mostly end there. Geekom A6 (Ryzen 7 16GB + 1TB) owners praise an eight-core Ryzen chip that replaces older NUC-class machines without effort and a build that runs cool even under sustained use, though more than one describes slow support when a port failed despite the three-year warranty. GMKtec NucBox G3 Pro (16GB + 512GB) owners like that its 16GB ships as two upgradeable DDR4 modules and that a second M.2 bay sits free, but flag a fan that gets loud under load, a lack of any USB-C port, and a handful of early hardware faults.
