Geekom A5 Pro (Ryzen 5 16GB + 512GB) vs GMKtec NucBox G3 Pro (16GB + 512GB)

Full Mini PCs comparison in 2026

Data from Amazon and official Geekom and GMKtec sites.
2026 verdict
Price is the deciding factor in this mini PC matchup, and it puts the GMKtec NucBox G3 Pro (16GB + 512GB) ahead of the Geekom A5 Pro (Ryzen 5 16GB + 512GB) on the one spec most shoppers weigh first.
The Geekom A5 Pro counters with a longer warranty, a more modern six-core AMD Ryzen 5 7430U, and a chassis extra the G3 Pro skips, an SD card slot. Both ship with 16GB of dual-channel DDR4 that maxes out at 64GB, a 512GB M.2 SSD, 2.5G Ethernet, Wi-Fi 6 and Windows 11 Pro, so the two land close together once you get past the CPU generation gap. The G3 Pro's Core i3-10110U trades some raw processing headroom for a genuinely dual-drive storage layout, since its second M.2 SATA bay sits empty and ready, something the A5 Pro's single M.2 slot cannot match. Buyers who want the lowest sticker price and room to add a second drive later should pick the GMKtec NucBox G3 Pro, while anyone who values a newer processor, an SD reader and a longer warranty should choose the Geekom A5 Pro.

Frequently Asked Questions

Which is better overall: Geekom A5 Pro (Ryzen 5 16GB + 512GB) or GMKtec NucBox G3 Pro (16GB + 512GB)?

The GMKtec NucBox G3 Pro (16GB + 512GB) edges ahead in this comparison on price, the one category where the two differ meaningfully. The Geekom A5 Pro (Ryzen 5 16GB + 512GB) wins on warranty length, so the better fit depends on whether budget or coverage matters more.

What is the biggest difference between the Geekom A5 Pro and the GMKtec NucBox G3 Pro?

Processor platform and warranty. The Geekom A5 Pro runs a newer six-core AMD Ryzen 5 7430U and includes a three-year warranty, while the GMKtec NucBox G3 Pro runs an older four-core Intel Core i3-10110U with only a one-year warranty, but undercuts it on price.

Do both mini PCs have the same storage expansion options?

No. The G3 Pro pairs its main M.2 2280 PCIe 3.0 drive with a second, empty M.2 2242 SATA bay, so a second drive can be added without removing the first. The A5 Pro has a single M.2 2280 PCIe 3.0 slot and no separate 2.5 inch SATA bay, so expanding storage means swapping the drive it ships with.

Does either one have an SD card reader or a Kensington lock?

Only the Geekom A5 Pro has an SD card slot. Both machines include a Kensington lock slot on the rear panel, useful for a shared or open-plan office desk.

Who should buy the Geekom A5 Pro?

Buyers who want a newer six-core processor, an SD card reader, and the reassurance of a three-year warranty, and who are willing to pay a bit more for those extras.

Who should buy the GMKtec NucBox G3 Pro?

Budget-focused buyers who want the lowest entry price and a second free M.2 storage bay for future expansion, without needing the newest CPU.
