Geekom A5 Pro 2026 Edition (16GB + 1TB) vs GMKtec NucBox G3S (8GB + 256GB)

The Geekom A5 Pro 2026 Edition (16GB + 1TB) comes out ahead, with double the memory, four times the storage and a three-year warranty against the GMKtec NucBox G3S (8GB + 256GB)'s one-year coverage. The NucBox G3S wins on price and remains the better fit for a single-screen budget desktop.

Display support and storage headroom. The Geekom A5 Pro 2026 Edition (16GB + 1TB) drives up to four monitors through two HDMI 2.0 ports and two USB-C DisplayPort outputs, plus a 1TB SSD, while the GMKtec NucBox G3S (8GB + 256GB) is limited to two HDMI outputs and a 256GB SSD, aimed at a simpler single or dual-monitor desk.

The Geekom A5 Pro 2026 Edition (16GB + 1TB) uses an AMD Ryzen 5 7530U with Radeon Vega 7 graphics, a six-core chip built for office multitasking. The GMKtec NucBox G3S (8GB + 256GB) uses a lighter four-core Intel Processor N95 with Intel UHD graphics, suited to browsing, streaming and basic productivity rather than heavier multitasking.

The Geekom A5 Pro 2026 Edition (16GB + 1TB) has 2.5G Ethernet, an SD card reader and a Kensington lock slot alongside six USB ports. The GMKtec NucBox G3S (8GB + 256GB) sticks to Gigabit Ethernet and has no SD card reader, though it still offers three USB 3.2 Type-A ports for peripherals.

Buyers setting up a multi-monitor office workstation, needing faster networking, or wanting more memory and storage headroom without opening the case again should choose the Geekom A5 Pro 2026 Edition (16GB + 1TB).

Buyers who want the least expensive way to put a real Windows desktop behind a monitor or TV, for browsing, streaming and light office work, should choose the GMKtec NucBox G3S (8GB + 256GB). Its smaller memory and storage are fine as long as the workload stays light.
