Geekom A9 Max (HX 470) vs GMKtec NucBox G3S (8GB + 256GB)

The Geekom A9 Max (HX 470) is the stronger machine overall, with a higher rating, a longer warranty, DDR5 memory against DDR4, four times the RAM and about eight times the storage of the GMKtec NucBox G3S (8GB + 256GB). The NucBox G3S wins on price and remains a sensible pick for buyers who only need a basic Windows desktop.

The platform generation. The Geekom A9 Max (HX 470) runs an AMD Ryzen AI 9 HX 470 with an XDNA 2 NPU and Radeon 890M graphics, backed by 32GB of DDR5 memory and 2TB of NVMe storage. The GMKtec NucBox G3S (8GB + 256GB) uses a much lighter Intel Processor N95 with no NPU, 8GB of DDR4 memory and a 256GB SSD, aimed at basic desktop tasks rather than demanding workloads.

Only the Geekom A9 Max (HX 470) does. Its Ryzen AI 9 HX 470 includes an XDNA 2 NPU rated at 50 TOPS on its own, enough for Copilot+ style features and running local language models. The GMKtec NucBox G3S (8GB + 256GB) has no NPU, so on-device AI acceleration is not available on that machine.

The Geekom A9 Max (HX 470) has far more headroom, with DDR5 memory expandable to 128GB across dual-channel SODIMM slots and two NVMe slots supporting up to 8TB combined. The GMKtec NucBox G3S (8GB + 256GB) is capped at 16GB of DDR4 in its single memory slot, though it does offer two M.2 slots of its own for extra storage.

Buyers doing local AI work, 8K-capable video editing, multi-display workstation setups or anyone who wants a mini PC they will not outgrow for years should choose the Geekom A9 Max (HX 470). Its NPU, DDR5 memory and dual NVMe storage justify the higher position in the lineup.

Buyers who need a quiet, inexpensive Windows desktop for browsing, streaming, office work or a home theatre box should choose the GMKtec NucBox G3S (8GB + 256GB). It covers those everyday tasks well and includes a VESA mount and HDMI cable, though its single memory slot and 256GB SSD leave little room to grow into heavier workloads.
