2026 verdict
Hardware separates these two by a generation, and the Geekom A9 Max (HX 370) is the more modern mini PC of the pair.
It brings a Ryzen AI 9 HX 370 with a 50 TOPS NPU, 32 GB of DDR5 at 5600 MT/s against DDR4 at 2666 MHz, a 128 GB memory ceiling, a 1 TB drive with two Gen 4 slots, dual 2.5G Ethernet, Wi-Fi 7 and two USB4 ports. The GMKtec NucBox G3 Pro (16GB + 512GB) wins on price and on its owner rating, and it remains a tidy option for office work and light server duty with its 2.5 Gigabit port, dual-channel memory and free M.2 slot.

What the differences mean
Processor and AI
The Geekom A9 Max (HX 370) pairs twelve Zen 5 cores with a 50 TOPS NPU and Radeon 890M graphics. The GMKtec NucBox G3 Pro (16GB + 512GB) has a Core i3-10110U and integrated UHD graphics with no AI accelerator, so it cannot run local models or heavy creative work.
Memory
The Geekom A9 Max (HX 370) ships 32 GB of DDR5 at 5600 MT/s and takes up to 128 GB. The GMKtec NucBox G3 Pro (16GB + 512GB) ships 16 GB of DDR4 at 2666 MHz and stops at 64 GB.
Storage
The Geekom A9 Max (HX 370) starts at 1 TB with a second Gen 4 M.2 2230 slot free. The GMKtec NucBox G3 Pro (16GB + 512GB) has 512 GB in a PCIe 3.0 slot plus a free M.2 2242 SATA slot, which is slower and smaller.
Connectivity
The Geekom A9 Max (HX 370) offers dual 2.5G Ethernet, Wi-Fi 7, Bluetooth 5.4, two USB4 ports, two HDMI 2.1 FRL outputs and an SD 4.0 reader. The GMKtec NucBox G3 Pro (16GB + 512GB) has one 2.5 Gigabit port, Wi-Fi 6, no USB-C and only two HDMI 1.4 outputs.
Warranty against price
The GMKtec NucBox G3 Pro (16GB + 512GB) is the cheaper box and the better rated by owners, while the Geekom A9 Max (HX 370) adds a three-year warranty to its much higher price.

What owners say
GMKtec NucBox G3 Pro (16GB + 512GB) owners describe a tiny Windows desktop that is quick to set up and easy to work on later. They confirm the 16 GB runs as two modules in dual-channel, that the tool-free lid exposes a free M.2 2242 SATA slot, and that the 2.5 Gigabit port and four USB-A ports cover a normal desk. The repeated complaints are the absence of USB-C, DisplayPort and Thunderbolt, HDMI 1.4 holding dual 4K to 24 Hz, a fan that owners hear under load, and a few early failures or Bluetooth faults. Many still call it stable after months of daily use, and the included VESA plate is widely appreciated.
