What the differences mean

Processor and workload

The Geekom IT13 (2TB) runs an Intel Core i9-13900HK, a chip owners push through 4K editing, DAWs and local AI. The GMKtec NucBox G3 Pro (16GB + 512GB) uses a Core i3-10110U meant for documents, browsing and streaming, so it is not a creative workstation.

Memory

The Geekom IT13 (2TB) ships 32 GB of DDR4 at 3200 MT/s, while the GMKtec NucBox G3 Pro (16GB + 512GB) ships 16 GB at 2666 MHz. Both cap at 64 GB, but the Geekom starts with twice the memory and runs it faster.

Storage

The Geekom IT13 (2TB) includes a 2 TB PCIe 4.0 SSD plus an M.2 2242 SATA slot and a 2.5-inch bay for bulk drives. The GMKtec NucBox G3 Pro (16GB + 512GB) has 512 GB in one PCIe 3.0 slot and a free M.2 2242 SATA slot, far less room for large libraries.

Ports and displays

The Geekom IT13 (2TB) adds two USB4 ports, an SD card reader and a Kensington lock to its dual HDMI outputs, driving up to four displays. The GMKtec NucBox G3 Pro (16GB + 512GB) has no USB-C, DisplayPort or SD slot and limits dual 4K to 24 Hz on HDMI 1.4.

Price and warranty

The GMKtec NucBox G3 Pro (16GB + 512GB) is the more affordable of the two, but the Geekom IT13 (2TB) backs its higher price with a three-year warranty against one year.

Which one to buy if

What owners say

Owners of both machines describe them as small and quiet enough to sit on the desk or behind a monitor, and both groups value the Windows 11 Pro setup. Geekom IT13 (2TB) owners push theirs much harder, reporting 4K video editing, large RAW photo batches, professional audio work and always-on Plex duty while staying responsive, and they highlight the metal build and the three-year warranty. GMKtec NucBox G3 Pro (16GB + 512GB) owners talk about handling Word, Excel, browsers and streaming comfortably, about the easy upgrade to 64 GB and a second drive, and about the VESA kit. Their warnings differ too: IT13 owners find support inconsistent and the case warm under sustained load, while G3 Pro owners cite HDMI 1.4, the missing USB-C and a fan audible under load.
