Both ship the same 16GB of dual-channel DDR4 (64GB ceiling) and the same 512GB drive, and both keep a free second storage slot, but the A5 Pro answers back with a newer six-core Ryzen 5 7430U against the G3 Pro's older four-core Core i3-10110U, a three-year warranty against one year, and an SD card reader the G3 Pro skips. Owners of both report an easy setup and steady daily use, though G3 Pro buyers single out audible fan noise under load and no USB-C at all, while A5 Pro owners flag a storage layout with no 2.5 inch bay as the thing that catches people out. Pick the GMKtec NucBox G3 Pro for the lowest sticker price; pick the Geekom A5 Pro for a newer processor, an SD reader and the longer warranty.

What the differences mean

Processor generation

The A5 Pro runs a six-core, twelve-thread AMD Ryzen 5 7430U at up to 4.5 GHz. The G3 Pro runs an older four-core Intel Core i3-10110U. Owners of both describe the machines as fast enough for office work, but the A5 Pro is the newer chip by several years.

Warranty

The A5 Pro carries a three-year warranty; the G3 Pro carries one year. For a budget box meant to run for years, that gap in coverage is worth weighing against the price difference.

Ports

The G3 Pro has no USB-C, DisplayPort, Thunderbolt or USB4 at all, only four USB-A ports and two HDMI 1.4 outputs (dual 4K limited to 24Hz). The A5 Pro adds two USB-C 3.2 Gen 2 ports with DisplayPort output and dual HDMI 2.0, for four displays total against the G3 Pro's two.

SD card slot

Only the A5 Pro has one, useful for offloading camera media without an adapter. The G3 Pro has neither an SD reader nor, per its own reviews, much documentation to explain the gap.

Which one to buy if

  • the lowest possible price is what matters most
    GMKtec NucBox G3 Pro (16GB + 512GB)

    The GMKtec NucBox G3 Pro undercuts the Geekom A5 Pro on price while shipping the same memory and storage.

  • you want a newer processor and do not want to hear the fan
    Geekom A5 Pro (Ryzen 5 16GB + 512GB)

    The A5 Pro's six-core Ryzen 5 7430U is a newer chip, and its owners do not report the fan noise G3 Pro owners consistently flag under load.

  • the desk needs more than two displays or any USB-C port
    Geekom A5 Pro (Ryzen 5 16GB + 512GB)

    The G3 Pro has no USB-C, DisplayPort or USB4 of any kind; the A5 Pro adds two USB-C ports and drives up to four screens.

  • you photograph often and want a built-in card reader
    Geekom A5 Pro (Ryzen 5 16GB + 512GB)

    Only the A5 Pro has an SD card slot; the G3 Pro has none.

  • the machine will run Home Assistant or a small home server headless
    GMKtec NucBox G3 Pro (16GB + 512GB)

    The G3 Pro's dual-channel memory, free M.2 slot and 2.5 Gigabit Ethernet suit that role well, and its owners already run it that way, at the lower price.

What owners say

Owners of both machines agree on the basics: setup is fast, Windows 11 Pro arrives clean with no trial software, and daily office work, browsing and streaming feel comfortably fast for a budget box. Beyond that they diverge. GMKtec NucBox G3 Pro (16GB + 512GB) owners praise how upgradeable it feels for the price, confirming the memory is not soldered and the tool-free lid gives easy access to a second M.2 slot, but they consistently flag the fan as audible under load and note there is no USB-C anywhere on the unit, only Type-A ports. Geekom A5 Pro (Ryzen 5 16GB + 512GB) owners praise a quiet all-aluminium chassis solid enough that one buyer ordered a second unit for the office, but their complaint runs the other way: expecting a 2.5 inch drive bay like the standard A5, several discovered the A5 Pro dropped it in favor of M.2-only storage.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
