It gives you 32 GB of upgradeable DDR4 as standard, two 2.5G Ethernet ports and Windows 11 Pro, all for less than the Apple, and its eight-core Ryzen 7 7730U handles office work, Linux and light gaming. The Apple Mac Mini (M4 16GB + 512GB) is the faster and quieter machine, with the 10-core M4, 16 GB of unified memory, three Thunderbolt 4 ports and a premium aluminium build, but neither its memory nor its storage can ever be changed. Choose the GMKtec NucBox M5 Ultra (32GB + 512GB) if you want Windows, more memory and fast wired networking, and the Apple Mac Mini (M4 16GB + 512GB) if you want the fastest, most power-efficient desktop and work inside macOS.

What the differences mean

Memory

The GMKtec NucBox M5 Ultra (32GB + 512GB) ships 32 GB of DDR4 across two SO-DIMM slots and takes 64 GB. The Apple Mac Mini (M4 16GB + 512GB) has 16 GB of unified memory soldered to the chip, fixed for life. The GMKtec offers more capacity and a path to add more; the Apple's memory is faster but cannot grow.

Wired networking

The GMKtec NucBox M5 Ultra (32GB + 512GB) has two 2.5G Ethernet ports, while the Apple Mac Mini (M4 16GB + 512GB) has a single Gigabit port. For moving files to a NAS or running a network service, the GMKtec is roughly two and a half times faster on each link and can separate two networks.

Ports

The Apple Mac Mini (M4 16GB + 512GB) leads here with three Thunderbolt 4 ports, HDMI and two front USB-C ports. The GMKtec NucBox M5 Ultra (32GB + 512GB) has HDMI, DisplayPort and USB-C but no Thunderbolt. The Apple is the better dock-and-display hub; the GMKtec needs no hub for a wired network.

Operating system

The GMKtec NucBox M5 Ultra (32GB + 512GB) ships with Windows 11 Pro and runs Linux cleanly, so Windows-only software and virtualisation are straightforward. The Apple Mac Mini (M4 16GB + 512GB) runs macOS, which suits creative and Apple-first workflows but cannot run Windows software natively.

Power and efficiency

The Apple Mac Mini (M4 16GB + 512GB) has an internal power supply and an efficient M4, so no brick sits on the desk and it draws very little. The GMKtec NucBox M5 Ultra (32GB + 512GB) uses an external adapter. The Apple is the tidier, more efficient machine; the GMKtec is the more expandable one.

Which one to buy if

What owners say

The two groups are happy for different reasons. GMKtec NucBox M5 Ultra (32GB + 512GB) owners open with performance per watt, surprised how much the Ryzen 7 does for how little power it draws, then praise the silence and clean Linux installs of Fedora and Mint. They report GMKtec support as quick and helpful, and their complaints are the older DDR4 and PCIe 3.0 platform, graphics that run hot under gaming, and a rare sleep-wake fault. Apple Mac Mini (M4 16GB + 512GB) owners talk about speed and size: apps launch instantly, the machine stays whisper quiet under load and it is far smaller than expected, with several replacing iMacs or Windows towers. Their warnings are that memory and storage are soldered and fixed at purchase, that they often add an external drive or a hub, and that the power button sits awkwardly underneath.

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.
