What the differences mean

CPU cores

The Beelink SER5 Pro (16GB + 480GB) runs a six-core, twelve-thread Ryzen 5 5500U. The GMKtec NucBox G3 Pro (16GB + 512GB) runs a two-core, four-thread Intel Core i3-10110U, noticeably lighter for anything that multitasks.

Display outputs

The Beelink SER5 Pro (16GB + 480GB) drives three screens through HDMI, DisplayPort and USB-C. The GMKtec NucBox G3 Pro (16GB + 512GB) has two HDMI 1.4 ports only, which limits dual 4K to 24Hz.

Memory speed

Both ship 16GB of DDR4 in two slots with a 64GB ceiling, but the Beelink SER5 Pro (16GB + 480GB) runs it at 3200 MT/s against 2666 MHz on the GMKtec NucBox G3 Pro (16GB + 512GB).

Storage

512GB against 480GB is not a real difference on its own, but the GMKtec NucBox G3 Pro (16GB + 512GB) has a second, free M.2 2242 SATA slot the Beelink SER5 Pro (16GB + 480GB) does not, so it can grow without removing the original drive.

Price

The Beelink SER5 Pro (16GB + 480GB) is typically the lower priced of the two, on top of its faster memory and better display output.

Which one to buy if

What owners say

GMKtec NucBox G3 Pro (16GB + 512GB) owners describe it as fast to set up and comfortable for Word, Excel, browsing and 4K streaming, and many are surprised the memory is not soldered, since 16GB ships as two 8GB modules in dual-channel and the tool-free lid opens onto a second M.2 slot for more storage. A second group runs it headless as a Home Assistant or Linux server and reports it stable for months. The recurring complaint is the fan, rated below 38dB on paper but described as audible to loud once the box is pushed, and a few report no USB-C at all, a long first round of Windows updates and the odd early failure, from a dead HDMI output to a faulty Bluetooth radio.

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.
