2026 verdict
Between the dual-core Beelink SER3 (16GB + 500GB) and the quad-core, eight-thread GMKtec NucBox M2 Pro S (16GB + 1TB), the extra cores make the GMKtec the stronger buy for real multitasking, not just browsing.

It also runs faster memory and doubles the SER3's storage to a full terabyte spread across two M.2 bays. The Beelink SER3 (16GB + 500GB) answers with a lower price and a three-year warranty against the GMKtec's one year, and it remains a fine choice for browsing, office documents and 4K playback. Buyers who run several demanding programs at once, or want more storage and a third display, should pick the GMKtec NucBox M2 Pro S (16GB + 1TB); anyone on a tight budget whose needs are modest, and who values the longer warranty, should stick with the Beelink SER3 (16GB + 500GB).

What the differences mean

Processor cores

The Beelink SER3 (16GB + 500GB) runs a dual-core, four-thread Ryzen 3 3200U, while the GMKtec NucBox M2 Pro S (16GB + 1TB) runs a four-core, eight-thread Core i7-1185G7. That difference shows up the moment several programs or a heavy batch of browser tabs run together, not in ordinary single-task browsing.

Storage capacity and layout

500GB on a single M.2 bay against 1TB spread across a PCIe 4.0 NVMe slot plus a second M.2 2242 SATA slot on the GMKtec. Both drives can be swapped later, but the GMKtec starts with double the room and a second bay to grow into.

Display output

The Beelink SER3 drives two screens over its dual HDMI ports. The GMKtec NucBox M2 Pro S adds a USB-C port carrying DisplayPort video, so it manages three 4K 60Hz displays without a dock.

Warranty

Three years on the Beelink SER3 (16GB + 500GB) against one year on the GMKtec NucBox M2 Pro S (16GB + 1TB), which matters more on a machine bought to last than on one bought purely to save money today.

Which one to buy if

What owners say

Beelink SER3 (16GB + 500GB) owners report a machine that keeps earning its keep well past the return window: several describe it still running fine after a year, one after nearly five years of light daily use, and many single out how quiet and cool it stays tucked behind a TV or a monitor. The accessible DDR4 slots and a genuinely licensed Windows 11 Pro also come up often as reasons it feels like more computer than the price suggests. The complaints cluster just as tightly: a minority report spontaneous reboots or crashes within the first couple of months, and more than one owner wishes the dual-core processor had another core or two for heavier multitasking, since it visibly slows down once several demanding programs run at once.

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.
