Beelink SER3 (16GB + 500GB) vs GMKtec NucBox G3S (8GB + 256GB)

The Beelink SER3 (16GB + 500GB) wins overall, with double the memory, double the storage, a higher owner rating and a three-year warranty against one year. The GMKtec NucBox G3S (8GB + 256GB) only wins on price.

On core count, yes. The GMKtec NucBox G3S (8GB + 256GB) uses a four-core Intel N95, while the Beelink SER3 (16GB + 500GB) uses a two-core, four-thread AMD Ryzen 3 3200U. In practice both are entry-level chips suited to browsing and office work rather than heavy tasks, so the gap is smaller than the core counts suggest.

Memory and storage headroom. The Beelink SER3 (16GB + 500GB) ships with 16GB of DDR4 and a 500GB SSD, both double what the GMKtec NucBox G3S (8GB + 256GB) offers, and both machines have upgradeable SODIMM memory slots.

Both are built for low-power, always-on use, with owners of each describing them as near silent. Neither is designed for sustained heavy workloads, so the choice comes down to how much memory and storage the task needs rather than noise.

Buyers who want the absolute lowest price for a basic Windows desktop should choose the GMKtec NucBox G3S (8GB + 256GB).

Buyers who want more memory and storage out of the box, plus a longer warranty, for a modest step up in price should choose the Beelink SER3 (16GB + 500GB).
