What the differences mean

Memory type and speed

The GMKtec K17 Plus runs LPDDR5X at 8533 MT/s while the Beelink SER9 Max uses DDR5-5600 in removable SO-DIMM slots. Faster memory helps the K17 Plus in memory-bound work, but it is soldered, so the configuration you buy is the one you keep.

Memory capacity and upgrades

The GMKtec K17 Plus ships with 32GB and tops out there, because its memory is soldered. The Beelink SER9 Max starts at 64GB and takes 128GB across two SO-DIMM slots, which matters if you expect to grow into virtual machines or a large photo library later.

Processor and graphics

The Beelink SER9 Max pairs an eight-core Ryzen 7 H 255 with Radeon 780M graphics, while the GMKtec K17 Plus uses Intel's Core Ultra 7 258V with Arc 140V and a 47 TOPS NPU. The K17 Plus is the newer platform and the better pick for on-device AI; the Ryzen has more threads for heavy multitasking.

Networking

One 10 Gigabit Ethernet port on the Beelink SER9 Max is four times the bandwidth of the 2.5G port on the GMKtec K17 Plus. On a fast home network or a NAS, the SER9 Max moves large files far quicker; on ordinary broadband the difference rarely shows.

Warranty and portability

Beelink backs the SER9 Max for three years against the one year on the GMKtec K17 Plus. The K17 Plus counters with a lighter 460g metal chassis, a VESA mount in the box and a Kensington lock slot, while the SER9 Max weighs 780g and includes none of those.

Thunderbolt support

The Beelink SER9 Max's USB4 port is listed as Thunderbolt 3 compatible, so it drives certified Thunderbolt docks and external enclosures. The GMKtec K17 Plus offers USB4 at 40Gbps but no Thunderbolt certification, so some Thunderbolt-only accessories will not work as intended.

  • you run local AI models and want a dedicated NPU
