2026 verdict
Two compact machines made for a quiet desk, and the Beelink SER9 Pro (24GB + 1TB) edges this one.
It wins on the better owner rating, on a three-year warranty, on memory bandwidth with LPDDR5X at 6400 MT/s and on the stronger Radeon 780M inside its Ryzen 7 H 255. The GMKtec NucBox M6 Ultra (32GB + 1TB) counters with more memory that can be upgraded to 128GB, dual 2.5G Ethernet for a firewall or home lab, Wi-Fi 6E and a lower price, against DDR5-4800, PCIe 3.0 drive bays and a one-year warranty. Both include USB4 and two M.2 slots. Pick the Beelink SER9 Pro (24GB + 1TB) for the faster memory, the better graphics and the longer cover, and the GMKtec NucBox M6 Ultra (32GB + 1TB) for two wired networks and room to grow.

What the differences mean
Processor and graphics
The Beelink SER9 Pro (24GB + 1TB) uses an eight-core Ryzen 7 H 255 with a Radeon 780M, a step above the six-core Ryzen 5 7640HS and Radeon 760M in the GMKtec NucBox M6 Ultra (32GB + 1TB), which shows most in gaming and graphics work.
Memory
The Beelink SER9 Pro (24GB + 1TB) has 24GB of soldered LPDDR5X at 6400 MT/s, while the GMKtec NucBox M6 Ultra (32GB + 1TB) has 32GB of DDR5 at 4800 MT/s in two slots that reach 128GB, so the GMKtec offers more capacity but slower memory.
Networking
The GMKtec NucBox M6 Ultra (32GB + 1TB) has two 2.5G Ethernet ports, enough to run a firewall or a dual-network home lab. The Beelink SER9 Pro (24GB + 1TB) has a single 2.5G port.
Warranty
The Beelink SER9 Pro (24GB + 1TB) is backed for three years; the GMKtec NucBox M6 Ultra (32GB + 1TB) for one.
Storage bays
Both offer two M.2 2280 slots, but the Beelink SER9 Pro (24GB + 1TB) runs them at PCIe 4.0 for faster drives, while the GMKtec NucBox M6 Ultra (32GB + 1TB) uses PCIe 3.0.
Which one to buy if
- you want the stronger integrated graphics and faster memory
The Beelink SER9 Pro (24GB + 1TB) pairs a Radeon 780M with LPDDR5X at 6400 MT/s.
- you need two wired networks for a firewall or home lab
The GMKtec NucBox M6 Ultra (32GB + 1TB) is the one with dual 2.5G Ethernet.
- you want to add memory later
The GMKtec NucBox M6 Ultra (32GB + 1TB) reaches 128GB; the Beelink SER9 Pro (24GB + 1TB) is fixed at 24GB.
- you want the longer warranty
The Beelink SER9 Pro (24GB + 1TB) carries three years against one on the other.
- you want a compact multi-monitor desktop on a tighter budget
The GMKtec NucBox M6 Ultra (32GB + 1TB) costs less and still drives three displays over HDMI, DisplayPort and USB4.

What owners say
What GMKtec NucBox M6 Ultra (32GB + 1TB) owners emphasise is how much arrives already installed: 32GB of dual-channel DDR5, a 1TB drive, a second free M.2 slot and two 2.5G network ports, all in a box small enough to hide behind a monitor. The three selectable power modes get used to trade noise for speed, and home-lab owners report it handling Proxmox and media transcoding, while light and retro gaming runs better than the integrated graphics usually allow. Against that, some report fan noise that needs a Windows power tweak, a pattern of units failing early, support that blamed other components before the PC, and a warranty that lasts only a year.
