What the differences mean
Memory
The GMKtec NucBox M7 Ultra (32GB + 512GB) ships 32 GB of DDR5-4800 in two SODIMM slots that can reach 64 GB, while the Beelink SER9 Pro (24GB + 1TB) uses 24 GB of faster LPDDR5X-6400 soldered to the board. The GMKtec grows; the Beelink is fixed from day one.
Graphics
The Beelink SER9 Pro (24GB + 1TB) uses Radeon 780M graphics and the GMKtec NucBox M7 Ultra (32GB + 512GB) the older Radeon 680M. For light gaming and media, the newer silicon in the Beelink is the one to have.
External GPU
The GMKtec NucBox M7 Ultra (32GB + 512GB) has an OCuLink port that gives an external dock a native PCIe Gen4 x4 link, on top of its two USB4 ports. The Beelink SER9 Pro (24GB + 1TB) offers USB4 with Thunderbolt 3 compatibility but no OCuLink.
Storage and warranty
The Beelink SER9 Pro (24GB + 1TB) ships with twice the storage and three years of coverage against one on the GMKtec NucBox M7 Ultra (32GB + 512GB). Both leave a second M.2 bay free for expansion.
Networking and mounting
The GMKtec NucBox M7 Ultra (32GB + 512GB) brings dual 2.5G Ethernet, a Kensington lock and a VESA bracket in the box, where the Beelink SER9 Pro (24GB + 1TB) has a single 2.5G port, no lock slot and no VESA mount.
Cooling
Both are built to run quietly, the Beelink SER9 Pro (24GB + 1TB) with a vapor chamber rated near 32 decibels and the GMKtec NucBox M7 Ultra (32GB + 512GB) with its Hyper Ice Chamber. Neither is a machine you will notice under light load.
Which one to buy if
- you want to add an external GPU later
The M7 Ultra's OCuLink port carries a native PCIe Gen4 x4 link, with two USB4 ports as backup.
- you need the fastest memory and newer integrated graphics
LPDDR5X-6400 and Radeon 780M graphics are a step ahead of DDR5-4800 and the Radeon 680M.
- you want more memory and room to expand it
32 GB in two SODIMM slots reaching 64 GB beats 24 GB of soldered memory.
- you want more storage and a longer warranty out of the box
A 1 TB drive and three years of coverage come standard.
- you run a firewall or a dual-network setup
Dual 2.5G Ethernet ports are what separates a router box from a desktop.

What owners say
Owners of the GMKtec NucBox M7 Ultra (32GB + 512GB) lead with how quiet it stays: the dual-fan cooling runs quietly even while multitasking, and several pair the words quiet and fast. The front OCuLink port is the second theme, described as an upgrade path that avoids replacing the machine when a GPU or local models enter the picture, and owners like that the top cover comes off without tools to add a second drive. Their complaints are practical: a couple of units needed a fresh Windows key on first boot, one failed within months, and the one-year warranty is worth registering.
