Buy on Amazon USA
A 16-core Core Ultra 9 285H with Arc 140T graphics, 64GB of dual-channel DDR5-5600, two 10 Gigabit Ethernet ports and an internal 145W power supply put it in a different class from the GMKtec NucBox M2 Pro S (16GB + 1TB), which answers on price with an 11th Gen Core i7 and DDR4-3200. Pick the GTi15 Ultra for a fast-network desktop that might gain a GPU later, and the M2 Pro S for low-cost office work behind a monitor.

What the differences mean

Memory

The Beelink GTi15 Ultra ships with 64GB of DDR5-5600 in dual channel and takes 128GB, while the GMKtec NucBox M2 Pro S carries 16GB of DDR4-3200 with a 64GB ceiling. Four times the memory and a newer, faster type is the largest gap between these machines.

Networking

The Beelink GTi15 Ultra has two 10 Gigabit Ethernet ports and Wi-Fi 7; the GMKtec NucBox M2 Pro S has a single 2.5G port and Wi-Fi 6. For a NAS, a homelab or large file transfers, only the Beelink can saturate a fast wired network.

Expandability

The Beelink GTi15 Ultra runs two M.2 2280 PCIe 4.0 slots and, more unusually, a PCIe 5.0 x8 slot for a desktop graphics card through Beelink's dock. The GMKtec NucBox M2 Pro S offers an M.2 2280 bay plus a slower 2242 SATA bay and no graphics path.

Audio and inputs

Only the Beelink GTi15 Ultra has built-in speakers, a microphone array and a fingerprint sensor built into the power button. The GMKtec NucBox M2 Pro S has none of those, so calls need a headset or a monitor with speakers.

Power and warranty

The Beelink GTi15 Ultra hides a 145W supply inside the case and carries a three-year warranty; the GMKtec NucBox M2 Pro S uses an external 100W brick and a one-year term. The Beelink needs a single cable and is covered for longer.

Which one to buy if

  • you run a NAS, homelab or 10 Gigabit network
    Beelink GTi15 Ultra (64GB + 1TB)

    Two 10 Gigabit ports and Wi-Fi 7 on the Beelink GTi15 Ultra move far more data than the single 2.5G link on the GMKtec NucBox M2 Pro S.

  • you want to add a desktop graphics card later
    Beelink GTi15 Ultra (64GB + 1TB)

    Only the Beelink GTi15 Ultra has the PCIe 5.0 x8 slot and Beelink's dock option for a real GPU.

  • the machine is a cheap browser and office box
    GMKtec NucBox M2 Pro S (16GB + 1TB)

    The GMKtec NucBox M2 Pro S keeps the 1TB drive, triple 4K output and dual memory slots at a fraction of the cost.

  • you need the smallest, lightest desktop of the two
    GMKtec NucBox M2 Pro S (16GB + 1TB)

    At 114 x 106 x 42.5 mm and 361g, the GMKtec NucBox M2 Pro S hides behind a monitor where the 158 mm Beelink may not.

Price history compared
