2026 verdict
These two Beelink boxes score almost identically, and the cheaper one wins: the Beelink SER9 Max (64GB + 1TB) edges the Beelink GTi15 Ultra (64GB + 1TB) on price alone.
The pair tie on 64GB of DDR5-5600, a 1TB drive and a three-year warranty, so the Beelink SER9 Max's lower price is what decides it, helped by its Ryzen 7 H 255 and Radeon 780M graphics. The Beelink GTi15 Ultra costs more but brings features the compared rows do not score: a second 10 Gigabit Ethernet port, an internal 145W power supply, a PCIe 5.0 x8 slot for a desktop GPU dock and an SD card reader. Buy the Beelink SER9 Max for the same core platform at the lower price; buy the Beelink GTi15 Ultra if dual 10GbE, an internal power supply and a future graphics upgrade are worth the premium.

What the differences mean
Networking
The Beelink GTi15 Ultra has two 10 Gigabit Ethernet ports, where the Beelink SER9 Max has one. A second 10GbE link is useful for a router, a NAS or link aggregation, though a single 10G port already saturates most home networks.
Power supply
The Beelink GTi15 Ultra builds a 145W power supply into the chassis, so it runs from a single cord. The Beelink SER9 Max uses an external 100W adapter, which means a brick on the desk or floor.
Graphics expansion
The Beelink GTi15 Ultra carries a PCIe 5.0 x8 slot for Beelink's external GPU dock, so it can later drive a desktop graphics card. The Beelink SER9 Max relies on its integrated Radeon 780M and a Thunderbolt 3-compatible USB4 port instead.
Processor and graphics
The Beelink SER9 Max uses an eight-core Ryzen 7 H 255 with Radeon 780M graphics, while the Beelink GTi15 Ultra runs a 16-core Intel Core Ultra 9 285H with Arc 140T and an NPU. The compared rows call the CPUs and GPUs neutral, so pick on platform preference rather than a clear spec win.
Audio and extras
The Beelink GTi15 Ultra includes speakers, a microphone array, an SD 4.0 card reader and a fingerprint sensor. The Beelink SER9 Max has none of those, so calls and card imports need external hardware on the cheaper machine.
Size and price
The Beelink SER9 Max is the smaller and lighter of the two at 135mm square and 780g, while the Beelink GTi15 Ultra measures about 158mm. The SER9 Max is also the more affordable option, which is the one row that decides this matchup.
