What the differences mean

Graphics

The Geekom A9 Mega (64GB + 1TB) uses Radeon 8060S graphics, the top Strix Halo configuration, which behaves closer to a discrete card than a typical integrated GPU. The GMKtec NucBox M5 Ultra (32GB + 512GB) uses 8-core Radeon graphics built for display output and light games.

Memory

The Geekom A9 Mega (64GB + 1TB) has 64GB of LPDDR5X at 7500 MT/s soldered and shared with the GPU, which is permanent. The GMKtec NucBox M5 Ultra (32GB + 512GB) has 32GB of DDR4-3200 that can be upgraded to 64GB, a different trade between bandwidth and flexibility.

Storage

The Geekom A9 Mega (64GB + 1TB) ships a 1TB PCIe Gen 4 drive with RAID 0 and RAID 1 support. The GMKtec NucBox M5 Ultra (32GB + 512GB) ships 512GB across two M.2 2280 PCIe 3.0 slots, both replaceable.

Warranty

The Geekom A9 Mega (64GB + 1TB) carries a three-year warranty. The GMKtec NucBox M5 Ultra (32GB + 512GB) carries one year, which is short for a machine meant to run services around the clock.

Which one to buy if

What owners say

GMKtec NucBox M5 Ultra (32GB + 512GB) owners describe a machine that does far more than its price suggests. The dual 2.5 Gb Ethernet ports, the 8-core Ryzen 7 and the two M.2 slots come up constantly from people running Proxmox, Kubernetes, pfSense or a Linux desktop, and several report clean Fedora or Mint installs. Silence and size get equal billing, along with the fact that both memory and storage can be upgraded later. The complaints are specific: DDR4 and PCIe 3.0 rather than the newer standards, integrated graphics that run hot under sustained gaming, no USB4 or SD slot, a one-year warranty, and one owner who hit a sleep-wake bug and disabled sleep.
