Asus Chromebox 5a (Celeron 4GB + 128GB) vs Geekom A7 Max (Ryzen 9)

Full Mini PCs comparison in 2026

Updated November 2026
Data from the official Asus and Geekom sites.
2026 verdict
Choosing between a ChromeOS browser appliance and a full Windows workstation, Geekom A7 Max (Ryzen 9) is the far more capable mini PC, pairing DDR5 memory expandable to 64GB with a 1TB PCIe 4.0 drive that leaves the Asus Chromebox 5a (Celeron 4GB + 128GB) and its 4GB of single-channel DDR4 and 128GB drive well behind. The A7 Max also adds an eight-core Ryzen 9 7940HS, two 40Gbps USB4 ports, dual 2.5G Ethernet and a Kensington lock, all wrapped in an aluminium chassis with a VESA mount and HDMI cable included. The Chromebox answers back with ChromeOS itself: near-instant boot, automatic updates and Google admin console management, plus seven USB ports and four display outputs including DisplayPort, at a lower price point and in a package well suited to classrooms, kiosks and signage. Anyone who needs Windows software, heavier multitasking or room to grow storage and memory should pick the Geekom A7 Max (Ryzen 9); anyone managing a fleet of simple browser terminals should stick with the Asus Chromebox 5a (Celeron 4GB + 128GB).
