2026 verdict
Pentium Gold versus a 12-core Radeon 680M is not a close fight, and the GMKtec NucBox M7 Ultra (32GB + 512GB) is the mini PC that wins.
It leads on DDR5 versus DDR4, 32GB versus 8GB, and 512GB versus 256GB, with dual 2.5G Ethernet and two USB4 ports behind a Ryzen 7 PRO 6850U. The Geekom Mini Air12 (Pentium 7505 8GB + 256GB) is cheaper and the one with a 3 year warranty, which is the honest case for a VESA-mounted kiosk. Buy the M7 Ultra as a real desktop; buy the Mini Air12 when the workload is a browser and the coverage period matters more than cores.
