2026 verdict

Winner

$559.99

Six Ryzen cores against eight, and 16GB against 32GB: the GMKtec NucBox M5 Ultra (32GB + 512GB) wins on both memory and storage capacity over the Beelink SER5 Pro (16GB + 480GB), which in turn keeps the lower price and a higher owner rating. The Beelink SER5 Pro (16GB + 480GB) also drives three displays through HDMI, DisplayPort and USB-C, a genuine strength for a budget machine, while the GMKtec NucBox M5 Ultra (32GB + 512GB) sticks to two outputs but adds a second network port. Both use previous-generation AMD mobile processors and DDR4 memory, so raw CPU performance is closer than the memory gap suggests. Choose the GMKtec NucBox M5 Ultra (32GB + 512GB) for more memory and storage; choose the Beelink SER5 Pro (16GB + 480GB) for a lower price and triple-monitor support.
