Lenovo PCSP P520 Workstation vs GMKtec Mini PC Workstation — Head-to-Head (2026)

Our verdict first, then the specs side by side.

Our verdict

Lenovo PCSP P520 Workstation is our pick.

For almost any 2026 buyer, the GMKtec K10 mini PC wins: its 14-core/20-thread i9-13900HK and DDR5-5600 memory crush the Lenovo P520's 4-core/8-thread Xeon W-2123 (2017) and DDR4-2133, while drawing 45W instead of feeding a 900W tower. The P520 only makes sense if you specifically need its discrete-GPU slot, PCIe expansion, or ECC RDIMM headroom to 512GB.

Buy the GMKtec K10 if you want the fastest CPU-bound desktop performance per watt and dollar in a tiny, modern (2025) box with DDR5, 2.5GbE, and 8K DisplayPort output. Buy the Lenovo P520 only if you need a full-height PCIe slot for a discrete GPU, ECC registered memory expansion to 512GB, or internal 3.5" drive bays that a mini PC physically can't provide.
