Lenovo ThinkStation P520 Workstation vs Lenovo ThinkStation P3 Tiny Workstation Desktop — Head-to-Head (2026)

Our verdict first, then the specs side by side.

Our verdict

Lenovo ThinkStation P3 Tiny Workstation Desktop is our pick.

For nearly any 2026 professional workload, the ThinkStation P3 Tiny wins because its 20-core Core i7-14700 (28 threads, 5.4 GHz boost) annihilates the P520's 4-core Xeon W-2123 (8 threads, 3.6 GHz), and its Turing-era T400 GPU is two generations newer than the P520's 2016 Maxwell Quadro M2000 — but the P520 remains the better buy if you need its 128 GB of RAM and tower expandability for memory-heavy work.
