Professional Workstation Tower

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D modeling, rendering and engineering workloads. It ships with an AMD Ryzen Threadripper PRO 3945WX processor running at 4.0 GHz base frequency with 12 cores and 24 threads. Thirty-two gigabytes of DDR4 ECC memory are installed across eight DIMM slots, leaving room for expansion up to 1 TB. Windows 11 Pro provides the operating environment.

Storage Interface and Expansion Limits

The system includes two built-in PCIe Gen 4 NVMe M.2 slots for high-speed solid-state drives. A 2 TB NVMe drive occupies one slot, while a 12 TB 7200 rpm hard drive adds bulk capacity. Additional PCIe Gen 4 expansion cards can add further GPU, networking or NVMe storage, but the total number of lanes and slots is fixed by the platform. Buyers who need more than two native M.2 devices must add a compatible add-in card.

Build Quality and Daily Connectivity

The 1000 W power supply supports the installed RTX A2000 graphics card and leaves headroom for future add-in cards or storage upgrades. Tower form factor allows tool-less access to drive bays, memory slots and expansion bays for routine maintenance. Front and rear I/O ports are positioned for permanent desk placement rather than frequent transport. Buyers who need a compact or mobile chassis should consider a different form factor.

Questions about this item

Should I pick the 2TB NVMe or the 12TB HDD for my active projects?

Use the 2TB NVMe drive for the operating system, applications and current project files; the 12TB 7200rpm HDD is best for archived data, large media libraries and backups.

What does the 4.0GHz base clock on the Threadripper 3945WX mean for daily rendering?

The 12-core processor runs at 4.0GHz base and can boost to 4.30GHz, giving consistent multi-threaded throughput for CPU rendering and simulation workloads.

Does the PCIe Gen 4 NVMe slot limit the 2TB drive's speed in this workstation?

The onboard PCIe Gen 4 M.2 slots support the 2TB NVMe drive at full interface speed, so the SSD is not bottlenecked by the slot.
