Lenovo ThinkStation P620 Threadripper PRO 3945WX 4.0GHz 192GB RTX 4000 2x2TB NVMe 2x12TB HDD W11 Pro

Threadripper PRO workstation for CAD and rendering

The Lenovo ThinkStation P620 is a tower workstation built around the AMD Ryzen Threadripper PRO 3945WX with 12 cores running at 4.0 GHz base and 4.30 GHz boost. It ships with 192 GB of DDR4 ECC memory across eight slots and an NVIDIA RTX 4000 graphics card. Storage combines 4 TB of NVMe SSD capacity and 24 TB of 7200 rpm HDD space. Windows 11 Pro is pre-installed for professional workflows.

Simple deployment with standard tower access

The tower chassis provides straightforward access to memory slots, drive bays and expansion cards for initial setup or later upgrades. A 1000 W power supply delivers headroom for the configured components and additional PCIe Gen 4 add-in cards. The only common friction point is the physical weight of a fully populated tower, which requires two people or a lift to position safely on a desk or rack shelf.

Suits engineers and studios needing large local

This configuration fits professionals who keep active projects, simulations and asset libraries on local storage without relying on network shares. The 192 GB memory ceiling and eight-channel architecture support large assemblies and virtual machines. Buyers who need more than 1 TB of total RAM or who require a smaller form factor for space-constrained offices should evaluate alternative platforms.
