ThinkStation P620 Threadripper PRO Workstation

The Lenovo ThinkStation P620 is a tower workstation built around the AMD Ryzen Threadripper PRO 3945WX processor with 12 cores running at 4.0 GHz base frequency. It ships with 64 GB of DDR4 ECC memory installed across eight DIMM slots, an NVIDIA Quadro P4000 graphics card, a 2 TB NVMe M.2 SSD and a 4 TB 7200 rpm HDD. Windows 11 Pro is pre-installed and the 1000 W power supply provides headroom for expansion cards and additional storage.

Suited for engineering.

This configuration fits professionals who need certified drivers for CAD, simulation and visualization software and who benefit from 8-channel memory bandwidth and PCIe Gen 4 expansion slots. Buyers who require more than 64 GB of active memory for massive assemblies or who need multiple high-end GPUs for GPU-only render farms should look at a different configuration.

12-core Threadripper PRO 3945WX at 4.0 GHz base

The single specification that decides fit is the processor: a 12-core, 24-thread Threadripper PRO 3945WX with a 4.0 GHz base clock and 4.30 GHz boost. If the workload scales across 12 cores and benefits from 8-channel DDR4 ECC bandwidth, this workstation matches the requirement; if the software is strictly single-threaded or demands higher core counts, another platform is appropriate.

Questions about this item

What physical space does the ThinkStation P620 tower need for the 7200rpm 4TB HDD?

The tower chassis accepts standard 3.5-inch drive bays; the 4TB HDD mounts in one of those bays using the supplied rails or screws.

How is the 2TB NVMe M.2 SSD installed, and what step is often missed?

Insert the M.2 module into a PCIe Gen 4 M.2 slot at an angle, then secure it with the single retention screw; forgetting that screw leaves the drive unseated and undetected.

When will the 64GB DDR4 ECC RDIMM memory need expansion or replacement?

The eight DIMM slots support up to 1TB total; add matching DDR4 ECC RDIMMs when workloads exceed the installed 64GB, and replace any module that fails diagnostics.
