Lenovo ThinkStation P620 3945WX PRO 4.0GHz 256GB PC4 2x P1000 Design hard drive adapter

Workstation for CAD and Engineering

The Lenovo ThinkStation P620 is a tower workstation built for engineering, drafting, 3D modelling, visualisation and technical design applications. It runs on an AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads at a 4.0 GHz base clock. 256GB of installed DDR4 ECC memory across eight slots supports large project files and smooth multitasking. Windows 11 Pro provides the operating environment.

Check power, slots and graphics needs

Verify that your workspace can accommodate a tower form factor and a 1000W power supply. Confirm the motherboard provides eight DIMM slots for DDR4 ECC RDIMM modules if you plan memory changes. Two built-in PCIe Gen 4 NVMe M.2 slots are available for storage expansion. The included NVIDIA Quadro P1000 handles professional CAD graphics workloads; ensure this matches your software certification requirements.

Replaces older workstation towers

This system upgrades from earlier workstations that lack 8-channel DDR4 ECC memory architecture and PCIe Gen 4 NVMe support. The jump is worth it when rendering, simulation or large assembly tasks exceed the core count, memory bandwidth or storage speed of your current machine. Buyers who need more than two professional GPUs or specialised accelerator cards should review the PCIe slot layout before ordering.
