Workstation for CAD and rendering

The Lenovo ThinkStation P620 is a tower workstation configured for CAD, 3D modeling, rendering, engineering and creative production. An AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads runs at a 4.0 GHz base frequency and a 4.30 GHz boost. 48 GB of DDR4 ECC memory is installed across eight slots, with support up to 1 TB total.

Check power, slots and OS needs

Verify that a 1000 W power supply meets the demands of your planned add-in cards and storage expansions. The system provides two onboard PCIe Gen 4 NVMe M.2 slots and multiple PCIe Gen 4 expansion slots for additional GPU, networking or NVMe scaling. Windows 11 Pro is pre-installed, so confirm application compatibility with this operating system before ordering.

Suits professional visualization workloads

This configuration suits engineers, designers and content creators who need professional NVIDIA RTX 4000 graphics acceleration and high-capacity 24 TB HDD plus 4 TB NVMe storage for large project files. It is not intended for buyers who require a compact form factor, silent operation, or a workstation certified for a different ISV suite.

Questions about this item

What comes in the box and what must I buy separately?

The workstation includes the tower, 48 GB DDR4 ECC memory, 2 × 2 TB NVMe M.2 SSDs, 2 × 12 TB 7200 rpm HDDs, an NVIDIA RTX 4000 graphics card, a 1000 W power supply, Windows 11 Pro, and standard accessories. No additional parts are required for the listed configuration.

How do I choose between the two NVMe SSDs and the two 12 TB hard drives?

Use the 2 TB NVMe drives for the operating system, applications, and active project files to benefit from PCIe Gen 4 speed. Use the 12 TB hard drives for bulk storage, archives, and backups where capacity matters more than access time.

What does the 4.0 GHz base clock mean for real-world rendering and simulation workloads?

The Threadripper PRO 3945WX runs its 12 cores at 4.0 GHz base and can boost to 4.30 GHz, delivering sustained multi-threaded performance for CAD, 3D rendering, and engineering simulations without thermal throttling thanks to the 1000 W supply and tower cooling.
