Professional Workstation Tower

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D rendering and engineering workflows. It runs an AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads at a 4.0 GHz base clock. The system includes 192 GB of DDR4 ECC memory across eight slots and an NVIDIA RTX A2000 graphics card with 12 GB VRAM. Windows 11 Pro comes pre-installed.

PCIe Gen 4 Storage Limits

Two onboard PCIe Gen 4 NVMe M.2 slots provide the primary high-speed storage interface. The supplied configuration uses one slot for a 2 TB NVMe drive while the second remains open for expansion. Additional NVMe devices require add-in cards that occupy PCIe Gen 4 expansion slots shared with GPU and networking upgrades. A single 4 TB 7200 rpm hard drive supplies bulk capacity on a separate interface.

Installation Notes

The 1000 W power supply supports the factory graphics card and leaves headroom for further add-in cards, but total draw must stay within that limit. Memory upgrades use the eight DDR4 ECC RDIMM slots and can reach 1 TB when all are populated with compatible modules. Physical clearance for long expansion cards should be verified inside the tower chassis before purchase.

Target Users & Exclusions

This workstation suits professionals who need certified drivers and ECC memory for stable CAD and rendering pipelines. Buyers who want more storage than the two M.2 slots plus one 3.5-inch bay can provide without extra controllers are not served by the base configuration. Users seeking consumer-grade gaming features or non-ECC memory optimisations should look elsewhere.

Questions about this item

Should I pick the 4 TB hard drive or the 2 TB NVMe SSD for my active project files?

Use the 2 TB NVMe SSD for active project files and the operating system; its PCIe Gen 4 interface delivers the responsive speed that CAD and rendering workloads demand. The 4 TB 7200 rpm hard drive is better suited for archived data, backups and larger media libraries where capacity matters more than access time.

What does the 4.0 GHz base clock on the Threadripper PRO 3945WX mean when I am rendering a scene?

The 12-core, 24-thread CPU runs at a guaranteed 4.0 GHz base frequency across all cores during sustained rendering, and can boost to 4.30 GHz on lighter threads, giving predictable multi-core throughput for long compute jobs.

How many PCIe Gen 4 NVMe drives can the P620 actually support?

The workstation provides two built-in PCIe Gen 4 M.2 slots for NVMe SSDs, and additional PCIe Gen 4 expansion slots allow add-in cards that can host further NVMe drives for storage scaling.
