Lenovo ThinkStation P620 Threadripper 3945WX 4.0GHz 32GB 1TB NVMe 2TB HDD RTX A2000 12GB W11 Pro

Professional Workstation Configuration

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D rendering, engineering and creative production. It ships with an AMD Ryzen Threadripper PRO 3945WX processor running at 4.0 GHz base with 12 cores and 24 threads. Installed memory totals 32 GB across eight DDR4 ECC RDIMM slots. Windows 11 Pro provides the operating environment.

Upgrade Path From Entry Systems

This configuration replaces single-socket desktops that stall on large assemblies or multi-application workloads. The jump is worth it when project files exceed typical consumer memory limits or when GPU-accelerated viewport performance becomes a daily bottleneck. Eight memory slots and two onboard PCIe Gen 4 NVMe M.2 slots allow capacity to grow with the workload.

Sustained Load Behaviour

A 1000 W power supply feeds the RTX A2000 12 GB graphics card and the 4.30 GHz boost processor during extended render queues. The storage mix pairs a 1 TB NVMe drive for active projects with a 2 TB 7200 rpm HDD for archives. Multiple PCIe Gen 4 expansion slots support additional GPUs or storage controllers without throttling under continuous demand.
