Lenovo ThinkStation P620 Threadripper 3945WX 4.0GHz 256GB 1TB NVMe 2TB HDD RTX A2000 12GB W11 Pro

Professional CAD Workstation

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D modeling, rendering, engineering visualization, and creative production. It uses an AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads running at a 4.0 GHz base frequency. The system ships with Windows 11 Pro for modern security and remote desktop features. Professionals needing certified drivers for ISV applications will find this platform suitable.

256GB Memory and Dual-Drive Storage

Installed memory totals 256GB across eight DDR4 ECC RDIMM slots, leaving headroom to reach the 1TB maximum supported capacity for larger datasets and virtual machines. A 1TB NVMe M.2 SSD provides fast boot and active-project access, while a 2TB 7200rpm HDD adds bulk capacity for archives and backups. The motherboard includes two built-in PCIe Gen 4 NVMe M.2 slots for future expansion. Workloads exceeding 256GB active memory or requiring faster scratch disks will need upgrades.

RTX A2000 Graphics and 1000W Power

The NVIDIA RTX A2000 with 12GB VRAM accelerates CAD, 3D visualization, rendering, and GPU-enabled creative applications. A 1000W power supply delivers overhead for the current configuration and supports additional PCIe Gen 4 expansion cards such as extra GPUs, networking, or NVMe storage. Buyers who require more than 12GB VRAM for massive scenes or who need multiple high-power GPUs should verify total power budget before expanding.
