Lenovo ThinkStation P620 3945WX 4.0GHz 192GB RTX 4000 2TB NVMe 12TB HDD W11 Pro

Workstation for CAD and 3D rendering

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D modeling, rendering, engineering visualization, 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. 192GB of DDR4 ECC RDIMM memory is installed across eight slots. An NVIDIA RTX 4000 graphics card accelerates professional GPU-enabled applications. Windows 11 Pro provides modern security, networking, and remote desktop features.

Suits professionals needing high core counts

This system suits engineers, architects, and content creators who rely on multi-threaded CPU performance, large memory capacity, and professional graphics drivers for certified applications. The 1000W power supply supports demanding components and add-in cards. Buyers who need a compact form factor or integrated graphics for basic office tasks should consider other options. The tower chassis requires adequate desk or floor space.

Handles large projects with fast primary storage

The 2TB NVMe M.2 drive delivers responsive solid-state performance for operating system, applications, and active project files. A 12TB 7200rpm HDD provides additional capacity for media, backups, and archived data. Memory can be expanded up to 1TB via the eight DIMM slots for virtual machines and massive datasets. PCIe Gen 4 expansion slots allow further GPU, networking, or NVMe scaling. The single RTX 4000 may limit multi-GPU rendering workflows.
