Lenovo ThinkStation P620 Threadripper PRO 3945WX 4.0GHz 64GB RTX A4000 1TB NVMe 2x2TB SATA SSD W11 Pro

Threadripper PRO Workstation for Professional

The Lenovo ThinkStation P620 is a tower workstation built around the AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads running at 4.0 GHz base and 4.30 GHz boost. It targets engineers, 3D artists, and CAD professionals who need certified stability for rendering, simulation, and complex modelling tasks. Eight DIMM slots provide an eight-channel DDR4 ECC memory architecture for data integrity.

64GB Memory and 5TB Mixed Storage Configuration

The system ships with 64GB of installed RAM across the eight slots, leaving headroom to reach the 1TB maximum supported capacity for larger datasets and virtual machines. Storage combines a 1TB NVMe M.2 drive for operating system and active projects with two 2TB SATA SSDs totalling 5TB, balancing low-latency access with high-capacity project libraries and backups.

NVIDIA RTX A4000 Graphics

The NVIDIA RTX A4000 adds professional GPU acceleration for CAD, visualisation, and GPU-enabled creative applications, backed by a 1000W power supply that supports additional expansion cards and storage scaling. Buyers who require more than 12 CPU cores, higher single-thread frequencies, or multiple high-end GPUs will need a different platform. Windows 11 Pro provides the operating environment.
