Professional Workstation for CAD and 3D Rendering

The Lenovo ThinkStation P620 is a tower workstation built for CAD, 3D modelling, rendering and engineering workflows. It runs on an AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads at a 4.0 GHz base clock. Professional NVIDIA RTX A4000 graphics accelerate GPU-enabled creative applications. Windows 11 Pro provides business-ready security and remote desktop features.

Suits Multi-Core Rendering and Large Projects

This configuration suits professionals who need multi-core performance for rendering, simulation and complex assemblies. The 16GB of installed DDR4 ECC memory supports large project files and virtual machines. Buyers who need higher memory capacity for extreme datasets should look at configurations with more RAM installed. The 1000W power supply supports demanding components and future expansion cards.

Dual RTX A4000 GPUs and High-Capacity Storage

Two NVIDIA RTX A4000 cards double the available GPU memory and compute resources for parallel rendering and viewport tasks. Storage combines a responsive 2TB NVMe M.2 SSD with a 12TB 7200rpm HDD for capacity. Eight DIMM slots and two onboard PCIe Gen 4 NVMe slots allow memory and storage scaling as projects grow.

Questions about this item

Does the 1000W power supply in the P620 provide enough PCIe connectors for both RTX A4000 cards?

The 1000W unit ships with the cables required for the dual RTX A4000 graphics configuration installed in this workstation.

Can I keep my existing DDR4 ECC RDIMM modules when upgrading the 16GB memory in this 8-channel Threadripper PRO system?

Yes, the eight DIMM slots accept DDR4 ECC RDIMMs so compatible modules you already own can be added alongside the factory 16GB.

How do I verify both RTX A4000 GPUs are detected and running at PCIe Gen 4 speed after Windows 11 Pro setup?

Open Device Manager or NVIDIA Control Panel; both cards should appear and show a PCIe x16 Gen 4 link width under the GPU details.
