Professional CAD Workstation

The Lenovo ThinkStation P620 tower is built for CAD, 3D modeling, rendering, engineering visualization and creative production. It runs on an AMD Ryzen Threadripper PRO 3945WX processor with 12 cores and 24 threads at a 4.0 GHz base frequency. The system includes 48GB of DDR4 ECC memory across 8 DIMM slots and an NVIDIA RTX 4000 graphics card. Windows 11 Pro is installed for professional security and remote desktop features.

Thermals Noise Power

A 1000W power supply delivers stable energy to the Threadripper PRO CPU, RTX 4000 GPU, 2TB NVMe SSD and 4TB 7200rpm HDD during typical professional workloads. The tower form factor provides airflow for the processor, graphics card and storage devices under normal office or studio conditions. Windows 11 Pro power management balances performance and acoustics for daily CAD, modeling and multitasking sessions.

Sustained Load Behaviour

Under continuous rendering, simulation or engineering compute tasks the 12-core Threadripper PRO 3945WX can boost toward 4.30 GHz while the RTX 4000 maintains GPU acceleration for visualization and GPU-enabled applications. The 1000W unit supports prolonged multi-component draw and the 8-channel DDR4 architecture sustains memory bandwidth for large project files. Builders who need a second graphics card or additional NVMe storage beyond the two onboard M.2 slots should verify expansion capacity before purchase.

Questions sur cet article

How do I install the AMD Ryzen Threadripper PRO 3945WX CPU into the ThinkStation P620, and what step is often missed?

The processor is already installed in the workstation; no CPU installation is required.

What maintenance or replacement will the 4TB HDD and 2TB NVMe storage need later?

The 7200rpm HDD may need replacement after years of continuous operation; the NVMe SSD has no moving parts and typically lasts the system's life.

What limit appears first on the RTX 4000 during sustained rendering workloads?

The RTX 4000 graphics card will hit its thermal or power envelope before the 1000W supply or 48GB memory become bottlenecks.
