Dell Precision 5820 Tower Workstation Xeon W-2135 16GB DDR4 1TB NVMe Quadro P4000 Windows 11 Pro

Precision 5820 Xeon Workstation

The Dell Precision 5820 Tower is a mid-tower workstation built for professional workloads. It ships new with a 6-core Intel Xeon W-2135 processor running at 3.7 GHz with a 4.5 GHz turbo frequency. The system includes 16 GB of DDR4 2666 registered ECC memory across eight slots and a 1 TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 graphics card with 8 GB GDDR5 and four DisplayPort outputs drives multiple displays. Windows 11 Pro is pre-installed and digitally activated.

Upgrading from Entry Workstations

This configuration replaces older single-socket towers that max out at four cores or lack ECC memory support. The jump is worth it when applications demand registered DDR4 error correction, more than 64 GB of total memory headroom, or a 256-bit professional GPU for certified drivers. Builders staying with consumer-grade processors or non-ECC memory will not gain the stability this platform provides. The 950 W 80 Plus Gold power supply supports the installed components without extra cables.

16 GB Memory and 1 TB Storage Headroom

The 16 GB (2 x 8 GB) DDR4 2666 kit handles typical CAD, simulation and rendering datasets while leaving six slots open for expansion up to 256 GB. The 1 TB NVMe drive accommodates active projects and OS scratch space; larger model libraries or raw footage archives will require secondary storage. The Quadro P4000 8 GB frame buffer suits moderate 3D viewports and GPU compute; scenes exceeding that capacity will spill to system memory. No mechanical drive bay is populated, so bulk storage must be added separately.
