DELL Precision 5820 Tower Workstation Xeon W-2123 256GB DDR4 1TB NVMe Quadro P4000

Precision 5820 Tower Workstation

The Dell Precision 5820 Tower Workstation is built around an Intel Xeon W-2123 3.6GHz (3.9GHz Turbo) 4 Core Processor. It ships with 256GB DDR4 2666MHz Registered ECC memory across eight slots. A 1TB PCIe NVMe solid-state drive provides primary storage. The Nvidia Quadro P4000 graphics card adds 8GB GDDR5 memory and four DisplayPort outputs. Windows 11 Pro is pre-installed for professional environments.

Upgrading from entry systems

This configuration replaces desktop platforms limited to consumer processors and non-ECC memory. The jump is worth it when workloads require registered ECC DDR4 at 2666MHz and a 950 Watt 80 Plus Gold certified power supply delivering 90% efficiency. The Xeon W-2123 on LGA 2066 supports multi-threaded compute that consumer sockets cannot sustain. Buyers who need more than 256GB memory capacity or higher core counts must evaluate alternative workstation classes.

LGA 2066 and Quadro P4000 limits

The LGA 2066 socket caps memory at 256GB DDR4 across eight slots, matching the installed configuration. The Quadro P4000 uses a 256-bit GDDR5 interface with four DisplayPort connectors, limiting display outputs to four panels. The 950 Watt power supply defines the ceiling for additional internal cards or drives. Integrated Intel i219 Gigabit Ethernet and Realtek ALC3234 audio remain fixed on the motherboard.
