DELL Precision 5820 Tower Xeon W-2255 10-core 32GB DDR4 1TB NVMe Quadro P5000 desktop PC

Precision 5820 Xeon workstation

The Dell Precision 5820 Tower is a mid-tower workstation built around a 10-core Intel Xeon W-2255 processor with a 3.7 GHz base clock and 4.7 GHz turbo frequency. It ships with 32 GB of DDR4-2933 registered ECC memory across eight slots and a 1 TB PCIe NVMe solid-state drive. NVIDIA Quadro P5000 graphics with 16 GB GDDR5X memory drives four DisplayPort outputs, while Windows 11 Pro provides the operating environment.

Upgrading from entry workstations

This system replaces older single-socket towers that max out at lower core counts, slower memory speeds or limited GPU memory. The jump is worth it when workloads demand 10 cores of Xeon performance, ECC memory integrity and a 256-bit professional graphics card with 16 GB of frame buffer for multi-display CAD, simulation or rendering pipelines.

Sustained load behaviour

A 950 W 80 Plus Gold power supply rated at 90 percent efficiency feeds the CPU, GPU and memory subsystem during extended compute or render sessions. The tower chassis and component selection are engineered for continuous operation rather than short bursts, keeping thermals stable while the Xeon maintains high turbo frequencies across all cores under prolonged multi-threaded demand.
