DELL Precision T5820 desktop PC Xeon W-2155 10-core 64GB DDR4 2TB NVMe Quadro P5000

Precision T5820 Workstation

The Dell Precision T5820 is a mid-tower workstation built for professionals who need a Xeon W-2155 processor with 10 cores running at 3.3 GHz and a turbo frequency of 4.5 GHz. It ships with 64 GB of DDR4 2666 registered ECC memory and a 2 TB NVMe SSD. The Nvidia Quadro P5000 graphics card provides 16 GB of GDDR5X video memory and four DisplayPort outputs for multi-monitor setups. Windows 11 Pro is pre-installed and digitally activated.

Build Integration

The system uses an LGA 2066 socket motherboard with eight memory slots, allowing expansion up to 256 GB of DDR4 2666 ECC memory. A 950 W 80 Plus Gold certified power supply rated at 90 % efficiency delivers power to the CPU, GPU and storage. Integrated Intel i219 Gigabit Ethernet and Realtek ALC3234 high-definition audio handle networking and sound without additional cards. The mid-tower chassis provides internal space for the installed components and standard expansion cards.

Sustained Load Behaviour

The Xeon W-2155 maintains its 3.3 GHz base clock across all 10 cores during extended compute tasks, with thermal headroom managed by the workstation cooling design. The Quadro P5000's 16 GB GDDR5X frame buffer supports large datasets and complex 3D scenes without swapping to system memory. ECC memory corrects single-bit errors in real time, preserving data integrity during long rendering or simulation runs. The Gold-rated power supply sustains high output with minimal efficiency loss under continuous demand.
