Dell Precision T5820 Tower Workstation Xeon W-2255 10 Core 16GB DDR4 500GB NVMe Quadro P4000 Windows 11 Pro

Precision T5820 Xeon workstation

The Dell Precision T5820 is a mid-tower workstation built around an Intel Xeon W-2255 processor with ten cores running at 3.7 GHz and a 4.7 GHz turbo frequency. It ships with 16 GB of DDR4 2933 MHz registered ECC memory and a 500 GB NVMe SSD. The Nvidia Quadro P4000 graphics card provides 8 GB of GDDR5 memory and four DisplayPort outputs. Windows 11 Pro 64-bit is pre-installed for professional workloads.

Build integration and expansion

The system uses an LGA 2066 socket and offers eight total memory slots supporting up to 256 GB of DDR4, leaving six slots free for future upgrades. A 950 W 80 Plus Gold power supply rated at 90 percent efficiency delivers ample headroom for additional drives or cards. Integrated Intel i219 Gigabit Ethernet and Realtek ALC3234 audio handle networking and sound without extra cards. No monitor is included, so a display must be sourced separately.

Capacity and headroom

The ten-core Xeon and Quadro P4000 combination handles multi-threaded compute tasks and professional 3D applications with 8 GB of dedicated graphics memory. Sixteen gigabytes of ECC RAM suits moderate datasets, while the 256 GB ceiling allows substantial expansion for larger simulations. The single 500 GB NVMe drive provides fast boot and scratch space, though storage-heavy projects will require additional drives. Buyers who need more GPU memory or higher core counts should look elsewhere.
