Dell Precision T5820 desktop PC Xeon W-2135 256GB DDR4 2TB NVMe Quadro P4000

Dell Precision T5820 Xeon Workstation

The Dell Precision T5820 is a mid-tower workstation built around an Intel Xeon W-2135 six-core processor running at 3.7 GHz with a 4.5 GHz turbo frequency. It ships with 256 GB of DDR4 2666 MHz registered ECC memory installed across eight slots, reaching the platform maximum. A 2 TB PCIe NVMe solid-state drive provides the primary storage, and an Nvidia Quadro P4000 graphics card with 8 GB GDDR5 memory drives up to four DisplayPort monitors. Windows 11 Pro is pre-installed.

Suited for memory-intensive professional workloads

This system suits engineers, analysts and content creators who need large ECC memory capacity and certified professional graphics for CAD, simulation or video editing. The six-core Xeon and 256 GB RAM combination handles multi-threaded compute and large datasets. Buyers who need more than six CPU cores, higher single-thread frequencies, or consumer-grade gaming features should look at something else. The workstation also lacks a second graphics card, so configurations requiring multi-GPU scaling are not supported.

256 GB DDR4 ECC and 2 TB NVMe headroom

The 256 GB DDR4 2666 MHz registered ECC memory fills every slot, giving full capacity for in-memory databases, large assemblies or virtual machines without paging. The 2 TB NVMe drive accommodates active projects, scratch files and operating system images with fast sequential throughput. When workloads grow beyond 256 GB RAM or require more than 8 GB GPU memory for frame buffers, this configuration runs out of headroom and a platform with higher memory limits or larger GPU VRAM would be required.
