Precision 5820 Tower Workstation

The Dell Precision 5820 is a mid-tower workstation built for professional workloads. It ships with Windows 11 Pro and includes no monitor. The system targets engineers, designers and analysts who need certified stability for compute-intensive applications.

Xeon W-2135 6-Core Processor

The Intel Xeon W-2135 runs at 3.7 GHz with a 4.5 GHz turbo frequency across six cores on the LGA 2066 socket. This CPU specification determines whether the workstation meets the thread-count and clock-speed requirements of your licensed software stack.

64GB DDR4 ECC and Quadro P5000

The 64 GB of registered ECC DDR4 2666 memory and the Nvidia Quadro P5000 with 16 GB GDDR5X suit users running large assemblies, simulation datasets or multi-display visualisation. Buyers who need more than 256 GB total memory capacity or a different GPU architecture should evaluate alternative configurations.

Questions about this item

How does the 3.7 GHz base clock with 4.5 GHz turbo affect real-world workloads on this Xeon W-2135?

The six-core Xeon W-2135 runs at 3.7 GHz base and can boost to 4.5 GHz, giving strong single-thread speed for CAD and simulation tasks while keeping all cores active for rendering.

What does the PCIe 3.0 x16 slot limit mean for the Quadro P5000 in this tower?

The Quadro P5000 connects through a PCIe 3.0 x16 slot, so host-to-GPU transfers peak at the bandwidth of that generation while the card's own 256-bit GDDR5X memory handles frame-buffer traffic.

Will the 950 W power supply and mid-tower chassis fit the Quadro P5000 and 64 GB of registered ECC memory?

Yes, the 950 W 80 Plus Gold unit powers the Quadro P5000 and the four 16 GB DDR4 2666 registered ECC modules installed in the eight available slots.
