Dual Xeon Gold 5122 workstation

The Dell Precision 7920 tower houses two Xeon Gold 5122 processors, each running at 3.6 GHz with four cores and eight threads. Together they provide 16 logical threads for multi-threaded professional applications. The system ships with 1536 GB of DDR4 2666 ECC memory across 24 DIMM slots and a 250 GB NVMe M.2 SSD on a PCIe adapter card. Windows 10 Pro is pre-installed.

Sustained multi-core throughput

A 1400 W power supply feeds both CPUs and the Radeon Pro WX 7100 8 GB GDDR5 graphics card under continuous load. The tower form factor allows airflow across the six-channel memory architecture and dual-socket board during long render or simulation sessions. ECC memory corrects single-bit errors without halting the workload. The DVD±RW drive remains available for archival media.

1536 GB DDR4 2666 ECC capacity

Memory capacity is the defining specification for large assemblies and point-cloud datasets. The 24-slot design populates every channel for maximum bandwidth at 2666 MT/s. Buyers who need more than 1536 GB of RAM cannot expand this chassis further. The 250 GB NVMe boot drive holds the OS and applications; additional storage must be added separately.

Questions about this item

How much power does the 1400w supply draw when the dual Xeon Gold 5122 CPUs and Radeon Pro WX 7100 run all day?

The 1400w power supply is rated to deliver up to 1400 watts; actual draw depends on workload but the unit is sized for the dual 3.6Ghz Xeons and 8GB GDDR5 GPU running continuously.

What display connector must my monitor have to work with the Radeon Pro WX 7100?

The Radeon Pro WX 7100 provides DisplayPort outputs; your monitor needs a DisplayPort input or an active adapter to HDMI or DVI.

Will my existing DDR4-2666 ECC modules fit the 24 DIMM slots alongside the installed 1536GB?

Yes, the 24 slots accept DDR4-2666 ECC RDIMMs; you can add matching modules up to the 1536GB maximum supported with dual CPUs.
