Precision T7920 dual Xeon workstation

This new Dell Precision T7920 tower workstation ships with two Intel Xeon Gold 5122 processors running at 3.6 GHz, delivering 8 cores and 16 threads. It targets engineers and designers who run certified CAD applications and need ECC memory stability. The system arrives with Windows 10 Pro installed and a 1400 W power supply.

Memory and graphics configuration

1536 GB of DDR4 2666 ECC memory fills 24 DIMM slots across two CPUs, reaching the platform maximum. An AMD Radeon Pro WX 7100 with 8 GB GDDR5 provides dedicated GPU acceleration for DirectX 11 workloads. A 1 TB NVMe M.2 SSD on a PCIe adapter card handles boot and active project storage.

LGA 3647 socket constraint

The dual LGA 3647 socket design means any future processor upgrade must use compatible Xeon Scalable parts. Buyers who need a different socket type or single-socket simplicity should consider other platforms.

Questions about this item

How much DDR4-2666 ECC memory can I add later using the 24 DIMM slots?

The board supports up to 1536 GB total across 24 slots, so you can expand until that ceiling is reached.

What thermal limit will the dual Xeon Gold 5122 CPUs hit first during long renders?

Each processor runs at 3.6 GHz base clock; sustained all-core loads will reach its thermal design envelope before any other component throttles.

How loud and hot does the 1400 W supply get when the Radeon Pro WX 7100 and both CPUs run all day?

The 1400 W unit powers both 3.6 GHz Xeons and the 8 GB GDDR5 GPU; expect noticeable fan noise and warm exhaust under continuous full load.
