Dual Xeon Gold 6144 workstation

The Dell Precision T7920 tower carries two Intel Xeon Gold 6144 processors running at 3.5 GHz with 16 cores and 32 threads. It ships with 768 GB of DDR4-2666 ECC memory and a 500 GB NVMe M.2 SSD on a PCIe adapter card. An AMD Radeon Pro WX 7100 with 8 GB GDDR5 handles graphics duties. Windows 10 Pro is pre-installed and the 1400 W supply powers the build.

Memory ceiling and expansion

The platform supports up to 1536 GB of total memory across 24 DIMM slots arranged in six channels per CPU pair. DDR4-2666 ECC modules are required; other DDR generations will not fit. The single 500 GB NVMe drive provides fast OS and application loading while the DVD±RW drive remains for legacy media. No mechanical hard drive is included.

Graphics certification scope

The Radeon Pro WX 7100 is a certified card for AutoCAD workflows that rely on DirectX 11 or later support. Buyers who need Nvidia Quadro certification for other ISV applications should verify compatibility before purchase. The workstation targets professionals who need dual-socket compute density and large memory capacity in a tower form factor.

Questions about this item

Should I choose the 768GB DDR4-2666 ECC configuration or add more modules later?

The system ships with 768GB across 24 DIMM slots, six channels per CPU at 2666MHz. All slots are populated, so expansion requires replacing modules up to the 1536GB maximum.

What does the 3.5GHz base clock on the dual Xeon Gold 6144 CPUs deliver in a real workload?

Sixteen physical cores and 32 threads at 3.5GHz give strong single-thread speed for CAD modelling and enough parallel threads for rendering jobs.

How does the PCIe 3.0 x4 link for the 500GB NVMe M.2 drive cap real-world throughput?

The NVMe SSD on its PCIe adapter card runs over a PCIe 3.0 x4 connection, limiting sequential reads to roughly 3.5GB/s in practice.
