DELL Precision 7920 Tower 2x Xeon Gold 6144 768GB 250GB NVMe Radeon Pro WX 7100

Dual Xeon Gold 6144 workstation

The Dell Precision 7920 Tower pairs two Intel Xeon Gold 6144 processors, each with eight cores at 3.5 GHz, delivering 16 cores and 32 threads for multi-threaded professional applications. It ships with 768 GB of DDR4-2666 ECC memory across 24 DIMM slots and a 250 GB NVMe M.2 SSD on a PCIe adapter card. The AMD Radeon Pro WX 7100 adds 8 GB of GDDR5 graphics memory. Windows 11 Pro is pre-installed.

Sustained multi-core throughput

A 1400 W power supply feeds both CPUs and the GPU, allowing the 32-thread configuration to maintain 3.5 GHz clocks during extended rendering or simulation runs without thermal throttling. Six-channel memory per socket keeps bandwidth high when all 768 GB are active, and ECC protection corrects single-bit errors that could otherwise corrupt long calculations. The tower chassis provides airflow scaled for continuous dual-socket load rather than brief bursts.

Platform limits and expansion

The LGA 3647 platform supports up to 1536 GB of total DDR4-2666 memory when all 24 slots are populated, so the current 768 GB leaves headroom for future upgrades. The NVMe drive uses a PCIe adapter card, consuming one expansion slot but freeing M.2 positions for additional storage. The Radeon Pro WX 7100 occupies a double-width PCIe slot, and the DVD±RW drive uses a 5.25-inch bay, leaving remaining slots for specialised I/O or further GPU compute cards.
