Dual Xeon Gold 6148 40-core tower

The Dell Precision 7820 is a new tower workstation equipped with two Intel Xeon Gold 6148 processors, each delivering 20 cores at 2.40 GHz for a total of 40 cores. It includes 64 GB of DDR4 ECC registered memory across 12 slots and a 512 GB SATA SSD. An NVIDIA Quadro P4000 with 8 GB video memory and Windows 11 Pro complete the professional configuration.

Suits CAD and rendering.

This system targets engineers, designers and content creators who rely on certified drivers for CAD, 3D rendering and multi-display workflows. The dual-socket LGA 3647 platform supports memory-intensive tasks and high core-count parallel workloads. Buyers who need more than 8 GB of GPU memory or a newer GPU architecture for advanced compute workloads should look elsewhere.

Single-socket limit fixed at two Xeon Gold 6148 CPUs

The motherboard accepts a maximum of two processors and both sockets are already populated with Xeon Gold 6148 units. No further CPU upgrades are possible without replacing the processors entirely. This hard limit defines the workstation's peak processing capacity for the life of the system.

Questions about this item

Should I pick the 64 GB DDR4 ECC configuration or look for a larger memory option?

The system ships with 64 GB of DDR4 ECC registered memory across 12 slots, leaving room to expand up to the platform maximum if your workloads demand more capacity.

What does the dual 20-core Xeon Gold 6148 at 2.4 GHz deliver in actual workloads?

Forty total cores at 2.4 GHz provide strong parallel throughput for rendering, simulation and multi-threaded engineering tasks, with ECC memory protecting data integrity during long compute runs.

How does the SATA SSD interface affect the 512 GB drive's real-world speed?

The 512 GB drive uses a SATA interface, giving fast boot and application load times for everyday professional work while sequential transfers are limited to the SATA bus ceiling.
