Dell Precision 7920
A dual-socket Intel Xeon Scalable tower for rendering, simulation, CAD and other parallel workloads. The second processor is what unlocks the remaining 12 DIMM slots and two of the x16 graphics slots, so decide your memory and GPU targets before you choose a single- or dual-processor build.

Plan a complete configuration
Processor & memory
Match your application requirements to the supported processor family. Verify DIMM type, occupied slots and population rules; installed CPU count can affect available memory and expansion.
Graphics & expansion
Confirm graphics-card dimensions, occupied PCIe slots, PSU capacity, power connectors and application certification.
Condition & delivery
Compare the complete configured price, warranty terms and lead time. Include your quantity, destination and preferred condition when requesting a quote.
Common questions
Can I configure and buy this model online?
Yes. Use Configure & Buy to open the current CTO listing and choose its available options. Contact us for requirements outside that listing.
Does the specification sheet describe my exact system?
No. It describes platform options for its document edition. Check your installed processor, memory, chassis, controller, power supply and expansion components before selecting parts.
