The Precision 7920 Tower combines versatile design and ultimate storage scalability to grow with your vision no matter where it takes you.
Next gen performance: Power through your most complex and demanding applications quickly and efficiently with a new generation of dual-socket performance. Featuring the latest Intel® Xeon® processor Scalable family with up to 28 cores per processor or a total of 56 cores when customized with Dual processors.
Room for everything: With up to 3TB of 2666 MHz RDIMM/LRDIMM expandable memory, you can accelerate your workflow without slowdown. Now with a 6-channel memory architecture up to 3.0 TB total with select CPUs (requires dual processors).
Stay cool under pressure: Featuring a new multichannel thermal design for advanced cooling and acoustics- for a quieter overall system under heavy workloads.
No project is too big: Work with more flexibility thanks to a new FlexBay design with up to 10x2.5"/3.5" SATA/SAS drives or up to 4x M.2 or U.2 PCIe NVMe SSD. With the hot-swap feature on the M.2 and U.2 PCIe NVMe SSDs, you can remove drives without shutting down the workstation.
Stay flexible with ultimate scalability: Featuring a FlexBay design, front access, hot swappable storage and multichannel thermals to keep it cool under pressure, the Precision 7920 Tower combines versatile design and ultimate storage scalability to grow with your vision no matter where it takes you.
As adaptable as you are: There is no limit to your potential on this machine designed for the future. Your Precision workstation is ready for complex projects, including virtual reality workflows, with the next generation AMD Radeon Pro™ and highest-performing NVIDIA Quadro® graphics.
A sight to behold: Your fixed workstation supports up to 900W of graphics power and up to 3 double width graphics cards up to 300W each including consumer cards.
Tuned performance: Free with your Precision workstation, the Dell Precision Optimizer delivers faster application optimization with a single click compared to HP Advisor*. It also automatically tunes your workstation to run popular ISV applications at the fastest speeds possible, has automated system updates and provides analytics to address resource bottlenecks.
Premium customized performance: Upgrade to the new Dell Precision Optimizer premium version, the world’s first AI-based performance optimizer software for workstations*. This program learns the behavior of any user-specified applications, identifies optimization opportunities using machine learning and applies performance improvements.
Stay safe, stay secure
Reduce downtime with Dell Reliable Memory Technology (RMT) Pro. Designed to work with ECC memory, RMT protects your machine from potential crashes by mapping out bad memory locations after the system reboots.
Reliably access your data
Improve the availability of your data with hardware and software optional RAID storage options including PCIe NVMe SSDs.
Your work can count on it
Precision Workstations are tested to ensure the high-performance applications you rely on every day run smoothly. Dell ISV-certifications cover the most popular independent software applications.
