Brainpower that matches yours: The latest Intel® Xeon® processor Scalable Family powers your most demanding applications. Now featuring a new generation of dual-socket architecture with up to 28 cores per processor (or up to 56 cores when built with dual processors) so you can extract maximum performance for your greatest vision.
Accelerate every project: Run your software as fast as possible and get real-time results thanks to this memory expandable machine with up to 768GB of 2933 MHz RDIMM memory.
Drown out distraction: Focus on your tasks with the workstation that’s quieter than ever. A new multichannel thermal design delivers advanced cooling and acoustics for enhanced cooling and quiet operation when your system is under heavy workloads.
Featuring a FlexBay design, front access, hot-swappable storage and multichannel thermals to keep it cool under pressure, the Precision 7820 Tower grows with your ideas no matter where they take you.
Adapts to your innovations: Your Precision 7820 Tower is ready for complex projects, including virtual reality and AI workflows, with the next generation AMD Radeon Pro™ and highest-performing NVIDIA Quadro® RTX graphics. Your workstation supports up to 600W of graphics power up to 300W per card (single CPU system).
No project is too big: Up to six 2.5" or five 3.5" drives and front access storage including SATA, SAS and PCIe M.2/U.2 NVMe SSD can be configured for up to 68TB total storage and easily swapped. With the hot-swap feature on the M.2 and U.2 PCIe NVMe SSDs, you can remove drives without shutting down the workstation. Enable increased storage performance with the optional U.2 Intel® Optane™ SSD 905P Solid State Drives.
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 workstation*. This program learns the behavior of any user-specified applications, identifies optimization opportunities using machine learning and applies performance improvements.
