HP Z820 workstation processors

Multitasking made easy

The HP Z820 Workstation employs a variety of Intel® Xeon® E5-2600 v2 processors that enable next-generation PCI Express technology. With support for two processors, the HP Z820 can operate with up to 24 processing cores, delivering ultimate performance to help you accomplish more. Featuring the C600 series chipset, LSI SAS 2308 controller, and dual Quick Path Interconnects between the processors, the two work together so you work more effectively than ever before. And thanks to optional Thunderbolt technology, you'll transfer data at lightning-fast speeds with the ability to connect to high-resolution displays and high-performance data devices over a single Thunderbolt cable.

Ultra-powerful visuals and high-performance computing

Built to support next generation PCIe Gen3 graphics from AMD and NVIDIA,® the HP Z820 Workstation currently offers a wide range of cards from Pro 2D to ultra high-end 3D graphics to get the job done. With dual graphics processor support, the HP Z820 can drive up to eight displays, giving you the power and space you need to multitask like a pro. Plus, get the highest performing GPU computing solutions available in the Z family, like NVIDIA's Maximus, on the HP Z820.

** Each drive requires a PCIe x4 (minimum) slot to be available. Full performance is obtained only when using PCIe slots connected to the CPU. Non-CPU PCIe slots may see a decrease of up to 10%. Please see slot configuration recommendations at http://www8.hp.com/us/en/campaigns/workstations/z-turbo-drive.html. Note that graphics cards, Thunderbolt, and other devices will require PCIe slots.

  1. Multi-Core is designed to improve performance of certain software products. Not all customers or software applications will necessarily benefit from use of this technology. 64-bit computing system required. Performance will vary depending on your hardware and software configurations. Intel’s numbering is not a measurement of higher performance.
  2. 64-bit computing on Intel® architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel® 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations. See intel.com/info/em64t External link for more information.
  3. Intel's numbering is not a measurement of higher performance.
  4. The specifications shown in this in this column represent the following: (all core maximum turbo steps, one core maximum turbo steps). Turbo boost stepping occurs in 100MHz increments. Processors that do not have turbo functionality are denoted as N/A. NOTE: Turbo [all core, 1C] Ex. 2.9 GHz [4, 9] turbo is 8C turbo to 3.3, 1C turbo to 3.8. Intel® Turbo Boost technology requires a PC with a processor with Intel® Turbo Boost capability. Intel® Turbo Boost performance varies depending on hardware, software, and overall system configuration. Please visit intel.com/technology/turboboost External link for more information.
  5. Each processor supports up to 4 channels of DDR3 memory. To realize full performance at least 1 DIMM must be inserted into each channel.
  6. SATA hardware RAID is not supported on Linux systems. The Linux kernel, with built-in software RAID, provides excellent functionality and performance. It is a good alternative to hardware-based RAID. Please visit h20000.www2.hp.com/bc/docs/support/SupportManual/c00060684/c00060684.pdf for RAID capabilities with Linux.
  7. For hard drives, 1 GB = 1 billion bytes. TB = 1 trillion bytes. Actual formatted capacity is less.
  8. Actual speeds may vary. Does not permit copying of commercially available DVD movies or other copyright protected materials. Intended for creation and storage of your original material and other lawful uses. Note that DVD-RAM cannot read or write to 2.6 GB Single Sided/5.2 GB Double Sided – Version 1.0 media.
  9. As Blu-ray contains new technologies, certain disc, digital connection, compatibility and/or performance issues may arise, and do not constitute defects in the product. Flawless playback on all systems is not guaranteed. In order for some Blu-ray titles to play, they may require a DVI or HDMI digital connection and your display may require HDCP support. HD DVD movies cannot be played on this workstation.
  10. HP Care Pack Services extend service contracts beyond the standard warranties. Service starts from date of hardware purchase. To choose the right level of service for your HP product, use the HP Care Pack Services Lookup Tool at http://h20560.www2.hp.com/portal/site/cpc?ac.admitted=1392942166445.2043657423.1959898185. Additional HP Care Pack Services information by product is available at http://www8.hp.com/us/en/business-services/it-services.html?compURI=1077422. Service levels and response times for HP Care Packs may vary depending on your geographic location.
  11. Thunderbolt is an optional feature available as an add-in card. Install all the latest drivers for your Thunderbolt device before connecting to the Thunderbolt port. Thunderbolt cable and Thunderbolt device (sold separately) must be compatible with Windows. To determine whether your device is Thunderbolt Certified for Windows, see https://thunderbolttechnology.net/products External link.
