Downloads and Software

Launch Date

The date the product was first introduced.

TDP

Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements.

Use Conditions

Use conditions are the environmental and operating conditions derived from the context of system use.
For SKU specific use condition information, see PRQ report.
For current use condition information, see Intel UC (CNDA site)*.

Embedded Options Available

Embedded Options Available indicates products that offer extended purchase availability for intelligent systems and embedded solutions. Product certification and use condition applications can be found in the Production Release Qualification (PRQ) report. See your Intel representative for details.

PCI Express Revision

PCI Express Revision is the version supported by the processor. Peripheral Component Interconnect Express (or PCIe) is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer. The different PCI Express versions support different data rates.

PCI Express Configurations

PCI Express (PCIe) Configurations describe the available PCIe lane configurations that can be used to link the PCH PCIe lanes to PCIe devices.

Max # of PCI Express Lanes

A PCI Express (PCIe) lane consists of two differential signaling pairs, one for receiving data, one for transmitting data, and is the basic unit of the PCIe bus. # of PCI Express Lanes is the total number supported by the processor.

USB Revision

USB (Universal Serial Bus) is an industry standard connection technology for attaching peripheral devices to a computer.

Total # of SATA Ports

SATA (Serial Advanced Technology Attachment) is a high speed standard for connecting storage devices such as hard disk drives and optical drives to a motherboard.

Integrated LAN

Integrated LAN indicates the presence of an integrated Intel Ethernet MAC or presence of the LAN ports built into the system board.

PCIe* Uplink

PCIe Uplink is an option to use additional PCIe lanes to the PCH, dedicated to storage bandwidth.

Intel® Virtualization Technology for Directed I/O (VT-d)

Intel® Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium® processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments.

Intel® vPro™ Platform Eligibility

Intel® vPro™ Technology is a set of security and manageability capabilities built into the processor aimed at addressing four critical areas of IT security: 1) Threat management, including protection from rootkits, viruses, and malware 2) Identity and web site access point protection 3) Confidential personal and business data protection 4) Remote and local monitoring, remediation, and repair of PCs and workstations.

Intel® HD Audio Technology

Intel® High Definition Audio (Intel® HD Audio) is capable of playing back more channels at higher quality than previous integrated audio formats. In addition, Intel® HD Audio has the technology needed to support the latest and greatest audio content.

Intel® Rapid Storage Technology enterprise

Intel ® Rapid Storage Technology enterprise (Intel ® RSTe) provides performance and reliability for supported systems equipped with Serial ATA (SATA) devices, Serial Attached SCSI (SAS) devices, and/or solid state drives (SSDs) to enable an optimal enterprise storage solution.

Integrated Intel® QuickAssist Technology

Intel® QuickAssist Technology provides security and compression acceleration capabilities used to improve performance and efficiency across the data center.

Intel® Node Manager

Intel® Intelligent Power Node Manager is a platform resident technology that enforces power and thermal policies for the platform. It enables data center power and thermal management by exposing an external interface to management software through which platform policies can be specified. It also enables specific data center power management usage models such as power limiting.

Intel® Standard Manageability

Intel® Standard Manageability is a base set of manageability features, including: Boot Control, Power State Management, HW Inventory, Serial Over LAN, and Remote Configuration.

Intel® Rapid Start Technology

Intel® Rapid Start Technology allows quick system resumes from the hibernate state.

Intel® Platform Trust Technology (Intel® PTT)

Intel® Platform Trust Technology (Intel® PTT) is a platform functionality for credential storage and key management used by Windows 8* and Windows® 10. Intel® PTT supports BitLocker* for hard drive encryption and supports all Microsoft requirements for firmware Trusted Platform Module (fTPM) 2.0.

Intel® Trusted Execution Technology

Intel® Trusted Execution Technology for safer computing is a versatile set of hardware extensions to Intel® processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. It enables an environment where applications can run within their own space, protected from all other software on the system.
