Drivers and Software
The date the product was first introduced.
Lithography refers to the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometer (nm), indicative of the size of features built on the semiconductor.
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.
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.
Integrated Graphics ‡
Integrated graphics allow for incredible visual quality, faster graphic performance and flexible display options without the need for a separate graphics card.
Graphics Output defines the interfaces available to communicate with display devices.
PCI support indicates the type of support for the Peripheral Component Interconnect standard
PCI Express Revision
PCI Express Revision is the supported version of the PCI Express standard. 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.
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. Max # of PCI Express Lanes is the total number of supported lanes.
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 indicates the presence of an integrated Intel Ethernet MAC or presence of the LAN ports built into the system board.
Intel® ME Firmware Version
Intel® Management Engine Firmware (Intel® ME FW) uses built-in platform capabilities and management and security applications to remotely manage networked computing assets out-of-band.
Intel® Remote PC Assist Technology
Intel® Remote PC Assist Technology enables you to request remote technical assistance from a service provider if you encounter a problem with your PC, even when the OS, network software, or applications are not functioning. This service was discontinued in October 2010.
Intel® Quick Resume Technology
Intel® Quick Resume Technology Driver (QRTD) allows the Intel® Viiv™ technology-based PC to behave like a consumer electronic device with instant on/off (after initial boot, when activated) capability.
Intel® Quiet System Technology
Intel® Quiet System Technology can help reduce system noise and heat through more intelligent fan speed control algorithms.
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® AC97 Technology
Intel® AC97 Technology is an audio codec standard which defines a high-quality audio architecture with surround sound support for the PC. It is the predecessor to Intel® High Definition Audio.
Intel® Matrix Storage Technology
Intel® Matrix Storage Technology provides protection, performance, and expandability for desktop and mobile platforms. Whether using one or multiple hard drives, users can take advantage of enhanced performance and lower power consumption. When using more than one drive the user can have additional protection against data loss in the event of hard drive failure. Predecessor to Intel® Rapid Storage Technology
