Name

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 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.

PCI Express Configurations

PCI Express (PCIe) Configurations describe the available PCIe lane configurations that can be used to link 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. Max # of PCI Express Lanes is the total number of supported lanes.

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.
