Launch Date

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.

Max Operating Temperature

This is the maximum operating temperature allowed as reported by temperature sensors. Instantaneous temperature may exceed this value for short durations. Note: Maximum observable temperature is configurable by system vendor and can be design specific.

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 the SKU is typically available for purchase for 7 years from the launch of the first SKU in the Product family and may be available for purchase for a longer period of time under certain circumstances. Intel does not commit or guarantee product Availability or Technical Support by way of roadmap guidance. Intel reserves the right to change roadmaps or discontinue products, software and software support services through standard EOL/PDN processes. Product certification and use condition information can be found in the Production Release Qualification (PRQ) report for this SKU. Contact your Intel representative for details.

IEEE 1588

IEEE 1588, also knows as the Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems.
