The Intel processor number is just one of several factors—along with processor brand, system configurations, and system-level benchmarks—to be considered when choosing the right processor for your computing needs. Read more about interpreting Intel® processor numbers or Intel® processor numbers for the Data Center.
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.
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)*.
Cores is a hardware term that describes the number of independent central processing units in a single computing component (die or chip).
Where applicable, Intel® Hyper-Threading Technology is only available on Performance-cores.
Processor Base Frequency
Processor Base Frequency describes the rate at which the processor's transistors open and close. The processor base frequency is the operating point where TDP is defined. Frequency is typically measured in gigahertz (GHz), or billion cycles per second.
CPU Cache is an area of fast memory located on the processor. Intel® Smart Cache refers to the architecture that allows all cores to dynamically share access to the last level cache.
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.
Max Memory Size (dependent on memory type)
Max memory size refers to the maximum memory capacity supported by the processor.
Intel® processors come in four different types: Single Channel, Dual Channel, Triple Channel, and Flex Mode. Maximum supported memory speed may be lower when populating multiple DIMMs per channel on products that support multiple memory channels.
Max # of Memory Channels
The number of memory channels refers to the bandwidth operation for real world application.
Max Memory Bandwidth
Max Memory bandwidth is the maximum rate at which data can be read from or stored into a semiconductor memory by the processor (in GB/s).
Physical Address Extensions
Physical Address Extensions (PAE) is a feature that allows 32-bit processors to access a physical address space larger than 4 gigabytes.
ECC Memory Supported ‡
ECC Memory Supported indicates processor support for Error-Correcting Code memory. ECC memory is a type of system memory that can detect and correct common kinds of internal data corruption. Note that ECC memory support requires both processor and chipset support.
Graphics Base Frequency
Graphics Base frequency refers to the rated/guaranteed graphics render clock frequency in MHz.
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.
The socket is the component that provides the mechanical and electrical connections between the processor and motherboard.
Junction Temperature is the maximum temperature allowed at the processor die.
Intel® Turbo Boost Technology ‡
Intel® Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it, and increased energy efficiency when you don’t.
Intel® Hyper-Threading Technology ‡
Intel® Hyper-Threading Technology (Intel® HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner.
Intel® 64 ‡
Intel® 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software.¹ Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.
An instruction set refers to the basic set of commands and instructions that a microprocessor understands and can carry out. The value shown represents which Intel’s instruction set this processor is compatible with.
Instruction Set Extensions
Instruction Set Extensions are additional instructions which can increase performance when the same operations are performed on multiple data objects. These can include SSE (Streaming SIMD Extensions) and AVX (Advanced Vector Extensions).
Enhanced Intel SpeedStep® Technology
Enhanced Intel SpeedStep® Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep® Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep® Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.
Intel® Virtualization Technology for Itanium (VT-i)
Intel® Virtualization Technology for Itanium (VT-i) allows one Intel® Itanium® Processor platform to function as multiple “virtual” platforms. Offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions.
Intel vPro® Platform Eligibility ‡
The Intel vPro® platform is a set of hardware and technologies used to build business computing endpoints with premium performance, built-in security, modern manageability and platform stability.

Intel® Virtualization Technology (VT-x) ‡
Intel® Virtualization Technology (VT-x) allows one hardware platform to function as multiple “virtual” platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions.
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 ships these processors to Original Equipment Manufacturers (OEMs), and the OEMs typically pre-install the processor. Intel refers to these processors as tray or OEM processors. Intel doesn't provide direct warranty support. Contact your OEM or reseller for warranty support.
