Name

Supported FSBs

FSB (Front Side Bus) is the interconnect between the processor and the Memory Controller Hub (MCH).

FSB Parity

FSB parity provides error checking on data sent on the FSB (Front Side Bus).

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.

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.

Max Memory Size (dependent on memory type)

Max memory size refers to the maximum memory capacity supported by the processor.

Memory Types

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.

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

Graphics Output defines the interfaces available to communicate with display devices.

Intel® Clear Video Technology

Intel® Clear Video Technology is a suite of image decode and processing technologies built into the integrated processor graphics that improve video playback, delivering cleaner, sharper images, more natural, accurate, and vivid colors, and a clear and stable video picture.

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.

TCASE

Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).

Intel® Fast Memory Access

Intel® Fast Memory Access is an updated Graphics Memory Controller Hub (GMCH) backbone architecture that improves system performance by optimizing the use of available memory bandwidth and reducing the latency of the memory accesses.

Intel® Flex Memory Access

Intel® Flex Memory Access facilitates easier upgrades by allowing different memory sizes to be populated and remain in dual-channel mode.
