Datasheet, Volume 1

• 64-bit downstream address format; however, the processor never generates an 

address above 64 GB (Bits 63:36 will always be zeros)

• 64-bit upstream address format, but the processor responds to upstream read 

transactions to addresses above 64 GB (addresses where any of Bits 63:36 are 
nonzero) with an Unsupported Request response. Upstream write transactions to 
addresses above 64 GB will be dropped.

• Supports the following traffic types to or from the PCH:

— DMI  ->  DRAM

— DMI -> processor core (Virtual Legacy Wires (VLWs), Resetwarn, or MSIs only)

— Processor core -> DMI

• APIC and MSI interrupt messaging support:

— Message Signaled Interrupt (MSI and MSI-X) messages

• Downstream SMI, SCI and SERR error indication
• Legacy support for ISA regime protocol (PHOLD / PHOLDA) required for parallel 

port DMA, floppy drive, and LPC bus masters

• DC coupling – no capacitors between the processor and the PCH
• Polarity inversion
• PCH end-to-end lane reversal across the link
• Supports Half Swing “low-power / low-voltage”

The PECI is a one-wire interface that provides a communication channel between a 
PECI client (the processor) and a PECI master. The processor supports the PECI 3.0 
Specification.

• The Processor Graphics contains a refresh of the seventh generation graphics core 

enabling substantial gains in performance and lower power consumption. Up to 
16 EU support.

• Next Generation Intel Clear Video Technology HD Support is a collection of video 

playback and enhancement features that improve the end user’s viewing 
experience

— Encode / transcode HD content
— Playback of high definition content including Blu-ray Disc*
— Superior image quality with sharper, more colorful images
— Playback of Blu-ray disc S3D content using HDMI (V.1.4 with 3D)

• DirectX* Video Acceleration (DXVA) support for accelerating video processing

— Full AVC/VC1/MPEG2 HW Decode

• Advanced Scheduler 2.0, 1.0, XPDM support
• Windows* 7, Windows* XP, OSX, Linux OS Support
• DirectX* 11, DirectX* 10.1, DirectX* 10, DirectX* 9 support
• OpenGL* 3.0 support
