Overview

Home snoop based coherency

3-bit Node ID

46-bit physical addressing support

No Intel QuickPath Interconnect bifurcation support

Differential signaling

Forwarded clocking

Up to 8.0 GT/s data rate (up to 16 GB/s direction peak bandwidth per port)

All ports run at same operational frequency

Reference Clock is 100 MHz

Slow boot speed initialization at 50 MT/s

Common reference clocking (same clock generator for both sender and receiver)

Intel® Interconnect Built-In-Self-Test (Intel® IBIST) for high-speed testability

Polarity and Lane reversal (Rx side only)

1.2.5Platform Environment Control Interface (PECI)

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

Supports operation at up to 2 Mbps data transfers

Link layer improvements to support additional services and higher efficiency over PECI 2.0 generation

Services include CPU thermal and estimated power information, control functions for power limiting, P-state and T-state control, and access for Machine Check Architecture registers and PCI configuration space (both within the processor package and downstream devices)

PECI address determined by SOCKET_ID configuration

Single domain (Domain 0) is supported
