3.4 Processor Function Overview

With the release of the Intel

Xeon

processor E5-2400 product family, several key system

components, including the CPU, Integrated Memory Controller (IMC), and Integrated IO Module

(IIO), have been combined into a single processor package and feature per socket; One Intel

QuickPath Interconnect point-to-point links capable of up to 8.0 GT/s, up to 24 lanes of Gen 3

PCI Express* links capable of 8.0 GT/s, and 4 lanes of DMI2/PCI Express* Gen 1 interface with

a peak transfer rate of 2.5 GT/s. The processor supports up to 46 bits of physical address space

and 48-bit of virtual address space.

The following sections will provide an overview of the key processor features and functions that

help to define the performance and architecture of the server board. For more comprehensive

processor specific information, refer to the Intel

Xeon

processor E5-2400 product family

documents listed in the Reference Document list.
