3.2 Processor Functions Overview
With the release of the Intel® Xeon® processor E5-4600 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; two Intel
®
QuickPath Interconnect point-to-point links
capable of up to 8.0 GT/s, up to 40 lanes of Gen 3 PCI Express* links capable of 8.0 GT/s, and 4 lanes of
DMI2/PCI Express* Gen 2 interface with a peak transfer rate of 5.0 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 E5-4600 product family documents listed in the Reference Document list
at the end of this specification.
