Introduction
The Intel® Xeon® processor E5-1600/E5-2600/E5-4600 product families are the next generation of 64-bit, multi-core enterprise
processors built on 32-nanometer process technology. Throughout this document, the Intel® Xeon® processor E5-1600/E5-
2600/E5-4600 product families may be referred to as simply the processor. Where information differs between the EP and EP 4S
SKUs, this document uses specific Intel® Xeon® processor E5-1600 product family, Intel® Xeon® processor E5-2600 product family,
and Intel® Xeon® processor E5-4600 product family notation. Based on the low-power/high performance 2nd Generation Intel® Core™
Processor Family microarchitecture, the processor is designed for a two chip platform consisting of a processor and a Platform
Controller Hub (PCH) enabling higher performance, easier validation, and improved x-y footprint. The Intel® Xeon® processor E5-1600
product family and the Intel® Xeon® processor E5-2600 product family are designed for Efficient Performance server, workstation and
HPC platforms. The Intel® Xeon® processor E5-4600 product family processor supports scalable server and HPC platforms of two or
more processors, including "glueless" 4-way platforms.
NOTE: some processor features are not available on all platforms.
These processors feature per socket, two Intel® QuickPath Interconnect point-to-point links capable of up to 8.0 GT/s, up to 40 lanes
of PCI Express* 3.0 links capable of 8.0 GT/s, and 4 lanes of DMI2/PCI Express* 2.0 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.
Included in this family of processors is an integrated memory controller (IMC) and integrated I/O (IIO) (such as PCI Express* and DMI2)
on a single silicon die. This single die solution is known as a monolithic processor.
