Intel Ivy Bridge–based Xeon microprocessors (also known as Ivy Bridge-E) is the follow-up to Sandy Bridge-E, using the same CPU core as the Ivy Bridge processor, but in LGA 2011, LGA 1356 and LGA 2011-1 packages for workstations and servers.

There are five different families of Xeon processors that were based on the Ivy Bridge architecture:

Ivy Bridge-E uses LGA 2011 socket and was branded as Core i7 Extreme Edition and Core i7 high-end desktop (HEDT) processors, despite sharing many similarities with Xeon E5 models. Ivy Bridge-EP which also uses LGA 2011 socket for the Xeon E5 models aimed at high-end servers and workstations. It supports up to 4 socket motherboards. Ivy Bridge-EX introduces new LGA 2011-1 socket and features up to 15 cores. It supports up to eight socket motherboards. Ivy Bridge-EN uses a smaller LGA 1356 socket for low-end and dual-processor servers on certain Xeon E5 and Pentium branded models. Ivy Bridge Xeon with LGA 1155 socket were mostly identical to its desktop counterparts apart from the missing IGPU despite branded as Xeon processors. Gladden was offered in BGA 1284 package for embedded applications.

Features

Dual memory controllers for Ivy Bridge-EP and Ivy Bridge-EX Up to 12 CPU cores and 30 MB of L3 cache for Ivy Bridge-EP Up to 15 CPU cores and 37.5 MB L3 cache for Ivy Bridge-EX (released on February 18, 2014 as Xeon E7 v2) Thermal design power between 50 W and 155 W Support for up to eight DIMMs of DDR3-1866 memory per socket, with reductions in memory speed depending on the number of DIMMs per channel No integrated GPU Ivy Bridge-EP introduced new hardware support for interrupt virtualization, branded as APICv.

Models and steppings The basic Ivy Bridge-E is a single-socket processor sold as Core i7-49xx and is only available in the six-core S1 stepping, with some versions limited to four active cores.

There are in fact three die "flavors" for the Ivy Bridge-EP, meaning that they are manufactured and organized differently, according to the number of cores an Ivy Bridge-EP CPU includes: The largest is an up-to-12-core die organized as three four-core columns with up to 30 MB L3 cache in two banks between the cores; these cores are linked by three rings of interconnects. The intermediate is an up-to-10-core die organized as two five-core columns with up to 25 MB L3 cache in a single bank between the cores; the cores are linked by two rings of interconnects. The smallest is an up-to-six-core die organized as two three-core columns with up to 15 MB L3 cache in a single bank between the cores; the cores are linked by two rings of interconnects.

Ivy Bridge-EX has up to 15 cores and scales to 8 sockets. The 15-core die is organized into three columns of five cores, with three interconnect rings connecting two columns per ring; each five-core column has a separate L3 cache.
