The Processor Architecture
Overview
This section describes the key architecture features of the core and uncore modules of
the Intel Xeon processor E7 v2 product family.
the Intel Xeon processor E7 v2 product family.
shows a high level view of the processor integrating:
• Multiple Intel Xeon processor E7-2800/4800/8800 v2 product family cores
• Up to 3 Intel QPI interfaces
• Up to 32 PCI Express* 3.0 lanes
• 1 x4 DMI2/PCIe* 2.0 interface
• Up to 3 Intel QPI interfaces
• Up to 32 PCI Express* 3.0 lanes
• 1 x4 DMI2/PCIe* 2.0 interface
For the purpose of architectural description, the processor can be sub-divided into
three main areas - core, uncore, and IIO. “Core” includes Intel Xeon processor E7 v2
product family core. Uncore includes Last Level Cache (LLC), Caching agents (Cbo),
Home Agent (HA), Ring to Intel QPI blocks (R3QPI), Intel QPI Agents, integrated
memory controller (iMC), Power Control Unit (PCU), Configuration Agent (Ubox), and
the IIO module.
