Intel® Xeon® Processor E7 v3 Product Family

Based on Intel® Core™ microarchitecture (formerly codenamed Haswell) and manufactured on 22-nanometer process technology, these processors provide significant performance over the previous-generation Intel Xeon processor E7 v2 product family. This is the first Intel® Xeon® processor product family that supports Intel® Transaction Synchronization Extensions (Intel® TSX).

For a more in-depth discussion of the key features and the architecture of the Intel® Xeon® E7 v3 product family see the technical overview document.

Key supported features you should be aware of, as a Software Developer:

  • Intel® Virtual Machine Control Structure (Intel® VMCS) Shadowing works by reducing the frequency in which the guest virtual machine monitor (VMM) requires assistance from the parent VMM. Its goal is to eliminate the VM-exits due to VMREAD and VMWRITE instructions executed by the guest VMM. The Intel and Citrix collaboration article provides a good description about the benefit of using Intel® VMCS shadowing.  A team at IBM® enabled this feature and gained significant performance improvement.
  • New Reliability features include Enhanced Machine Check Architecture Generation 2 (eMCA2).  Prior to eMCA2, errors were logged in architected registers and OS/VMM (Virtual Machine Management) was informed.  This will restrict the platform firmware from doing fault diagnosis. eMCA2 allows errors (corrected and uncorrected) to first signal the BIOS/SMM(System Management Mode) before determining if the errors need to be informed to the OS/VMM . Another important reliability feature is Memory Address Range Mirroring (MARM). MARM allows the BIOS or OS to determine a range of memory addresses to be mirrored instead of mirroring the entire memory space.  More information about these features can be found here
