A 22nm update to [[Sandy Bridge]], scheduled for release in late 2012. This will be the first chip to feature Intel's new "FinFET" [http://en.wikipedia.org/wiki/Multigate_device#Tri-gate_transistors_.28Intel.29 trigate] nonplanar transistor technology. Its Panther Point chipset is expected to support [[PCIe|PCIe 3.0]], while the IGD will add DirectX 11 and [[OpenCL|OpenCL 1.1]] support.

Ivy Bridge is expected to continue making use of the LGA1155 socket interface introduced with Sandy Bridge.

* The [[RDRAND]] instruction is made available on Ivy Bridge processors containing Bull Mountain hardware.

* Supervisory Mode Execution Protection (SMEP) prohibits ring 0 code from executing memory writable by other rings

==Microarchitecture==

Microarchitecture is expected to be similar to that of [[Sandy Bridge]].

==~~Chipset~~==

==Branding/Differentiation==

==Processor Support==

Ivy Bridge will introduce the "Panther Point" 7-series PCH (Platform Controller Hub), and the second-tier "Patsburg" X79 (this latter will use DMI rather than QPI). Native USB 3.0 and [[PCIe|PCIe 3.0]] support is expected on-chip.
