Ivy Bridge (microarchitecture)
Ivy Bridge is the codename for Intel's 22 nm die shrink of the Sandy Bridge microarchitecture. Intel plans to release CPUs based on the design for retail sale in 2012. Ivy Bridge processors will be backwards-compatible with the Sandy Bridge platform, but require a BIOS/firmware update.[1][2] Intel also plans a new 7-series Panther Point chipsets with Ivy Bridge that will come with integrated USB 3.0.[3]
With no significant obstacles during production of the new tri-gate ("3D") transistor, Intel planned to begin sale of the processors to middlemen in the last quarter of 2011,[4] with retail availability from April 2012,[5] and one source specifying April 8.[6] Intel announced production of Ivy Bridge chips in volume, in preparation for the product launch, starting in the third quarter of 2011.[7][8] The successor to Ivy Bridge is the Haswell microarchitecture, planned to be released in 2013.[9]
Technology
Ivy Bridge feature improvements from Sandy Bridge were expected to include:[10][11]
Thermal design power (TDP), according to a October 2011 leaked Intel roadmap, will come in 77/65/55/45/35W options for desktop processors,[17] while Intel says that mobile processors will use variable TDP (for example TDP of 15W, which automatically rises to 35W when the laptop is plugged into a docking bay; with a corresponding rise in performance).[18]
Performance
Intel's performance targets (compared to Sandy Bridge):[19]
- Up to 20% increase in CPU performance.
- Up to 30% increase in integrated GPU performance.
