Ivy Bridge is the codename for Intel's 22 nanometre.for now This is the world's first chip 22 nanometre product and using '3D Transistor'.

Intel hasn't made such dramatic claims this time around as far as pure processor speed, but there are plenty of other improvements including eight-way Hyper-Threading, Turbo Boost 2.0, integrated USB 3.0, and native Thunderbolt support. The only two parts any mainstream consumer's likely to care about are the CPU gains and new Intel HD 4000 integrated graphics, which promise to greatly boost gaming performance without dedicated graphics.

-Max CPU multiplier of 63

-Tri gate transistor '3D'technology (up to 50% less power consumption at the same performance level as 2-D planar transistors)

Intel's 3-D Tri-Gate transistor uses three gates wrapped around the silicon channel in a 3-D structure, enabling an unprecedented combination of performance and energy efficiency. Intel designed the new transistor to provide unique ultra-low power benefits for use in handheld devices, like smart phones and tablets, while also delivering improved performance normally expected for high-end processors.

-PCI Express 3.0 support

-RAM support up to 2800 MT/s in 200 MHz increments

-Intel HD Graphics 2500/4000 with DirectX 11, OpenGL 3.1, and Open CL 1.1 support

-The built-in GPU will have 6 or 16 execution units (EUs)

-A new random number generator and the RdRand instruction

-DDR3L and Configurable TDP for mobile processors

-Multiple 4K video playback
