Intel Corp. said on Tuesday that it began mass production of code-named Ivy Bridge central processing units (CPUs) using 22nm process technology in the third quarter of this year. The initialization of production at 22nm node not only ensures Intel's ability to continue driving performance of computer chips upwards every year, but confirms the company's production technology leadership.


"During the third quarter, we began volume production of Ivy Bridge on our 22nm process technology. 22nm will usher-in the era of 3D transistors, which will pay dividends in power, performance and density for generations to come," said Paul Otellini, chief executive officer of Intel, during a conference call with financial analysts.

According to Intel, the 22nm 3D tri-gate transistors provide up to 37% performance increase at low voltage versus Intel's 32nm planar transistors, which means that operating voltage and thus power consumption can be further reduced with present levels of performance.

Ivy Bridge will generally inherit Sandy Bridge micro-architecture and will sport a rather significant number of improvements. Firstly, it will have certain improvements that will boost its performance in general applications by around 20% compared to Core i "Sandy Bridge" chips (e.g., enhanced AVX acceleration). Secondly, the forthcoming chip will have a new graphics core with DirectX 11 and OpenCL 1.1 support, 30% higher performance compared to the predecessor as well as new video processor and display controllers. Thirdly, Ivy Bridge will feature PCI Express 3.0 x16 interconnection as well as PCIe 2.0 x4 controller. In fourth, the processor will support a number of power management innovations. The CPU is made using 22nm process technology.

Intel will release its code-named Ivy Bridge central processing units for desktops in March or April, 2012.
