TSMC shows off a 28nm ARM -

TSMC has started rolling out a 28-nanometer ARM chip which can run at 3.1GHz.

As CNET has pointed out, this is pretty fast for a mobile chip and while Intel's higher-end mobile parts are rated close to 3GHz they suck up more juice and are more expensive.

The TSMC chip is a dual-core A9 managed to do its speed feat under under typical conditions. In other words, in a machine and not sitting in a bucket of liquid nitrogen.

TSMC said that its 28-nanometer HPM process was developed for tablet and mobile consumer products. It claims that it's twice as fast as an equivalent chip built on an older 40nm process.

Using scalable design conditions, ARM A9 at TSMC 28HPM delivers performance speed ranging from 1.5GHz to 2.0GHz and to 3.1GHz, the company said.

Cliff Hou, TSMC Vice President, Research & Development said that the work demonstrates how ARM and TSMC can satisfy high performance market demands.

There is no indication where the chip will end up, or if TSMC has any clients for it.
