Details have emerged about Intel's upcoming Medfield chip platform for smartphones, which is due for release in 2011 and will succeed the company's existing Moorestown platform, which was originally announced in May.

The Medfield platform will include a power-efficient version of the Atom processor, which will be integrated inside a chip code-named Penwell, according to a document originally posted on Intel's website, which is still available on Google cache.

In a separate document on its website dated Aug. 9, Intel has also hinted at some of Penwell's Atom-based microprocessors running at speeds of 1.80GHz and 1.86GHz. Current CPUs in the Moorestown platform chips -- also called the Z600-series chips -- can run at up to 1.5GHz for smartphones and up to 1.9GHz for tablets.

Intel spokeswoman Claudine Mangano declined to comment on details surrounding the Medfield chips.
