There will be a second launch of Core chips later this year in which dual-core Ivy Bridge processors will be launched for mainstream laptops, Intel CEO Paul Otellini said during an earnings call.

PCs with the new quad-core chips will be announced shortly after the chip launch, Otellini said.

Otellini did not say when specific Ivy Bridge chips for ultrabooks would be released. However, several ultrabook models with Ivy Bridge processors have already been announced, and some models are due to ship in the coming months.

Many PCs shipping today have second-generation Core processors code-named Sandy Bridge. Intel has said it will launch the third-generation Core processors based on Ivy Bridge next week, but until now it had not specified which chips would be announced.

There is a strong demand for desktops, especially in emerging markets, Otellini said. The company had to delay the Ivy Bridge launch by a few weeks to ensure it had enough inventory for the PC launches.
