Is this simply Intel getting itself into focus or are they missing out on a mobile opportunity with this sale?

Intel will sell its XScale PXAxxx applications processor and 3G baseband processor businesses to Marvell for $600 million, plus existing liabilities. The deal could make Marvell the top supplier of 3G and later smartphone processors, and enable Intel to focus on its core x86 and wireless LAN chipset businesses, the companies say.

Intel competitor AMD earlier this month divested itself of its non-x86-based Alchemy processor line, selling it to Raza Microelectronics for an undisclosed sum.

The Marvell deal does not affect Intel’s XScale-based IXPxxx and IXPxxxx network processor lines, nor its XScale-based IOPxxx storage processor line. In addition to PXA-series applications processors, the deal does include Intel’s baseband processors for UMTS, HSDPA, and other 3, 3.5, and 4G mobile phone technologies…. Source: Linux Devices
