Theo Valich from Bright Side of News claims Nokia is collaborating with Intel to develop custom silicon based on the x86 architecture for future smartphones and phones:
We were aware of negotiations Nokia had with ARM vendors such as Texas Instruments [Nokia is one of - if not the largest TI customer], Qualcomm and nVidia, but not a single company didn't want the level of partnership and design influence Nokia wanted, yet this phonezilla wanted to have much more interactive relationship than it has with its current silicon vendors. Intel agreed on many interesting requirements from Nokia. We got some highlights from the Nokia-Intel cooperation and they're quite interesting - for instance, Intel views Nokia in the same way as a Microsoft-Intel axis resulted in "Wintel" agreement. This time around, the new battleground are phones and Intel sees a large opportunity.
