[Why Apple would be absolutely crazy not to consider Intel's vastly superior fabrication...]
Could we have 5nm by 2015?
Digitimes has claimed that Intel's process of shrinking its manufacturing process to 14nm is right on schedule and that the new hardware is still expected to be with us some time within the next 12 months or so. The obvious benefits of this will be more powerful chips, lower power consumption and more, but 12 months is a long time to wait in this industry and we'll have to wait and see what offerings Intel has lined up for us.
On to of that its now believed that Intel will have got the process down to 5nm by 2015! where are Globalfoundries plans to have its 14nm FinFET complete within the same time frame, either way things are about to get into the even crazier scale of tiny.
Intel are making great advances at the moment, something the developers at Samsung and TSMC will be well aware of as they face being left behind the pack, especially since they plan to ship 18" wafers some time in 2017.
Intel is already looking to expand its plants in Oregon, Arizona and Ireland which will no doubt help them push out further 14nm CPUs and Socs throughout 2013 before we hit the 10nm, 7nm and 5nm process in the run up to 2015-17.
