At this year’s TechCon 2017, ARM announced that it is extending its partnership with Intel’s foundry business to build IP tailored for the x86 giant’s 22nm FinFET node. It’s a fascinating example of co-opetition from the processor rivals. ARM will deliver IP to enable a Cortex-A55 geared for midrange smartphones to run up to 2.35 GHz or down to 0.45V in its so-called 22FFL process.



ARM is already helping make in Intel’s flagship 10nm process a test chip due out before the end of the year using a next-gen Cortex-A SoC running at 3.5 GHz or 0.5V and delivering 0.25mW/MHz. Observers said the level of candor was new for Intel but key to establishing a foundry business it has been struggling — largely with its own culture — to stand up for years.
