10 nm
In 2017, ARM announced that it had completed the world's first chip flow sheet based on 10nm process in cooperation with TSMC, and used the top new architecture \"Artemis\" that has not yet been announced. The new process used by TSMC here is the 10nm version, which claims that the transistor integration is up to 2.1 times higher than that of 16nm. You can also get an 11-12% performance improvement or a 30% reduction in power consumption at the same frequency.
