BAD HARDWARE WEEK

As far as product launches are concerned, we can expect a launch date of the new products based upon the TSMC 20nm and GLOFO 14nm FinFET processes by late 2014 or early 2015 since they are only currently being tapped out.

After all, ARM is expected to move from 28nm to 20nm fabrication on the Cortex-A15 and 64-bit, ARMv8 Cortex-A57 designs by 2014. The micro-server and desktop-targeted A57 will support a big.LITTLE arrangement with the similarly ARMv8-based Cortex-A53 smartphone/tablet SoC. Both should advance to 14nm fabrication by 2015 or 2016.

99% BAD HARDWARE WEEK: However AMD's 14nm XM  FinFET SOI technology doesn't seem like a Intel's 14 nm vaporware by the end of this year. If tic toc still works.
The 14XM FinFET node is a low power product aimed at mobile applications at 14 nm.  It will not be a good choice for large, power hungry products like GPUs, but it will be appropriate for low power SOCs. 
I fully expect to see ARMv8 based processors utilize this node.
