The last I heard about them was April 2015. Are they going to be released?
There may not be any FM3 CPUs. The only reference to an FM3 socket / CPU processors that I am aware of was a bogus AMD road map/stories that someone had photo shopped. The Zen CPUs are scheduled to use socket AM4. Zen based APUs are scheduled to use the FP4 socket? Zen desktop CPUs are expected in Q4 of this year. Zen core APUs might also be available this year but definitely in 2017.
