They may be a little gunshy about that kind of thing now. Half the threads about fx 9590's here come down to mobo issues. Either boards that don't officially support it but sorta work anyway, or boards that are supposed to support it and burn out their power delivery systems. It shouldn't be the same situation given the power usage disparity will be much less, or even negative, but there isn't a lot of information about the 12nm LP node as of yet.
Juanrga and Jdwii said they seen on other forums that the talk is lower operating voltage, which they assume ~3-400MHz boost to frequency. But they are still seeing limitation with a frequency wall 4.1GHz.
Those aren't my words.
I take it back than. What were you saying?
