*** AMD "Zen" thread (inc AM4/APU discussion) ***

Seeing how semiconductor companies are now using lower numbers to denote performance instead of actual size, I'm guessing this 12nm is actually just an improved version of their 14nm? They compared it to a competitor's 16nm instead of their first 14nm LPP...

Most likely but looking at the bumpf it should mean higher clockspeeds.

Is that what was getting referred to as Vega and Ryzen+

Well at a 10% increased clock speed on just a straight 1 to 1 shrink that will be mid 4Ghz.

I was basing on the fact that 3.9GHz all-core seems to be the most common overclock for gen1 Ryzens, 10% on top of that would be 4.29GHz, so if the majority could hit a reliable 4.2+ that's a decent improvement, and totally reasonable taking that those top slice Threadrippers are commonly hitting 4.1+ on the current fab.
 
Yea. This was one of the reasons I went AM4. I'll upgrade the 1700 with the last AM4 compatible chip in a couple of years.

Probably only then need to add another 16Gb of ram and sorted for another 3-4 years. (GPU upgrade permitting)

I'm hoping by that time we have AM4 compatible chips greater than 8core /16thread.

Well the XFR chips are 4-4.1Ghz stock.

Any core can run those types of speeds though.

At very high volts well outside of the efficiency range of the fab process yeah. No doubt everyone could get 4GHz if you were willing to pump the XFR 1.5V+ through your CPU constantly. Realistic all core speeds are 3.9 at reasonable volts. With the fab update that all core speed should shuffle up a few notches while remaining in the 'reasonable' voltage range.
