What doom and gloom? All I hear about Zen is solid clocks for an 8c part (3.8Ghz+ for MT loads) plus accurate and flexible power management. Except for power consumption at high clocks (4Ghz+) which many prefer to approach in a more cautious manner, Ryzen looks like a great CPU. Not ok, not good enough, but great. In marketing speech that would translate to freaking spectacular.
Even if the top 3.6/4Ghz part ends up being a ~120W TDP part like CPC Hardware suggests, the only fault Zen appears to have is obeying the laws of physics. At this point all I'm interested to find out about Zen is pricing and performance consistency. Frequency and power are no longer a curiosity, except maybe in relation to max oc numbers.
I don't know if AMD was hiding very well at new horizon event or the ES shown was the best that AMD can produce. Worst case is 3.4GHz@95W. We don't have true proof of higher frequencies. Only speculations on solid data as I have done here. But something could go wrong. Yield can be low. Process variation can be high. I am not sure that Zen can reach those theorethical frequencies in the first batches.
