Hello everyone, first post. Some of you may know me from XtremeSystems, or HWBOT.
I think the bickering about power delta and performance per watt is happening a little early, and you all seem very heated on the subject.
Typical CPU package power is most certainly not 0w: 2-15w are common depending on P-State, slight load variance (a background process could cause the CPU to switch in and out of its lowest P-State), etc. Your laptop can most certainly run all day when the CPU is only sipping 3w, but when it is eating 30w, not so much.
As far as the talk about idle-load deltas and platform power, the platform is what matters most. Not to say the individual CPU power consumption isn't important, but total platform power is what matters, not only in HEDT / desktop, but more importantly laptop / mobile. The goal of reducing total platform power at both idle and load is the reason we see more and more functions that were previously handled by northbridge / southbridge being integrated into the CPU die in the first place.
I think the most important thing to remember here is that AMD was so far behind, even with XV, that even getting close to Bdw-E is quite an achievement. To those speculating 4.2+ turbo speeds, I don't think AMD is quite there yet. I'm guessing 3.7 to 4.0 turbo, personally.
So TL;DR to remember relating to power consumption as we head toward launch:
Idle CPUs more than zero watts, but this number can still be low, in the 2-5w range. Mobile CPUs usually less due to more aggressive clock / voltage reduction
TDP is thermal design power or thermal design point - NOT indicative of power consumption, though we often relate it to power consumption
Total platform power is key for end users, though it is neat to see CPU only power consumption
Ryzen is likely to be priced cheaper than Intel's HEDT solutions
GloFo's 14nm process is likely not as good as Intel's 14nm or 14nm+, I suspect gate pitch, fin pitch, and metal pitch all to be 10-15% higher than intel's. For intel's 14nm+ there are many news sites that claimed the gate pitch was actually wider, but no source was listed
