I think if Vishera doesn't deliver past Phenom II performance in both single and multi-threaded situations. That AMD will lose 90% of its enthusiast market to Intel. Who in their right mind will pay $250 for a processor that can't beat a $219 i5. I know this much im trying to get away from AMD but its hard because of the prices of Intel's products.
You do realize Zambezi does offer similar to PhII performance when overclocked in the real world, right? Sure, benchmarks might show PhII being ahead but those are just benchmarks...

Unless Resonant Clock Mesh is the greatest thing since sliced bread, it's pretty naive to assume Vishera will clock higher than Zambezi.
Leakage makes for good LN2 chips, I imagine that won't go too much higher for PD but high leakage chips are bad for clocking on air and water because temperatures and voltages often limit you, my CPUs a fairly leaky one afaik (1.4v stock) and it can't hit over 4.5Ghz stable.
CPU-z of highest stable clocks, the IMC is screwed so that's about as fast as I can get my RAM despite it being 1866Mhz CL9 sticks.

Absolutely, RCM does wonders for power consumption and thermal envelopes...doesn't mean max overclocks will be higher.
I'm just saying this so the people who assume their Piledriver will overclock to 5.0Ghz on air guaranteed don't point fingers at AMD for speculation they themselves created.
Some BDs OC to 5Ghz on air, so I think it's safe to assume some PDs will.
Anyway, aren't a tonne of BD overclocks limited by voltage or heat? RCM would help with heat and I'd imagine some of the other optimisations (And the maturing of the 32nm process) would help with voltage, I can see it not really hitting much higher than BD max (If any higher at all) on air and water, but the average OC being higher. (So instead of having so many chips limited to 4.5Ghz or so, you'd have the lower-end ones hitting 4.8Ghz). Obviously that's all speculation, though.

As we get closer to channel availability, we have to guess that platform vendors will better-optimize the overclocking headroom of K-series SKUs, particularly since there will be three of them at launch.
RCM
could be the best thing since sliced bread.
That Trinity sample is similar to my Zambezi, although mine seems to be mostly stable in Windows up until 4.8Ghz, with a bit less voltage.
Although I'd imagine that they weren't trying
really hard for optimisation with voltage, etc as I have.
