HumanSmoke Aye, and it will be interesting to see what the clock envelope is for the gaming/prosumer parts. 12gb running at 6600M effective must chew through at least a third of the power budget for a workstation card (assuming ~250W board power)

(and I didn't even mention cost....even though I think 290/290x clearly show a trend for the way forward in AMD's future price structure...which will lead to inevitable 980 price drops and higher-end chips taking it's place.)

According to my math, that sounds about right. :toast:So (if this is true) figure a core clock roughly 20-25% higher or so (real/'boost'/load), which more-or-less meshes with the earlier rumors.I have to imagine the default clock (for consumer parts) is fluid dependent upon whatever Fiji/whatever is comparably, but I don't doubt that earlier-reported 1100n/1390b (overclocked?) is within reason for 300w.I've always figured this arch was engineered with 20nm in mind (which obviously nvidia backed out of at some point, probably not long after they threw that hissy-fit presentation about tsmc's 20nm cost) and the clocks vs older archs reflect that. IOW, 1100 is probably the new '~900mhz' and 1390 the new 11xx (think 1.163-1.175ish volts for both companies earlier products). It meshes with one of nvidia's chief scientists that said 20nm gave a 20-25% boost.Extrapolate as we may, we still prolly have a ways to go before any hard numbers that could truly give an indication of where it (or the competition) will end up.The only thing one can safely say is 980 is meant to preempt a faster iteration of a 290x-like product, and a higher segment is typically around 15-20% faster.From there, each company *should* have two more products on new chips that climb two more approx similar steps, while obviously each lower chip generally overclocks to the level of the stock next level.If you take that to it's logical conclusion assuming 21 and 24 SMM parts that (over)clock slightly lower (~90%?) than GM204 counterparts (due to extra ram etc), I think it gels...but that's pure speculation.
