I'm sorry but you are wrong, and here is why: Piledriver is based on the same faildozer design and thus will NOT work right on anything but Windows 8, and as we have seen the backlash on win 8 is gonna be insane. its like designing a chip that works best with WinME, its practically suicide.
The problem is Faildozer was originally envisioned as "The GPU does the FP with a weaker FP shared between cores for when gaming" now we can already see the problem, yes? windows cheduler, thanks to AMD not keeping them in the loop, doesn't have a clue how to treat the "one FP for two cores" design so what you get is a bad hardware assisted HyperThreading. this is why a Thuban, which has a FP per core, stomps the new design in most benches.
While the "GPU does the FP" is an interesting idea in theory, as we all know theory and practice are two different things. For that to work either AMD is gonna have to get everyone to code for it (not likely) or AMD is gonna have to seamlessly offload the FP code to the GPU with enough cache and speed that it doesn't take a penalty. Now as much as i support AMD, in fact every machine I've built for the past 5 years and my own family's machines are ALL AMD, I'm sorry but we haven't seen AMD pull anything that was THAT big a game changer since Athlon64 and since they fired all those guys for computer automated chip layouts I seriously doubt they can pull it off. finally since they kept MSFT out of the loop for so long good luck getting all those businesses who will be staying with win 7 to buy AMD when its crippled by the Win 7 scheduler.
Final verdict? Faildozer is AMD's netburst and without anything in the pipe besides it (they killed Thuban production, killed the next rev of Bobcat, all they have left is Liano and Faildozer) means for the next couple of years AMD is gonna be hurting BAD. Hell Thuban wins in most benches and was 40% cheaper to make than faildozer quad which Windows treats as a dual core with HT! As much as I love AMD when I can't get anymore Thubans and Athlons and Phenom IIs I'll have no choice but go Intel, faildozer is too hot, sucks too much power, and gives too little in return, just like netburst.
