Ressources is as you say a combination of budget and scope. And we know nothing about the scope. Yes it looks starved looking from the outside, especially because of the software burden as you say, but the devil is in deep complexity, and there is nothing we can know about that. Look how fast the K12 is comming. It shows the scope compared to BD is quite smaller - perhaps a magnitude.
Given that resources are a lot less than before and the time frame is given (2016, 4 years in R&D), we can only deduce that scope will be much smaller than Bulldozer was. I'd say that it will be closer to the cat core than from Bulldozer in terms of raw performance and other parameters. It shouldn't be remotely compared to Haswell.
Nobody really knew how bad BD arch was
Sorry, but AMD management knew, otherwise they wouldn't have taken the then-dramatic steps of axing the FX/Opteron line, bringing in a new chief architect and design a new uarch from the scratch. If they didn't know how bad Bulldozer was, I don't think the old management team would have been fired at all. I think that at least in december 2010, *before* Dirk Meyer was fired, AMD had a clear idea of the train wreck in their hands. They just couldn't be open about it because otherwise their marketing efforts would unnecessarily suffer from the bad press it would generate and they didn't know what to do about it. Only in 2013 with sales foundering and the ARM strategy in place is that they could be candid about how bad it was (the unmitigated failure comment from Andrew Feldman).
