Will Bulldozer perform well? Yes. Will Bulldozer be released before 2012 no.
Actually, I have been a strong proponent that benchmarks don't matter. Benchmarks make people feel good about products, but benchmarks don't reflect reality in most cases. With ~5% actually buying top bin processors, comparing benchmarks for processors is often a case of "mine is better" instead of focusing on what customers actually buy.
"Case and effect are interesting things. I wouldn't think the correlation between product speed and profits are at all related. And I am in marketing." Before you said this, I would never have believed you believed that.
