You guys apparently don't realize that:
performance != performance/clock (IPC)
IPC != single-threaded IPC
and that the Alsup statement was about the *Integer* pipeline.
It doesn't matter how big the font is that says "Single-thread performance is higher." or "Bulldozer IPC will be higher." Neither of those address the Alsup claim which was that:
Single-threaded integer performance PER CLOCK (i.e. IPC) will be ~5% lower.
I would not have thought that the distinction would require a great deal of analytical reasoning ability to comprehend, but the numerous replies (with one exception that I've seen) indicate that I am either incorrect in my assessment or that educational systems are failing.
And really, all the personal stuff because someone posts something you disagree with? Really?
