On Topic:
Well if those numbers are true it's again rather sad but looks like BD had a flaw in multi-threading since those numbers have increased. Sadly what AMD needs is better single-threaded performance.
Multithreaded is due to higher base clocks.
He is especially testing fp performance which we know didn't change alot and 5% is better than nothing.
superPi? cine 10 and 11.5. (basically the same thing) and CPUmark99.
Luckily in most of those applications single thread performance is of little importance as they scale pretty well with threads.
Piledriver architecture has the best increases in integer performance..
Do we expect miracles? ofcourse not... but we already knew what we could expect the moment Bulldozer left the building... and untill they can be competitive with the process... bulldozer will stay only competitive in very few areas.
