Well, the CoreDuo is a brand new dual-core CPU with four times the level 2 cache and a higher clock rate on an efficient core (comparable ISP to AMD64). It BETTER be faster! If it can't beat a four year-old single-core processor with one fourth the level 2 cache and a lower clock rate, it'd be mighty sad indeed. :lol:
You'd have to compare the CoreDuo with a 970MP based system to do a fair comparison... not that Apple is likely to release anymore 970MP systems. Suffice it to say that the new CoreDuo systems are better, but you expect newer systems to be better. It's the way the computer industry works (unlike many other industries). Always giving you more for less money.
