The whole design of the processor is completely different. An E6300 will outrun a Pentium D at the same speeds, and even at much higher speeds.

prefetching of instructions, length of pipelines, IPCs, efficiency. All the good stuff that the C2Ds excel in over Net Burst.

Do the Core2Duo also use less energy and not get as hot?
Thank you all for taking the time out to answer my questions!

ace, you can't really say that. Your Pentium 4 might have a faster clock speed, but i doubt you can play games and run a virus scan at the same time

you're comparing apples to oranges, since they are Macs, they run on a completely different operating system. For productivity tests, you need the same foundation to compare.
