    I have an 27' iMac 3.20 Ghz i3. I would like to know the difference between that chip and the 3.33 Ghz C2D. faster? slower? better ? I feel that I made a mistake trading in my 21.5" 3.33 Ghz C2D for the 27" i3 3.20. explain why is it better or not, in detail. If someone would, I would so greatly appreciate the education and ease of mind.

    i3 has a 32nm structure vs the 45nm C2D configuration (i think the numbers are correct)

    so more transistors packed into the same area, therefore more data can be processed at once

    also I know the i3 uses less power consumption

    The Core i3 is faster than that Core 2 Duo... Who traded it and why?!

    The new i3 chips are clarkdales, which are successor to desktop grade core2duo chips. They have a newer architecture (nehalem) vs older core2 architecture.

    The benefits that come with nehalem architecture are that it runs cooler (thanks to more integration and/or smaller manufacturing process.) Has hyperthreading (tricking the OS into believing the cpu has double the amount of its physical cores-- a program that uses 4 threads/cores will use 4 logical cores on a dual core, hyperthreaded i3 clarkdale)
    Turboboost is essentially the cpu overclocking itself when it needs extra power (i3s do not have this)
    General advances in performance per clock-- around 20% greater.

    Who else remembers when Turbo meant pressing the button on the front of the desktop to change the processor's clock speed?

    I remember the turbo button very well. Along with green screens and orange screens.

    I was ordering computers once and my boss told me "20 megabyte hard drives? We'll NEVER fill them up!"

    I remember when I bought my first computer in '92/93, it had 2MB of RAM. I also had WordPerfect and Lotus 123 as the first two software purchased. Haha, seemed like a lifetime away...
