    How much is the performance difference between the P8600 (2.40GHz 1066MHz 3MBL2) processor and the T9400 (2.53GHz 1066MHz 6MBL2) processor?

    In terms of games, video editing, applications, etc, will I notice that much of difference for the .13Ghz and extra 3MBl2?

    i dont know if the 9400 is 25W. Personally I could sacrifice cache and frequency for the processor. After all you will be using your processor mostly on energy mode anyways.

    How much of an improvement is a 6MB cache over a 3MB cache? I figure for everyday office use, it won't be noticeable. For applications that max out the CPU, how much faster would they run with a 6MB vs 3MB cache?

    I do a bit of video editing and some number crunching simulation, both of which use my CPU at 100%. Battery life is not important, just pure speed. I'm trying to see if moving up to the 6MB L2 cache T9*** series CPUs are worth the money.

    Won't help much. It depends alot upon the app's coding. AFAIK, Photoshop and WinRAR do make good use of the CPU cache. If the price difference is under $100, go for the T9400.
    You can downclock and undervolt the CPU when on battery, and run the CPU at max performance when plugged in.

    the difference using the mentioned apps is in seconds, really nothing one would notice.

    The only time the small differences in CPUs matters is when you're running real-time apps, meaning GAMES.

    Other than that, who cares?

    Someone in that thread linked to an outstanding article that answered my question. It looks like you'll see a 10-15% increase in performance between the T9400 and P8400 in real world applications. But for me, since the CPU is only rarely ever the bottleneck, I'd rather spend the CPU upgrade money toward RAM or a faster hard drive.

    Thanks for all the helpful responses!
