    Given the same cpu, how much difference does the extra cache make real world?
    Also how can AMD cpus have a higher model number and a lower clock speed than a chip with a lower model number?
    i.e 3700+ = 2.2 ghx, and 3400+ = 2.4 ghz?

    The AMD CPU model number designates what it's performance is equivalant to in an Intel CPU. So an AMD 3700+ performs on par with an Intel 3.7 Ghz. Most of this disparity is due to AMDs HT bus which is nearly 2 1/2 times faster than Intels bus. Since your CPU spends most of it's time in a wait state (waiting for data) the increased speed of the HT bus has a big affect performance.

    In your comparison the 3700 is a socket 939 and the 3400 is a socket 754. The 939 utilizes a 1000 Mhz FSB where the 754 utilizes an 800 Mhz FSB. That's where the disparity lies.

    Cache memory can make a difference to point. 256 KB to 512 KB can make a huge difference 512 KB to 1 MB not so much. Alot depends on what the application is also, DAW, Gaming, word processor. It's pretty much always diminishing returns the higher you go.

    Also keep in mind that the AMD chips are designed to be overclocked.

    For instance, my 1700+ says it's clock speed is 1.4GHz but it runs best when clocked up to 1.7GHz.

    Like D said, the 3700 will perform best when clocked in Bios at 3.7GHz rather than the advertised spec. of 3.4 (or whatever it is).
