Another Processor Question

Alright so this time its the intel core 2 duo, is the 2.14 faster than the 2.4? im pretty sure it is. Can someone help me out again? thanks

As you have already read, comparing the performance of two different processors is not so simple as just comparing processor clock speed numbers.
If the processors are the same generation, both using the same chipset, same amount of installed RAM memory, both running the same version of OS X, etc, etc - THEN you should expect that the larger number (2.4 GHz) will be faster than the smaller number (2.14).
To over-simplify... - higher processor clock speed (larger number) will be faster.

Like DeltaMac said, you can't compare two processor speeds alone -- there is much, much, much more to the "which is faster?" equation than just clock speed.

In your example, taking clock speed alone, the 2.4 is "faster" than the 2.14. That's to say that the 2.4's clock oscillates at a higher rate than the 2.14. You didn't specify which Core 2 Duo processors those were, so beyond that, it's impossible to say that the 2.4 model is faster/slower than the 2.14.

You need to take into account bus speed (how quick is the path between the processor and RAM?), size of cache (1MB? 2MB? 6MB? 12MB?), type of cache (L1? L2? L3? on-chip? off-chip?) as well as the other components in the computer that the processor is paired with (a 1.8GHz Celeron with an $800 video card will whoop the pants off of a 3.0GHz Core 2 Duo with a $30 graphics card in terms of "graphics" performance).

Your method is "flawed" in the sense that you can't just simply look at the clock speed of a processor and say, "this one is faster than that one." A good rule of thumb is to look at the prices of the processors you're comparing -- typically (but not always), the more expensive one will be "faster" overall (even if it has a lower clock speed!).
