Different Penryn processors??

Besides the obvious mhz difference there's also the cache. 2.4GHz cpu has 3Mb L2. The 2.5GHz, 2.6GHz models have 6Mb cache L2.
Let's put it this way:
A 2.6GHz cpu is faster than a 2.5GHz cpu which is faster than 2.4GHz cpu.
There more GHz you have, more speed you get. Like mph.
The cpu cache is like a much much faster RAM (system memory), it's also closer to the cpu and more expensive therefore you get less cache.
This means the more cache you have the better.
* This was a rough explanation, but I think you understand this way. *
That means increase in speed is much more noticeable when you choose 2.5GHz over 2.4GHz THAN when you choose 2.6GHz over 2.5GHz.
between 2.4 and 2.5 there's 3MB on-chip memory difference BUT
between 2.5 and 2.6 there's NO on-chip memory difference.
L2 cache is a type of memory that's on the processor itself that makes the processing of the processes faster for the processor
. so the bigger is always the better when it comes to L2 cache. wikipedia always helps if you're into more details
Have a question about the L2 Cache
Why the new Macbook has 1mb lower L2 cache than the previous Santa Rosa ?
is it no matter of lower L2 cache, the new Macbook still achieves higher speed in overall performance in all aspects?

Intel decided to cut 1 MB of it. Apple has nothing to do with it. I don't know any benchmarks about the new processors. Can't help with that. But common sense tells me overall performance was not hurt.
