Okay, heres a pretty dumb question, here it goes.
 
So lets say I have a Q9300 and a Q9450.
 
The Q9300 is a 2.5GHz stock and the Q9450 is a 2.66GHz stock.
 
My question is will the Q9450 over clock better than Q9300 even though they are the same architecture or is the Q9450 just a higher clocked Q9300.
 
Thanks in advance.

The Q9450 has a multiplier of 8 while the Q9300 has multiplier of 7.5. Although the potential for OCing might be the same, due to the lower multiplier of the Q9300, the motherboard will be the limiting factor.
 
Using an example, say the max OC for a motherboard is 500MHz fsb. Thus the Q9450 will be able to do 8x500 = 4.0GHz and the Q9300 will be able to do 7.5x500 = 3.75GHz. Although the potential for these two cpus is much greater, like 4.5GHz, they are ultimately limited by the motherboard.
 
So, to answer your question, the Q9450 will be better in terms of OCing strictly due to it's higher multiplier.

thanks, thats all I wanted to know

dang double post

9450 also have 12mb of l2 cache, compared to 9330's 6mb, so at the same clock, 9450 will be faster.
