This is somewhat like a 2500k vs 3570k question... But, it has a somewhat definite answer, which is why i wanted ask you guys here, at tom's hardware.

Heres the question once again:
At what clock speed is the 2500k equal to the performance of the 3570k?

Maybe you could tell me what you think and give me voltage values and clock speeds at which these two cpus intersect/ collide or break even or are perfectly matched.. Whatever you wanna call it :lol: 

Awaiting enlightenment.. :D

It's a 5-10% difference in most cases (which I'm guessing you already know), but I don't feel like doing the math right now. :lol: 

Just add ~300Mhz to a 2500K to equal a 3570K basically.

I'm too tired right now to break down all the voltage differences at different clock speeds, etc. :pt1cable:  :lol:

Well, IB is about 5% more efficient per clock so SB would need to be clocked 5% higher to match it. f.ex. 3.4 GHz IB ~ 3.57 GHz SB

3570k 4.2ghz act as the speed of 2500k 4.5ghz, ivy-bridge cpu's have more efficieny.

:lol:  I know what you mean..
Thts exactly why i started this thread. :D 

Anyway, i was really hoping for some Temp-Voltage-clockspeed graphs. Wanted to know how the 3570K compares in terms of its marginally decreasing returns and where its at its best against the 2500K without sacrificing on the temps.

So, Any case study out there?
Anyone that can enlighten me?

Still Awaiting Enlightenment ;)

It depends on too many variables to have a definite study, especially withot testing thousands of samples.
