E8400 vs E8500 vs E8600

post #1 of 15
Thread Starter 
Not counting price, what is the main difference between these CPUs?

I have heard alot about the E8400, but yet the 8500 and 8600 are better versions. Which of these is the best overclocker, and which one would be the best out of the three? Thanks alot.

Higher multipliers.
Basically they're all topping out around the same speed when OCing.

I would get the E8400 or the E8500 since I was told at one point that they all top out around the same speed.

Maybe someone can correct me if I'm wrong, but I'm pretty sure the only difference is the multiplier.

The multi, obviously.

Also stepping. the E8600 is E0. The E8500 and E8400 were C1 but recently have been re-released as E0 steppings.


The benefit of a higher multi is lower required FSB with the motherboard and RAM.

?

I don't think so.

I've owned all 3 chips and E0 versions of the E8500 and E8600.

I have yet to see an E8400 or E8500 do 4.5ghz on air like the E8600 does (and at reasonable voltages)

I suspect that intel does some behind the scenes binning.

They are indeed binned since they started the E0 stepping for all 3 chips. I would provide proof, but can't remember exactly where it was that the information was at.

I'm at 4.176ghz and 1.208V, for example... That's less than my VID.

I can probably get ~4.4ghz at 1.3V. Above poster is at 4.0ghz.

I had the 8400 (one of the first, C1 i beleive), and now the 8500 E1. There is a massive difference between them. The 8500 overclocks with great (4.2) ease and low voltage, while the 8400 struggled to hit 3.8Ghz at the max allowed voltage!
I don't know if the price difference between the 8500 and the 8600 justifies it...
