You mean once? When we went from 32nm to 22nm? (and even then the only thing that suffered was air/water OC, everything else was up)

Not saying that broadwell will OC any better just pointing out that one die shrink is hardly enough for a trend.

Afaik the scaling has lowered on earlier processes too. You have to scale the inreases to the original clocks. Also that "only thing" happens to be propably 99% of the users. I'm not saying they are bad chips, I just wouldn't be too excited about the performance increases of Broadwell. Intel seems to be going towards the lower power consumption direction.

I'm not saying they are bad chips, I just wouldn't be too excited about the performance increases of Broadwell. Intel seems to be going towards the lower power consumption direction.

The extra potential of the chips (percentage over stock speeds) hasn't really gone down overall. It has actually stayed at relatively the same levels with SB providing a small higher than normal moment.

Yes the potential might be down from something like a 2.66ghz i7 920 D0 but this is because the 920 was pretty much the bottom bin nehalem quad.

Let's compare the highest clocked intel chips of every recent series:

process - CPU - stock speed - average max OC - OC potential in percentages

45nm - i7 965 C0 - 3.2GHz - 3.8GHz - 19%
45nm - i7 975 D0 - 3.3GHz - 4.2GHz - 27%
32nm - i7 990X - 3.46GHz - 4.4GHz - 27%
32nm - i7 2700K - 3.5GHz - 5.0GHz - 43%
32nm - i7 3970X - 3.5GHz - 5.0GHz - 43%
22nm - i7 3770K - 3.5GHz - 4.8GHz - 37%
22nm - i7 4770K - 3.5GHz - 4.7GHz - 34%
22nm - i7 4960X - 3.6GHz - 4.7GHz - 30%

Core 2 had a crapton of extreme models which I can't be bothered to list but it should also fit pretty nicely in that trend. SB was exceptional for air/water users. Otherwise different intel process nodes have always had their own characteristics when it comes to OCing. And I haven't seen any proof of a general downwards trend.

so die size at the moment will not reflect on heat dissipation ?

and why was solder not used apart from costs?

Heard some arguments over this before but forgot biggrin.gif

Anything with a TDP of 95W or over uses solder, anything under that uses thermal paste.

That's just the way intel does things...

Nice list al and i agree. For some reason i believe 14nm will overclock a lot better then 22nm

So, no.

Meh. With Haswell-E coming in around the same time, I have no interest in Broadwell. Gimme dat 8-core!!
