This is an example of the benchmark I would like ran in Truecrypt:

IMO you'll find out that voltage required for under 4.5 Ghz stability is less than SB (think 1.1V vs. 1.2V+ that most SB require), and that power consumption is accordingly much lower. That's the strength of IB, moderately high clocks with a significant reduction in power.
It's not all about maximum frequency. A 4.4 Ghz IB running at 1.1V will outpace a 4.5Ghz SB running at 1.25V while using 30-40% less power (augmented from 20% stock vs. stock power savings).
LagunaX, try a more reasonable overclock under 4.5 Ghz, and find the lowest stable voltage. I think that will make IB look much more interesting.
It's hard to believe one 3570k would run at 85 C and another would max out at high 50's...................... If you know what I'm sayin
So you're saying a chip with an 18 watt delta at stock is going to net you 40% less power overclocked? ... even though the results show you still need about the same amount of voltage to get the same clocks as SB? That's some seriously wishful thinking.
No, the premise is that it requires less voltage. i.e. 4.4 Ghz with 1.1V vs. 1.2V for SB.
Lesson learnt: don't bother with Intel ticks.
Thanks so much for doing that. Now can anyone tell me if intel turbo overclocking is still on in these situation? Is the chip going to overclock further by itself?4.0ghz stock volts, nice load temps 50's:

4.2ghz stock volts, nice load temps 50's:

4.5ghz 1.24v, ok load temps low 70's:

I would not be so sure about that. The difference is smaller, but definitely not negligible (this is at 3x 1080p resolutions)
Edit: I was one of the first people on OCN to prime95 blend my first i5-2500k @5GHz, and it took 1.52v to do it. As time went by people started getting better chips, really good ones could do it slightly below 1.4v, but most were over 1.4v for 5GHz in prime95 anyways. Point is, the sample base needs to be much higher than what it currently is before we rule out IB. Plus some people just have more balls than others and will run higher voltage with better cooling.
for the entusiast market, Ivy seems to be a very big fail
I say keep the motherboard and buy another, that way you'll have 3 boards waiting to confirm 1.5v kills Ivy bridge chips.
That, is not certain.And there will be a large socket IVB in another 8-12 months, so the performance crowd is not being abandoned or anything.
That, is not certain.
One will die one day, that is the only thing certain.It, is.
Google, you must learn to.
Repeat, one must not same old BS and lies.
Not a large enough sample base yet, there are a lot of SB chips that people tap out at 4.4GHz 1.3v.
I wonder how Ivys would perform if they were made at plain 22nm ie without 3D xtors.
Would they be better or worse in terms of overclocking?
