Early Ivy Bridge Sample Tested

[SubZero.it]

No difference even in power consumption
Considering also that it runs incredibly hotter

[eXa]

What?
111w ws 137w is quite a difference.

[STaRGaZeR]

And that's with the rest of the system included.

[paulbagz]

And that's with the rest of the system included.

Yeah not including all the extra fans and pumps you will need to keep this bad boy happy

I don't consider it as much of a plus seeing how hot the new chips are.

Does Ivy overclock BCLK better than Sandy? Or are the limitations the same?

under cold, much better; think 6.1-6.5 under LN2

[aussie-revhead]

So probably only the standard 105-106MHz on "normal" cooling?

[ziddey]

I thought I read half a year ago that IB was going to "support" 133bclk? I guess that was just a rumor.

[M.Beier]

About the electicity calculation...
Price is more like 80cents/kWh here.

I never read that, please list source if you find it again.

I remember reading that too, i thought it was on here somewhere.

[hersounds]

series 6 & series 7 are 65 nm ( chipset ) so how much can be better the bclk oc?..a little more

Intel talked about Ivy-OC on their IDF 2012 in Beijing. No need to speculate...

It's German, but click through the pictures to get the info

Wow is Intel even releasing an Overclocking utility so you can overclock from Windows and make different profiles and integrated their stress test into it as well? Interface looks nice and tidy it appears from that screenshot. That's quite a big thumbs up from me.

[aussie-revhead]

It will have to have a temp warning and override system for this cpu equivalent of first gen fermi .....

[bamtan2]

stay on topic geniuses

so we're on track for 105mhz bclk:


what does turbo ratio override partial+4 mean? does this mean locked ivy bridge chips can overclock beyond even their max turbo? I thought locked sandy bridge were limited to their max turbo.

[flesheatinvirus]

Good question, I am curious as well.

[JaD]

Precisely that. I'm always surprised by how little known this fact is, but unlocked sandy bridge CPUs can already be overclocked by up to +4x, which is applied on both min and max turbo states. So will Ivy Bridge too.

P/Z chipsets only ofc, this is precisely the reason why H chipsets were locked down: a sub-$150 dual or sub-$200 quad 3.7GHz CPU + $50 H61 mobo would have been too awesome.

[Andrew LB]

If you had done an ounce of research you'd know you were talking absolute rubbish, but it's clear that if you had it wouldn't fit in with your agenda.

Absolute rubbish? Really?

Aside from the fact that I took him at his word regarding the 80 cents/kWh and it turned out to be incorrect, everything else I stated is completely factual. FYI, that link u posted says Denmark pays 0.31 euro/kWh which is about $0.40 usd. Here in the United States the National average is $0.11 usd/kWh. 4x our prices.
Then there is Petrol, which if priced in gallons/dollars would be roughly $8.00usd/gallon. Double our prices.

The costs don't stop there. Everything you purchase includes in its price a percentage that is directly related to cap-and-trade policy and the additional cost in manufacturing, shipping, and even farming. None of that comes close to the largest cost of cap-and-trade which effects every man, woman, and child. The negative effect such a system has on a nations economic growth.

[JaD]

Yeah, right. Now if you ever get out of your stars and stripes bubble you should understand how astoundingly high quality of life is in Scandinavian countries.
Those prices are inflated to push the population towards public transport instead of owning cars (which are also taxed to around twice their commercial value) and live their life in a more environmentally concious way. A closed superficial mind would think people's money's being stolen, but the revenue from those taxes is used to support the AMAZING services the government provides, and if you ever visited Denmark you would have realised how out-if-this-world that place is. EVERYTHING. IS. PERFECT. There is not one thing that does not work. Not a single soul is left struggling to survive in case of need, there are jobs for everyone-they find it for you-and your work is very well paid: average minimum wage is $23.000 dollars/year(15 in the US), and while the GDP might be lower, we all know how the infamous 1% skews that value for a big part in the US. So yeah, maybe they're not ruling the world's economy, but, to the average person, life there is so much easier to live that nobody cares.

Your argument might work for countries like Italy, Spain, France or Greece. But quality of life in Scandinavian countries is so high that comparing it to the US is like comparing yourself to Mexico.

I was wondering, is Ivy Bridge really hotter or does it just have a more accurate temperature sensor?

[JaD]

Or more inaccurate? We can only speculate about that.

[RPGWiZaRD]

Yea I'm really looking forward to some heatsink sensor placed tests where they'd just swap CPUs between Ivy and Sandy and then check temperatures of the sensor placed on the heatsink. Something smells a bit fishy of how the software temperature skyrockets when approaching 4.7GHz clocks, that it would become like 80% hotter ~ twice as hot as Sandy is a bit hard to believe.

At least I'm highly skeptical but I'm like that by nature and never usually take software readings for granted, I usually trust my senses & logical thinking more and the arguments that speaks for software to be inaccurate in this case would be how we're talking about 40C differences here and how Intel that is such a large & advanced company usually doesn't fail that bad in terms of voltage leakage, 10~15C or so maybe (still have to take into account the transition from 45nm to 22nm and the common trend with dieshrinked chips) with the introduction of trigate transistors if these would be behind the cause of higher leakage but like 35-40C? I'm sure Intel's advanced tests/equipment had easily picked that up and the engineers wouldn't have accepted such kind of leakage in first place even if we're talking of more higher clocks here. Therefore I'm personally a bit skeptical about this temp still.

Personally I'd also value if some1 could be doing some "good-cause" experiments and just keep going with aircooling until voltage/clock frequency hits a wall and ignore CPU temp even if it reads like 100C haha, if it continues to clock somewhat despite readings are at like 100C you should also get a bit skeptical.

[Cold Fussion]

Why are you assuming the cause of running hotter is higher leakage?

[RPGWiZaRD]

Why are you assuming the cause of running hotter is higher leakage?

Because

- Stock temps looks a lot better and the temp seems to rise at the higher clocks a lot faster than the increase in voltage required.
- Subzero-OC friendly
- Comparing 45nm to 22nm with barely any performance increases I doubt Intel decision makers would just pat the back of the engineers and say good job making 10% faster chip with 50%+ higher temp.
- 40C temp differences only due to different internal designs when going from a 45nm to 22nm process seems to go out of the border what's realistic "goals" using common sense. Maybe if we're talking about entirely different kind of company/resources/devices whatever but not for such a large scale important player in the IT business.

Leakage makes more sense than Intel accepting a design which would be the cause of such a large boost in temp as if it's leakage it would only be a prob at clock frequencies which are way out of their targeted clock range (no big deal if it does handle the targeted clocks good enough)
