    Keep your Sandy Bridge!

    E1 Ivy Bridge are significantly worse Ocers on air!

    11431989.jpg

    I have two older Engineering Samples stepping 8 (E0) and they are really good "on air" Ocers. Retail E1 stepping 9 is noticeably worse. It is worse than any Sandy Bridge. All Sandy Bridge I saw last year are better than all available E1 Retail stepping Core i7-3770K!. Ivy Bridge E1 is not good on air ocer! Do not buy them instead of your 5 GHz Sandy! Only for LN2, there make sense ... never for on air ocing! Keep your 5+GHz Sandies, no E1 Ivy is capable that clock on air.

    PS. This is first time in last ten years, i dont recommend "on air" overclockers to upgrade older Intel CPUs for new.

    ...is this serious? is really first generation trigate 3D guilty ?

    NEW DATA ADDED

    Why is Ivy Bridge HOT, power hunger and bad clocker? - immatured 22nm process ...

    Maybe you know, Ivy Bridge are around the corner. Maybe you knows too, they are worst clocker then Sandy Bridge. We know why ...

    As you know, Intel is with the 22nm production late. Production is not good, and there are big problems with the chips. The original "on paper" concept of 22nm chip with Tri-gate transistors is extremely low supply voltage. But, with current revisions Intel can not keep voltage in planned values. This is a problem. The chips have a higher voltage than planned, broadly comparable with Sandy Bridge. And that's wrong.

    Tri-gate transistor needs to switch to a lower voltage. But for a correct recognition of the I/O status needs more current than planar transistor. Three-gate area is greater than one-gate and the current is several times higher than in Sandy Bridge chips. When Intel reach a planned low voltage, everything will be fine. Lower voltage means acceptable currents, less leakage and a great consumption. Unfortunately, it does not meet the current "E1" revision.

    Current 22nm chips have high voltage, higher than they should have. The values are similar to Sandy Bridge chips. Properly should be the default voltage below 1V and it is not now. But Ivy Bridge needs a lower voltage, at the same voltage as Sandy Bridge consumption and temperature is significantly higher due to higher currents in the chip.

    Basic Ivy Bridge idle voltage is above 1V, higher than Sandy Bridge. The load voltage is lower than that of Sandy Bridge and consumption is lower, but temperatures are higher. If the Ivy Bridge voltage increases, consumption and temperatures extremely jumps up. This problem can be solved only by improving the production, so maybe its time for another revision. Indeed it may be a potential problem in laptops with the highest third-generation Core i7 models.

    In the desktop this problem occur with less overclocking than Sandy Bridge and significantly higher power consumption and temperatures. If you have a nice 5GHz + Sandy Bridge, keep it for now. Ivy Bridge ends with overclocking on the air somewhere around 4.6 to 4.7 GHz. But slightly lower overclocking then Sandies compensates higher performance per clock, so it is not a major problem.

    There is ALWAYS the chance of getting a poor clocking CPU, that doesnt mean they are all crap.

    This is inline with another report I read somewhere. I don't remember where so it may have been the same source. Either way, I want Ivy to hit so Sandy prices will drop (2500K ftw!). This Pentium 4 D I'm using is a nightmare!

    FUGGER, on air or sub zero? On air I haven't seen results close to SB. 3D performance is up nicely though, even without MVP From my experience, I'll keep SB for 24/7 though.

    I feel your pain. I have to use a P4 (HT) at work (and on rare occasion, a Core 2) and it's torture to use it after being on my home computer.

    How many of you have a sandy that can do 5ghz stable under air with less than 1.35v? I mean that is the ideal air cooled sandy, but how realistic is it? I know my 2600K maxes at 5.2ghz on air and water and its a retail.

    Your logic is flawed IMO. The Sandy at 1.5V will still run cooler than the Ivy at 1.35V and possibly out clock it as well. Don't get me wrong I'll be getting one just for s and giggles but if it can't do, and it probably won't, 5 Gees reliably and not burn a hole in my mobo i'll be getting rid of it and putting my good ol Sandy back.

    aren't 2700k "better" 2600k's, or cherry picked ones? because 3770k is to be compared to 2700k not 2600k...

    i guess we'll figure it out soon, anyway, changing the cpu in a few month won't be too much pain if ivy is really worth it, might even gain something with future stepping and/or revisions...

    What about water since thats kind of in between? (not as ridiculous as LN2 with the tri-gate obviously, but j/w)
    Why yes, yes I do use Koolance..*Flame Wall Inbound*

    This thread made me laugh.

    Especially QuadDamage's comment. Let him buy an Ivy Bridge chip and give it 1.5v for 24/7 use.

    Huh?? He said that Sandy Bridge (2600K) at 1.5v will be cooler than Ivy Bridge (3770K) at 1.35v, and he's right.

    I thought he was saying the opposite.
    I should sleep more. O.o

    Maybe Intel decided to cripple Ivy because they have so many SB they need to sell first.

    Will there be an E2 soon after E1 comes out? Maybe within 3-5 months? Hopefully.
