Haswell vs. Ivy Bridge Overclocking

Discussion in 'CPUs and Overclocking' started by cbn, Jan 31, 2013.

?

How well do you think Haswell desktop will overclock compared to Ivy Bridge desktop?

  1. Greater than 500 Mhz faster

  2. 300 to 500 Mhz faster

  3. 100 to 300 Mhz faster

  4. Haswell will overclock roughly the same as Ivy Bridge

  5. 100 to 300 Mhz slower

  6. 300 to 500 Mhz slower

  7. Greater than 500 Mhz slower

    How well do you think Haswell desktop will overclock compared to Ivy Bridge desktop? (Assume the average max OC using large tower air coolers for both processors)

    Umm, no one knows (that isn't an Intel employee)...... What is this thread for?

    It is just a speculation thread.

    Some things to consider:

    1. Material used under Haswell's heatspreader? Will it be TIM (as in Ivy Bridge) or solder?

    2. Haswell specific changes to the 22nm process node?

    Due to laziness in figuring out how to solder it... "our previous method won't work... what should we do?"... "ahh screw it, just toss goo on it".

    couple factors going on here

    1. Intel has more experience with 22nm
    2. IIRC, it has been mentioned that Intel is going back to solder
    3. It has been made known that Haswell will have overclocking friendly features more than unlocked multiplier made available

    Really, the only thing that could potentially go against Haswell is that its possible the design isn't as friendly to higher clockrates, however that would then most likely mean its IPC is that much more beastly and people are going to be happy regardless - for instance, even with all the OC advantages, if Haswell can only muster ~4.6GHz but yet is 10-15% faster that's basically like having a 5-5.2GHz Ivy, not bad.

    That being said, I don't necessarily think IPC improvements will be quit that good, however I am leaning towards 4.8+GHz being more of a norm.

    I think, Haswell will be OC similar as Sandy, so between 4700-5100 MHz stable

    I'm hoping for 5 GHZ average newb overclocking as opposed to 4,6-4,7 ranges.


    Without too much voltage - but i'm not thinking it's realistic :C

    I hope it's a terrible over-clocker so that I'm not tempted to upgrade. :p

    I'm guessing 5GHz will be the norm with Haswell but then again, that's the same prediction I made with IB and it didn't turn out that way. Assuming the 22nm process has matured since IB, 5Ghz should be possible. With my lemon Core i5 3570K, I could go 5GHz with no temp constraints but it will still be unstable at suicide run voltages.

    if I can get 5.29Ghz stable, then i'll be happy. lol :D

    Given that the development resources for Haswell were devoted to prioritizing performance scaling at the low-end of power and clockspeed, I very much doubt we are going to see much added clockspeed headroom over that of what we already see with IB.

    For starters, where is the money in it for Intel? The portion of the market that comprises enthusiast OC'ers who are going to have make-or-break purchasing decisions on the basis of whether or not a 3.5GHz Haswell can overclock beyond 5GHz on air has got to be silly, truly silly, small.

    So how can we, the six of us who care, really expect Intel to have devoted resources towards engineering Haswell to have ">5GHz OC'ing headroom, ya know, for those six dudes who won't buy Haswell if it doesn't do that"?

    Meanwhile they are looking at a market with the potential revenue of billions of dollars if they can get the performance/watt tuned to fit within the right max wattage...that opportunity justifies expending R&D dollars and it is not an opportunity that requires tuning neither the microarchitecture nor the process technology to function in the >5GHz region of the shmoo plot.

    ...because of ePeen yo.

    Gotz to hav dat biggest ePeen, yo.

    AMDz ain't gotz nuttin on uz Intelz - guyz man com on!.



    Atleast - that's how i imagine\hope the marketing head pitching it to Otellini :p

    Ironically I imagine that is rather precisely how the internal marketing pitch for bulldozer went with Dirk.

    A truly epic tale of clockspeed and e-peen fanboys. A proud moment for Dirk no doubt.

    I'm not quite the advocate of reaching such speeds. I'd be happy enough if Intel improves their Turbo Boost on desktop chips to reach near 1GHz(~4.4-4.5GHz). Current mobile chips do come with 1GHz Turbo Boost. Unless, Intel knows that Turbo Boost beyond 4GHz creates new problems or the likelihood of finding a golden chip that does that is difficult.

    That would be nice :thumbsup: A 4.5Ghz turbo-boost model would be great.

    My hope for IVB was 5.3ghz Couldn't get stable at 5.3ghz but its good at 5.2 ghz . For Haswell If I can get 5.5 ghz stable I will be more than happy.

    I am not so sure that a 1Ghz turboboost would be great. It leaves the possibility for too much performance delta between 2 different environment settings.

    :whiste: At this point I dont have a clue but I am looking forward to finding out.

    BTW there is a new promo that will be lunching in the next couple days www.intelgamingpromo.com

    Hey, you live in Denmark, I live in Scotland- so at least we'd be on the right side of that delta! :whiste:

    It won't be a very effective promotion if it gets eaten.
