i7 4770k vs i7 4770

Hello everyone,
In a week I will build a gaming rig. Cpu cooler will be cm 212 evo. So my question is: How much Ghz will I get with 4770k ? Will it be even worth the unclocked one ? I mean 3,9ghz with turbo non k i7. Assuming I would not get over 4,2 ghz on k version will it be difference ? 300 mhz ?

  1. If you'll not overclock then Yes
  2. Hey

    The turbo 3.9 GHz will work on one core, if all 4 turbo boosted that will be 3.6/3,6 GHz not 3.9.
    With a 212 you can go 4.4 GHz but that a lot, a 4.2 would be safe and the performance great

    4.2 GHz i7 4770K will have about 30% more performance than 4770
  3. How high you can go by OC on certain processor even with unlocked multiplier is different from system to system, to be exact from processor to processor even if the processor are suppose to be the same.
    It is a game of luck, if you are lucky, you can go really high.
    Other factors like coolling and stuffs are only the infrastructure of the OC but the real limit is the processor itself.

    Open multiplier is simply making your OC life easier and nothing more.

    If you do not plan to OC, there is no difference between i7 4770 and i7 4770k.
    You might as well take E3-1230V3 if you do not OC and do not plan to use the iGPU.

    The stock speed is 3.4 vs 3.5. You would need the i7-4771 to match the 4770K stock 3.5GHz speed. They all boost to 3.9GHz, however, that is only on a single core. Even if you got the 4770K and OCed to 3.9GHz, it would be on all 4 cores and would perform much better than the non-K version. Chances are you should be able to get to 4.0-4.2GHz without any issues. The Hasewell chips seems to be the luck of the draw with OCing. I could only get mine to 4.3GHz and was impossible to get stable at 4.4 no matter what I did. It is definitely worth it.

    PS. The 4770K is the same price as the 4770 on right now. Just thought I'd throw that out there. So this would make the choice a no brainer... AND because Mike Rowe said so.
  5. I second the 1230v3 option if not wanting to overclock. Allows for a cheaper motherboard too, unless you are wanting to do SLI or CF.

  6. From the answers above, I believe we need your feedback now.
    What are your expectations? OC or no OC? Do you want to use the iGPU or not?
    Choosing i7 4770k without any OC plan and/or iGPU usage in mind..well..i7 4770k is not effective.
  7. No overclock and want IGP, the 1245 v3 is still usually a less expensive option than a 4770, just as an FYI.
  8. Ofcourse If I get the K chip I'll oc it. I was wondering how much Ghz could I get with evo 212 and MSI Z87-G43. My main purpose is if Z87 and 4770k and evo 212 is worth over H87 and 4770 and evo 212. And how much I get oc it. I was told that haswells are bad for overclock as well as ivy bridge is.
  9. I am happy with my OC on my 4770K. I wish it could be higher, given it stays pretty cool with my Thermalright cooler. The Evo would keep it decently cool. I would think you could get 4.2 out of it without a sweat as long as the CPU allows it. If you go with an H87 and 4770 I would think you could be allocating funds to something else, like a better video card or something.
