I7-3770k vs i7-2700k

Ok so I have an option of buying either one of these brand new, the 3770k is 220 GBP and the 2700k is 185 GBP.

Would the Ivy Bridge actually be worth the extra 35 quid?

Thanks.

  1. Once both are overclocked the difference is so tiny it's not worth worrying about.

    If you are running both stock then it's worth 35.

    The ivy bridge part also gives you a better iGPU and PCI 3.0

    What doesn't your i5 do at the moment?
  2. Go with i7 2600k as spending more on 3770k is not worthwile.but why you want i7?
  3. I want an i7 because I have the non-K edition of the i5-2500 and I can't overclock past 3.8ghz. I found somewhere where I can get them cheap so I figured I might as well.
  4. Also I can sell my i5 to reduce the cost ;)
  5. Go for the cheaper option
  6. Are you finding that a sandy Bridge i5 running at 3.8Ghz is not enough performance?

    I can't imagine many games that would need more CPU power than that.
  7. You can get a i5 3570k for even less than both of those. You can't need more performance than that?
  8. I'm just thinking in terms of future proofing because games will soon start to use more than 4 threads now that the next-gen consoles are coming out and have x86 architectures with 8 threads....
  9. IF you ar not thinking of a haswell upgrade or next then get the best you can afford. I think Crysis 3 actually did benefit from hyperthreading this time round.

    The Ivy i7 gives you best chance of lasting future GPU upgrades because of PCIE 3.0 but if you want more CPU power in the future then the sandy parts will be fine.
  10. While nothjing is future proof, the IB processor has greater adaptability because of PCI 3.0 and will overpower the SB CPU when they develop apps that utilize PCI 3.0. I recommend the 3770K because of this.
  11. Thanks guys I think I will just wait for next gen processors ie haswell and steamroller.
  12. Ivy bridge sucks tbh, good for HTPC's that's all. The 2700k is a much better chip anyway with Haswell around the corner you would be wise to wait a while longer!

    Why do you say that?
  14. Performance wise ivy>sandy
    A 3770k@4.5GHz=2700k@4.7Ghz
    But the 2700k will overclock little better and its 95w TDP 32nm chip where as 3770k gets hot quickly and 77w 22nm Chip. So end of the day not much difference in my opinion its realy on users choice/need.
    If you spending the extra £35 than you should have a Z77 Motherboard I assume.
    If your not going for Gen3 PCIE3.0 mobo z68 mobo than 2700k is right choice as only 3770k/3570k ivybridge has inbuilt support for PCIE3.0
    Having said that PCIE 3.0 as of now doesnt make any noticable difference in real life situation but will be in near future)
    If your looking to get the Gen3 PCIE3.0 Z77 Motherboard than it needs a 3770k
    Thanks
  15. Intel has improved the thermal dynamics of the IB line since the early release (I believe that they now use a better paste, but it is still not solder). While the SB processor can be better OCd, the IB is still competative at a reduced speed because of its 15% performance advantage over the SB. Simply put: if a SB 2500K is OCd to 4.6 GHz, it can do the same workload as the IB 3570K OCd to 4.0 GHz.

    Redeemer may be a speed demon, but IB still rips the doors off the SB at the same clock speed.

    & imomun a 4.5 GHz IB = a 5.175 GHz SB (not 4.7).

    Is it ? Damn I must be equivalent to SB 4.5 or so ?

    What can I say Im delighted. LOL

    Thanks
  17. Actually there was a test done that showed that at the same clock speed, the Ivy Bridge CPU's are on avarage 4% faster than Sandy Bridge.
    Sandy Bridge CPU's however overclock a bit higher than IB on avarage, so essentially you get better performance for less.

    And lastly, No PCI-E 3 will never bring any extra performance, unless you're running a high-end card on a 4x slot.

    There is just no point in spending that much more, only to get a 5% performance improvement at stock clocks.

    With due respect a HD7970 or GTX680 as seen on your link is not topping the bandwith hence you dont see a difference think of a future card with 3 times faster bandwith which will eventualy comeout, will it deliver the same as PCIE 3.0 x16 Slot in a PCIE2.0 x16 or x8? There will be some or less bottoleneck speacialy on High resolution Extreme texture AntiAliasing ETC.

    No body wants a K CPU for stock so it doesnt matter in reality.

    But I see your point and to some extant I agree the PCIE 3.0 has no real use at present and by the time it gets useful it might be time to change entire platform. Future is realy uncertain speacialy with technology. Its running faster than my Fiat LOL

    Thanks
