What's the improvement in the latest Intel Z77 CPU's?

Hi Folks,
I'm an x AMD'er and that's because it became painfully obvious that if I wanted to get to 5Ghz, I was going to have to go Intel. Yes, yes, I know some folks got their AMD's to 5GHz but 5 GHz in an AMD seems to be the equivalent of about 3.4GHz in an Intel. (I'm speaking real-world applications).

But honestly, I truly am not here to shoot down any CPU AMD or otherwise and frankly, I'd go to what ever processor performs the best for my budget, regardless of brand.

I honestly would like to know what the latest Intel processors offer that the previous ones like the i7 2600K don't?

I'll admit that I haven't done a 'focused' search for top performance in the newest Intel's, but I haven't seen many that have accomplished a 5GHz O/C.

Does this mean that they don't have to run 5GHz in order to give the same performance as a i7-2600K O/C'd to 5GHz?

Or does it mean that they can't get there? Or!... Does it mean that I just haven't looked at or read enough articles?!

Anyway, I just wanted to know what the advantage to the latest Intel's were over the processors like mine or even the i5' or i3's of the previous versions.
Thanks, Rich

Ivy Bridge chips (the 3xxx series) offer PCIe 3.0, an improved memory controller (to support higher mem speeds) and an improvement in IPC (about 10% or so). They also run hotter when overclocked, but the IPC improvements kind of even it out. So you can get similar performance to a 5.0 2600K with a 4.8ish 3770K.

If you want 5.0 on a 3xxx chip you are probably going to have to either get lucky with a good chip, have really good cooling, or be willing to de-lid the chip by taking the IHS off and replacing the TIM. A normal system is going to struggle to keep a stock 3xxx cool at 5.0 speeds.

Ivy Bridge is slightly faster than Sandy Bridge, takes slightly less power, and has more advanced integrated graphics Basically, Ivy Bridge is Sandy Bridge all cleaned up and "perfected" ever so slightly, Ivy bridge includes USB 3 and PCI-E 3.0 support which Sandy bridge didn't . There have also been improvements made to the memory controller.

Many people have done comparisions between the two already and found there isn't really that much difference between the two and don't recommend upgrading from one to the other, but they do suggest ivy bridge if you are skipping Sandy all together.

have a read for yourself on the link below.

Basically, you get a 3770k, delid it and throw in a custom loop or a decent AIO water cooling setup; that should have you at 5.0GHz no problem unless you have terrible luck. A 2600k 5.0GHz chip will be a littler harder to come by, but if you can find it then it wouldn't be a bad opportunity to jump on either.

Only thing is you can destroy your new chip by delidding it.

Thank You All! Ardalista, I appreciate the link, I'll check it out as soon as I get a chance. I have suspected that the 3xxx processors may not have been the biggest leap forward that some folks thought it would be by the little bit of reading I did regarding O/C posts from different websites.

I had no problem getting my i7-2600k to 5 GHZ and it runs very stable and I don't use high-end water cooling but the closed-loop, H-100 Corsair definitely plays a significant role. Still, I only run at 5GHz when I'm in a flight-sim. Otherwise, for everyday use, I run it at 4.2Ghz. It's just been doing great but I was curious about those.

I did recently read that the Z77 Chipset is about to change to a Z78, (I think they said Z78), and the people who were talking about it seemed excited and implied that the new Chipset will be a big improvement.

My mobo has the Z77 chipset but I'll probably never make use of it. Frankly, I know that there will always be a new 'bigger and faster' product on the horizon but as long as I get the results I want, I'll likely stick with what I'm running.

At least until I start seeing some 6.GHz's out there!thumb.gif
Thanks again, Rich
