More Ivy Bridge benchmarks - Sandybridge comparison - 3770K vs 2600K (Performance, temps etc) "Couple Of LN2 scores are up" - Page 34

post #331 of 690
Looks like I am holding for the next CPU generation, I don't really see a point to upgrade to IVY for such low performance increases hell I could push my 2500k @ 5 Ghz which is fully capable of and get a larger benefit than getting an ivy and running it @ 4.5 Ghz :/

On one hand I am sad to see such small differences but then again I am happy with 2500k remaining so competitive.

Out of curiosity, could you do some comparisons using your 3xGPU's in graphic benches? Perhaps Heaven and Tropico benches - if you have the time.
Would be interesting to see how Ivy handles that much GPU power vs Sandy.
Thanks and cheers, -SS

That will be harder, i have the Maximus V Gene and it's a m-ATX board with only 2x PCI lanes, all other boards i have are P67, and those are limited to 3.8Ghz ATM.

I will deff be running some 3dMark 11 and Vantage with 2x 680's / 7970's with the 3770K's under LN2 once i get them.

Interesting benchmarks. 7% increase in handbrake at 3.4GHz is pretty impressive.

No problem.

Looking forward to the latter test you'll be doing with the 2x680's and 7970's. drool.gif

Wow, so IVY is 5C hotter at 1.1V, 10C hotter at 1.2v, and 15C hotter at 1.3v than Sandy. At normal ambients 1.3v is going to be in 70's, with HT off. Thanks again for testing thumb.gif

Intel's die attach is 80 W/mk solder, which they had to upgrade from ~4-6 w/mK paste in past when power density got too high for paste with die shrinks.

Although some of heat is leakage from new tech and should improve with further refinements/stepping, I am thinking intel needs to update their die attach/IHS. There are 160 W/mk die attaches available using indium-graphene instead of indium-solder and IHS copper-graphene instead of copper, which not only has higher conductance, but is apparently cheaper/cost effective.

LOL oh my god this forum is so obviously sponsored, Ok im gonna shut up rigthnow for respect to older members, any way if intel launching a bad processor as i think, people will realize it soon or later. Evidence is here.

Let me fix that for you

I opted for the Asrock fatal1ty Z77 pro 18+8 power phase and managed to get my year old 2500k over 5ghz stable for the first time.
Previous best was 4.8 @ 1.45v on P67 Now im at 5ghz 1.4v

Get the best you can afford thumb.gif

If you were following your advice, shouldn't you have bought the Gigabyte instead? o_O

After having an ASrock catch on fire at 1.3v, breathing in the toxic green cloud and almost passing out, it makes me say w.t.f. when I see people hyping ASrock. I mean SURE, they probably have SOME motherboards that don't catch on fire, but are you really trying to compare them to a Gigabyte.

I really hope these early results aren't indicative of what we're getting, I've been waiting 2 months to finish building a PC to see how this would turn out and I never thought IB would be a downgrade I had assumed it would at the very least have parity with SB. Heck I still haven't found a better deal out there than an i5-2500k + MB + RAM bundle that was available after xmas this year that I passed on.

I guess the only good thing about waiting is that I have an EVGA GTX 680 SC in the mail getting here tomorrow and if I had built sooner I would have ended up paying $600 for a 7970.

So now, there's the fine line between deciding if snapping up one of the last 2500ks on the inevitable bundle clearouts and saving maybe $30 or so over the equivalent IB cpu is the no-brainer way to go or not... if the SB is going to be cheaper, cooler and faster at OC it really does seem a no brainer but it really rubs me the wrong way psychologically to be buying "last gen" stuff for a brand new build. Hell I could have held on to my horses before buying all of the other components and waited for Haswell if I knew in advance this would be the situation.

But hey, hotter IB than expected? I guess I'm glad I have the NH-D14 sitting in a box on the floor then after all.

Oh well, I have to stop over analyzing it and just remember that the CPU is hardly going to matter for what I'm going to use the PC for anyway (gaming / work (software development)) for the next few years from the looks of it at any rate and just start thinking about how I'm going to find the time to play DIII again.

Am I mistaken about recalling this, but are there certain desirable features of z77 which aren't enabled unless you have an IB CPU installed?

I've posted this in other threads, but this basically explains why Ivy Bridge runs hot and why it has a negligible performance increase.
