    will haswell be compatible with a z77 board?

    No. Haswell gets a new socket.

    As for cores:
    4 vs. 2 I get, 6 vs. 4 I kind of get. But 8 vs. 6?

    Looking at Xeons, the highest clocked 6-core runs at 3.3 GHz, the highest clocked 8-core at the same TDP runs at 2.7 GHz. Even assuming perfect scaling that is a measly 9% performance advantage with the 8-core chip. Not worth it.

    That is a sick rig my friend. How did you get to 5Ghz on that hexacore chip? What CPU voltage are you using to get to 5Ghz stable...

    Hi, my first post here. You probably already seen this news about Ivy Bridge Xeons spotted in the wild. They do seem to be 10 cores / 20 threads chips so I see no reason for the Ivy Bridge E not to have at least 8 or even 10 cores active. I guess 10 ivy bridge cores could successfully compete with the mainstream Haswell...

    And considering that Intel will probably start to roll-out the big guns Ivy Bridge Xeon first, that is the 10 core versions, we will probably soon get the new Ivy E on desktop just in time to compete with Haswell.

    edit: anyhow, what I mean is that Intel seems to have enough headroom to make Ivy Bridge E appealing to professionals and enthusiasts by virtue of its multicore capabilities until Haswell E shows up in 2014.

    Well, if it were an -E series, there would be overclocking opportunities, especially with custom LC. If I could afford such a rig, I would be able to afford a good custom H2O cooling setup and be able to push higher clocks. Plus, IBV-EP is actually looking pretty good for 10 cores on an ES sample, to bad it's not going to happen. Again though, this is in the context for F@H, which is highly parallel.

    Xeon is faster in MT threaded benchmarks then desktop EE and draws less power to boot. So what are you raving about? More cores is always a better way to extract MT performance than raising frequency, which hits a limit pretty fast. It even draws less power than 130W desktop processor. 150W vs 130W and still less power used. And all Xeon had to do to accomplish it is to give up a measly 200MHz. EE should be fully unlocked silicon like they used to be, now the best desktop part is a core harvested server silicon. PATHETIC.
    Don't rely on TDP it says nothing about actual power use, just check that article. That 2.7GHz Xeon probably draws way less power then that 3.3GHz 6 core as even 3.1GHz 8 core draws less power than 3.3GHz SB-E. Granted they named it differently but I don't see any further differences.

    There must be some correlation though, otherwise why not spec every desktop CPU to 140W or 35W and then if/when people complain about the matter they would just fall back to "TDP says nothing about actual power use".

    It's just a value that should not be exceeded, Intel was just being very conservative with that Xeon, as we see it uses less power than 130W TDP desktop chips. Often higher TDP parts use less power then lower TDP parts. So you can't just compare TDPs between CPUs even from the same manufacturer and draw conclusion about actual power use. If a CPU uses more power then its TDP for an extended period of time then something is wrong. So in theory Intel could spec every desktop CPU to 140W TDP because that value wouldn't be exceeded. But why install cooling solution that can dissipate 140W of power if all you need is 65W/77W/95W.

    I'm not surprised. I think that six-core ivy is going to have trouble keeping up with a quad Haskell in multithreaded code.

    Will the 3980X have a TDP of 200W? :awe:

    Oh, and tweakboy must be pleased.

    maybe if they give it stupidly high clock rates.

    For some reference, the 8 core Xeon E5-2687W is 3.1GHz base 3.8GHz Turbo and is 150W TDP

    12 cores is too much. I'll be going Haswell instead. No way can the clocks be decent with 12 cores. Now if they have a 6 core version that clocks high, then that would be good.

    Son of a monkeys uncle,i just installed a 3930k today and intels already phasing out the 6 core for a 8 and 12 core model.:awe: God is this chip gonna look belittled.:|

    Wonder if that means that perhaps the 6 core ivy-e will be at a lower pricetag then current sb-e offerings?

    Still love my 3930k even if intel wants to make it look like a paper weight next to the 12 core behemoths coming out this year.:)

    12 core is for Xeon lineup only. I wouldn't expect more than 8 cores for desktop, if even that.

    LOL,i saw the 8 core xeons on newegg and was tripping out at their insane price tag,i honestly swear the people posting their reviews on newegg are simply stroking their e-penis.

    Cheapest 8 core xeon currently is the 2ghz E5-2650 at $1,100:eek: Those 12 core chips are gonna be a whopper of a price tag.

    6 cores vor Ivy-E probably. I just hope they increase clocks a bit. 4 GHz baseclock for the best model or so.

    If the 6 core Ivy-E's have good temps (unlike current models) then they might OC like absolute crazy. It might make sense in that case to get an Ivy-E instead of haswell if you are already on 2011. I'm dying for this stuff to hit the market.

    Very,,,


    I saw that Sandy E will get a 8 core 16 thread.
    Ivy Bridge gets from 6 core to 12 core. Desktop 12 core that is.
    There will be Ivy Bridge in 3Q 2013 with a desktop edition you get 6core 8 core 10 core and 12 core. There will be a ivy bridge E with more then 6 cores for desktop..................
