Power Consumption

Power consumption at idle is a bit higher than the LGA-1155 options, but that's largely negligible since we're talking about two different platforms here. Power draw under load is slightly higher than the 2600K and a lot lower than the 3960X for obvious reasons.

    Yes the memory is cheaper (about $160). It is not "much much cheaper" (your words) anymore.

    An i7 2600k is $299 at amazon.com and newegg with free shipping and no tax in many states. That is a difference of +15 compared to the speculated price of 285 for the core i7 3820 (so a total of +175 for memory and cpu)

    x79 motherboards cost between $215 to $470 on newegg. Cheapest board with 8 ram slots is $280

    p67 motherboards cost between $95 to $310 on newegg
    z68 motherboards cost between $90 to $340 on newegg

    So you may save $175 on cpu and memory but you are going to spend another $100 ish on the motherboard making your savings less than a 100 dollars. A hundred dollars is not a small amount but we are probably talking all said and done talking about a computer that is going to cost between $1000 and $1500 to build, thus a 100 dollars is between 6 to 10% of the computer price.

    There is a reason to get the x79 chipset, but if you are getting it due to memory, please do it so you can use you 64 GBs of memory instead of a mere 32. Do it for that reason or do it for the 6 core cpus, the pci-e . Do not get a x79 chipset just so you can go cheap on the memory and only get 32 GBs.

    Do not wait another 3 months so you can save a small amount on memory.

    Article: "If you're seriously considering anything in the SNB-E family, the latter [Ivy Bridge] isn't going to matter and the former will be of arguable value"
    piroroadkill: "Anyone who wanted a system of this performance already bought a 2500 or 2600K and overclocked the balls off it..."

    With tri-gate, die-shrink, and small bump in performance, IVB will be a nice setup due to being highly overclockable (I hope!). If SNB can OC to ~4.5 on air (running 4.4 on my rig), IVB with die shrink would hopefully manage something approaching 5ghz (remember, tri-gate does a better job with power flow and reception at lower voltage or higher speeds...). And the pricing lineup has already been leaked and shows fairly similar pricing to SNB launch, so I'm just sitting on my hands until April.

    I've got an i7 940 system and skipped SB and SB-E, but Ivy is my upgrade plan at the moment. SB-E let me down, so I'm waiting till April now. And even then, my i7 940 on SSD does everything I need it to do and FAST..... it's just an upgrade itch that needs to be scratched every couple years (we're suckers perhaps). Reply

    On the chipset block diagram, it says PCI Express 2.0 is branching off the CPU and also the chipset? Shouldn't that be 3? Reply
  • darckhart - Thursday, December 29, 2011 - link

    Yes that confused me a bit as well. Or is that pcie v3.0 only off the cpu and v2.0 off the x79? Reply

    Every time I see the "i7 3xxx" number I get excited and think someone got an early Ivy Bridge sample.

    Then I remember that Intel couldn't even stick to their own naming convention for two generations of the Core iX series. :(
  • p05esto - Thursday, December 29, 2011 - link

    No kidding, that crap pisses me off. Why is so damn hard to come up with a simple naming convention that is intuitive and can be used for decades? Doesn't have to be fancy, they could prefix the convention with some silly name like Pentium, Core i7 or whatever but then give the freaking thing some letter/number designation that clearly shows what is what. I could come up with 10 different numbering schemes without even trying! Reply
  • descendency - Thursday, December 29, 2011 - link

    Yeah. I don't get why they can't just name things like


    i5s... 2300, 2350, 2400, 2450

    i7 (1155)...2500, 2550, 2600, 2650

    i7 (2011)... 2700, 2750, 2800, 2850

    with Extreme chips being 2900 X...

    add in K, X, S and whatever other letters you want at the end

    Then, when Ivy Bridge comes out, change those 2s to 3s... Oh. and when Haswell comes out... make those 3s into 4s... maybe even have an i3 2270 when you want to sell the better binned chips at a higher price.

    I don't get it, why would you sell the i3 2270 at a higher price? The SB is in it's way out.. Reply

    I know it would be expensive, but it would be nice occassionally to get a review of an entire platform and what is possible on it.

    For example, what FPS could you get in 6 monitor setups with 4x GPUs on SNB-E vs SNB. (or something like that)

    How much does extra ram really benefit in those kinds of applications.

    It just doesn't make sense to review all CPUs on even planes because all CPUs are not designed to do what some CPUs are and that's why they are 500-1000 dollars each.
