    130W- compared to the 2600k's 95W, including on die graphics. Yeah, that's a big jump in TDP.

    Those memory bottlenecks get worse with more cores. It's pretty obvious. There's a good reason why Sandy Bridge E has a quad-channel memory controller.

    Considering that I been wanting to build my first desktop for awhile and I have been waiting for all sorts of info about Haswell, the more I know, the less I even want one.

    If GT3 is all about perf/watt, does that make the GT2 the "enthusiast" iGPU? GT2>GT3? wtf Intel, WTF!

    Not only that, no GT3 in desktop OR notebooks. Again, what the heck? They got a deal with Nvidia or something? I would not be surprised about that.

    To sum it up, all I cared about Intel was its iGPU.

    There are 3 GT3 models.
    Regular laptop quadcore+GT3.
    Regular laptop dualcore+GT3.
    ULV laptop dualcore+PCH+GT3.

    GT3 is only about performance/watt in the ULV.

    How much power do you think my CPU is drawing?

    I think it might be a tad more than 95w.

    http://www.legionhardware.com/articles_pages/sandy_bridge_e_memory_performance_guide,8.html

    Go through that, and tell me again about how bandwidth starved 6 cores are.

    Difference between DDR3-1333 and DDR3-2133
    Winrar = 23%
    Photoshop = 8%
    x264 = 8%
    Dirt3 = 0%
    Just Cause = 0%
    The Witcher = 0%

    Someone with leaks of performance some A0/A1 revision chip?:)

    Why would your overclocked powerconsumption be relevant in terms of what SKUs Intel can make?

    Haswell is in PV/PRQ stage. So A0/A1 would be outdated.

    Where is the info about the GT3 in notebooks being higher performance parts than the ULV GT3? I have not seen that.


    But, on the Desktop side of things, looking at the artic leaks here -> http://wccftech.com/arctic-cooling-...50-cpu-lineup-core-i73980x-confirmed-lga2011/

    I wonder what a cheap(EDIT:low clocked) HSW cpu will cost? Mainly the Core i7-4765T.
    What's comparable in price by IVB terms right now?

    I might go haswell if the cpu+mobo combo doesn't cost an arm and a leg...
    And I also hope the "1150 low power" and "1150 standard power" sockets don't mean anything other than the TDP's of the chip.

    It'd be a miracle if it was representative of the final product. Can you imagine getting a flawless Haswell back from tape-out.

    At this time they better be close, if not flawless. Mass production will soon start.

    Was talking about A0/A1.

    So, I believe, someone must have some ES to show :)...I saw only one old benchmark of first ES at Chiphell, but is it long time ago..:(.

    Honestly, I don't want to know ahead of time for Haswell. I want it to be like opening a Christmas present.

    But that isn't going to happen.

    "The raw performance of integrated GPU, in single-precision FLOPS, can be calculated as follows: EU * 4 [dual-issue x 2 SP] * 2 [multiply + accumulate] * clock speed.
    For example, the HD Graphics 3000 is rated at 125 GFLOPS,[55] which is consistent with the formula (12 * 4 * 2 * 1,300 MHz). HD4K = 16EUs x 4 FMA per EU x 2 issue @ ~1.1GHz = 282GFlops."~from wikipedia

    Can someone please dumb this down for me completely? I seem to not getting the HD4000 GFlops on my own. (16*4*2*1.150MHz = 147.2)
    But its probably because HD3K is based on SNB and HD4K is based on IVB, meaning that IVB have different "FMA's" and "issues" or something...and making the info in wiki above, incorrect also?

    Any help would be greatly apretiated!

    Old news and outdated. And you forget the source btw.

    It proves that the socket can handle far more power consumption.

    Every single board out there? Or your board?

    Considering mine is a low-mid range board... anyone who doesn't use absolute crap for components.

    You are missing a critical enhancement with Ivy Bridge.

    Sandy Bridge has a math unit with every FMA vector pipeline. Ivy Bridge takes that math unit and adds the ability to execute lot of the common instructions the FMA pipeline can do. So it effectively becomes like having 2 FMA units.

    So you gotta go and double your number again for Ivy Bridge.

    No, only the mobile quad core and ULTs are getting GT3. The regular dual cores don't.

    I got it from the wiki article. But thanks. Now lets see...

    So for IVB HD4K it would be 16*8*2*1.150MHz = 294.4GFlops?

    And a theoretical HSW HD4600 is 20*8*2*1.200MHz = 384GFlops

    So, about a 30% increase from IVB, I guess it does work.


    Now for the GT3 is a bit theorical even more, unless I missed the frequency of them?
    Ahh, lets just see.

    40*8*2*500MHz = 320GFlops
    Likely scenario -> 40*8*2*600MHz = 384GFlops (Higher than a 6620G, 355.2GFlops)
    40*8*2*700MHz = 448GFlops (Higher than a 7560D, 389.1GFlops)
    40*8*2*800MHz = 512GFlops
    40*8*2*900MHz = 576GFlops

    Its seems that no matter how you look at it, HSW iGPU won't be much competition against AMD's, what AMD already had for a year. Hopefully 4th gen Intel graphics on Broadwell will bring a bigger impact.

    Kinda saddened really -.-'' Is there any info about actual architectural changes on the iGPU of Haswell? Not just rumors? Seems HSW is just IVB iGPU's+4 EU's.

    I don't know a lot of people that would couple a high end cpu with a $55 biostar motherboard...

    Search Anandtech for Haswell IDF coverage.

    I'm thinking it'll end up at ~1GHz for the quad core GT3. With 640GFlops, that's approximately double what a Ivy Bridge GT2 running at 1.3GHz achieves. Since 20% gain in average will be enough to match Trinity in the mobile, they should be able to do it with GT2 alone. Of course they'll still be behind for Desktop.

    Yes, there are cases where the HD 4000 is more than 20% behind but Haswell increases more than computational performance as well. Like doubling fixed function pipeline performance, and increase in texture performance in some scenarios up to 4x. Also adding the Resource Streamer to reduce driver bottlenecks. Those should help a lot to close up in the weak areas.

    I don't know... people that don't need the additional connectivity?
