    It beats the similarly clocked i7 880 in most cases (sometimes HT plays a role), even though turbo is disabled, and even though it has less L3 cache (6MB vs 8MB).

    Not sure why but the whole article seems like a damage control PR from Intel. This could mean two things:

    a) Sandy Bridge is going to be late
    or
    b) Intel is trying to nullify the impact of AMD's upcoming processors.

    a) Why does it seem like damage control to you?

    b) If it is damage control, then have done quite well, haven't they?

    Good point about comparing to current consoles. I'm sure Intel can provide support for OpenCL, but may choose to implement it using CPU rather than GPU resources. Since the CPU and GPU share the same memory subsystem from L3 and out, I can't really see that using the GPU would bring any benefit, whereas the L1, L2 cache hierarchy of the CPU for many codes can. So it will be for compatibility reasons at the behest of their customers if it happens. We'll see.

    I'm impressed by what I see though - much more so than by Nehalem. That said, Bulldozer looks good on paper, and in consumer space it will clearly boil down to market positioning and OEM deals.

    In my professional field, the quad channel memory of the higher end Sandy Bridges will definitely be a competitive advantage.

    It also uses something like 30 times less power than the highest end GPU on the market.

    Llano is coming out in late 2011. It will have to compete with the Intel parts with turbo boosted CGPUs with twice the number of functional units tested here. Of course Llano will win against Sandy Bridge but it may not be so clean vs the 22nm refresh coming in early 2012.



    It'll be interesting to watch. Who would have thought that an Intel IGP would even come close to a console this quickly. I bet you would never have predicted it 3-4 years ago! :razz:


    Maybe you should pinch yourself to make sure you're not dreaming? :)

    I never thought I would either! However this can only mean good things for the PC game industry if we can bring up the Intel range into something approaching respectability.

    I don't remember seeing the "official" benchmark results of an upcoming processor so early before. Mix the benchmark with the AMD's Bulldozer articles from last week and with the Intel's lowered guidance for the third quarter and we have our soup ready :)

    Yes, the results look really promising. It will be interesting to see how AMD's upcoming IGPs will compete with the Intel's future offerings.

    IIRC, SB was said to have a DX10 GPU.

    I am quite impressed by the elvel of performance they have been able to extract. Comparing it to Llano will be interesting.

    Llano shipments to OEMs were supposed to start Q4/2010, release and public availability on Q1/2011.
    This schedule was delayed by about one quarter. So shipments will start Q1/2011, release and public availability Q2/2011. This is not late 2011, and this is about one year earlier than intel's 22nm.

    I'd quess AMD propably has some bulldozer-based fusion out when 22nm intel chips ship on volume.

    What damage exactly is there to be controlled? Isn't BD coming a fair bit later than SB?

    I think it could be stock damage control. The ambiguous, limited benchmarks plus the near zero architectural infos suggest that. They are starting to get hit by the affordable 6 core, and the relatively expensive Clarkdales. Combined that with Bulldozer and Bobcat infos that looks promising, investors might not want to keep the stock.

    Do we have anything concrete on the LGA2011 Sandy Bridge ?

    Well that's one way to look at it, another would be that a third graphics architecture to take into account makes the platform yet more splintered and costly for developers. And Intel finally having a modestly performing graphics chip is just half of the equation - the other being a solid driver set with feature support comparable to the other 2. We're not there yet by a long shot.

    Huh? A few powerpoint slides from AMD won't move Intel's stock. Have you seen Intels' "actual" financial performance recently?

    And all that without ANY AVX optimization added into the software.

    I hope the fix their Hardware Decoder as well since they are consistently using much higher CPU usage then other Hardware decode.

    Anand just did a follow up focusing on the mobile variants, and this comment stood out for me:


    http://www.anandtech.com/show/3876/intels-core-2011-mobile-roadmap-revealed-sandy-bridge-part-ii

    Considering the desktop test was done with such early drivers on a 6 EU part, graphics turbo was said to be broken and Intel are supporting DDR3 1600 as standard, I'd say its pretty safe to double those IGP benchmark numbers for the mobile variants. That's insane, we're talking damn near console performance here. Can't wait till we see what the final hardware can do, laptop gaming just became about 10x more viable.

    How are they packing so much goodness in a 35w envelope!

    Having world-beating manufacturing processes surely helps. I wonder if they'll ever release in-depth architectural details on the GPU though.

    Oh, absolutely and I think the incredibly smart way turbo is managed is a big part of it as well. These chips deliver the power where your machine needs it in order to make the most out of those 35w, the whole idea behind an aggressive turbo mode split between the CPU and GPU just makes so much sense for mobile computers.

    Yeah, I'd really like to see what they've done with their IGP, it surely can't just be trivial tweaks to get the sort of performance increase that they're getting.

    The IGP component sounds real promising, providing a bigger leap in performance than previous generations. It may just satisfy the "average" users gaming needs.

    I took a look at Anandtech's latest chart for mobile processors:
    http://www.anandtech.com/show/3876/intels-core-2011-mobile-roadmap-revealed-sandy-bridge-part-ii

    For higher demanding users, I want to say the 2720QM will be the "sweet spot", as I'm going to guess the price will be a good deal less than the 2820QM, and certainly much less than the 2920XM. The only difference of any significance between the two lower options is the 2MB of cache... I don't count 100Mhz much, even if turbo is engaged.

    Will 2MB cache be of any value, especially considering the likely price difference between the 2820 and 2720 is likely to be $100+?
