    So now that we have established that the HD video is broken (unless you like frame-skipping :>), how about the 3D and some games? I like Intel (I own many) and give them the benefit of the doubt on CPUs, but not GPUs. Why? Track record, from Vista issues to reported game perfornace and compatibility! Let's see the numbers....

    Not 100% sure, but don't the new Lenovo Thinkpad X200 have Centrino 2? Some people have gotten their hands on units and reviews are popping up. Reply

    I'm glad this feature is finally making a real push in the market. And it doesn't get any lower power than an integrated Intel GPU. All I want on the go is web browsing, DVD playback and Office. If I'm playing a game on a laptop, its with the power cord plugged in. Reply

    Seriously, does anyone know when G45 based boards will finally hit the market? The article mentions that GM45 laptops should be out within 30 days, but it seems like I've been waiting for what seems like 6 months for the G45. Reply

    I think your package info for the chips is wrong. 35mm^2 is smaller than the size of your pinkey fingernail. I think you meant to say 35mm x 35mm. That would be 1225mm^2 or 1.225cm^2. Reply

    actually, that should be 12.25cm^2 Reply

    Hi Anand,

    you're writing:

    "Note that here, while the voltages dropped vs. Merom, maximum current draw actually went up to 44A from 41A. This could be due to greater leakage, the higher clock speeds offered by Penryn or simple inexperience with the 45nm process compared to Intel's tried-and-true 65nm process upon its release."

    It's much simpler than that. P = U*I, so if P=const (35W) and V goes down, I has to go up.

    Not so much "new platform" as "new marketing opportunity for OEMs".

    I don't mean to knock Centrino - the original platform really did move the wireless revolution along.

    Centrino2 however brings nothing new other than upgraded (or downgraded!) components.

    I think AMD went the right way by including graphics requirements in their http://game.amd.com/us-en/amdgame_whatis.aspx">AMD GAME! platform, but only time will tell. Centrino is such a strong brand name it might be hard to top. It would be nice to see a gaming-based Centrino.

    It'd be nice if you could also get a similarly configured system with the 2.53GHz T9400 and P9500 to try to ascertain the realworld battery-life benefits between the 35W and 25W TDPs. (I'd wish they'd just call the 25W TDP parts Medium Voltage, Mxxxx parts, which makes it more intuitive where they belong compared to LV and ULV parts.)

    And maybe a comparison between a 2.4GHz SL9400 and a 2.4GHz P8600 to see how big a difference the loss of 3MB of L2 cache is. With a 1066MHz FSB, it probably isn't a big deal.

    Will new 25W CPUs also work in Santa Rosa boards? (drop-in replacement possible?) Reply

    This revolutionary technology runs Vista like a champ but is not supported when it comes to apple and the cult people!

    Shame on Intel for the crappy launch... and the whole lot of hype and noise about the "new platform" seems out of place to me, seeing as it is simply more of the same old.

    The new integrated GPU is really the only big change to me, but I already have very low expectations for it. Nothing unusual, we're already used to Intel's GPUs being inferior to nVidia/ATI. Shame that the "platform" requires an Intel chipset.
    The dynamic switching between discrete and integrated GPU has potential, but then again it may be completely useless if the discrete GPUs are able to tune down their power drain when used only for 2D or Aero.

    I'm not too excited about detailed specs or performance numbers of the platform itself - "it's good enough" and "it's better than the old one" is all most people need to know and understand really.
    I am much more interested in knowing what new things the OEMs are cooking. Will we finally get some decent GPU in a tablet, will we get multi-touch screens, will we get something like AMD's idea of 16x pci-express connector for external GPUs, etc... all things that are quite unrelated to Intel and the new platform launch - they have been possible all along with the old platform and I'm a bit disappointed they are still being delayed.
