    A hybrid graphics system is a system with more than one graphics adapter. the i series cpu is just a cpu it has nothing to do with graphics.

    My G73 is a i7 with a dedicated 5870 gpu but its not hybrid.

    The M11x does not have an Core-i cpu but it has two graphics adapters and it is a hybrid.

    Isn't all Core-i processors have integrated GPU bundled together with the processor itself under one shell?

    Only the Arrandale line which are the dual core procs.

    Having integrated graphics as well as dedicated ones mean nothing if there's no actual link between them. Hybrid graphics is the term that designates a link between both an IGP and a dedicated GPU. This link can either swap between themf or performance/battery life and sometimes it can link them for a performance boost.

    AFAIK, not all (if any) of the laptops with Arrandale CPUs and dedicated grpahics are hybrid SLI/Crossfire X systems. I read somewhere that most of them just disable the "Intel HD graphics".

    so you mean they do dont use the arrandale gpu for the switch? thats lame.

    btw, idk exactly what you mean by "sometimes link them for performance boost"... but the people at the launchpad sony z email list had some interesting stuff going about running the 9300 only in a window, for rendering :)

    All of the i cores don't have an IGP on it, but the new Arrandale CPUs have some sort of a chip that process High Definition stuff on the actual INTEL IGP. Therefore dedicated gpu + IGP = hybrid graphic system/ optimus and dedicated gpu + IGP + Arrandale CPUs = hybrid graphic system with HD supported on IGP

    This assumes that the Arrandale IGP is hooked up appropriately. Not all chipsets (specifically the PM55 lacks the appropriate connections) will do so. Doesn't help to carry a second engine in your trunk if you have no way to hook it up to your transmission...

    It all has to do with the hardware and software technology. Almost every mainboard nowadays has an IGP, thats no.1. No.2 now I think you're likely to have 40mm NVIDIA Dedicated GPU to obtain a Hybrid Graphic System because NVIDIA has the technology to switch between those two, I don't think any laptop with ATI Dedicated GPU have Hybrid Graphic System . No. 3, OEMs have to enable their bios to use this technology. No.4 Arrandale chips only accelerate the High Definition stuff on IGP

    My point was that the PM55 chipset does not even allow for the Arrandale IGP to be used. From http://forum.notebookreview.com/del...m55-hm55-switchable-graphics.html#post6049954

    What are you talking about... none of that is true. The current generation of notebook IGPs are in with the dual core CPUs, not the motherboard, and they don't just accelerate HD. Also, it doesn't matter the manufacturing process nor does it need to be a nVidia GPU (though Optimus is nVidia's name for switchable graphics, not sure if that includes hybrid SLI).

    Arrandale processors have an on-package IGP. If an Arrandale laptop has a discrete GPU, this does not automatically mean it supports switchable graphics. That is a wholly different animal, requiring extra hardware in all cases and special software in the case of Optimus.

    All laptops that have discrete GPUs but not switchable graphics have the IGP disabled and nonfunctional.

    I hope this clears up any possible confusion. :D

    Please note that the Core i7-720QM, 820QM and 920XM are Clarksfield processors and do not have integrated graphics on-package. Only Arrandale (Core i3, i5 and i7-620M Mobile dual-core CPUs) have the on-package IGP.

    Switchable graphics is a rarity, hence why Nvidia's "Optimus" made a big deal in the notebook world.

    Intel's new Arrandale CPUs having an integrated GPU on the die does not mean that switchable graphics will magically become largely available.

    Just to add a little something . The intergrated video card is disabled by the BIOS and the second video card ( in my case hd5650 ) is running on low speed. Original it is 550/750 , but on save power is 50/150 . Im running on i5 430m. And that is what everest tells me .

    Yeah, that's normal; PowerPlay (ATI's GPU power management tool) will underclock the GPU when it's idle. On battery and when idle on mains power, GPU-Z informs me that my 5650 runs at 100/150 (550/800 stock clocks).
