    I have just made a small comparison between Radeon 7000 and
    GeForce 600 series graphics cards
    :

    http://gpus.herokuapp.com

    The factors taken into account:
    die size, manifacturing process and
    the market segment targeted by each gpu.

    I do not know how good I distributed the different
    chips to their respective segment. Correct me
    if I am wrong.

    Conclusions:
    It is mix of gpus made in old 40 nm process
    with the new one 28 nm. The lowest segment is occupied
    by 40 nm parts and the rest of the segments mainly by 28 nm parts.
    GeForce has smaller die size of its top chip, GK104, compared
    with Radeon top chip, Tahit. That allowed NVidia to target
    lower segments with the same chip. In this way NVidia
    reduces the producting of a separate product line.

    Questions:
    I am just wondering if the integrated gpus takes more
    market share, will we see just 1-2 new chips per
    generation instead of 3-4 before?
    What do you think?

    Regarding your questions, I think that if and when the performance of integrated solutions gets closer, the dedicated cards would either have to: Get more expensive/powerfull, or be released more often. I think this because they need to keep the gap between iGPUs and dedicated ones big enough so people will keep wanting to buy new cards instead of relying on the intergrated stuff. Also, at some point most people will perhaps be content with the power that is provided by iGPUs alone, regardless of how much more powerfull dedicated cards are. I still see enough graphical power(or plain parallel power for that matter) needed in the near future for people to want dedicated solutions though.

    I think that as soon as consoles only use integrated GPUs, the market for dedicated GPUs might be in trouble.


    Regarding your site: I think this kind of thing can be a powerfull tool. However, in order to reach any real cool conclusions, you should think of including as many specifications as you can, like poweruse, clocks, amount of transistors, Gflops, price,and perhaps even some real world benchmarks.

    That way, you can compare a lot more things and come to cool conclusions, like, efficiency per transistor, or flops per area.

    Just a thought:)

    Curious as to what you might find!

    I agree with you.

    I tried to include up to now factors that are undisputable:
    die size, core count, manifacturing process. They are
    more oriented to the cost rather than the income. I think
    in Techpowerup.com there is a good set of reviews that
    include enough benchmarks. The price of the products
    is usefull. Unit sales is great factor. Unfortunately, only
    the manifacturers know the exact number of sales.:)

    Don't forget GK 100, it is not for consumer cards, but still works as a GPU. There are stil 3-4 chips per generation tho. (Tahiti, Pitcairn and Cape Verde from AMD and GK100, GK104, GK106 and GK107 from Nvidia) but the performance of integrated solutions is eating into the lower end cards.

    Consoles starting to use integrated GPUs will not change a thing in my opinion, as they already get outpaced rather fast by desktops anyway. 360 uses a modified ati x1900 and ps3 a modified nvidia 7800, both of these cards are underpowered today, and was mid range round launch of the consoles. If the integrated solutions start getting into mid range territory they could get included in consoles.

    Another interesting thing with GPUs and consoles is that with both vendors pushing a working multi GPU system, GPU upgrades for the possible integrated chips can be done (the N64 had a ram upgrade available that some games required) this would extend the life of the console, and the limited hardware con-figs possible (with or without GPU upgrade) would make it easier get most of the performance form the multi GPU solutions

    Just my thoughts on the subject
