    NVIDIA recently held their annual stockholders meeting and during it their CEO, Jen-Hsun Huang, reaffirmed that NV30 would be on a .13um silicon process as it was "impossible to make on .15um" and that it would also be here this fall.

    Rumours of it being on any other process appear to be just that, rumours.

    A few notes made from the meeting repeated at Fool:

    Lets hope this is less hype and marketing and more "honesty" about performance if there is such a thing in the 3d market anymore.

    This NV18 transistor count seems a bit strange. Is this investor meeting available as Real Audio?

    Considering NV25 is ~60mil and NV17 is ~35mil IIRC, those numbers are huge leaps. If they're right, we're certainly looking at two DX8 parts; the question is, are we looking at extra pipes/shaders/texture units, as well?

    yeah that transistor counter is strange 31 million more than Geforce3 , 23 million more than Geforce4 . I wonder if they're doing a 4 vertex shader array ala Parhelia?

    The most logical use for the extra transistors would be for increased caches (Or other performance optimizations) and the inclusion of the GeForce4 MX's video features (And possibly also in combination with the .13 micron process in order to make this part very cost-effective).

    I suppose it's also possible that the NV28 is an attempt at a "DX8.5" part, possibly just in case the NV30 doesn't pan out as planned. I doubt the extra transistors would be used for more pipelines or something of the sort, but we'll see.

    Well it's going to be 8 pipelines. And the pixel shaders eat up plenty of real e. So?

    Many people have been stating that the NV30 will have 8 pipelines. I still doubt it, given support for 64-bit color could double (or nearly so) the pixel pipeline size. Plus, there's the addition of many more PS/VS features. I also believe that the T&L power will be massively improved.

    And do not be surprised if neither the R300 nor the NV30 turn out to hugely outperform today's video cards in older benchmarks.

    If NV30 is supposed to be a DX 9 chip, it will have to support the floating point data types that this implies. This means every single blending/calculation stage has to be upgraded from integer to floating point. This can easily eat up ALOT (as in 21 million transistors). Data paths need to be wider too.

    Cheers

    NV30's marketing strategy sucks!

    This card will be speedy as nuts but... well we'll see!

    The NV30 opengl docs say no support for blending in Floating point buffers. The NV guys over at the opengl forum claim that it would have taken too of the tranny budget.

    Is floating point buffer blending part of DX9 ??

    This forum is a bit outdated!

    NV30's only problem is their memory bandwidth! Not that memory bandwidth counts dor everything! See Paraphelia,but still. Otherwise the latest official nv30 specs should make it certain 2 blow everything away on the market! Including your wallet!
