Nv47: 24 pipes. Spring 05

    "While NVIDIA remains extremely tight-lipped over its future products,
    it is known that the company is readying its code-named NV47 visual
    processing unit, a massively revamped GeForce 6 architecture with 24
    pixel pipelines. The NV47 is expected to be released sometime in
    Spring, 2005, but it is unknown whether NVIDIA is ahead, or behind
    ATI's R520 product.

    The status of NVIDIA's future architecture code-named NV50 is also
    uncertain: some reported recently that the chip had been cancelled, but
    officials decline to confirm or deny the information."

    I don't plan to do anything big in terms of upgrades to my PC until probably
    2006, so I can imagine how much faster the new box will be by then compared
    to my current machine which is now 15 months old! These sorts of
    developments are promising.

  3. Ya know what I want? I wan't two Vid cards. 1 ATI, and 1 NVidia. I wan't
    them to both be < 50$, have 64 pixel pipelines, use GDDR4 at 1.5ghz and run
    on the not-yet-conceived USB 3.0 interface that supports 800Gbps; this way I
    can swap them out whenever I need to in no time at all. Shit... I could even
    carry my USB 3.0 vid cards on my keys... but then I'd look like a real nerd
    and it would really suck if I lost my keys.

    Eh.....hmmm... anyway.... I'm thinkin ATI's gonna win next round.

  4. Err, and CPU's still only have 9 piplines.
    Nicholas Buenk, Dec 10, 2004
  5. We should have got 32 pipes with a 600MHz core clock and GDDR3 @

    Well with IBM manufactoring nVidia's GPU and Sony pumping in a fortune
    with there PS3 partnership, it should be interesting. Just imagine some
    of the resources and technologies available to nVidia now from Sony.

    Perhaps ATI needs AMD to do some of the fab work for there GPU :)

    Nvidia's next gen PC GPU, whatever it is (not Nv47, but either NV50,
    NV55, or NV60) will probably have 48 pipelines, at 600~700 Mhz. on 90
    nm or 65 nm. just guessing.

    CPU's generally only have one pipeline,
    maily because they generally operate in a
    serial manner. The stuff a GPU operates on is
    highly parallelised so going with multiple
    pipelines makes sense.

  9. The 486 was the last CPU to have one pipeline....
    The Athlon 64 has 9 the Pentium 4 7. Still the more piplines you have the
    harder it is to push up mhz. And if GPU deal with more parallel data than

    Out of interest. without me going and looking it up, how many pipelines on
    the AMD XP CPUs?

    Now, there's a convincing argument...

    The A64 has two pipelines, one for integer
    and one for floating point, (cite:
    http://sandpile.org/impl/k8.htm) what you are
    referring to is pipeline stages, which is not
    the same as a pipeline.

  15. The same number, the 64 just has a modified instruction decoder, ondie
    memory controller and 64 bit and more... It's mostly the same as the XP.

  16. What is the difference?

    A pipeline is just that. Each pipeline can have several operations going on
    at once, each is a stage.

    However, according to the AMD site, the Athlon XP has 6 pipelines, not
    stages, 3 floating point and 3 integer, and the site that 'factory'
    references does not say anything about how many pipelines are present, only
    about the number of stages.

    I can't find anything on the AMD site that says how many pipelines the
    Athlon 64 has.

    Its not an argument. Anyone can find out for themselves.

    No doubt they are blowing smoke up ATI's collective arse. But interesting
    reading nonetheless.

    I wonder if the Register and other reports are simply miscontruing the
    two chips. I.E., there is no NV50 yet, but a 47, or that an early
    revision of one of the chips was scrapped (sort of like what happened
    with early R500 development or what NVIDIA initially did with the NV40).
