    With ATI’s introduction of the RADEON 9500 series just a few weeks ago, ATI now has a top to bottom solution on the desktop for the Holiday shopping season. The 9500 cards from its add-in board partners are shipping now and should be slowly trickling into store shelves, while the first RADEON 9500 PRO cards should begin to hit retail within the next few weeks.

    In terms of the RADEON 9700/9700 PRO, we’ve noticed that the third party manufacturers are beginning to release their second generation of RADEON 9700 PRO cards, all of them feature unique cooling solutions that set them apart from the ATI reference design. Tyan was the first manufacturer to announce that it would be releasing a RADEON 9700 PRO card that raised the bar in terms of core/memory clock speeds, but it appears that they won’t be the only card manufacturer with the intention of doing this.

    FIC is working on their “overclocked” part. And while the card probably won’t be officially endorsed by ATI’s certification program, privately ATI is encouraged to see third-party manufacturers doing this. We also saw an interesting solution from Sapphire that utilized heatpipe technology (without the loud fan) that also looked very impressive. We’ll be reporting on these cards in more detail shortly.


    ATI’s take on GeForce FX

    The focus of our conversation with ATI was dealing with the misconceptions brought about by NVIDIA during the GeForce FX launch. ATI essentially feels that the RADEON 9700 is a more balanced solution than GeForce FX, which doesn’t have the bandwidth to perform many of the operations it’s boasting at an acceptable frame rate.

    For instance, NVIDIA is proud to claim that GeForce FX boasts pixel and vertex shaders that go beyond DirectX 9.0’s specs, yet a 400-500MHz chip with 8 pixel pipelines running very long shaders would spend all of its time in geometry, bringing frame rate to a crawl. ATI feels that with RADEON 9700’s multi-pass capability, having native support for thousands of shaders is useless, as the RADEON 9700 can loopback to perform those operations. ATI ran a demonstration of a space fighter that was rendered using this technique.

    As far as NVIDIA’s bandwidth claims of GeForce FX’s 48GB/sec memory bandwidth, ATI states that the color compression in their HYPERZ III technology performs the same thing today, and with all of the techniques they use in RADEON 9700, they could claim bandwidth of nearly100GB/sec, but if they did so no one would believe them, hence they’ve stood with offering just shy of 20GB/sec of bandwidth.

    One other clarification is in regards to DDR2 memory support. Late last week rumors were floating around that ATI’s DDR2 demonstration wasn’t actually running as DDR2 memory. ATI reiterated that the RADEON 9700 memory controller does indeed support DDR2 and that was the memory type used in the demonstration board.

    Pah isso é tudo tanga

    "The GeForce FX will outclip rival ATI Technologies' Radeon 9700--the fastest graphics chip available now--by 25 percent to 50 percent in speed."

    "ALL OF UR SLOTS ARE BELONG TO US" company representatives said

    :P

    "The first two versions of the new chip, the GeForce FX 5800 and 5800 Ultra are in production. They will be available in January and will be priced between $399 and $499 at retail."

    Guardem o guito ou torrem.no já.


    O problema é que depois começam a aparecer rumores destes

    "Finally, it will be interesting to see what ATI is up to come February. Word on the street is that ATI’s follow-up to RADEON 9700 PRO (codenamed R350) has taped out recently and will be marketed under the name RADEON 9900. We’ve heard conflicting reports on its manufacturing process, we naturally assumed it would be a 0.13-micron part, but we’ve also been informed by another source that the design is 0.15-micron.

    In any case, R350 will certainly boast higher clock speeds and performance, so GeForce FX could be in for quite a battle if it slips any further."

    o problema não são esses rumores

    são estes

    lá vai a minha gf4ti4200 durar mais uns tempos do que era previsto
    depois na altura ve-se o que é melhor e depois compra-se

    Granda noia... fonix... então quer-se dizer que tomei a decisão correcta, não despaxar a ATI já a espera da GFFX... nice! :P

    Bem, isto quer dizer que a ATI tem caminho aberto para lançar a R350... será que a NV30 não xegará tarde?

    Bem isto ta a virar alto circo

    A Fx não suporta Displacement Mapping

    "I now wonder if Displacement Mapping is “must be” function of the DirectX 9.0. If it is, Nvidia may not be able to claim the DirectX 9.0 full hardware support for the GeForce FX VPU."

    Se bem que tb parece que não serve para nada hoje em dia, mas para o rei do marketing, sempre é mais uma espinha....


    Que a FX vai ser rápida ninguem duvida, agora será que quando ela chegar será suficentemente rápida que justifique/compense estes 3/5 meses ainda de espera? Isto tudo supondo que a ATI fica quieta.

    Tinhamos o vapourware, agora com esta jogada da nvidia acho que temos que arranjar um novo nome para isto, para produto que existe mas não existe, que sabe que vai existir mas ninguem sabe ao certo. fxware?
