What must AMD do? 8800 GT vs. 2900 XT

Alright, here's where things get really interesting. AMD has yet to come out with its 8800 GT competitor, but we've heard some rumors here and there. First, our understanding is that the RV670 based AMD part will not be any faster than the 2900 XT (and will likely be at least a little bit slower). While we can't confirm this, as we haven't heard from AMD on the subject or received hardware to play with yet (in fact if we had, we wouldn't even be able to bring up our speculation). But if we are right, then it makes sense to compare the 8800 GT to the 2900 XT and see what happens.

















Given the performance of the 8800 GT relative to the 8800 GTS, we can expect the 8800 GT to perform on par with, if not better than, the Radeon HD 2900 XT. Our numbers, confirm this for the most part. It's also worth noting that as resolution increases, the 2900 XT really closes the performance gap. This information is quite important. Either AMD needs to pull a rabbit out of the hat and surprise us with performance higher than we expect, or they need to compete with the 8800 GT based on price. We are hearing that the upcoming part from AMD should be competitive with 8800 GT pricing, but we'd need to see availability of the RV670 based parts at prices lower than the 8800 GT to make them start looking worth while. This could be difficult for AMD if NVIDIA hits their target of $200 (or lower for the 256MB version).

Again, none of the info we have on the upcoming AMD part is confirmed by AMD. We are simply speculating based on our best guess at their direction and rumors we have heard. Regardless of what AMD does or doesn't have in the works, it will be difficult for them to afford just another moderate showing. They must either clearly out perform or out price the 8800 GT to stay in the game this generation.

    Yes it has VP2 processor for video decoding. But why would you need a fast gaming card for HTPC? Wouldn't 8400/8600 be a cheaper/cooler solution?

    Thanks for the reply.
    This card looks to be pretty cool running and when not running 3D intensive apps I'm sure power consumption and noise is really low.
    So it might be nice to be able to play a little on a 52"LCD!

    also, if you go with a less powerful card for HD HTPC you'll want at minimum the 8600 GTS -- which is not a good card. The 8800 GT does offer a lot more bang for the buck, and Sparkle is offering a silent version.

    Nothing like cherry picking the games... I don't understand why games like Stalker and Prey weren't tested as the 2900XT has superior performance on those titles, as well as other titles. Seems like a biased test.

    They didn't test The Sims2 or DeerHunter either...
  • DerekWilson - Monday, October 29, 2007 - link

    lol ... stalker and prey?

    we tested quake wars, which is effectively updated prey (id's engine).

    and stalker runs better on nvidia hardware -- when tested properly (many people use demo flybys that point up at the sky way too much rather than fraps run throughs).

    Hmmm I thought ATI's RV630 and RV610 chips both support PCI-E 2.0?
  • Wirmish - Monday, October 29, 2007 - link

    Yeah but it's not worth mentioning because theses GPU are not from nVidia.

    quote:

    The G92 is fabbed on a 65nm process, and even though it has fewer SPs, less texturing power


    G92 has the same amount of SPs and MORE texturing power (twice as many addressing units) than G80. However, 8800GT card has some SPs and texture units disabled.

  • DerekWilson - Monday, October 29, 2007 - link

    well, first, if G92 has those units disabled, then it can't claim them.

    second, NVIDIA would not confirm that the G92 as incarnate on 8800 GT has units disabled, but it is fair to speculate that this configuration was chosen to work out yields on their first 65nm part.
