Prey Performance

This OpenGL game represents the Doom 3 engine and is heavy on the texture and z/stencil operations. There are quite a few factors that could cause this game to run poorly on the G84 (clearly G80 has no real issues here). The reduced memory bandwidth or fewer ROPs (which means fewer z/stencil ops/clock) are likely culprits, but without more information it would be hard to nail down the reason we see such poor performance.

The 8600 GTS is able to keep up with its competition from AMD, but lags quite a bit behind the 7950 GT. The 8600 GT isn't able to hold its own against current $150 offerings, but it does at least stay ahead of the 7600 GT which held the $150 line for quite a while.

Both the 8600 cards fall further than other hardware when AA is enabled. Neither of our early generation DX9 games paints an attractive picture of the 8600 hardware. Let's take a look at our final test to round things out.

    sweet review on new tech! thanks for the bar graphs this time! good to know my 512mb x1900xtx still kicks mainstream butt.:) Reply

    Total disapointment :( ... Could even beat up a X1950pro. They really need to sell at $150 otherwise you would be better off buying a X1950GT or 7900GS for $150 to $160. At the current $200 to $230 price you could get a X1950XT 256MB which could destroy it but that GPU needs a good powersupply. Only thing going for a 7600GT is the DX10 support and Full H.264 , VLC , Mepg 4 support but that can be found on even other cards. Reply

    I have been waiting several months for these cards and boy and I disappointed. I figured this month I would get a new PC since April 22 the prices of C2D also drop. My idea was to get a C2D600 and an 8600GTS but after their lack luster performance, my only option is an 8800GTS which is $50+ more. Not a huge difference but I am very compelled to wait until the refresh comes out and then maybe I can get a better deal. I really hate this senario where ATI is down, AMD is down and no competition is leading to high prices and crappy performance.

    Hopefully in another 6 months, AMD will be up to par on both their processors and CPUs. I will be holding on to my current system until then. I found it disappointing that these cards do not come with 512MB of memory but their performance is actually even more disappointing.

    Well, the R6xx stuff from AMD should be out soon, so that's going to be the real determining factor. Hopefully the drivers do well (in Vista as well as XP), and as the conclusion states NVIDIA has certainly left the door open for AMD to take the lead. Preliminary reports surfacing around the 'net show that R600 looks very promising on the high end, and features and specs on the midrange parts look promising as well. GDDR4 could offer more bandwidth making the 128-bit bus feasible on the upper midrange parts as well. Should be interesting, so let's see if AMD can capitalize on NVIDIA's current shortcomings....

    It might be a good idea to read more reviews before writing off the 8600 range.

    Over at , they found the 8600GTS easily beats the X1950Pro and even though the models they tested were factory overclocked, one of them had only a 5% core overclock and no memory overclock and was still well ahead of the X1950Pro. At worst the two cards were roughly even but in many tests the 8600GTS (with just 5% core o/c) was considerably faster. As say in the article link

    New GeForce 8600 GTS Shines
    If you have been waiting for a DX10 video card capable of playing today's games, your wait is over. The GeForce 8600 GTS series GPU destroys ATI's current X1950 series for right around $220.

    So who do you believe? I guess I'll need to read several more reviews to see what's really going on.

    I agree that that review it paints a different picture, but I have no reason to disbelieve it. I mean, they do their testing differently (try to find the best playable settings for each card), but it is what it is... I mean, the tables show the differences in the cards, at those (varrying settings) and so they therefore draw the conclusions they draw, based on that (with card X, I can enable option Y at these frame rates, but not on card Z - at least at the same resolutions). It's not like they tried to hide the settings they used or the frame-rates they got with each set-up. I found it an interesting perspective. ~shrug~

    Anyway, my personal opinion is that they neutered this chipset too much. There looks to be a substantial gap between 7900/8600 and 8800 level performance and the sweet-spot for this price-point would have been right in the middle of that gap... maybe they're planning a 8700 series chipset?

    Thats a funny review. I'll stick to the other 90% that say this fish smells. Reply

    HardOCP's review disagrees with almost everyone else's results and also reads like a marketing advertisement for the product. I wouldn't give their review the time of day. Reply

    They're normally very good which after reading HardOCP's review immediately after AT (whose I read first), I thought I should mention that not everyone found the 8600GTS to be slower than the X1950Pro.

    However, after reading several more reviews on other usually reliable websites, the consensus seems to be that the 8600GTS is well behind the X1950Pro, which does make HardOCP's finding seem very odd.

    I get the feeling that we're going to have to wait until nVidia get their drivers for this card sorted out as I suspect they are not all they could be, which they will hopefully have done by the time the HD2xxx series are launched, then the 8600/8500 cards can be retested and compared with their true competition.
