Test Settings

We are continuing to use the same Intel Core2 Extreme X6800 that has given us success with testing in the past for this article. The drivers we are using are the same as with the X1950 Pro article, but we've added a few more resolutions for some of the games: 800x600, 1024x768, 1280x1024, and 1600x1200.

Performance Test Configuration
CPU: Intel Core 2 Extreme X6800 (2.93GHz/4MB)
Motherboard: Intel D975XBX (LGA-775)
Chipset: Intel 975X
NVIDIA nForce 570 SLI
Chipset Drivers: Intel (Intel)
NVIDIA nForce 8.22
Hard Disk: Seagate 7200.7 160GB SATA
Memory: Corsair XMS2 DDR2-800 4-4-4-12 (1GB x 2)
Video Card: Various
Video Drivers: ATI Catalyst 6.9
ATI Catalyst Beta (X1650 XT only)
NVIDIA ForceWare 91.47
Desktop Resolution: 1920 x 1440 - 32-bit @ 60Hz
OS: Windows XP Professional SP2

The cards we want to pay special attention to here are of course the X1650 XT and particularly how it compares with the NVIDIA 7600 GT. Given current prices, we should expect to see these cards being fairly well-matched, with one card or the other doing better at certain games and with certain resolutions.

We also added a number of other cards into the performance mix for comparison to get a general idea of where the X1650 XT stands. On ATI's side, we included the X1600 XT, X1800 GTO, X1950 Pro, and X1900 XT 256MB. From NVIDIA, we included the 6600 GT, 7600 GT and the 7900 GS. These cards offer a broad picture of performance for the current generation of midrange and mainstream graphics cards. Some cards, like the 6600 GT and the X1800 GTO, are a bit older than the others, but we included them as a reference for those looking at potential upgrades.

    They spec like this:

    1650XT: 8 vertex Pipes, 24 pixel pipes, 8 Raster pipes, 575MHz, Mem 675MHz X 128 bus.
    7600GT: 5 vertex Pipes, 12 pixel pipes, 8 Raster pipes 560MHz, Mem 700MHz X 128 bus.

    And the ATI card barely holds it's own? I was expecting a walkaway after reading the specs.

    It should be 24 Pixel Shaders vs 12 Pixel Shaders.

    while both have 8 ROP's, it is probably the X1650 XT only has 8 TMU while the 7600 GT has 12 as both are half their flagship derivatives. Ignore vertex amounts those tpyically aren't half and don't contribute to much on the most part to performance it seems anyway.

    X1900 XTX 48 Pixel Shaders, 16 Rasterization Operators, 650MHZ, Mem 775MHZ x 256 Bit Bus
    7900 GTX 24 Pixel Shaders, 16 Rasterization Operators, 650MHZ, Mem 800MHZ x 256 Bit Bus

    The X1900 XTX doesn't walkaway from the 7900 GTX on the whole either.

    Do you guys do other testing that you comment on that is not represented by the graphs? The numbers show a 1 fps difference, yet you use terms like "significant" and "clearly beats". Maybe some median low fps numbers would help demonstrate what you're saying.


    An interesting thing about Oblivion is that it favors ATI hardware over NVIDIA, and this is evident here when we look at the X1650 XT compared with the 7600 GT. In this case, the X1650 XT has a small but significant performance lead over the 7600 GT. Because of this, the X1650 XT is more likely to be playable at 1024x768 than the 7600 GT. This is one case where the X1650 XT clearly beats the 7600 GT just in terms of performance. Oblivion players may want to consider this card once it's available, but only assuming the price is reasonable.

    hey i know i can make an educated guess as to where the x1650xt would end up on q4 benches compared to nvidia's offerings, but i'm still curious why this game was not included in the testing? with quakewars around the corner i think people are still interested in doom 3 engine performance.

    I suppose this name is part of ATI's general trend lately. It used to be that the XT moniker meant the same GPU with slightly higher clocks. Now it seems like the XT parts are a separate family. The X1300XT has nothing to do with the other X1300's (rather it's a rebadged X1600Pro), the X1900XT has more pipes than non-XT members of the X1900 family, and now the X1650XT has nothing to do with the rest of the X1600/1650 family.

    It all makes it a bit hard to choose.

    On page 10 it is mentioned that


    Something that jumps out at us here is that the X1650 XT got slightly better performance than the 7600 GT in both of these games with 4xAA enabled. Without AA enabled, the 7600 GT did better than the X1650 XT in these games. The amount of difference between the performance of both of these cards is about the same with and without AA.

    This is completely going against the bar graphs, specifically the HL Episode One graph. The x1650XT got up and began walking away from the 7600GT without AA, but with AA it tripped and slide into place just behind the 7600GT. At resolutions below 1600by1200 it even began losing by a sizeable margin.

    This paragraph has been tweaked a little bit. In HL2 Episode one the X1650 XT only does better than the 7600 GT at the highest resolution with AA enabled, but in Battlefield 2 it performs a little better over most of the resolutions. Reply

    How many vertex units does this thing have? Reply
  • JarredWalton - Monday, October 30, 2006 - link

    See (updated) table on page 2: it has 8 vertex units, 24 pixel pipes, and 8 ROPs. Basically, lots more power than the X1600 XT. I would guess the pixel pipes are more like R580 pipes (i.e. more shader power, but not necessarily the same as an NVIDIA pixel pipeline in raw power). Reply

    Alright, cool. I keep a chart with stats of graphics cards, so I'm just making sure I have the vertice throughput correct. Other than the useless X1650 Pro, ATI seems to have a much more competitive mainstream line now. There is now more confusion than ever, though. Reply
