ATI's X1000 Series: Extended Performance Testing

Doom 3 Performance
NVIDIA hardware just runs Doom 3 better than ATI hardware, and as we saw before, the case hasn't changed with the new R/RV5xx GPUs from ATI. The light and shadows in Doom 3's engine play a huge role in the game, and the algorithms and API (OpenGL) just tend to favor NVIDIA's architecture and drivers.
The 7800 GTX and 7800 GT both out-perform the X1800 XT across the board without AA enabled. The 6800 GT manages to run faster than the X1800 XL, and the 6600 GT leads the X1600 XT by huge margins. The X1300 Pro stops being playable after 1024x768, which really doesn't bode well for a $150 card.
Performance falls off faster with AA enabled, but that is to be expected. The 7800 GTX and 7800 GT just increase their ability to out-perform the X1800 series here, but the X1600 XT becomes more competitive with the 6600 GT this time around. Of course, neither one really does that well at 1024x768 with 4xAA - 44 FPS is playable, but just barely.
Enabling AA drops performance by a similar proportion on the X1800 and 7800 series parts at high resolutions, with low resolutions favoring NVIDIA hardware. In another twist that spits in the face of the trends that we have seen, the X1600 XT handles AA much better than the 6600 GT and shows a lower percent impact than most of the other cards in the test.

These points were brought up about the first article too. It's a big improvement, I agree, but it's still not to the level that this site was founded on.DerekWilson - Friday, October 7, 2005 - link
We already commented on the FEAR Demo -- we won't test a game that doesn't show shipping performance characteristics. We are working on getting our hands on a prerelease copy of the shipping game for testing.We have had black and white 2 in house since it became available at best buy (as today is the official US launch, we got it a couple days early). We just haven't had enough time to finalize tests for it.
We will look into the recently released call of duty 2 demo among others. I agree that we could have done things better, and hopefully our coming follow up will hit all the points people want covered.
If you have any other suggestions, please let us know -- we will try our best to include them.

As for other suggestions, how about some games other than FPS or FPS-view (EQ2) style games? A driving game like NFS:U2 or colin McRae Rally 2005 would be an excellent addition. Then you should have some sort of flight/space-sim, like maybe X2. And a roleplaying game that isn't viewed from a first-person perspective. By including games that have a totally different style of graphics, you'll get a better idea of how well the card performs. X2 for instance would require totally different graphics performance than Half-Life 2.I know some of the games I've mentioned don't have a benchmarking mode, but use FRAPS to get the average framerate. And the minimum framerate. In fact the minimum framerate is more important than the average so you should include it as a matter of course in *all* tests, even to the point of dropping the average framerate if you don't have space. No one is too bothered if the average framerate while playing is 45 or 50fps while playing a game, but the difference between minimum framerates of 20 and 25fps would definitely be noticeable. I'm sure others will agree.
This (and many other) site seems to think FPS games are all people play, but a lot of us play games from all genres, so including them would be useful.

I support the use of X2: The Threat as a benchmark, I also support the use of shipping games to compare numbers, so Anandtech should benchmark Black & White 2 as it is now available, plus Call of Duty 2 & Fear when they become available.bob661 - Friday, October 7, 2005 - link
Even though I found the original article very informative (I guess I can read well), this one was much better. The bar graphs don't show how the performance goes down as you raise the resolution and turn on the eye candy.zmanww - Friday, October 7, 2005 - link
what no Overclocking?come on I want to see that this baby can really do.
Peldor - Friday, October 7, 2005 - link
I don't think the usual overclocking utilities are working for the X1x00 cards yet.DerekWilson - Friday, October 7, 2005 - link
this is true -- we wanted to test slower versions and couldn't because of this.also reference board overclocking isn't always the best indication of retail board performance.

Would be nice to see some analysis of ATi's SM3 implimentation, with SM2 vs SM3 benchmarks in the games which do support SM2 and SM3 paths.tfranzese - Friday, October 7, 2005 - link
From the article:I think the analysis and the conclusions up to this point have been far short sighted. Seems that the games that are using SM3.0 are taking considerable advantage of the new architecture. The Tech Report, Hexus and others were able to show that much.
