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.

1280x960 is actually in keeping with the 4:3 aspect ratio. 1280x1024 actually stretches the height of your display although it's a little hard to tell the difference.TheInvincibleMustard - Friday, October 7, 2005 - link
The actual physical dimension of a 1280x1024 screen is larger than a 1280x960 if the pixel size is the same -- there's no "stretching" of anything, as 5:4 is just more square than 4:3 is but you've got more pixels to cover the "more squareness" of it.-TIM

It would be more of a squishing if you ran 1280x1024 on a monitor built for 4:3 with a game that didn't correctly manage the aspect ratio mapping.The performance of 1280x1024 and 1280x960 is very similar and it's not worth testing both.

True enough, but most 17" and 19" LCD monitors (the monitors in question in this line of posts) are native 1280x1024, and therefore no squishing is performed.I do agree with you that it is redundant to perform testing at both 1280x1024 and 1280x960, as those extra ~82,000 pixels don't mean a whole lot in the big picture.

Interesting... I had always assumed that 17" and 19" LCDs were still 4:3 aspect ratio screens. I just measured a 17" display that I have, and it's 13.25" x 10.75" (give or take), nearly an exact 5:4 ratio. So 1280x1024 is good for 17" and 19" LCDs, but 1280x960 would be preferred on CRTs.TheInvincibleMustard - Saturday, October 8, 2005 - link
By Jove, I think he's got it! :D-TIM

That might explain why I can't tell the difference. Thanks much for the info.intellon - Friday, October 7, 2005 - link
bang on with the graphs in this article... top notch. I guess the difference in performance of these cards make it less congested.On another note, I was wondering would it be too much hassle to set up ONE more computer with a mass sold cpu (say like the 3200+) and a value ram and just run couple of the different game engines on it, and post how the new cards perform? You don't have to run this "old" setup with every card ... just the new launches. It would be much helpful to common people who won't buy the fx55.
I for one, make estimates about how much slower the cards would run on my comp, but those estimates could be much better with a slower processor.
I understand that the point of the review is to let the gpu free and keep the cpu from holding it back, but testing with a common setup is helpful for someone with limited imagination (about how the card will run on their system) or not so deep pockets.
Of course you can just go right ahead and ignore this post and I won't complaint again, but if you do add such a system in the next review (it just has to be run with the new cards) I'll be the one who'll thank you deeply.

One other factor in making a choice is that there are no ATI X1000 series cards available at this point. Once again, every review site covered a paper-launch, despite railing on it in the past. No-one is willing to be the first to be scooped and say "We won't review a product that you can't buy".I have an ATI card myself (replaced a recent nVidia card a year ago, so I've had both), but right now I'm pretty sick of card announcements for cards that aren't available. This smacks of ATI trying to boost its earnings or its rating in the eye of its shareholders, and ignoring its customers in the process. It's going to be a long time before I buy a graphics card again, but if I had to choose a vendor based on the past two years, both companies' reputations fall far short of the customer service I'd hope for.
