ATI's Catalyst 3.8 Drivers: ATI Sanctioned Overclocking

Final Words
In light of our final testing, it is very important to mention that we did not shut down the system and let the card cool down between each test. It is therefore possible that we didn't see the highest potential performance gains we could have from each game. Ideally we would have done this, but we've only had these drivers for a day, and we didn't know the extent to which continued use would affect the cards performance. Of course, this isn't all bad.
The fact that this card overclocks itself based on temperature allows at lot of room for differentiation between different R360 based products. The type of cooling card makers decide to strap on these chips will directly affect how much performance a user can get out of the overdrive feature. Since this doesn't involve doing things like tweaking core and memory clock speeds at the OEM side, more manufacturers can offer cards that have the performance of overclocking with the rock solid stability ATI’s overdrive feature offers. All that's necessary for more consistent performance gains is a better cooling solution.
Of course, we don't know how intensive cooling will affect maximum performance as we don't know the upper limit of ATI’s automatic clock settings.
Overall, these drivers offer some very good UI enhancements, and the overdrive feature does provide tangible speed improvements, and hopefully their VPU Recovery feature will save some people the trouble of blindly rebooting their systems when they lose video. Unfortunately, we didn't see the image quality fixes for TRAOD and Neverwinter Nights that we wanted. Hopefully ATI will not stand by and hope enough people think NVIDIA’s image quality is poor enough that the issue with their own product can go ignored.
Of course, the speed gains from this driver release are not astronomical, but when we add these small gains to the gains already seen in the 9800XT, we can definitely say that this is a solid, well rounded, fall refresh product from ATI. We applaud ATI for trying to go in new directions to enhance performance, and we hope to see plenty of cards from their partners that take advantage of the opportunity presented to them by the XT line. Even so, we are still standing behind our wait and see recommendation with respect to purchasing a card intended for use with the coming DX9 games.

#3 has the best comment, is there a way to get the info of the Core/Mem speed being used? It just seems that outside of the OpenGL benches, the increases were too small to really know if Overclocking was happening or not. IOW, the gains were small enough to fall into statistical anomaly.Certainly any gain is good, but I was able to acheive better improvements from overclocking on a number of video cards, either ATI is being really conservative(which makes sense since they have Warranty concerns) or the Overdrive isn't working(possible, but I'd choose conservatism as the reason).
I'd also be interested in the results of using exotic cooling(not that I'd use it). It would be especially interesting to see if the Overdrive feature is able to recognize Graphic Corruption or whether it is solely concerned with temperature.

The XT is how the original 9800Pro should have been released 6 months agoAnonymous User - Wednesday, October 8, 2003 - link
ZERO DX9 games???Then please explain how it is possible that I have a DX9 game on my machine at the moment. (A TWIMTBP even :-)
But if the rare DX9 games at the moment are not the ones you are interested in, then indeed it is better to wait. (if your card is still fast enough for the current DX8 games).
But if you do need to buy a new card at this moment, (maybe the old one broke) then the choice is very clear.

the conclusion didn't say ati was a bad card to buy, it just said its a bad time to buy a card.Anonymous User - Wednesday, October 8, 2003 - link
You're an idiot #8. HL2 won't be out for months and there are basically ZERO DX9 games out. Therefore, it'd be stupid to buy a card now based on basically no data. And no, ShaderMark 2.0 is barely hard data.Anonymous User - Wednesday, October 8, 2003 - link
Lol #4. ;)I am extremely perplexed myself with the conclusion. Specifically, the last sentence:
"Even so, we are still standing behind our wait and see recommendation with respect to purchasing a card intended for use with the coming DX9 games."
Hello? Anandtech? If you are buying these cards with an eye to DX9 performance, the choice is clear. ATI. At best, nVidia "optimizations" might get DX9 performance on par with ATI's. At worst, it's about 50% of ATI performance.
It's only if you DON;'T care about DX9 performance that the FX line even becomes an option.
Your conclusion is completley, 100% backwards.

I'd love nothing more than to strap a water cooling solution on this bad boy and watch it fly! Don't know if anyone's gonna let me tear stuff apart yet though ;-)Anonymous User - Wednesday, October 8, 2003 - link
Derek, Thanks for holding off on the buying adviceAnonymous User - Wednesday, October 8, 2003 - link
You should do another comparison that puts some extra cooling on the card, either by replacing the stock heatsink/fan or simply blowing more air across the card as if someone set a card cooler next to the video card. If the drivers worked well, this should noticeably improve card performance in a fairly inexpensive way.Anonymous User - Wednesday, October 8, 2003 - link
Good benchmark.. but you know, you've probably struck a nerve with all the ATi fanboys with that conclusion ;)And yes, I own a Radeon. Hate of fanboys is (or should be) universal.
