Benchmarks and Overclocking
I ran 3dMark06, 3dMark05 and 3dMark03 and 3dMark01 to get a flavour of how the card performs in these benchmarks. These benchmarks are all from Futuremark and test a variety of 3d effects, from DirectX7 and upwards to 3dMark06 that is a real test on a lot of DirectX 9.0c features.
7800GTX 512mb (630/1830)
These benchmarks came out very strange, some with the X1900XT-X winning over the 7800GTX, some not so. Remember that the 7800GTX is clocked at as high as it would go on air, whereas the X1900XT-X is simply an OC that is being held back by the drivers. Also I believe that the ATI drivers really need some optimising to get up there with the 7800GTX, and I will certainly push the card much further than this.
I have only done what I consider as a mild overclock on this card using the "ATI Overdrive" feature in the ATI drivers.
The max that you can get to in that is 690 Core and 800 Memory. I pressed the "run automated clock configuration utility" and this went straight up to the maximum.
I ran all of the tests at this setting as I considered that this overclock is only a mild OC and the card has a far higher headroom than this, especially with the 900Mhz rated Samsung Memory. The card is not even struggling at this speed and I will certainly be getting it higher!
Notes on ATI's control Centre
ATI's control centre is very good for the options that I wanted to enable on this card such as Temporal Anti-aliasing, Anisotropic Filtering and Adaptive Aliasing.
Overclocking does not fair quite as well compared to nvidia's "Coolbits" reg hack. The ATI drivers only allowed up to 690/800 for this card, which was very blatently far lower than the card could achieve.
Here is where nvidia\'s excellent well thought out drivers fair much better in my opinion, but I\'m off to hunt myself a tool that will do it for me better (RivaTuner) so its really a minor point.
The drivers with the card did do some very strange things at times at times, but I have at points found that the nvidia drivers did the same thing, especially at the release of the 7800GTX 512mb.
