7900 GT: Just Another 7800 GTX?
Rather than clutter up our performance tests with a full set of numbers from another card, we decided to sum up its performance first. As we saw in our card comparison charts, the 7900 GT has specifications nearly identical to the 7800 GTX. Here we take a look at the stock 7800 GTX vs. the stock 7900 GT. There are plenty of overclocked 7800 GTX cards around that will either perform exactly like or very slightly higher than the 7900 GT. But as our performance tests at 1920x1440 clearly show, the 7900 GT only marginally edges out the stock 7800 GTX in performance.
In the following performance tests, we included the 7800 GTX 512 in order to compare the performance improvement the 7900 GTX offers over the previous flagship. For a comparison between the original 7800 GTX and the 7900 GTX, simply imagine that the 7900 GT has a different label.

Or am I going to have to look for myself? Im too lazy Derek.DerekWilson - Thursday, March 9, 2006 - link
well... since the 7900 GT performs the same as the 7800 GTX ... and the 7800 GT performance relative to the 7800 GTX is well documented :-)You're right though, it might have been good to make this more clear.

So I suspect a 5-10% difference going from a 7800GT to a 7900GT.Phantronius - Thursday, March 9, 2006 - link
Derek, why are only the first graphs hightling the 7900' series in orange while the rest are totally blue? It makes it hard to compare them to the 7800 series.DerekWilson - Thursday, March 9, 2006 - link
sorry, we've had some problems with our graphign engine today -- I will make sure to update the colors on the rest of the graphs so they are more readable.my plan is to make the new single cards orange and their sli counterparts green.
I understand that it is a lot of data in one place, but I hope this helps.
Thanks,
Derek Wilson

I though sites reported that the die size of the R580 is supposed to be 313mm2 not 353mm2 as stated in the article???

Man, I've been reading this sight for like two years now and they always find a way to make me feel like a noob. Can anyone tell me what 'the IC' is? Didn't see the long form in the article.DerekWilson - Thursday, March 9, 2006 - link
Sorry ...Integrated Circuit.
It is the term for what is commonly refered to as a "chip"

Oh man that's embarassing...for some reason I just couldn't figure that. Sometimes the brain just doesn't work right.4AcesIII - Thursday, March 9, 2006 - link
Not an ATI fan anyways but it does seem that these boys favor ATI in almost every review. Now having had experience with ATI it makes me wonder how they can sleep at night knowing what sort of reputation, and consistant reputation ATI has for absolute crap software/drivers. Some of the TV cards they've put out aren't supported by themselves, left to 3rd party software and powervcr at that. Both ATI and Nvidia have good hardware the huge difference between them is implimentation via drivers and software. Nvidia can do it, ATI can't and they've proven it over time. Nvidia drivers are compatible with more of their older cards until you go back to 2mb TNT cards. ATI wasn't able to do this. I don't find Anandtech impartial anymore, they don't put out anywhere near the amount or quality of articles they used to and there's some plagerism claims about them floating around the web. Because of all this I only keep this link for amusement it's not considered a serious source of info anymore.
