AT Exclusive Preview: The GeForce 7800 GS Hits the Scene

Introduction
A little over a week ago we received an email from someone claiming to have a GeForce 7800GS. After checking out the card and the emails from NVIDIA confirming that this was in fact a GeForce 7800GS, we knew we had something special on our hands. Today we bring you an engineering prototype that only exists inside NVIDIA, but roadmaps and driver sets indicate this card is the eventual GeForce 6800GT replacement.
We have heard that this part was in the works over at NVIDIA, but we haven't yet heard when this product will be making its way out into the world. Apparently there are board floating around, and since we were lucky enough to get our hands on one we decided to put it through some performance tests and see what it could do. From what we have seen on roadmaps, the performance of the 7800 GS should fall between that of the 6800 GS and the 7800 GT.
Not knowing when this part will actually arrive, or how close to final this part is, means that we could see some small revisions in the card between now and release. Clock speed could change a little bit, but we don't see pipeline configuration changing. If total performance is anything like this in the retail product, we will be quite interested in this part when it is released to the public.

Sorry if this was already mentioned in the article, but is there a reason that there were no pictures of the actual card? Were there distinguishing marks/logos on the card that would have revealed to Nvidia which company had leaked the card, or was it just due to legal issues?gulizi - Saturday, November 26, 2005 - link

This 7800GT http://www.newegg.com/Product/Product.asp?Item=N82...">http://www.newegg.com/Product/Product.asp?Item=N82... is ($289.00, after $50.00 MIR).

thankfully the 12x10 4x 8x are on there. anyone know the availbility date since this was a sneak peak?yacoub - Wednesday, November 23, 2005 - link
The only thing you didn't mention in your conclusion are the prices of the ATI cards, which would really help drive the point home that the 7800 GS or GT are the way to go.LoneWolf15 - Wednesday, November 23, 2005 - link
That Anandtech has posted that cards in a test (I saw this last week too, but didn't mention it then) include the Radeon X800XL, and then didn't. I'm getting really tired of it. It seems like a simple thing, but a lot of people purchased the X800XL as a performance/value solution, and the comparison is worth it to us. I'd like to see Anandtech tes with it, but if you decide not to, REMOVE IT FROM THE LIST OF CARDS IN YOUR TESTING SO THAT NO-ONE IS LED ON. Don't you guys have ANY PROOFREADERS?(pauses, takes several deep breaths) Rant over. Carry on.
P.S. It appears that in looking closer, your tests include the X1800XL, which is not listed in the test specs. Perhaps the specs have a typo, but if so, it's rather an egregious one...maybe you could correct it?

I'll second the notion that the X800XL would be nice to include since that was the hottest bang-for-the-buck card just a couple months ago.DerekWilson - Wednesday, November 23, 2005 - link
Would you guys rather see an X800 GTO or an X800 XL in future reviews of this nature?Also, it was a typo. It should have read X1800XL. I'm sorry about the confusion.
As always, we very much appreciate our readers pointing out errors we need to correct. Thanks!

There seems to be something wrong with the x1800 parts in the Black and White 2 Benchmarks, since they perform quite a bit below the x850 xt, even though they are faster in every way.Is it really proper to include scores that seem to be bugged?

If a hardware/software combination has a problem isn't it even more important that we report it? This is an accurate measure of the performance of the different parts with equivalent settings. We checked and rechecked our benchmarks this time and there's no doubt that R4xx hardware runs B&W2 better thant R5xx hardware with the latest ATI drivers.This is a problem and we hope ATI or Lionhead will take notice and fix the issue.
