Does the 9800 GX2 have two GPU's on one card?

I guess the name GX2 should be a give away but I wanted to clairify if the 9800GX2 contains one or two GPU's. If it's dual GPU how would one 9800GX2 compaire to two 8800GTX's in SLI?

Another note are there driver problems with the 9800 right now?
 
Are they G92 cores? Additionally would you need a PCI-Express 2.0 to take full advantage of the card? I know they are backwards compatible with 1.0 but does having a 2.0 board make a significant difference?
 
Yes, G92. In terms of performance, it should is all i can say, and it will improve as drivers improve. Essentially it should double the throughput of the PCIe bus. Just be careful about the compatiability though, although PCIe 2.0 cards are compatiable with PCIe 1.1, they are not always compatiable with PCIe 1.0a. Just check that.
 
They are two PCB's, it's different from the 3800 X2 which has two cores on a single PCB.
 
indeed. btw Omega, just looked at your stuff for sale, you must be spewing that you bought a 2900???
 
Its slower than the old GTS, was more expensive and chugged power like all hell due to its 80nm architecture.

The 2900XT is better then the older 8800GTS. The 2900XT overclocks like a beast and outperforms over the 8800GT if you can control the heat.
 
Reference? Because everything i look at on the VGA 2007 Charts on my sig, disagree.

And here:http://www.custompc.co.uk/labs/120833/ati_radeon_hd_2900xt.html

"...by focusing on shader processing, including shader-based AA, the HD 2900XT takes a huge performance hit when using multisampling AA, and its filtering performance also lags behind that of the 640MB 8800 GTS. In many ways, this masks the true power of the GPU and can mean that it performs worse than a 640MB 8800 GTS in certain games. In addition, the HD 2900XT consumes more power than the 640MB 8800 GTS, runs hotter and is far noisier."

btw we have hijacked this thread, shall we start a new one?

You can't trust Tom's Hardware VGA charts, as they tend to use different hardware for different systems.

http://www.dailytech.com/article.aspx?newsid=7043 (Take a look at the scores/FPS on the bottom of the page)

I'm not saying it's a night and day difference, but when it was released it was the same price as the 8800GTS, so it wasn't overpriced for it's time.
 
You trust that? You think a 8800GTS gets less than 60fps in call of duty 2? Less than company of heroes?? lol, that is not a strong link omega... none the less i think that wasn't ATi's best card..
 
Sorry those number don't add up, and even if they did, it doesn't redeem the 2900xt imho.

The 320mb version of the 8800GTS gets around 90fps in Fear at a higher resolution 1680 x 1050??? here: http://www.custompc.co.uk/images/slideshow/66757

compared to your link:

where the 640mb version at a lower resolution 1280 x 1024 gets only 83fps???

those number in your link are dodgy omega and the 2900XT was a doozy and it brings into doubt your claim about the 2900 being faster than the 8800GTS, particularly when i have previously provided two reputable links that show the opposite. COD2 should be getting over 100 fps and is far from a taxing game graphically. A 6200 AGP card can play it fine.

Don't forget, these tests were run over a year ago before the newer patches and drivers were released, which is what really hindered the 2900XT. In all the benchmarks here they had to use BETA drivers, however benchmarks later on showed quite a drastic increase in FPS with the newer stable drivers.

I've had both the 8800GTS 640MB and the 2900XT 512MB, with similar setups (E6300 and 2GB with the GTS, and E6400 and 2GB with the XT). And I can say that the 2900XT performed much better in games, I also got several thousand points more in 3DMark06. I was lucky to break 10K with the GTS, however I easily got 14K with the XT.

The point is, when the 2900XT was released well over a year ago, it was priced very closely to that of the 8800GTS 640MB, and performs slightly better.

This is besides the point of the thread anyways. Why did you even bring this up?

The thread has been answered, plus as you can see, i did mention this a while ago...

I dont agree with your analysis, also, the drivers are not that disimliar to the newer ones (both 8.3).
