NVIDIA's GeForce 8800 (G80): GPUs Re-architected for DirectX 10

Prey Performance
With Prey being based off of the Doom 3 engine, only with some enhancements, scores tend to be quite a bit lower than many other games. At our maximum detail settings, dual graphics cards were previously required to play at the highest resolution. Now, a single 8800 GTX card is once again able to equal the performance of X1950 XTX CrossFire, which is no small achievement. The reduction in pixel and vertex processing power results in the 8800 GTS performing quite a bit lower, although it still manages to outperform 7950 GX2 by a small margin.
Quad SLI continues to be a disappointing prospect, providing no performance increase over a single GX2 card. The release of GeForce 8800 pretty much seals the fate of Quad SLI as well, as it's doubtful that NVIDIA will continue to invest time in optimizing the QSLI drivers when they have new GPUs that could make better use of optimizations. We can only hope that most of you didn't get sucked in by the marketing.

i'm sure there was a lot burried in there ... sorry if it wasn't easy to find.8800 gtx and gtx are both no louder than 7900 gtx. 1950 xtx still takes the cake for loudest graphics card around by a long shot -- especially after it heats up in a game.

E: More info would be nice

If you link VISTA -SANTA ROSA platform-Core2DUO(merom)CPU line up(T7300,7500,7700 models)then a matching Graphics card
to complete the link.
So a G80 for laptops/notebooks?
The pairing of Intels Santa Rosa platform with Vista in the 2Q 07 is next big thing for the first tier notebook manufacturers & all they need is a matching G80 for this setup.
Unquote-
Nvidia currently caters to Desktop requirement/needs with the new G80 releases,wonder how the notebook/server versions will be-with Vista ofcourse.

Vitual memory is probably a good thing for most cases, but in the graphics arena, this *could* potentially make for sloppy/ bad coding practises. Knowing a lot of game devers (some of which actually work for well known companies), I've heard them from time to time complain about maxing a 16x PCI-E pipe. What I'm trying to say here, is that while it would be a good thing for never having to run out of texture memory, but that system memory, and definately the swap disk can not hold a candle to the memory bandwidth that most Video cards are capable of. End result, is that you definately *will* get a performance hit. All this, and we already know the memory bandwidth capabilities of modern PCs, suffice it to say, the most we'll see from current systems is what ? 12-13K GB/s ? Even a 7800GS can do roughly 35 GB/s on card. A 7600GT ? 22GB/s ?Still I think Directx10 is a very good thing, and as I didnt read the whole article, perhaps a missed a little ? Reason being, I've been reading about Directx10 since April, and a friend of mine was privy to some of this information after an interview with ATI.

I don't know how they threading really works, but its quite possible VM support is required in order to allow multiple threads to run without stepping all over each other,.saratoga - Thursday, November 9, 2006 - link
Sorry, should read "I don't know how THEIR threading works"falc0ne - Thursday, November 9, 2006 - link
I don't know what is the problem but I'm really unable to see the images within the latest articles from Anand...Can anyone give me a suggestion? What might be the cause of that?The thing is I'm really, really interested in these articles and I need to see those images. Thanks

Oh, er, then in the options tab of Firefox, (tools->options->content) check the "load images" check box ;)falc0ne - Thursday, November 9, 2006 - link
well...it would've been simple but I'm afraid is not that...It might be the addblock extension from firefox, other than that I have nooo ideeea...Well I will use the IE tab option instead and load the pages using IE 7. Thanks anyway:)yyrkoon - Thursday, November 9, 2006 - link
Checked the exceptions list ? I know that firefox makes it really simple to block images from a site (to a point of being too easy).JarredWalton - Thursday, November 9, 2006 - link
If you've got AdBlock on Firefox, press Ctrl+Shift+A and you can see what it's blocking. If it blocks the images.anandtech.com stuff, you can then see which RegEx isn't working right and edit that.
