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

The Test
In our game tests, in every game we enabled the highest level of quality possible as far as features and effects are concerned. Where it was an option we enabled 16xAF in game. In games with "texture filtering" settings (like Battlefield 2) we endabled the highest level of filtering in game. In Oblivion we forced 16xAF in the control panel.
With the exception of Oblivion, we enabled AA in all our general performance tests. Where we were given the option, we chose 4xAA. In Black & White 2 and Company of Heroes we enabled AA in game (High for BW2 and Enabled for CoH).

A Few Words about Performance Per Watt
In the coming performance pages we will be looking at the performance of the 8800 series of graphics cards as well as power consumption and performance per watt of our test systems. Note that the power consumption and performance per watt we are reporting is for the entire system, and not just the GPU, so while you don't get an idea of the performance per watt of the GPU alone, you do get an idea of the performance per watt of the entire system configured as we have. This is an important distinction to keep in mind as performance per watt of the GPU alone could be very different than what we're reporting here. What these numbers will tell you however is the most power efficient setup we have configured here today.

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.
