NVIDIA GeForce 7800 GTX 512: More Than Just More Memory

Black & White 2 Performance
Black & White 2 is one of the most graphically taxing games to come out lately. This game is just as much fun as its predecessor and looks amazing to boot. This game features many cutting edge graphical effects like depth of field and HDR. Because of the aggressive nature with which Lionhead attacked graphics in Black & White 2, MSAA (Multisample Antialiasing) couldn't be employed. But due to the vibrant and high contrast nature of the game, FSAA can have a big impact on visual quality. In order to make up for the lack of MSAA support, Lionhead implemented SSAA (Supersample Antialiasing) in their game. While SSAA can trash performance on low-end to midrange hardware (even at modest resolutions), high performance cards can generally handle it.
Playability with Black & White 2 extends down to around 20 fps. The fast paced responsiveness required by an FPS is not really needed here, but dropping below 20 fps can cramp your style when you're trying to hurl boulders or fireballs at enemy troops. It is clear the SLI has a good impact on performance, and the 7800 GTX 512 maintains incredible framerates (for B&W2 with all the settings at their highest level).

I guess if you buy this card you´re doing so partly because you´re interested in running games in the hiqhest quality settings. But afaik it can´t do OpenEXR HDR and AA like in Far Cry, so I think this card is somewhat of a contradiction. Surely it depends on how the appliction uses HDR, like Valve showed with HDR and AA for everyone in Lost Coast. But I would say, not a very futureproof card then, as everyone predicts HDR will be big in games, and I guess a lot of them will use OpenEXR. Still, it will top the charts, for what that´s worth.And about the extra memory, how about taking the card for a spin with Call of Duty 2? Seems that game takes advantage of 512 MiB.

The advantage ATI offers is MSAA with floating point HDR. We've already seen a game (Black and White 2) that employs AA and HDR by using Supersample FSAA, and as you pointed out Valves Source engine avoids full float render targets and still gets good results.The performance hit is larger with SSAA, but it is certainly possible to have HDR and AA without the ability to do MSAA on floating point/multiple render targets. And the sheer brute strenth the 7800 GTX 512 has can easily be spent on SSAA as shown (again) by Black and White 2.

i'm an ati fan but this is ridicoulous. ati just gets crushed and crushed. even the regular 7800 gtx gets crushed. but i knew something like this would happen if the 7800 was cranked up to a clockspeed close to the x1800xt. those extra 8 pipes and the extra memory bandwidth just lead to the same thing: crushing all opponents lol. man. is ati the new intel? i hope not :(. but thats how its looking currently :'(.ha ha i guess my x800xt aiw isn't looking so hot right now :-D.

But quite useless for most people who don't run games at statospheric resolutions.I would really like to see this running at 2560x1600 on the Apple 30".

That is some pretty amazing performance. It makes my ATi X800Xl look rather pathetic...sighsKaPolski - Monday, November 14, 2005 - link
GoGo geforce 3 ti500 Woohoo!!!!! trust me it spanks the 7800 gtx 512 down to a carefully squeezed lemon :DXenoterranos - Monday, November 14, 2005 - link
w00t! I traded my matching-numbers first-run GeForce 3 (Before they were TI'd) in for a 5900. im not upgrading till socket M2 comes a-rolling into the bargain bin.LoneWolf15 - Monday, November 14, 2005 - link
It's called "marketing". Don't succumb to it.It it a fast card? Heck yeah. Is it necessary? Far from it. I have an ATI X800XL as well, and I don't plan on switching until I have to. Game developers will continue to make games compatible with our cards for some time to come, and the only thing we'll be missing is Shader Model 3.0. So far, what I have seen of it hasn't been a big enough improvement to encourage me to go out and plunk cash down on a new card. And seeing as my gaming is now measured in hours per week (as opposed to hours per day, like when I worked in a computer store) I couldn't justify spending that kind of bread on something that isn't constantly in use.
I think the 7800GTX 512 is a neat looking toy. But that's just it: it's a toy. I'd rather cover two car payments or two-thirds of a mortgage payment, things I NEED to spend money on

I agree. I also think the $600 dollar pricetag on the x1800xt is a bit much as well.

LOL. Weary != wary and in fact reads as the opposite to what I think you mean in this sentence!
