7900GTX vs. X1900XTX (PixelPipes???)

Over the past month (or two) I have been indecisive(sp) on wether to choose a nVidia 7900GTX or a ATi Radeon X1900XTX. When looking at the fps, they match up (almost) evenly, but if I look at the specs. on the cards, the one main difference I see is the PixelPipelines. I read the VC101, but I still don't totally understand this. Well I'll show the difference:

eVGA Geforce 7900GTX 512MB - PixelPipelines: 24

SAPPHIRE Radeon X1900XTX 512MB - PixelPipelines: 16 (48 Pixel Shader Procs.)

Even thought the clocks differ a little bit, the pipelines are the only thing that seem to seprate the two. Does this mean that (out of the two) ATi has the superior card? Because in (most) of the benchmarks I've seen, the 7900GTX has more fps.... I'M CONFUSED!! Please help me make up my mind! :eek:

(oh, and BTW, I'm not out to get a few extra fps, just would like to know which is better and to have a clear definition on whats the difference between "Pixel Pipelines" and "Pixel Shader Processors." Thx!)
 
Yeah I agree, go with the X1900XTX / X1950XT/X if you can afford it! :)

It will enable you to also use HRD whilst AA is enabled.

Also you get the a bit of a cheaper deal (Depending on where you look and what card's you look at (before I get flamed:rolleyes: )
 
Hey, I guess expirence beats explanations, even though I've (mostly) been an nVidia man, but hey, it's not to bad to mix it up every once in a while...

Oh, and QUICK question, I haven't seen any comparisons between the 7950gt, gtx, and x1900XTX EDIT 3: and the 7900GTO. I know the the 7950gt/7900GTO is new, but does it preform better/worse than the other two?

EDIT: Because the 7950GT/7900GTO is alot cheaper than the two...

(Oh, and for sake of opinion, When either of the companies release their DX10 cards, who do you guyz think will startoff/win the race? lol....)

EDIT 2: I've also read that ATi tend to have self rendering issues with shadows (in Oblivion for example). Is this true and if so have they fixed it?

EDIT#3: the 7900GTO is a downclocked 7900GTX, the 7950GT is a single card version of the 7950GX2, the best of the cards are as followed:
X1950XTX 768MB i think?
X1900XTX 512MB
7950GX2 1GB
7900GTX 512MB
X1900XT 256MB
7900GTO 512MB
7950GT
7900GT


EDIT#1: cheaper, thats why i went with a 7900GTO rather then a X1900XT
EDIT#2: i think there are patches...
 
I dont know why everyone keeps bringing up enabling AA and HDR at the same time such a big plus... you cant really make out a difference weither AA is enabled or not whils having HDR enabled.

That's not with HDR though. IMO, HDR is the biggest crock, I find it makes objects in the distance blury and the immediate light look fake. Not that non HDR lighting looks overly real.
 
Ya AA actually makes a big difference in how a game looks, but you don't notice as big of a difference between like 4x and 8x. Anyway a higher resolution also minimizes how pixelated the picture seems, but ya aa rocks, its just tough on your gpu.

Nice screenies omega, you can really tell the difference even at that size :D
 
Nvidia card can run AA + HDR in some games like HL2.

NO, No you wrong, 7950GX2 is faster than both X1950XTX and X1900XTX.
Also X1950XTX has 512MB memory, not 768MB.

HL2, 1600x1200
Hard Truck Apocalypse 1600x1200
Oblivion Elder Scrolls

By here I am laughing uncontrollably at the 7950GX2 :) Just to be complete:

Prey
Rise of Nations, rise of legends
Titan Quest
3dmark06 (WOW! the 7950GX2 for it's first win :) )
Ah!! it wins again! Wonderful unrealistic syntetic benchmarks :)

A much better comparison is the 7900GTX vs. the X1950XTX. The X1950XTX wins in all game tests except Titan Quest, and each win on one 3dmark06 test. However, each result is much closer than with the above series.

Final result:
1950XTX=6
7900GTX=2

Look at the benchmarks at this site ^ and you will see that 7950 GX2 is faster than the Radeon X1950 XTX in the majority of games. Also don't forget to read the conclusion.


Edit: Also, look at this site http://xtreview.com/review141.htm , 7950GX2 beats X1950XTX in most of the games

I guess now you get to the choice: Do I trust Tomshardware or Xbitlabs more?

It all comes down to if you like Nvidia or Ati more. And, if want HDR and AA on at the same time.

Well the 7950GX2 is pretty much the top dog in terms of raw performance, after all it has dual GPU's so I wouldnt expect much else. :rolleyes:

But theres alot more to a card than that, especially at this level. :)

I looked at these benchmarks and it looks to me that it is fake, and I think that any person will know that these benchmark is fake when he see them.(except if this person was stuped)

How can a 7950GT and 7900GTX beat 7950GX2 in all benchmarks in the website you posted?

7950GX2 has two GPU's and it is much faster than 7900GTX. It supposed to beat 7900GTX by far
 
I'd trust xbit over tomshardware, but that's just me :P

However I did just hear down the pipeline that games on the HL2 engine can do FSAA+HDR but I don't think the HDR is done by hardware in HL2 (it's either that or the FSAA is soft enabled).

The method of HDR in HL2 is different than Oblivion and FarCry.
The source engine in HL2 uses integer HDR, while in oblivion and farcry it uses FP16 HDR, and nvidia can't do FP16 HDR + AA at the same time.

Also, nvidia card will be able to run in HDR + AA Dark Messiah: Might & Magic because it uses the same method as HL2

X1900xtx

Faster isn't always better in video cards just like cpu's we all know this. I have the x1900xtx and it delivers superb eye candy without barely breaking a sweat. I have 60fps in almost every game I run nearly constantly, it would probably be higher but there is a little thing called V. Sync, which is fine. 60 fps is more than enough and the games I play are utterly awe inspiring, I couldn't do anything but recommend this card.

Regardless of FPS this card delivers, bottom line.

AFAIK it's the same method Crytek is using in FarCry (which can do it with a patch), which is a software fix. Using the shaders to do HDR is slower then the hardware approach. Also, if you want to through FP terms around: In 'FP32 mode' on an NVidia card an ALU is taken for AA and the rest are used for shader operations, in otherwords it is missing one. To get both you use FP16 or the shaders to pretend to do HDR.
