How much of a difference do they make? If Nvidia's cards don't have them does it make a big difference. Maybe someone could explain them a little better for me because its rather confusing :confused: :confused:
 
Ok I gues what I mean is if ATI cards have these 48 or so unified shaders and Nvidia Cards have none then does that mean that ATI cards are ahead of nvidia cards? What does this mean performance wise. Sorry if I make no sense.
 
No ATI doesn't have unified shaders as of yet on there PC gpu's but they do have it in the xbox . and I would say ATI is farther abead than NV in unified arch. There is also the fact that ATI and Microsoft are working very closely together . We all know that R600(r620) is unified. Many people including myself don't believe for a second that G80 will be a unified tech.

So just a guess I would say R600(R620) >G80
 
It is yet to be seen though how a unified shader arch compares to a non unified shader arch, technically speaking for games.

I'm not 100% sure but I don't think it is required for the actual hardware to have unified shader processors for DX10.

It's still way to early to garner anything concrete with all of this, those that know DX10 requirements and specs are keeping tight lipped right now, give it time, the facts will make themselves known.
 
okay I was a little mixed up. I'm glad I got some insight on the unfide shaders, but what I was talking about in terms of current gpus is the shader processors that are in the x1900 series of cards. How much of a difference do they make? Or do the extra 8 pipelines on the nvidia cards make up for that? Thats whats really confusing me. The reason I am wanting to know is because I am getting ready to upgrade from my 7800 gtx 256mb. I decided that I would wait untill the 7900gtx is out to see how it fairs against the x1900xtx. I was dead set on getting the xtx but because my friends were talking about how great the shader processors are in newer games. Then I realized I don't even know that much about what they do. All I know basicly is that the x1900 has 16 pipes and these 48 "shader processors". Where as the 7900 gtx (supposedly) has 24 pipes but none of these shader processors. Sorry for rambling I just thought I'd say exactly what I DO know so you all can explain things a little clearer. :)
 
The G70 (GeForce 7800 GT/GTX) has 48 ALU's (shader processors) in the pixel shader pipelines, just like the X1900 XT/XTX.

We all know that rumours have indicated as such. That's really all we know.
