Nvidia's G80 has 32 pixel pipes & 16 vertex & geometry Shaders

[Das Capitolin]

IT TURNS that the fancy Nvidia G80 chip taped out, and in working silicon stage it will have 32 pixel Shaders and, as predicted, have 16 vertex and geometry Shaders.
Nvidia wants to stick with a two to one ratio and assumes that the games of tomorrow will need twice as many pixels than they will need vertices and geometry information.

ATI believes in a different religion. ATI believes that every Shader should become one, united and bellowed. No more segregation to Pixel and Vertex Shaders. If ATI makes a chip with 64 Shader units all of them can do Shader either vertex or pixel or geometry stuff all the time. You can check the stories at the bottom for a better explanation.

We don’t know the clock speed of the upcoming performer but we don’t believe Nvidia can get more than 700MHz out of it - we could be wrong about that.

i got this same info from wikipedia yesterday lol, wikipedia is useful :-D beat ya' to it

SO why didn't you post it here? Keeping it to yourself is so selfish.

Oh, and I forgot... you aren't allowed to post in my threads. Go away.

[mousiness]

i posted it in members news isnt that where its supposed to be?

Damn I was hoping nVidia would step up the pixel pipes and vertex shaders more than 32 and 16 repsectively. They are gonna have to reply more on pure speed to compete with ATi.

afraid of more competition or are just just having you time of the month LOL

I would agree. There almost seems no point in a new GPU if it cannot exceed what the present line already accomplishes.

Mousiness: stay on topic, and you and I will be fine. You have gotten more of my topics closed then anyone else. You go OT more then anyone else I know. Next month will be that time of the month; when I travel to Ottawa.

[mousiness]

uh oh.... eeek i better watch out, you cant believe how hard it is for me to stay on topic, i will try my best to do it

[werty316]

uh oh.... eeek i better watch out, you cant believe how hard it is for me to stay on topic, i will try my best to do it

Good luck with that.

[mousiness]

thanks werty :wink:

Which is exactly why you should just stay out of my topic threads!

oh, and I can believe how hard it is for you to stay on topic... because you just went OT again.

[mousiness]

i stay out of our threads if you stay out of mine :wink:

i stay out of our threads if you stay out of mine :wink:

That's a deal. I have no problem with that at all; and I'm happy to see we can agree on something.

Yep, I think I'm definitely picking up a Bias in favor of ATI. They've incorperated more features and abilities into their GPUs than nVidia has, just one of which lets them get away with running HDR and AA+AF...

ATI’s next generation graphics card currently codenamed R600, will have unified shaders meaning that if the game is wanting to make use of pixel shaders all of the graphics cards onboard shaders can be used for that purpose if required meaning that there’s much better usage of the chip at any one time which will speed things up.

To make sure that the requests of the game / app are met between pixel , vertex and geometry shaders there are a number of arbiter units on the R600 allowing the chip to load balance what its doing at any one time to maximize the workload.

If done correctly this should be a huge advantage over the non-flexible fixed architecture of the G80 series... which is probably why nVidia already announced long ago they planned to follow ATI's lead in unified shaders in their next design after G80... ;)

Honestly though, ATI's use of US's is probably the biggest news in a long time for video cards. Now if they could get the Physics logic incorporated they would totally put it to nVidia.

I also consider ATi a bit ontop of nVidia based on the hardware side but not with dual GPUS as SLi has been in the game longer and I think is better developed; equal on the driver side since both nVidia and ATi both use a ridiculous control panel.

I agree that SLI beats Crossfire, but when it comes to drivers ATI wins*.

ATI has four different components of its driver package. I only ever use the driver, not the control panels or other software. nVidia's drivers install it all as a single itegrated package. Even if you use the Locate Driver function on a extracted driver package, it still install the other software.

This is true, but nVidia did have a good lead time before ATI tried to follow... ATI was catching up.

Regardless though, the mainstream user does not use SLI or Crossfire. That's above my abilities as well, and even if it wasn't I still don't see a point to paying twice the cash for at aboslute best case scenario of 1/2 to 2/3 again the frame rates. Usually you're lucky to get even half, I think. This doesn't even include paying a good bit more for a SLI or Crossfire motherboard either.

I have built SLI and CrossFire systems, and was not impressed; especially for the cost. Make sure to vote in the poll here:

ATi came along way from its first Xpress 200 chipest and they have done a good job with the Xpress 3200 and 1600 xFire chips.

I cant remember where I read about the ati chipset development, but the reviewers mentioned that ati was 1 generation away from competing or beating nvidia on the chipset/mobo level too.

So it seems that ati, in the next generation of its video card and motherboard, may leapfrog nvidia on both fronts. I hope that occurs because whether you buy nvidia or ati, prices are sure to come down.
