New Nvidia uses its approach
ATI BELIEVES that you need many more pixel operations per clock than the pixel itself. Nvidia disagrees. It believes in a totally different ratio. With the birth of the R580, ATI believes that you should have three to one ratio as R580 has 48 Shaders and 16 pixel pipelines. You don’t need much mathematics to figure out that ATI preaches a three to one ratio.
As the G71 will be able to process 32 pixels per clock, it will physically have 32 pipelines but will have just 16 ROPs. This is no surprise to us as Nvidia's G70, Geforce 7800 GTX actually has 24 pipelines and 16 ROPs.
This means that Nvidia and ATI will take completely new approaches, where Nvidia will try to convince everyone that you need more raw pixels than pixel operations.
The G70, Geforce 7800 GTX has 24 texture memory units and 16 ROPs and can theoretically draw eight pixels with each, having three textures per clock. G71 will be able to do even more pixels per clock - it's as simple as that.
ATI's R580, on the other hand, will still be able to push sixteen raw pixels per clock but will be able to render 48 pixel operations per clock. So ATI will insist on more per pixels operations before you actually draw the pixel. This kind of makes sense when you need more maps and calculations per pixels.
I would fear the very successful and expensive "The way it's meant to be played" program which Nvidia spent some $160+ million dollars on last year. With that kind of budget it's much easier to convince developers and publishers that Nvidia's marchitecture is the best. We can surely say that 2006 will be just as full of marchitecture wars as 2005 was.
