Johanson said:This is getting stupid. Nvidia wants you to have 4 GPUs and ATI wants you to have 3 GPUs. Then there's PhysX who want you to have a PPU.
I hope all this comes in one nice package in a couple of years!
Well they'll be holding tech back until DX10 comes out - what's the point of designing a new GPU architecture just to have to redesign in 6 months time?Kabaala said:This whole thing with Nvidia and Ati is beginning to stink of hitting a brick wall with being able to create NEW technology rather than speedbumping and combining of existing.

Gerard said:Take it you never read the article, the purpose of the third gpu is for physics.
Johanson said:I know. They still want you to have 3 of their graphics cards though. I was trying to say that the whole GPU and PPU situation is becoming too complicated and expensive.
LoadsaMoney said:I cant see how they want you to have 3x GPU's, as it says you can have an x1900 XTX doing the graphics, and you can pair it with an x1600 or something, and the x1600 will only do the physics, thats 2x cards still.
Tommy B said:Why not just make ONE awesomely powerful GPU.
LoadsaMoney said:Nah you wouldnt need 3x cards, quoted from the Article.
According to ATI’s internal benchmarks, Ageia PhysX PPU (366MHz) can perform about half a million sphere-to-sphere collisions per second, whereas the Radeon X1600 XT (590MHz, 12 pixel shader processors) delivers over a million, meanwhile performance of Radeon X1900 XTX (650MHz, 48 pixel shader processors) reaches five million sphere-to-sphere collisions per second.
x1900 XTX absolutely obliterates the Ageia, and even the x1600 beats it to, surely one x1900 XTX doing that many collisions would be enough, so 2x x1900's in Crossfire would do if one card was doing the physics i rekon.
It is getting a bit stupid now though.
"Of course, the first games to use Havok FX aren't expected until later this year. Havok FX isn't exactly comparable to what Ageia's doing with hardware physics acceleration, either; Havok FX is limited to "effects physics" that don't affect gameplay, while Ageia's PhysX PPU has no such limitation". - http://techreport.com/onearticle.x/10117
