Hi guys,
I don't know much but there is a rumor outhere ATI R600 would come with 64 physical pipes that can run either vertex or pixel shaders. While this is perfect for games, I'm wondering if this would help CAD programs.
My reasoning is like this...CAD programs are vertex calculation intensive as opposed to games that have a balance between vertex/pixel calculations. Curently, for profesional cards like Quadro and FireGL series it seems that the faster the GPU core and the more vertex pipes the card has the better the card performance. Currently the cards have something like 8 vertex pipes, but imagine what would happen once it can use 64 at once. Am I missing something? Can some of more knowledgeable guys comment about OpenGL apps performance on ATI R600?
Also...Because of VISTA only DirectX10 policy it seems that ATI R600 features would work only on Vista. Knowing that Vista has a OpenGL->DirectX API mapping, how would that affect OpenGL performance? What about OpenGL games like Quake4 on Vista? Will NVIDIA and AMDATI offer native OpenGL drivers on Vista for consumer cards? Or only for professional ones? What about WinXP and ATI R600 combination?
Well...I have well too many questions, but my main problem is it worth upgrading my CAD workstation to Vista to get more performance/video cards options (currently have AMD X2 4600, ATI X850 Pro, 4GB ram) ?
Peace,
Lav
