Why ati radeon video cards doesn't have a Shader ?

and tell me it is ASUS ATI Radeon HD 4670 1GB GDDR3 better than NVIDIA GeForce 9600GT 512MB GDDR3 ?|||Yes ATI cards don't have a shader clock, But this doesn't make nvidia cards better, ATI Manages shaders in a different way. The two cards you have are around the same performance, However the ATI card is slightly better as it has increased memory (1GB) You wont really notice the difference though, unless your running a program that uses a lot of video memory.|||ATI cards don't have a shader clock because they have Stream Processors while Nvidia cards don't. It makes it so that it's a little bit harder to compare them but I believe that the ATI card is better, but if you want to game they both won't be able to do much, but if you just want to browse either will work fine!
