VR-Zone came to know that the future is actually pretty near where NVIDIA G80 design is based on unified shader architecture slated to appear in 2006. ATI has already taken the unified approach for their R500 Xenon within the XBox 360 and has 48 unified pipelines.As we know, in an unified shader architecture, there are no dedicated vertex and pixel shader engines but unified shader engine capable of executing both types of instructions.
