power vr tbdr vs. z-buffer

[Anarchist420]

What are the advantages and disadvantages of each?

Is depth precision distributed evenly with Power VR's tile based rendering?

I still have somewhere a kyro II graphics card. It worked great and was a lot faster then the other graphics cards based on brute force in the pre T&L era.
After T&L was becoming more prevalent, the PowerVR became to expensive when compared because it needed a seperate DSP without redesigning the powervr principle.

I was loving the Dreamcast though. It looked every but as good as the PCs of its era albeit at a lower resolution.
