The Kyro II follows on in the line of PowerVR cards that do the rendering in a completely different way; to put it simply the Kyro chipset only renders what is visible in a 3D scene. When an object is in front of another it blocks the object behind it, with a traditional render device such as a GeForce, it renders everything in the scene and then just before the scene is displayed the hidden objects are hidden, the Kyro, only renders what is visible, thereby saving a whole lot of memory bandwidth on hidden objects, the hidden objects are taken out of the equation long before a rendering call is given. The picture below shows the differences between the two different rendering platforms.
