Beyond3D has the scoop on the ATI Radeon 9100 IGP integrated chipset. In terms
of integrated videochipsets, it seems pretty good, check out what they have
to say about it here.
As we can see the graphics for the RS300 chip has been cut back to two pixel
pipelines in order to keep its complexity, thus cost, as low as possible. However,
this allows the clock speeds to scale up to 300MHz, in turn regaining a small
amount of the performance deficit to the 9000/9200 discrete graphics chips.
The hardware Vertex Shader unit has also been removed to, again, keep the complexity
to a minimum.
