ATI's graphics chip was implemented using the Cadence X Architecture design solution and fabricated in TSMC's 0.11-micron process. This X Architecture implementation eliminated one metal layer from the original Manhattan design, reducing die costs.

Does anyone know what this chip is? I would suspect it is a motherboard chipset with intergrated graphics.
