The G72 core on show here shares the 90nm manufacturing process with NVIDIA's high-end G71 and mid-range G73 cores, and as you would expect is basically a heavily cut-down version of the G70 core with regards to its base architecture. Compared to the six pixel (or fragment) quads of the high-end parts, G72 only has a single quad (i.e. four pixel pipelines) to show for itself, and just two ROPs compared to the sixteen found in high performance G70 and G71 cores. G72 also suffers in the vertex shading department, losing five vertex shader units and thus retaining only three. The memory controller on board is also naturally cut-down, from 256-bit on G70 and G71 and 128-bit on G73 down to just a measly 64-bit interface on G72.
