Although not apparent in the above diagram, the architectural efficiency of the
GeForce GTX 200 GPUs is substantially enhanced over the prior generation. We'll
be discussing many areas that were improved in more detail, such as texture
processing, geometry shading, dual issue, and stream out. In directed tests, GeForce
GTX 200 GPUs can attain efficiencies closer to the theoretical performance limits
than could prior generations.
Table 2 compares the GeForce 8800 GTX to the new GeForce GTX 280 GPU.
You will notice sizable increases in a number of important measurable parameters.
