Pictures of the NVIDIA GeForce 8800GTS and 8800GTX show what looks like two graphics processors. However, the smaller second chip is dedicated to "NV I/O".

It turns out that the small chip on the Geforce 8800 cards is an Nvidia NVIO chip. It provides dual 400MHz RAMDAC and Dual - Dual Link DVI output, TV Out and HDCP. Our informative friends call the chip External Video I/O Chip or simply External RAMDAC. We don't have any idea why Nvidia needed that, as RAMDAC has been normally part of the chip for generations.

There are also specifications showing the power requirements for the NVIDIA GeForce 8800GTS and GTX. The 8800GTS will require 26 amps on the 12 volt rail, and the 8800GTX will require a whopping 30 amps on the 12 volt rail. The 8800GTX also has a second SLI bridge, which may link to a future physics solution from NVIDIA.
