Did you calculate that number as (buswidth/8 * memclk)? 128/8*550 would be
8.8GB/s, but the base PCIe 6600 memory clock is 500MHz, and the memory is
*DDR*, so it is (buswidth/8 * memclk*2) = 16GB/s memory bandwidth. The AGP
version only has a memory clock of 450MHz, thus yielding 14.4GB/s.

You'll find those numbers on the official NVIDIA website here:

Isn't the 6800 the chip with the broken video engine in which exactly the
HDTV acceleration doesn't work? According to NVIDIA, the 6600 has the
bugfixed video engine, so I'd say the 6600 is the better choice if you want
both video acceleration as well as 3D gaming.
