NVIDIA GeForce Go 6800 vs NVIDIA GeForce Go 6400 vs NVIDIA GeForce Go 6250
NVIDIA GeForce Go 6800► remove
NVIDIA GeForce Go 6800 is lower clocked than the 6800 Ultra video card for notebooks (and also cooler). The number of pixel pipelines and vertex pipelines is the same like in 6800 Ultra.
Currently the performance of the 6800 is only compareable to a 8600M GT middle class graphics card.
The PureVideo technology delivers acceleration for H.264, WMV, and MPEG2 videos (also in HD) but has a bit less features than the PureVideo engine in the 8600M GT. > Comparison

The NVIDIA GeForce Go 6400 is inserted in favorable notebooks and technically a higher clocked GeForce Go 6200. It has been replaced by Go 7400. Beside the integrated memory of 32 MB the card can reserve up to 128 MB of the main memory (TurboCache).
Due to few integrated memory and only 64 memory bus, the highest gaming performance can not be expected from GeForce Go 6400.
The PureVideo functions enable the 6400 to accelerate the playback of MPEG videos (not in HD). > Comparison Table

The NVIDIA GeForce Go 6250 is a low end laptop graphics card of the GeForce Go 6000 series. It is based on the 6200 and 6400 chip and offers a small amount of dedicated DDR graphics memory. Usually it is adverted with additional shared memory called TurboCache.
An advantage are the integrated PureVideo functions for decoding MPEG videos with the GPU (but not HD videos).
The performance of the 6250 is too weak for gamers. The power consumption should be relatively low, but not as low as integrated graphics cards offer.
