NVIDIA GeForce Go 6800 Ultra vs NVIDIA GeForce Go 6400 vs NVIDIA GeForce Go 6250
NVIDIA GeForce Go 6800 Ultra► remove
The mobile top video card of the 6000 series brought more desktop-comparable performance in notebooks. Nevertheless, it also has a considerable current consumption and heat development.
It is a higher clocked Geforce Go 6800 (not more pipelines!) and therefore faster and hotter, too. It was replaced by 7800 GTX and 7900 GTX.
NVIDIA GeForce Go 6400► remove
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 It has been replaced by Go 7400.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
NVIDIA GeForce Go 6250► remove
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.
