Nvidia's G70 GPU Core

Before we can even examine Gigabyte's 7800 GTX, we must first examine the G70 core and its key differences and improvements, making it THE card to have in an industry full of speed freaks and gaming gurus.  While still based on the same architecture as the 6800 Ultra series, the 7800 GTX has a significant number of improvements that make the G70 core the most robust graphical core to date. 

Based on TSMC's 110nm process, the G70 core boasts a total of 302 million transistors in comparison to the NV40's 222 million transistors.  People were already stunned by the amount of transistor counts on the original 6800 Ultra and X800 XT, in comparison to high-end CPUs, such as the FX-57 that supports about 114 million transistors and now the G70 core supports three times as much transistors as the FX-57.  Nvidia also added 8 pixel pipelines for a total of 24 total pipelines on the G70 and also added 2 extra vertex shaders for a total of 8, in comparison to the older 6800 Ultra's total of 6.  The fill rate has also been increased for a maximum of 10.32 Gigatexels in comparison to the 6800 Ultra's 6.4 Gigatexels.
