GeForce 7800 GT: GeForce 7800 GTX’s Younger Brother
Both, GeForce 7800 GTX and GeForce 7800 GT are based on G70 GPU manufactured by TSMC with 0.11micron technology. The NVIDIA GeForce 7800 GT graphics processor differs from its elder brother by fewer functional units and lower working frequency. As for the functional features of the product family leader, the more affordable version of it has it all onboard.
The major difference between the GT and GTX models is the 20 pixel processors (instead of 24) and 7 vertex processors (instead of 8). NVIDIA claims that the newcomer works at 400MHz core clock speed, compared with 430MHz of the GTX modification.
So, we can clearly see that even a “lite” version of the new GeForce 7800 GTX solution boasts better specifications than the GeForce 6800 Ultra. Of course, it implies also higher performance in games and other applications.
