At the same time, the GeForce 7800 GTX 512MB's price will drop to $399.
Nvidia’s code-named G71 graphics processing unit (GPU) will be a 90nm version of the original code-named G70 GPU that has 24 pixel processors and 8 vertex processors. The G70 was originally made using 110nm process technology, which means that producing it using the thinner 90nm fabrication process will decrease the cost of manufacturing and will allow higher clock-speeds compared to existing maximum of 550MHz.More info at X-bit Labs.
The GeForce 7900 GTX product will have clock-speeds of 650MHz for the chip and 1600MHz memory, some informed sources have indicated. The new GeForce 7900 GT product will have 450MHz/1300MHz clock-speeds for core/memory.
