NVIDIA Launches the GeForce GTX 780 at $649
The GeForce GTX 780 doesn’t introduce any new technology or a new GPU chipset, as it is a part of the Kepler family. The GTX 780 also uses the same GK110 GPU that was introduced a few months earlier with the GeForce Titan, but it has been slightly gimped, with lesser amount of steam processors and texture units. As a result, the GTX 780 is slower than the Titan, but not by much.
Benchmarks of the GeForce GTX 780 can be found at several hardware sites:
