The 1 GHz barrier for GPU clock speed has been under interest for some time but just a few cards manage to make it that far. The GeForce GTX 780 GHz Edition promises to do exactly that with not much effort.
Indeed NVIDIA has started work on such a graphics adapter. The upcoming NVIDIA product will be based on the GK110-300 rev. B1 GPU that supports higher clock speeds. Thus this card will run at 1006 MHz for the GPU, a frequency that will reach 1046 MHz when the card enters Turbo mode. As a comparison the regular GTX 780 works at 863 MHz and 900 MHz in Turbo Mode. The rest of the specs of the GeForce GTX 780 GHz Edition are in full accordance with the specs of the GTX 780.
The official release date has not been disclosed. As to the new card it is expected to retail for USD 599.
