NVIDIA prepping GeForce GTX 780 GHz Edition?

It seems the GeForce GTX 780 Ti will not be the only new card in NVIDIA's high-end lineup. While the GeForce GTX 780 Ti is expected to deliver a speedier alternative to TITAN, NVIDIA is also rumored to be working on a GeForce GTX 780 GHz Edition, a SKU based on the new GK110-300-B1 stepping.

This card will basically be an updated GeForce GTX 780 with a 1006MHz core, 1046MHz GPU boost and 6GHz memory. Add-in-board partners will be free to customize the cards as they please so you can expect to see lots of non-reference designs at launch.

Expreview discovered its Inno3D GTX 780 iChill HerculeZ 3000 graphics card to be based on this new silicon, and at its given speeds of 1006/1046/6008 MHz, found to to be about 15 percent faster than a standard GTX 780, and about 7 percent faster than a GTX TITAN. It's also about 6.2 percent faster than an R9 290X on the same test-bed. Power consumption isn't up significantly, and the cooler that's an Arctic Cooling solution, does a good job at keeping the temperatures manageable, and keeps throttle limits away.
