NVIDIA's AIB partner Galaxy leaked a product sheet of GeForce GTX 780 Ti graphics card. According to that leaked spec sheet, GTX 780 Ti comes with fully unlocked GK110 graphics processing unit.
15 SMX clusters of fully unlocked Kepler GK110 make up a total of 2880 CUDA cores and 240 TMUs. GPU runs at 876 MHz base clock and 928 MHz boost clock. 3GB of GDDR5 memory connected to GPU via 384-bit bus received a massive clock bump and now runs at 7008 MHz as opposed to 6008 MHz on all other GK110 GPU-based graphics cards. As a result, memory bandwidth increased from 288 GB/s to 336 GB/s. The card's price remains the same at $699.
VideoCardz also report that GTX 780 Ti will come in special Black Edition featuring GPU base clock of 1 GHz and boost clock of 1033 MHz. These special edition cards could come in variants with 6 GB and even 12 GB of VRAM. GeForce GTX 780 Ti Black Edition cards are rumored to feature black cooler shrouds.
