NVIDIA may have drawn some flack for extending its "GTX" brand extension too far into the mainstream and entry-level segment, and wants its GK110-based card to stand out. It is reported that NVIDIA will carve out a new brand extension, the GeForce Titan. Incidentally, the current fastest supercomputer in the world bears that name (Cray Titan, located at Oak Ridge National Laboratory). Even as the GK110 silicon physically packs 15 SMX units, totaling 2,880 CUDA cores, the top GeForce Titan variant is said to use not more than 14, amounting to 2,688. This is probably to help maximize yields of the GK110 silicon. The chip features a 384-bit wide GDDR5 memory interface, 6 GB will be the standard memory amount. The target TDP of the SKU is set around 235W.
