Titan is based on NVIDIA's GK110 GPU, previously released on a Tesla-branded product for the HPC market and in the Titan Supercomputer, which uses almost 19,000 of the GPUs to crunch numbers at a brisk 20 petaflops. The GK110 is comprised of roughly 7.1 billion transistors, which is over three times the number of transistors in Intel’s Sandy Bridge-E based Core i7 processor. The GK110’s original design features 15 SMX clusters, each with 192 single-precision CUDA cores and 64 double-precision cores, for a grand total of 2880 SP cores and 960 DP cores, but one SMX is disabled in every GK110, bringing its workable core counts to 2688 (SP) and 896 (DP). The GK110 GPU also features 224 texture units, 48 ROPs, 1.5MB of L2 cache, a 384-bit memory interface, and a whopping 6GB of GDRR5 memory at an effective 6GHz data rate. The GeForce GTX Titan will easily be the most powerful single-GPU powered graphics card available when it ships, with relatively quiet operation and lower power consumption than the previous generation GeForce GTX 690 dual-GPU card."
