Back in May of 2012 NVIDIA released information on GK110, a new GPU that the company was targeting towards HPC (high performance computing) and the GPGPU markets that are eager for more processing power. Almost immediately the questions began on when we might see the GK110 part make its way to consumers and gamers in addition to finding a home in supercomputers like Cray's Titan system capable of 17.59 Petaflops/s.
Nine months later we finally have an answer - the GeForce GTX TITAN is a consumer graphics card built around the GK110 GPU. Comprised of 2,688 CUDA cores, 7.1 billion transistors and with a die size of 551 mm^2, the GTX TITAN is a big step forward (both in performance and physical size).
From a pure specifications standpoint the GeForce GTX TITAN based on GK110 is a powerhouse. While the full GPU sports a total of 15 SMX units, TITAN will have 14 of them enabled for a total of 2688 shaders and 224 texture units. Clock speeds on TITAN are a bit lower than on GK104 with a base clock rate of 836 MHz and a Boost Clock of 876 MHz. As we will show you later in this article though the GPU Boost technology has been updated and changed quite a bit from what we first saw with the GTX 680.
The bump in the memory bus width is also key, being able to feed that many CUDA cores definitely required a boost from 256-bit to 384-bit, a 50% increase. Even better, the memory bus is still running at 6.0 GHz resulting in total memory bandwdith of 288.4 GB/s.
