Nvidia GeForce GTX Titan
There are graphics card, and then there are supercomputer-level graphics cards. Nvidia's GeForce GTX Titan is the latter. Introduced in February, the Titan is Nvidia's latest powerhouse halo product, and it packs a huge punch; the card features Nvidia GK110 28-nm GPU, which is coincidentally the same technology that powers the Oak Ridge National Laboratory's Titan supercomputer. The GeForce GTX Titan lives up to its namesake, too; the card features 2,688 Nvidia CUDA cores, 7.1 billion transistors, 4.5 teraflops of computing power and 6 GB of GDDR5 memory. Even with all that power, the GeForce GTX is somehow surprisingly quiet with Nvidia's "vapor chamber" cooling system and streamlined airflow design.
