GeForce GT 645 

For the next seven years, supercomputing performance will have to climb by a factor of 50 over Titan and there is reason to believe that the industry can achieve this goal.

The computer is expected to deliver about 10 times the computing performance of ORNL's Jaguar supercomputer, which is currently listed as the world's sixth fastest supercomputer with a maximum sustained performance of 1.94 PFlops.

It is a single-slot, low-profile graphics card with 384 CUDA cores, 128-bit wide GDDR3 memory interface, 875 MHz GPU clock speed, 891 MHz memory clock speed and TDP of 50 W. When compared against the low-end GT 640, the GT 630 is actually the better card and in-turn will offer users better performance in their OEM system.

It is based on the Fermi GF116, which features 144 CUDA cores, 1.5 GB or 3 GB GDDR3 192-bit memory interface, 720 MHz core clock speed, and 891 MHz memory clock speed.
