Nom du Keyboard writes: It appears that Nvidia is abandoning relatively cheap high-end GPGPU performance for the masses with the EOLing of their Fermi GF110 GTX 580 chip. The new GK104 Kepler GPU excels at graphics tasks, but is a dog at the gold standard of double precision floating point computation, unable to best even the previous generation GTX 580 chip,, let alone AMD's latest Tahiti HD 7970 GPGPU. While certainly Nvidia will soon announce a vastly more expensive workstation and supercomputer class GPGPU solution with undoubtedly a significant performance increase over their previous generation, it now seems like AMD is the only option in the market for the home user on a budget wanting major compute in addition to stellar graphics performance.

algorithm that sometimes needs exponential space.
