NVIDIA's newest product designed to strike the price-performance "sweetspot," the GeForce GTX 660, is set for a mid-August market launch, according to a SweClockers report. The new chip could roll out some time between August 13 and 19. Given that other Kepler-based SKUs have been launched on Tuesdays or Thursdays, it's likely that the launch date could be either the 14th, or the 16th. The GTX 660 will be based on the 28 nm "GK104" GPU. It will feature 1,344 or 1,152 CUDA cores, and a 192-bit wide GDDR5 memory interface, holding 1.5 GB of memory, according to the report. The new GPU could capture a crucial sub-$300 price-point.
