Guru3d has reported that specifications for the GeForce GTX 450, 440 and 430 have surfaced. The GTX or GTS 440 and 450 would have a 40nm GF104 core. This core has 256 shader cores and a 256-bit memory bus. The GTS 440 would have 20% slower clock speeds than the GTS 450. The GTS 430, using a cut-down version of the GF104, will have 192 shader cores and have a 192-bit memory bus. These video cards are reportedly due in June 2010. Tom’s Hardware investigated these rumors one step further:

Last week there were also reports that cheaper, DX11-capable Fermi-based GeForce graphics cards will be arriving sometime this summer, possibly June. We contacted Nvidia to find out whether this was the case or another churn in the rumor mill. According to the company, that is indeed the case, and was actually mentioned by Nvidia executives at a recent financial conference.
