According to Chinese tech blog Expreview.com, citing "reliable sources", Nvidia is preparing a lower-end addition to its GeForce GTX 400 lineup that could come as soon as June 1 – just in time for Computex. The third Fermi-based offering will reportedly bear the GeForce GTX 460 name and should go against AMD's Radeon HD 5850 in terms of price and performance.
It is said to utilize the same PCB as the GeForce GTX 470, but featuring 1GB of GDDR5 memory connected via a 256-bit bus and presumably cuts specs across the board. By comparison, the GTX 470 has 1,280MB of GDDR5 RAM and a 320-bit memory interface. Interestingly, Expreview claims there will be no formal reference design for the GTX 460, with each partner free to make a slightly different version.
Previous rumors suggest that other cheaper Fermi derivatives based on new silicon could arrive around June as well. These include a GeForce GTS 450, 440, and 430 – all of them based on the 40nm GF104 core and priced under $200.
