We considered that the only differences between two versions GeForce GTX 460 will be the memory capacity (768 and 1024 mb) and the bus(192 and 256 bits), and also the recommended prices values of ($199 and $229). Default frequencies of both versions will be equal to 675/1350/3600 MHz, the quantity of stream processors is equal to 336 pieces. According to some data, video card can be characterized by energy consumption level (150 and 160 W).
Associates report that the GeForce GTX 460 version with 1024 mb memory and 256- bit bus will use the not more compact and cheaper in production video chip GF104, but old GF100, which are used on GeForce GTX 480/470/465.
According to associate, the GeForce GTX 460 version with 1 Gb memory and 256- bit bus will have the limited life cycle, since to use of video chip GF100 on the video card cost less than $250 for NVIDIA is not so profitable.
