GF104 full version is the gtx475?
GF104 new core will be built the full array of 8 groups of SM, while the core of the current GTX460 powered by only 7 groups. Since July, NVIDIA GF104 equipped with a core GTX460 received no small influence, but with the release of new competitors, NVIDIA three months to establish the influence is gradually reduced. Now, NVIDIA has no time, they need to have 8 groups of SM GF104 array core product released, has more influence.
We know, including GF104/106/108 core, including, in each of their core SM CUDA array contains 48 core units and 8 SFU (Special Function Units, special function modules). The new product will be a complete set of SM 8-core CUDA array of 384 and 32 SFU units by others. Therefore, CUDA than the GTX460 will be the core increase the number of 48.
In addition, the texture units may also be increase from 56 to 64. Complete array of 8 groups of products in the performance of SM is likely to be easier than on the GeForce GTX 470, but price to 200 dollars or even less GTX470 is quite worth buying, of course, which is based on the TDP and you do not care about their 215W the premise.
