FUD Zilla heard the upcoming GeForce GTX 465 graphics card is a cut-down version of the GeForce GTX 470. While the latter one has four graphics processing clusters, the new GeForce GTX 465 will have only three. Both GPUs have the same core and shader clockspeeds, but the memory configuration will be somewhat different.
The GTX 465 has 11 streaming multiprocessors while GTX 470 has 14. When it comes to CUDA cores GTX 465 has 352 while GTX 470 has 448. The number of Texture Units on GTX 465 is 44 while GTX 470 has 56. The GTX 465 has 32 ROP units while GTX 470 has 40.
The core clock on both is 607MHz GPU and the Processor clock (CUDA core) clock is the same for both chips, 1215MHz.
Moreover, the site also reports that the GeForce GTX 460 based on the new GF104 chip may make a bigger difference to NVIDIA's product lineup, this part is expected sometime this summer, but the exact launch date is still a mystery.
