GeForce GTX 485 is rumored to be the heir to the throne of the Nvidia Fermi family. The new top model is said to launch this fall sporting 512 healthy CUDA processors and slightly higher clock frequencies for both GPU and shaders.

The information posted by Hardware-infos is said to come from Nvidia’s chief developer Bill Dally who revealed that the new GTX485 model is planned to launch this year.

GeForce GTX 485 wil be the first Fermi card with all working processor clusters, 16, which gives it 32 CUDA processors more than the flagship GeForce GTX 480. It will also bring 20 MHz higher GPU clock and 40 MHz higher shader clock. The number of ROPs are still the same, 48, but 4 more texture units are now active.

This is in no way an official statement by Nvidia and should be considered with a pinch of salt for the time being, but it would be nice if Nvidia and TSMC finally got the 40nm circuit under control and be able to raise the bar a bit. While on a positive note, the new cooler is said to be more efficient and quieter. The price will be a couple of tens higher than the introduction price of GTX 480.
