The GTX 580 does not use an entirely new GPU, but rather an optimized version of the GF100 core dubbed the GF110. This GPU consists of 4 GPCs, 16 Polymorph engines, 64 Texture units and 512 CUDA cores. Most of these specifications are similar to the GTX 480, as both have the same amount of GPCs, Polymorph engines and Texture unites, but with the GTX 580 NVIDIA has maxed out the available CUDA cores. This means through optimization, we are finally able to see the full power of the Fermi architecture.
