That was a big question of mine and Thanks to Radiance, enlightened me.
Octane is using single precision calculations so Teslas or Quadro`s are not worth buying to use with Octane.
Buy as many GeForce`s as you can, Octane goes single precision
The thing I don't get is why the 580 is 10% faster then. The 680 has 1536 single single-precision cores, the 580 has 512 double-precision..... so is there a thread detailing what's going on from the dev's POV? If octane is truly single-precision then the 680's cores are only 1/3rd as powerful as the 580's. All I know is that my one 590 preforms at the same DP level as the new Tesla K20.
