GTX 460 superclocked
TouchuvGrey:
i currently am running two video cards a GT220 and a GTS 250, i have a GTX 460 ( superclocked ) on the way.
i intend to replace the GT220 with the GTX460 and put the 220 in my #2 machine. i will report back with
the results.

GTX 460 installed, i had expected that it would have been more like 900-950 GFLOPS peak.
Unless i am missing something it seems as if the GTX 460 will do less crunching than the
GTS 250 ( of course i miss a lot )

hi,
not sure if Boinc is reasing the Gflops correctly for my 465 either. It can go from 570->855->2553 Gflops in a day.
855 is the correct (nVidia's) rating for the 465, so I would expect your 460 to be around that mark as well
Check out http://en.wikipedia.org/wiki/GeForce_400_Series and you can see Wiki's rating there

If you're using BOINC v6.10.45 or later, it should calculate peak GFlops correctly for GTX 480 and GTX 470 - using the original Fermi (GF100) chip with 32 shaders per multiprocessor.
But the GTX 460 uses the GF 104 chip, with 48 shaders per MP. No version of BOINC calculates that correctly yet (although DA was notified on 17 July): You should add 50% extra to those reported GFlops values.
Edit - the GTX 465 is a GF100 card, so the GFlops should be right.

Thanks Richard,
I saw the post you made to DA on the Boinc_Alpha list, from what he said it sounds like nVidia, didn't write this in to their API correctly?
Also any idea's why Boinc would report my Gflops at 2253 Gflops?
