    Rkenosha Level 1

      Hi. Does anyone have any experience or knowledge whether there is a discernalbe perfomance gain by the 580 vs the 480? Also, any one tried the new 580 with 3 gigs memory. Thanks Roman

          Roman,

           

          The GTX 580 is slightly faster than the GTX 480, largely due to the 580's higher clock speed.

            With my PPBM5 testing I did find about 1 second improvement in my 1.5 GB GTX 580 on the MPEG2-DVD test.because that PPBM test is used for the scaling from 1920 x 1080 to 720 x 480.  With the Windows clock for our measurements being a 1 second clock it took many runs to verify that there was an improvement.  So if you already have a GTX 480 it is really not worthwhile upgrading (i should always add the qualifier that this was 5.0.3 version and I do not know if they can change the coding for improvements in future versions).  No experience here with the 3 GB version.  I did then overclock the EVGA GTX 580 with their EVA Precision tool and even with all three clocks at the maximum found absolutely no improvement in that score.
