    nVidia GTX 680 4GB video card - Comments....

    ALLENT Community Member

      I will be installing my new GTX 680 4GB this weekend... does anyone know if I will see a significant boost in speed & performance (in PP and/or SG).  I have 8-core (mid 2010) MacPro w/ 28G RAM (on Mountain Lion).  My stock 5770 is basically unuseable for any serious work.  I'd love everyones thoughts on this.

          I'm really curious to hear your impressions.  I have a 2009 MacPro and I upgraded from the stock card to the GTX285, and then more recently to the AMD 7950HD.  I was thinking of moving back into the nVidia world since CUDA still seems to be a better solution than using OpenCL. 

           

          But, with Speedgrade and Direct Link, we still have the following limitations: (taken from Speedgrade Blog)

           

          2. GPU acceleration for Direct Link
          SpeedGrade CC 7.2 extends GPU acceleration to the Mac when using Direct Link.

          Enabled: NVIDIA OpenCL (Mac) GPU acceleration is now available for OS X 10.8.5 and higher. This provides better feedback and real-time grading update when applying color adjustments.

          Enabled: AMD OpenCL (Win) GPU acceleration is now supported

          Note: GPU acceleration for NVIDIA CUDA and AMD OpenCL are not currently available on the Mac platform.

           

          I'm guessing this will change (hopefully soon) but it is a major roadbloack.  I'm still a little confused about how enabling GPU aceleration for OpenCL on nVidia, but not CUDA is a big difference.  I guess it hobbles the card's capabilities by not accessing the CUDA cores? 

           

          Please post your findings!

            Got it install without a hitch... and loaded a small 4k project into SG, and the scopes aren't reading and everything is sluggish... surely I have got something WRONG... I will start my research now, please add any comments or thoughts you may have... things should be WAY BETTER THAN THIS!!!!

              Related to my post above, is this SG project a Direct Link or a fresh project from scratch?  If it is a DL project, try it as a standalone and see if you notice a difference.

                It was a DL project, I thought if you loaded a project from scratch into SG you could only have 1 video track???

                  For the sake of testing, I would try it out on some of your footage by using a clean SG project and see how responsive it is.  If you look at the info from Adobe I posted above, SG will NOT be GPU accelerated at all in most cases for a DL project on a mac- as of right now.  That will change.

                   

                  Test it again with a clean SG project and see how it functions.  Worry about the multiple video tracks later.

                    Unfortunately, i did the same as you and spent $$$ on a new cuda card, replacing my 5770, thinking it would make everything better. It definitely did not. As others have mentioned though, this is mainly a problem with DL projects and not native SG timelines.
