    Changed out Quadro 4000 for GTX 770 - no change in performance

      I had to reformat and reinstall Windows 7 and my CC apps last week, and I'd been planning on changing out my nVidia Quadro 4000 for a GTX 770, mainly for the boost in CUDA cores, figuring from all that I've read over the years that there should be a boost in render and export performance in Premiere Pro.

       

      Today I did the swap out. Just prior to pulling the Quadro, I noted the render time for a timeline that I was working on. I deleted all previews and cleaned the media cache, and rendered the timeline. which took 1:12. I also exported to a 720P(matching my sequence size) H.264 YouTube profile with Max Quality and Max Depth set. That took 5:28.

       

      I installed the PNY GTX 770 4GB ('Enthusiast Edition', I must add), and performed the same tests. The results? No difference. At all. With all factors remaining the same, I'd assumed that the increase in CUDA cores would have boosted performance some, actually a lot.

       

      Have I been misreading all of the advice both here and elsewhere on CUDA performance?
