Recently I adquired the GeForce 620M graphic card, trying to resolve a problem with my Adobe Premiere Pro CS4 software (Premiere suddenly stopped working, and the only problem was the graphic card, the NVIDIA GeForce 210 series I used to have).
In order to fix that, I buyed the 620 series, but in the Compatibilities page of Adobe (http://www.adobe.com/content/dam/Adobe/en/products/premiere/cs6/pdfs/c ompatibiltiy-list-premiere-pro-cs6-only-hw-compatibility.pdf), in any of the Premiere series, CS4, CS5, CS5.5, CS6..., appears the 620M graphic card, so my cuestion is if the card is too recent to admit Premiere Pro.
Employees and beta test people are not allowed to comment on any future Adobe plans
Any card will work with CS4 to send the display to the computer monitor
Hardware acceleration using CUDA cores is only available for CS5 and later
The official list is only updated as Adobe has staff time to completely test & certify any individual nVidia card... For many others, with at least 1Gig of video ram, use the nVidia Hack http://forums.adobe.com/thread/629557 - which is a simple entry in a "supported cards" file... again, this is ONLY for CS5 and later
Technically, the GT 620M should work. Unfortunately, it is based on a two-year-old lower-end Fermi GPU design, with only 96 CUDA cores, DDR3 RAM and lousy 28.8 GB/s memory bandwidth. The GT 620M is basically a renamed GT 530M. Thus, should you update to CS5 or later, you might not be able to take much if any advantage of the CUDA MPE GPU acceleration that such newer versions of Premiere Pro offer - if only due to that weakling of a GPU.
