In order to find out if your NVIDIA GeForce graphic cards support NVENC technology, process as follow:
- Check what is the exact name of your graphic card, e.g. "GeForce GT 640M LE"
- Go to this Wikipedia page, search for the exact name of your graphic card in the comparison tables and note the codename(s) of your graphic card: https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units
- If the codename of your graphic card begins with GK (Kepler microarchitecture), GM (Maxwell microarchitecture) or GP (Pascal microarchitecture) then your graphic card does support NVENC; if not then your graphic card does not support NVENC.
Here a few examples:
- The GeForce GTX 660M has the codename GK107 and does support NVENC
- The GeForce GTX 670M has the codename GF114 and does not support NVENC
- There are five versions/revisions of the GeForce GT 640. One version has the codename GF116 and does not support NVENC. Three versions have the codename GK107(-301-A2) and one version has the codename GK208-400-A1; all these four graphic cards do support NVENC.
