I have been using a NVIDIA GT730 graphics card which gave an improvement in transcoding times and subsequently writing times to disc as the file size was significantly smaller.
An example is a Partial copy with CloneBD, using hardware acceleration, where the file size is 25GB. After transcoding the file size is 12GB. My understanding being the padding is removed during the process.
A recent purchase of a NVIDIA GTX 1060 6GB employing 1280 Cuda cores, as opposed to the 384 with the GT 730, gave me the impression I should see faster transcoding times. However, currently that is not the case. What I see is, about the same time as a BD not requiring compression. This is probably correct as the 25GB has been transcoded to 20GB.
In conjunction with this the CPU usage is on average 37%, suggesting it is being employed a lot of the time as opposed to the GT 730, which only shows CPU usage of 5% (with hardware acceleration).
Is there an explanation for the different final file sizes that I am seeing and should I be adjusting a setting somewhere?
