Transcoding performance on different QuickSync chips

Hi,

we are planning to use Intel QuickSync for live video transcoding from 1080 down to 702,480,360. I measured performance on UHD 630 and Iris Pro Graphics P580 and was found that it's fairly similar performance. I expected the P580 to be noticeably better since it has dedicated video memory and more then twice the executaion units. Any insides on this ?

 

Cheers,

Martin

Hi Martin,

This should be based on the work load, you need to run multiple stream at the same time to take the full benefits.

The other item is the video memory, if you are still using system memory to buffer the frames in between the pipeline, you are basically blocked by the copying.
