[Libva] Can we expect better GPU performance on braswell(Intel celeron N3160) than baytrail(Intel celeron J1900)?

[ViruS Tadala]

Hi Peter,

Thanks for your quick response.

Mentioned figures are GPU load values. I have ran the intel_gpu_top command
to get the same.

I didn't check any clock details. Used below pipeline and ran multiple
instances.

gst-launch-1.0 videotestsrc is-live=true pattern=22 horizontal-speed=20 !
'video/x-raw, format=(string)I420, width=(int)1920, height=(int)1080,
framerate=(fraction)10/1' ! vaapiencode_h264 min-qp=20 ! queue !
vaapidecode ! queue ! appsink

Please let me know if you need more information.

Best Regards,
Veeranna.
