I'm doing some graphics comparative tests between i.mx6s and i.mx6q.
My "benchmark" is an application written in Qt5.1.0/qml that does a lot of graphical transitions.
With the i.mx6s at 1080p HDMI the performances were not so good...and this was expected...then I tried with the quad core version (i.mx6q) and with my great surprise I noticed that in this case the performances were just a little better than with the solo version.
The main difference is that the CPU load is around 60-80% with the solo and around 10-30% with the quad.
Please can someone explain me why I'm not getting very good performances with the quad core?
Could it be a problem with DDR bandwidth?
