Thanks for your reply - but actually the question was what is the max throughput (bandwidth) of the M7 when accessing the system RAM (x Mbit/sec)

Hi jochengerster,

Theoretical maximum bandwidth can not be achieved in real device due to internal

buses and arbiters limitations. The total memory bandwidth in use (read+write) is around 480 MB/s which would make sense as we associate it with the bandwidth used by the framebuffer being displayed.

Regards
