It should be said that 720 1A comes out later than 7200, and the main frequency is the same, but the function is slightly lower than 7200 (the execution efficiency is the same).
According to the information found by ESATO, CPU MSM720 1A originally did not exist. Because Qualcomm lost the lawsuit against Broadcom, some changes were made on the basis of MSM7200A to avoid infringing on Broadcom's patent. Therefore, the video playback and recording performance of MSM720 1A is lower than that of MSM7200A. This is reflected in Diamond and Touch Pro, two mobile phones with MSM7201A. The video recording of these two mobile phones can't reach VGA 30fps, and they don't support H.264 format recording. You can use MSM7200A to record VGA 30fp MPEG-4 and VGA 15fps H.264 videos. Hardware decoding H.264 VGA 1.2Mbps 30fps video. 720 1A cannot play H.264 video.
