Hi, All!

I have Freescale i.MX 6 Sabre SD and try to run gles2-gears with different settings.
I updated BSP for my board from 6.5.0 to 6.6.0, adjust screen.

My statistic:
             # gles2-gears -interval=0 -size=100x100
             1245 frames in  5.002 seconds = 248.900 FPS
             1244 frames in  5.002 seconds = 248.701 FPS

             # gles2-gears -interval=0 -size=200x200
             1444 frames in  5.001 seconds = 288.742 FPS
             1450 frames in  5.000 seconds = 290.000 FPS
             1462 frames in  5.000 seconds = 292.400 FPS

             # gles2-gears -interval=0 -size=400x400
             1620 frames in  5.002 seconds = 323.870 FPS
             1605 frames in  5.002 seconds = 320.872 FPS
             1624 frames in  5.000 seconds = 324.800 FPS

             # gles2-gears -interval=0 -size=600x600
             1170 frames in  5.001 seconds = 233.953 FPS
             1167 frames in  5.003 seconds = 233.260 FPS
             1168 frames in  5.002 seconds = 233.507 FPS

             # gles2-gears -interval=0 -size=1024x768
             878 frames in  5.007 seconds = 175.355 FPS
             877 frames in  5.003 seconds = 175.295 FPS
             877 frames in  5.003 seconds = 175.295 FPS

At the same time, I have the results of similar tests on Accelerator Kit based i.MX6Q Saber Lite:
             # gles2-gears -interval=0 -size=100x100
             3990 frames in  5.001 seconds = 797.841 FPS
             4151 frames in  5.001 seconds = 830.035 FPS
             4243 frames in  5.001 seconds = 848.431 FPS

             # gles2-gears -interval=0 -size=200x200
             6715 frames in  5.001 seconds = 1342.733 FPS
             6783 frames in  5.001 seconds = 1356.330 FPS
             6731 frames in  5.001 seconds = 1345.932 FPS

             # gles2-gears -interval=0 -size=400x400
             4484 frames in  5.001 seconds = 896.622 FPS
             4490 frames in  5.001 seconds = 897.821 FPS
             5611 frames in  5.001 seconds = 1121.977 FPS

             # gles2-gears -interval=0 -size=600x600
             2397 frames in  5.001 seconds = 479.305 FPS
             2407 frames in  5.002 seconds = 481.208 FPS
             2397 frames in  5.002 seconds = 479.209 FPS

             # gles2-gears -interval=0 -size=1024x768
             1275 frames in  5.004 seconds = 254.796 FPS
             1271 frames in  5.001 seconds = 254.149 FPS
             1275 frames in  5.002 seconds = 254.898 FPS

Processors on our boards are the same, why the performance is so different??

In attachment, graphics.conf that I used.
