Sorry if this has been brought up before, but why is it that CyanogenMod 11 is countless times snappier than TouchWiz ROMs, and much faster, yet has such a lower score on benchmarks?

On TouchWiz with quadrant standard , I get like 5400-6200, yet on CyanogenMod 11 I get 4200. On antutu I get a sad 8000-1000 yet on TouchWiz I get 14000-16000. TouchWiz is getting higher scores yet is very sluggish in comparison.

Could it be launcher related or kernel related? I do notice on CyanogenMod that larger tasks take longer than on TouchWiz.
