Looking over these numbers, I think Android itself is doing too much processing under the hood, and it's not letting you assign task/thread priority. That would be very important for a benchmark. SetCPU does not appear to be working correctly on Nexus 7.

Something odd I'm noticing: peak MB/s never exceeds the device clockspeed. Maybe there's some clock-limiting going on at around 1MB/MHz? That would explain the similarly equipped phone with the faster 2core CPU outscoring the tablet with quad.

Thanks. Unrealistic how? Too high or too low?

Interesting how much my S3 lags your S3

Sorry for the late response, but i felt the result are too high, although i can be wrong.
