    The ARM1136 is a substantially newer processor than ARM926 with new instructions for SIMD data operations, faster clock rates, brnach prediction and a better cache interface. It will, for most code, be faster than the ARM926.

    As with most of these things it is possible to construct code which will run slower - but providing you are compiling with ARM1136 as the optimization target you are unlikely to hit these cases.

    Cheers
