Clock speed is irrelevant at the moment until further optimizations.. my brother has an s4 and its as slow if not slower.
I've also used an L3: 600 MHz and it gets the same speeds as mine.

If it was down to clock speed, a 1.5/2ghz dual core device would be enouph.. without frameskipp.
Rule of thumb is you need about ten times the CPU of the system your emulating and that's using LLE, ppsspp is done using HLE.. therefor its a lot more optimized so that rule doesn't apply.
