These 3 are given:

Balanced = 1 GHz CPU / 468 MHz GPU
Quick = 1.4 GHz CPU / 768 MHz GPU
Performance = 1.7 GHz CPU / 920 MHz GPU

However, it has two other, low-end settings.

Power Save:
Efficiency:

These two lower settings do save on battery, but you can't even emulate PS1 games with them properly. It makes me wonder what the clock speeds for those two are, though.
