It's hard to make such statements about a certain PC emulating a certain level of phone. There are a lot more factors at play than pure CPU clock speed when determining end user performance. Things like the memory bus speed, the speed of flash, cache sizes, cache replacement algorithms, adjustable clock rates, etc. Many of those factors are not emulated, so it's not really possible to make comparisons from the emulator to any given non-emulated hardware.
