An emulator requires hardware 10x more powerful than the emulated device.
It is not always true I can run playstation1 games directly from my phone even though it is a budget phone so it isn't always 10x bigger. Amount of times more you need power is depends on how good your emulator/bios is and how complicated structure of emulated system. One more phone example: nintendo DS isn't very powerful game console however it can't be runned even on the most powerful android phones/tablets because there are no good emulator and DS's structure differs a lot with phone's one.
