On an a500/2000 class machine, the bus speed is well matched for the processor.

On anything that's more advanced, you have to be running in 32-bit fast RAM for the CPU to go anywhere near its full speed. Even if you're running a 50mhz 68030, if the processor has to hit chipram or any of the chipset registers, it has to slow down to 7 Mhz.

On top of that, the Amiga uses planar graphics architecture, whereas almost all emulators use "chunky" pixel architecture, which adds another layer of software execution to the emulator.
