More like 2.4 Ghz. The GameCube and Wii are basically the same hardware, and Dolphin has been around now for since about 2003, so the developers have had a lot of time to get things running.
Dolphin code is more CPU intensive than a regular PC game that relies on a stronger GPU than CPU. This is because Dolphin translates the PowerPC code that GC and Wii games have into x86 code that PCs use.
Most modern CPUs can run Dolphin at playable speeds, except for CPUs that are 1) old by computer standards (like pre-2008), or 2) low voltage CPUs
CPUs with the "U" or "Y" at the end are low voltage, and are clocked very low. They don't have great speeds for an advanced emulator like Dolphin (or PCSX2).
The non-low voltage Intel Core i series past 1st gen CPUs, and the upper end AMD FX/APU CPUs can run mot games at playable speeds.
