Wii games running much slower than GC

Most AMD processors have worse performance per clock cycle compared to first, second, third and fourth generation Intel i3, i5 and i7 processors. AMD processors generally have worse single threaded performance than recent Intel offerings and aren't capable of crunching as many instructions per clock cycle. Decent performance is achievable with AMD processors depending on your hardware, the game you intend to play, emulator options and clock speed (try overclocking) but recent Intel processors, Haswell especially are going to be top performers for CPU intensive emulators like Dolphin even at lower clock rates than AMD processors.
