To my understanding the only way you'd see a performance benefit is if Dolphin were running on a machine with a PowerPC or some other POWER-based CPU, since most or all instructions would no longer need to be emulated, making it closer to virtualization. It'd be interesting to see old G3, G4, and G5-based Macs repurposed as deluxe GameCube and Wii emulators. Potentially Wii U too, but I'd imagine that would be restricted to tail-end models of multi-CPU G5 towers with the best GPUs those machines can handle.
