On modern Intel and AMD processors, the emulator performance scales more or less proportionally to the host processor frequency. Thus, a host processor running at 3.5 GHz will ~15% better performance compared to a host processor running at 3.0 GHz. As the frequency of the host processor drops we see a non-linear deterioration of emulator performance and very low frequencies may lead to inability to run the guest OS. We strongly reccommend not going below 23.0 GhzGHz except in rare cases in which the original processors have a very low frequency.
The emulator performs best on the most recent Intel and AMD processors.
