Never know what they can do. But the current max is 6 GHz by IBM for any core, right? :)
The majority of current hardware do per core frequency scaling (or bursting), but hw.cpuspeed is reporting the BIOS CPU speed (considering over and under clocking) for each core before the scaling happens, right? So going forward with such complicated CPU designs, top will lie or be misleading. What about 64+ cores (OpenBSD supports 64 cores!) and many of them idle with low frequencies? How do you display them? I tried it and like it as end user, its cool. Wait for other gurus to chime in.
