I kinda wish it were possible to overclock a single core and be able to direct single-threaded processes to it. I understand how CPUs and clock speed works, I'm just saying it would be cool.

That said, as I sit here thinking about it, it might he possible to have a core that uses a higher-frequency harmonic as part of the architecture of the chip. It might need a larger L1 and some special transport architecture to step the processed data back to the lower clock speed, but I don't think there are any physical or computational reasons it shouldn't be possible.
