I don't have enough background in multithreading yet, but it should be an issue of concern. Something tells me that in heavy multithreading application, the slower core will bottleneck the other cores.

Not necessarily, take Cinebench for instance. It will continue on with it's rendering of an image even if one core has slowed down rendering part of the scene. You can clearly see this in the Cinebench benchmark. Any good multithreading program should be able to do this. Of course, it's easier said then done.
