[LAU] CPUs for low latency

At least for their FX eight core cpus, two cores share one floating 
point unit, so ever since early 80x86SX times, where you could buy a 
dedicated 80x87 FPU, those are not to be considered "full" cores any 
more. Though ought be complete asides the FPU, and therefore a little 
more "true" than HT.

Not sure however, if that matches your idea of a shadow CPU

Happy modern times. Penis competition about virtual cores. Because it 
sounds the same and is cheaper.

Thanks for the links, haven't had time yet to read them, though.
