maximum speed of a thread

Postby Gravis » Thu Apr 26, 2012 9:07 am

i've read some of the documentation and seen the chips have a guaranteed minimum speed of a thread is 100MHz when you have 4 threads or less. is this also the maximum speed of a thread or can they use the full 400MHz from a core?
i'm pretty sure it's 100MHz max but i would like to know for sure.

With n threads, n <= 4, each thread can get max 1/4th of the available processing time.
with n > 4, each thread can get at least 1/nth of the available processing time with the max of 1/4th of the available processing time. This means that when you run only a single thread, you can only use 1/4th of the available processing time and no single thread will ever get more than 1/4th of the available processing time.
