Kap, <Don't forget that part of the penalty is increased when the branch target is outside of Execution Trace Cache. Not only the pipeline is flushed, but also the execution trace has to be decoded into the Trace Cache.>

So what? That's no different from a regular instruction cache.

<I think that it was you who said that P4 retained the clunky PIII decoders running at half the speed (700MHz for the 1.4GHz part) of the core.>

You must be mistaken. I never said that.
