Hmm, do you have "boost" enabled in your bios? You may wish to turn it off 
as non-os control will change speeds on you if temperature gets too high. 
That may be why the top speed shows different. Boost is new on the intel 
chips, so if your system is even a year old, probably no boost.

I have not installed an RT kernel since 2.4 or 2.6 as the lowlatency 
kernel has allowed me good stable performance and still has all the 
drivers I have needed on any of my personal machines I have tested. The 
generic kernel is not good enough for me though.
