For my own system I get this:

code:
KiXtart 2001  4.12 Beta 2
Reports My CPU as: Intel Pentium III
Reports Speed as: 547

On this system all 3 reporting methods are close enough for reporting purposes.

I have training on Monday/Tuesday so will not be able to get out and check the ones reporting as Celeron until middle of next week.
