I don't dispute that they equate to the same speed, but does it have the same end result, i.e. the CPU can do the same number of calculations per unit time? This is not a rhetorical question, I'm interested to know the answer. The fact that AMD say 95MHz & 3.5X but don't add "or 66MHz & 5X" suggest that they are not the same. Does the CPU actually understand being told to use 5X and if not, does it then not use *any* multiplier (and just run at 1X)? > Greg > -- > When replying to this message, please copy the original recipients. > For more information, see http://www.lemis.com/questions.html > See complete headers for address, home page and phone numbers > finger grog@lemis.com for PGP public key > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > -- FreeBSD - The Power To Serve http://www.freebsd.org My Webpage http://www.users.globalnet.co.uk/~markov _______________________________________________________________ Mark Ovens, CNC Apps Engineer, Radan Computational Ltd.
