re: Joe
sorry, I need some coffee :-))
re: That's a 20% difference?
That point did not escape me and it does not add to my comfort :-)) but my point was that given that dP/df "jumps" even within one processor type you might need a bigger sample to get to anything that might be conclusive. Again, I looked at it as samples without regard for the business so I obviously ignored anything that cpu specific - non my area of expertise.
re: I chose 7 benchmarks fairly arbitrarily
you were completely fair about it, what I referred is actual frequency points. Even if there is such a thing as "true" dP/df can you really say that the results are conclusive given that in a small set you encountered at least 2 ouliers
I know that std is not really at issue here but it needed to establish degree of confidence
re: it does show that AMD needs to either change its quantispeed formula
since model numbers are compared to intel frequency then I agree with you. But I recall that at the QS intro someone at AMD said that they would use simplified formula over some rage of frequencies and adjust the formula when needed so, at this point, I do not see amd disagreeing with you on that either. Should they change it right now or let it go for another few speed grades would make very little difference
