"Cool'n'Quiet was not enabled on the Socket 939 motherboard.
What does that mean?"
if CnQ was enabled then the athlon64s would have had dramatically reduced power consumption in idle (as they clock down to 1ghz and lower voltage), however it would make no difference in the other tests.
"Can a 3800 clocked down to 3500 on a 130 be equal to a 3500 in every way for a test comparison?"
this is debatable, but essentially yes, and even if it isnt fair then it only makes the new 90nm process better as a clocked down 3800 is probably more efficient than an original 3500.
"Does he have a standardized method for measuring cpu temps?"
this makes no difference as long as he uses the same method for both systems, and as it was the same system for both tests but with the cpu swapped i think this is a fair assumption. he doesnt mention the temp of the P4 so there is no comparison problem there
"What thermal grease did he use?"
again, as long as it is the same in all tests then makes no difference, and as he measures power not temperature (well ok he does measure temp, but only in passing) then it really doesnt matter.
"Cool and quiet wasnt enabled on 939, but no mention of it on 754"
there is a reason he doesnt mention the 754, they are both 939!
"THis guy was nice in showing his test, but he failed to make it a real study of the thing."
actually it is a really good article, not perfect, but very good. you failed to study properly.
