RE:"Embedded processors are measured at 125C, AMD uses 95C, so how does Intel get off testing at 72C?"

So you are saying the P4 would fail if tested at 95C?
So the P4 has to run cooler? Why is this a problem if Intel can get the desired Mhz out of a chip tested at 72C?

Jim

"so how does Intel get off testing at 72C?"

Intel incorporates a thermal sensor that stops the
internal clock for 50% of the time if the die
temperature exceeds some point:

ftp://download.intel.com/design/Pentium4/guides/24920301.pdfSee pp.23-24

So, it works in two ways:

A) the P4 operates at effectively half of the specified
frequency when doing real job;

B) by using really enormous cooler.

SCUMbria - re: "AMD uses 95C, so how does Intel get off testing at 72C?"

What temperature did AMD spec the K6 and K6-2 to operate at?

Remember - their standard SPEC was a case temperature of 0 - 70C - until they hit 400 MHz - when the DROPPED it to 0 - 60 C?

Please re-post your cries of AMD playing FOUL when they pulled off those tricks.

Paul
