Mani, Re: "I am certain. And neither AMD or Intel is going toward listing TDPtype. From your own post, AMD says, "Thermal design power represents the maximum sustained power dissipated," and Intel says: "TDP is defined as the worst case power dissipated by the processor while executing publicly available..." PIIIM has specked two values, typical and maximum."
For someone who is so certain, you are wrong on both counts. I understand you have the credentials of 5 years experience in thermal design, as you explained to heatsinker2, but the datasheets are clearly saying something different than you. If you still want to disagree after this, then fine, but at least read what I have to say.
First, Intel's Mobile Pentium III spec discusses TDPtyp and TDPmax. You believe that Pentium III-M also uses both of these values. However, if you look here (page 65)
developer.intel.com
you will see only one value under Thermal Design Power. You also say that Intel does not list TDPtyp, yet in Note 1, it clearly says,
"TDP is defined as the worst case power dissipated by the processor while executing publicly available software
under normal operating conditions at nominal voltages that meet the load line specifications. The TDPnumber
shown is a specification based on Icc(maximum) and indirectly tested by Icc(maximum) testing. TDP definition
is synonymous with the Thermal Design Power (typical) specification referred to in previous Intel datasheets."
If you had included the entire quote, you would have seen the last sentance. Finally, you say that AMD also does not list TDPtyp, but you still decided not to include the entire quote, and reading the rest of it makes a difference. From AMD's datasheet (page 43)
amd.com
"Thermal design power represents the maximum sustained power dissipated while executing publicly-available software or instruction sequences under normal system operation at nominal VCC_CORE."
This is almost word for word the definition that Intel uses above. If the Pentium III-M is using TDPtyp (it says that it is), and AMD is using the same kind of measurement (almost word-for-word), that means that both are both using TDPtyp values. Now, I don't claim to have a complete grasp of just how this value is defined, but it is painfully obvious that no matter how it is defined, TDPtyp is the value that AMD and Intel are giving manufacturers to design their systems.
Now, Mani, you're an intelligent person. I know this because I have read a number of excellent posts from you on this board. I hope it doesn't come across as personal, then, when I say that I'd appreciate it if you'd set a better example as moderator by not patronising me, or likening me to a preschooler. There are many more constructive ways to deal with someone who disagrees with you, and I am not like some others that just want to give you a hard time. Unlike them, I am not here to put down AMD, but rather to set the record straight when it comes to Intel. I am under the impression that you can sympathize with this.
