"...you're chip runs at 67W +/- at full load I belive. Where are you getting your values from?"
There is a VERY common misconception that TDP is an actual power value...it is NOT! TDP is a temperature guideline for OEMs...nothing more.
For example, Intel sets their TDP based on what they consider to be the most likely conditions, and AMD sets theirs based on absolute theoretical max. The results are that Intel CPUs often exceed their TDP, and AMD CPUs never ever hit theirs.
If you want to see actual power usage numbers, you have to actually measure them (something neither AMD, Intel nor most review sites do).
Lost circuits did just that recently on some of the AMD CPUs...

Notice that the Venice core under full load runs at ~30w, while the Newcastle core is more than double that...
Of course the P4 would be about triple, but I don't know if anyone has actually done those measurements so I can't say for sure...

BTW, I have a new Venice core system for a backup, and nothing I can do (short of overclocking) will get the temp (using stock HSF and 1 case fan) over 32C...the average temp is ~27C<P ID="edit"><FONT SIZE=-1><EM>Edited by viditor on 06/20/05 07:54 AM.</EM></FONT></P>
