Hey Wanna, would you please inform the numb**** idiots on
the siliconinvestor AMD thread that the "voltage droop" spec
in Intel datasheets is actually a tremendous benefit to those
poor slobs that have to design power converters. Real power
supply circuits and distribution paths have non-zero output
impedance
, i.e. more current you draw the more the voltage
delivered to the processor drops. That is basic circuits 101
and reducing droop means reducing supply output impedance.
That means thicker PWB traces, more and bigger caps, and
over engineering the converters. Intel acknowledges reality
and cuts the board guys as much slack as they can in spec'ing
the power supply to their chips.

BTW, I currently work in the design of controller chips for high
efficiency power converters so those poor slob's problems
become my problems. wink
