I said "would be." The point it moot.

However the piccie gave me an idea where the form factors may make a quantifiable impact on performance.

Take one socketed MoBo with a single PowerCache Card and adapters for both the Proc Socket and the PDS. Test the two to see if there's a difference.

My money, all two bits of it, would be on the PGA Socket Adapter if it doesn't place the adapted proc even farther from system RAM & ROM that the PDS Adapter does.
