No, that was the result.

Their goal was to get the existing PPro base to beyond 1.0GHz (although
they eventually got the originally timed design to 1.4GHz with a few
async tweaks).  The easiest way to do that was to extend the pipes and
massively increase the staging to make timing at higher clocks easier.
The result was massive inefficiency per MHz.

Umm, I'd expect someone without a semiconductor design background to
assume that.  ;->

There's more to memory mapped I/O than just the NIC and storage.  ;->

But yes, I agree, with 2 or less sockets, it doesn't matter quite as
much -- especially not with the newer Xeon designs.
