What makes you conclude this?  And if it is true, what is the
underlying mechanism for most of the major chip manufacturers moving
to dual core at similar times, fashion?

I ask seriously.  I actually know little about it, but my assumption
is that the chip designers are having difficulty taking an existing
chip using N transistors and figuring out how to instead use N*2
transistors to to double the performance by extracting more
instruction level parallelism out of serial code.  And that those
designers are therefore doing the obvious thing - giving up - and are
instead using those N*2 transistors to build to CPUs each with the
same old N transitors.

Is this model incorrect?
