They have been talking about this (CSI) for years ... mmm ... what is the
latest on its arrival and the details on functionality and width-by-clock
performance envelope (I have forgotten waiting)? The multi-core multi-socket
revolution is happening now ... ;-) ...

Yesterday's capability is todays capacity ... anything on a desktop is no
longer a "supercomputer" ... ;-) ...

The questions here is how large will the cores be, how long will the cross-bar
switched interconnect scheme last on the chip, will we be able to program the
on-chip interconnect (will we get more instuction additions to the x86-64 ISA),
and how will on-chip memory technology change to support the many cores.

As a processor, it is now counter culture ... it is IBM successfully beating
its chest and saying that we can still push up performance along the dimensions
of increased clock and ILP (not withstanding the in order execution).
