Petz, <the FSB (effectively 200 MHz) does not have to be changed to improve memory latency.>

This contradicts with observations, and therefore
is a fallacy. The EV6 bus overhead does exist. The
"200MHz" is a good marketing ploy, but in fact all
bus transactions are still granular on 100MHz
clock and even worse. Thus the bus latency is
directly added to the memory latency. In addition,
there is so-called inter-domain "friction" if two
different clock domains are involved.

From the above it follows that the DDR will
not help either. Sorry to disappoint you and
some internal AMD platform evangelists.
It is really disturbing to see
how the (almost) brilliant processor design
is dying in hands of ignorants.
