if the 248 was 130nm, it would be several revisions older and have HT running
at 80% the speed as the 275. the older rev would mean some missing tweaks
to the memory controller, some core tweaks, and might even run the memory at
a lower speed/higher latency.
it's a bit of a shame AMD hasn't made DC opterons more attractive, price-wise...
