_all_? that's patently absurd. I don't think there's anything wrong
with presenting one's own products in a good light, but please don't
be misleading. obviously, there are many applications which have
absolutely no use for bandwidth greater than even plain old gigabit.
equally obvious, there are others which are sensitive to small-packet
latency, which is not affected by DDR or dual-rail.
