[hpsdr] [Discuss-gnuradio] Intel Atom is NICE.

[John Miles]

Larrabee, I'm thinking, will be the real SDR platform of choice.  A Larrabee
box with USB 3.0 is going to put a staggering amount of DSP power into
peoples' hands.  It won't even make sense to mess with FPGAs at that point,
I hope.

GPUs are unquestionably an interim hack; I don't think they'll live to see
the next decade.  They'll go the way of the Weitek.
