The XU4 is based on a multi-core ARM clocked at 2-ish GHz. You CANNOT
expect comparable performance from an SBC, low-power,
ARM chip as you get from an X86 clocked at the same rate. Different
I'm aware of an interferometer experiment running at 2 X 12.5Msps with a
B210. That's as much as it can do, and the flow-graph had to be
carefully tweaked to even achieve that.
