Running an FFT is a CPU intensive application, and not a bandwidth/IO restricted application. The comparison made here is likely not an accurate representation of throughput if only data stream to disk is the goal.

I run Gnu Radio on an Atom D510 system for narrow-bandwidth radiometry.

No way in heck are you going to be able to run at 25Msps for even a
*single* USRP2, let alone multiple ones.
   I tried a 25Msps usrp2_fft.py on my atom D510 system (which is
dual-core at 1.6GHz), and it couldn't keep
   up.
