[time-nuts] Raspberry Pi Competition...

[lists at lazygranch.com]

It is hard to say which Arm is best for time nuts. The Cortex-A8 is  what the Beagleboard XM uses. That CPU has "neon", which is Arm's version of MMX. That is, not fully kosher floating point, but fast parallel processing good enough for DSP. The Raspberry Pie uses a fancier GPU and a simpler CPU (no DSP in the CPU). If you are compiling your own code with gcc, there are many options specific to the "neon" architecture. (It is on the TI website.) I've been doing some SDR on the Beagleboard XM, and the difference can be a factor of 3 in CPU utilization.
