The Pi does about 10MB/s over the network, I believe.

As for image manipulation, sadly, the Pi is fairly fast by embedded standards, but running general-purpose software on a full-blown OS takes a lot away.

For comparison, the original Xbox used an x86 of the same clock speed.

Which is why we any predefined image manipulation should avoid the ARM core and jump straight to the rather powerful GPU. I think it even supports OpenCL, so there should be software out there that could work with it.

The GPU on the Pi can't/won't support OpenCL. That doesn't stop one from writing a GPGPU program in GLSL.

which is fairly useless as a point of comparison, as not only is it the completely different arm architecture, but it is also Arm V6 (arm11), whereas even our smartphones have been arm v7 (cortex A8, A9, A15) for the last couple of years. If i had to equate it to an x86 clock speed, i'd say 400mhz was possibly a fraction generous.

Sure, they aren't the same, but they ought to be in the same ballpark.
