Very cool - I've been waiting for someone to figure out GPU computing on the Rpi for a while now. This is potentially a very substantial increase in available processing power.

I don't see performance numbers there - could someone with a Pi please run the FFT and compare against a CPU implementation?

I wonder how similar the Mali design would be. Obviously the technical details will be different, but would it be similar in broad strokes? Most Rpi-alikes have Mali 400s or 450s.

The RPi blog post about it [1] says about 10x improvement in performance over an ARM version. I haven't tested it myself but it seems reasonable.

It would be super-useful if this enabled something like beignet [1] to be ported to the vc4.
