No, these are fair 32bit GFLOPs. No, VC4 do not throttle, power figures are given for the real max load. And I never managed to get close to 8 ins per cycle on A15, but, for example, an FFT implementation on VC4 is pretty close to a theoretical performance limit. And a fully loaded 4-core A15 will draw far above 500mW anyway.

It's one instruction per cycle that gets 8 flops. And what are you arguing even? Assuming its unthrottled FP32, that gives a quad-core A15 at 2GHz 7 watts to be over 5x less efficient.

  I'm arguing that if all you have is 1W, you've got no other option but GPU.
