Ahhh... the FPGA is actually 3x worse on power is what that says.

I'm really curious. I worked out the numbers based on those given, coming up with the same result that the author did.

Assuming a worst case scenario
DSP - 2Watts. I/O multiple index 1.0 (defined as a multiple of max possible in the dsp)
FPGA - 10Watts. I/O multiple index 10 (i.e 10x as many as the dsp)

Best case scenario
DSP - 3Watts. I/O multiple index: 1.0
FPGA - 10Watts. I/O multiple index: 100

As I see it, in the worst case scenario, that means the fpga has 10 times the throughput, at 5 times the energy consumption.
That seems to me to be 1/2 of the power consumption, or (10/5 =) 2x the energy efficiency.
Conversely, in the best-case the fpga has 100 times the throughput, at 3.3 times the energy consumption
That again, appears to be 100 times the performance for 3.3 times the energy - or (100/3.3) = 30.3x the energy efficiency.

Is there something I've foolishly overlooked here? I'm really quite perplexed by your assertion.
