FPGA power consumption

Hey guys, I'm doing a comparison of performance of FPGAs and GPUs, right now I'm looking at the power consumption part. So I use the PowerMonitor.exe provided by Arria10 package, and the power doe...

The power consumption will definitely change during computation; however, your kernel might be too fast/short for the reading to show up, or the the provided power monitor might not actually work correctly. I have written my own power measurement functions for non-reference boards based on the manufacturers' API, and I have seen differences up to 30 Watts between idle (but configured) and computing states on the FPGA.
