You would need to compare performance per watt for your particular application. If you just read the Box, a GPU uses 250 Watts, while an FPGA is tens of Watts.

You would need to compare performance per watt for your particular application. If you just read the Box, a GPU uses 250 Watts, while an FPGA is tens of Watts. But then consider that you are getting a large amount of very high speed memory and much higher clock speeds. Then once you take that into account, you can begin to start analyzing which is better for your project.
