I may be wrong on this, but isn't one of the main drawbacks of the GPGPU approach the high power draw? High end GPUs do seem to be quite thirsty. I've no idea if any FPGAs offer better performance per watt, but I wouldn't be surprised if they did.
EDIT: This article seems to suggest that FPGAs currently have an edge over GPUs when it comes to energy efficiency:

- Stubb 10y agoFPGAs win in latency and I/O performance. Colleagues are running FPGA systems that handle nearly 100 Gbps of data. FPGAs will also get you latencies down in the microsecond range.
- gh02t 10y agoPower draw with GPGPU is better per flop than normal CPUs, but not competitive with an FPGA tuned to a specific problem with the same equivalent throughout. I think FPGAs also win out in flexibility. GPUs don't integrate so well into e.g. the signal processing hardware for digital oscilloscopes (a common use for high end FPGAs) mostly because of latency and timing constraints.
