An FPGA implementation on general-purpose fabric will not validate the performance/watt when compared to dedicated silicon. The two aren't comparable. This is part of the reason modern FPGAs have onboard ARM processors, as well as graphics and I/O peripherals.

No of course not. But it will validate benchmarks per-clock cycle, as well as providing a gate count (or LUT count) required to achieve that benchmark result. If the architecture is anywhere near as awesome as claimed, there should be a strong indication of that in the numbers produced by the FPGA implementation.
