You missed that bit,
up to 21 Million hashes with the current design at 18 watts which is 440%-1083% more efficient than equivalent GPU cards on the market.
and dont count on AMD for big bump in speeds.
Back in the days i started designing my own fpga board for bitcoin mining but appropriate fpga chips were difficult to find and also ASICs came out. But maybe its time to start the project again, hope public bitstreams for fpga will be available dont mind paying devfee.
