one fpga mining x11 equal 10 card 280x speed,
but one fpga mining script only equal one 7850 card speed.
use fpga mining x11 coin can get a very high speed than gpu miner,that's why gpu miner can't get a good profitability for mining x11,because x11 net hash has many many fpga speed.
someone why know fpga,i think you know x11 can be very easy design by fpga,and if one fpga worth 100usd,the gpu miner at least use 1000usd video card can get a equal speed for fpga
Where is the proof/evidence that there is one working that efficiently? You posted a topic about people should stop mining X11 with gpu. Once you show the proof, then people will believe you. As the saying goes, "Seeing is believing" . Rumors and speculation aren't going to prove anything.
