15% more power and 25% more hash. That's a good 10% increase. I will buy that miner for 0.1 BTC if you will sell it. You can probobly sell 20-30 copies and earn a few btc's
Or, you could make a pledge address and when you reach the amount you like, opensource it.
I think that djm34 also has a faster lyra2rev2 and sp_'s got a faster quark: it would be interesting to keep a thread on those closed source optimization to understanbd where it's all going.
I might have some in the future as well, but I'd really like that it all ends in opensource at the end of the day. Let's not make nvidia a new amd ;-)
