Any mining gurus want to speculate with me on what IntelliHash will be? I'm guessing something like variable difficulty - something that increases the nonce search space and cuts down on chatty communication. Or maybe just 48 bit nonces.
Im guessing its basically just software controlled over/underclocking and volting, and perhaps some other parameters not unlike KnC's "tuning suite".
Either way, a 20% performance increase doesnt warrant a long delay when the network is growing by almost 20% every week.
