Title: about crypto-engines. Post by: Un zafado cualquiera on January 05, 2013, 03:23:52 AM some time ago i was looking for a CPU miner and there were a pair of miners using special instructions on it.
now,there is no miner using similar technics, and i want to ask: - why are these int deprecated? - how could it being ignored, even when thats help reducing CPU overload? - on ARM architecture, why this cannot be optimized to use these hash capabilities? -isn't it more power efficient?

CPU mining is dead. Even the biggest, baddest $1000 CPU's may only be able to crank out 30 mhash/sec while consuming on the order of 200 watts of power. Don't bother. By comparisons, you can get a retail Radeon 6450, a very slow, low end GPU for about 30 bucks and it will also do about 30 mhash/sec at a tiny fraction of power, probably in the area of 15 watts. You can also find a Radeon 5970, a very high end dual GPU card for about $250 and it will do 700 mhash/sec with about 200 watts of energy. Do not bother with CPU mining.
