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.
