I currently have two offers for buying antminer s9. One with a 22nm chip and the other with 14nm. Can somebody give be the pros and cons for both, because i understand that the power consumption would be bigger with the 22nm, but will that mean that i will be mining less than the 14th/s -+ 5% ? or will the electricity be only different. Hoping to have a good response and answer from you, thanks.
14nm will hash more with the same power consumption of a 22nm assuming your basing it on power only. But if both were 1/ths the 14nm would save more electricity. Obviously the 14nm would cost more as its newer tech. You'd have to weigh your electric cost vs hashing power.
