The Bitmain Antminer S19 Pro is the most recent ASIC miner from Bitmain and provides up to 110TH/s. This is a marked improvement from the S17+ at 70TH/s. At 3250 watts power on the wall, it's, of course, a bit higher than the S17+ but the increase in the hashing capability more than makes up for it.
The increase in hashing power is about 44% while the increase in wattage is only 14% thus the power costs are far outweighed by the increase in hashing power. Remember, the greater the hashing power the more likely the machine is able to solve the hash for the current block and then be rewarded with a coin.
The main challenge with the S19 Pro is just getting them. Due to Covid-19 the normal supply chain for these miners has been disrupted immensely. If you look at their website you will find that while the S17's will ship in January of 2021, the S19 Pro won't ship until August of 2021. That's a long wait. Fortunately, BlockCap has pending orders on the books that will see arrivals of new miners well before that date.
While it's still profitable to mine with the S17 miners, the S19s truly are the way to generate maximum profits given the same energy inputs.
