The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology. The 16 nm fabrication process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices.
Although a 10nm process is on the horizon antminerfurther increases beyond that remain theoretical.
Further, the design and manufacture of any 10nm Bitcoin mining hardware is likely to take at least a year. The good news is that existing power supplies, at least those of sufficient wattage, are fully compatible with the S9. A total of chips, spread over 3 circuit boards, are combined to achieve this phenomenal hashrate.
Note that Power Cost will be specific to your location and that Difficulty changes every 2 weeks, usually to the upside…. Your Pool Fees will be determined by your mining pool; although the S9 is plenty powerful, a single unit is highly unlikely to find any blocks when solo-mining.

Feedback If you are a seller for this product, would you like to suggest updates through seller support? While S9s cram in greater efficiency with more chips, those chips were prone to failure due to running at minimal voltage.
The T9 chips antminer at higher voltage, which means less efficiency but greater reliability.
For people with an extensive array of miners, greater stability can be worth the efficiency hit. It means less resets, less maintenance, less downtime, less mining time wasted on repairs antminer replacements, and less aggravation in general.
The T9 was sold with a day warranty, which is obviously twice as good. That said; the next batch of S9s will also feature this day warranty. If purchasing from eBay or similar sites, look for sellers who provide their own warranties.
If you own a PSU of an old Bitcoin miner you might be able to use that as well. Seeing as most people will probably rush to buy the new Antminer s9 you may want to consider getting the older model Antminer s7 at a discounted price due to lower demand. My overall rating is a 3. These are great miners that can replace about 3 s7s. However, the miner gets way too hot over the s7s. If you do want to use the s9s then they will have antminer be in a much better controlled environment which I will have to come up with if you want to keep these lasting longer.
Bitmain delivers their Bitcoin miners in batches. Antminer batch is different than the other and also has a different hash rate.
