The S9’s 16 Nanometer Technological Advantage
The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology.
Many have remarked that Moore’s law no longer holds true, as the rate of computing speed advancement has slowed as it reaches the physical limitations of silicon semiconductor 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 for 2017, further 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.
Recommended for use with the S9 are:
- The AntMiner APW-12 1600 Watt Bitcoin Miner PSU, which retails for just under $200 on Amazon.
- The EVGA SuperNOVA 1300 Watt GPU PSU, which sells for about $170 on Amazon. Note that the 1600 Watt EVGA PSU is significantly more expensive, by about $115, than Ant Miner’s equivalently-powered offering.
The cutting-edge manufacturing process is what makes the S9 the most electrically-efficient mining device to date.
It uses a mere 0.1 Joules per Gigahash, making it roughly 2.5 times more efficient than the Antminer S7.
The total power consumption of the device works out to around 1350 watts, although this figure is subject to about 7% of variance. The S9 consumes about 300W more than the S7.
Apart from the power supply, the S9 is a self-contained unit. It requires no connection to another computer to interface with other Bitcoin nodes.
Its onboard web management portal allows for a simplified setup and maintenance process.
The S9 is air-cooled and its sturdy design is fairly easy to maintain and service.
The S9 performs reliably in any well-ventilated space, whether a single or several unit(s) kept in a spare room or hundreds to thousands of units in a large mining center.
