There are two types of Bitcoin miners: those that run on powerful central processing units (CPUs) and those that use application-specific integrated circuits (ASICs). ASICs are purpose-built to do one thing and one thing only: mine bitcoins at mind-crushing speeds, with relatively low power consumption.
ASICs have been the driving force behind the dramatic increase in hashrate seen on the Bitcoin network in recent years. While a single CPU might be able to mine a few bitcoins per day, an ASIC can mine thousands or even millions of bitcoins per day.
The newest Bitcoin miner is the Bitmain Antminer S19, which was released in May 2020. The S19 is available in two models: the S19 Pro (95 TH/s) and the S19 (110 TH/s).
Both models are very similar in terms of specs and performance, with the main difference being that the S19 Pro is slightly more efficient. .
The Bitmain Antminer S19 is one of the most efficient Bitcoin miners on the market, with a hashrate of up to 110 TH/s and a power consumption of around 2920 watts. The Antminer S19 is also one of the most expensive miners currently available, with a price tag of around $4000.
While the Antminer S19 is the newest and most powerful Bitcoin miner currently available, it is important to remember that ASICs are subject to obsolescence. In other words, newer and more powerful ASICs are continuously being developed and released, which makes older models like the S19 less attractive over time.
