In April 2021, the Chinese company Bitmain, which specializes in various cryptocurrency mining hardware, officially introduced an amazing device called Antminer E9 to the world. This computer, so to speak, provided enthusiasts with an excellent opportunity – they could get a productive system for mining Ethereum and, according to the manufacturer’s promises, pay back (with a device price of 20 to 40 thousand dollars) investments in just three to four months of active work. Unfortunately, the device got to the release only now – yesterday, July 5, Bitmain representatives officially announced the start of sales of Antminer E9.
However, in almost a year and a half since the announcement, the device has noticeably lost in performance. At the time of the premiere, the manufacturer promised that the Antminer E9 will have an Ethereum mining performance of 3000 Mh/s. Accordingly, with a power consumption of 2556 W, the efficiency of the miner would be 0.85 J / Mhash – a very good indicator. And, most interestingly, then Chinese engineers promised that the performance of a specialized miner in the Ether area would be equal to 32 RTX 3080 video cards. Now that the device has gone on sale, its performance has noticeably dropped.
At the time of release, the Antminer E9 shows an Ethereum mining performance of 2400 Mh/s with a power consumption of 1920 W and an efficiency of 0.8 J/Mh. It may seem that the difference is actually not so noticeable, plus the power consumption has dropped noticeably, but in reality 600 Mhash / sec is an impressive drop. In addition, now the Chinese manufacturer claims that a specialized miner is already equal in performance to 25 RTX 3080 video cards. Why a device with such an impressive cost has lost performance since the announcement is an open question, because Bitmain does not officially comment on the situation.
And in fact, it will be extremely difficult to recoup this acquisition – most likely, it is unrealistic. And the point is not only that the cryptocurrency is now experiencing a terrible drop in value, but also that Ether should switch to an energy-efficient Proof-of-Stake mining model in August (if it is not postponed again). This means that it will no longer be possible to mine cryptocurrency using the usual method at the expense of video cards and other systems – instead, another mechanism will work based on the currency that users already have.
