According to news, Bitmain announced the release of the new Ethereum mining machine E9. The price, performance, and production capacity have not been announced yet. Bitmain's Ethereum mining machine is of the E series. The E3 design failed and coincided with the bear market, which caused a large number of stockpiles. Subsequent E series products are not sold to the outside world. In July 2020, the monitoring data of the Ant Sentinel website today showed that a mining machine named "E7" was mining, and Bitmain's Ethereum mining machine E7 was exposed from this. The maximum computing power of a single unit is about 800M, and the defective product is 500. -700M or so. There are rumors that the performance of E9 theoretically reaches twice that of E7.
