Antminer Announced S15 And T15 7nm Miners

Bitmain, the leading manufacturer of mining equipment, started selling its new ASIC miners for Bitcoin mining — S15 and T15 based on the 7nm mining chip.
According to the info posted on the official website, the Antminer S15 has just been confirmed to have an estimated hashrate of 28 TH/s and power consumption of 1596 W with a price tag of $1475.00
The Antminer T15 has also been confirmed to have an estimated hashrate of 23 TH/s and power consumption of 1541 W with a price tag of $913.00.
Bitmain announced the specifications of these miners via a press release. In the past, ASIC-based mining devices were either performance oriented or focused towards saving energy. However, both, the Antminer S15 as well as the Antminer T15 Bitcoin miners come with two modes – high performance mode and energy saver mode.
According to Bitmain log, for large mining farms, both modes are easy to implement as an all-in-one design of miner with PSU and can be set up vertically or horizontally, making it flexibly adapted to different mining farms and miner racks. With the new high conversion power supply APW8, 16-18V high-voltage output, new miners can effectively reduce the power loss during the power conversion process, helping mining farms save on electricity costs.

It is noteworthy that the previous Antminers for Bitcoin mining were S9j и S9 Hydro.
