In early October 2024, Bitmain announced an improved version of its basic SHA-256 Asic Bitcoin mining miner called Antminer S21+ and its more advanced liquid-cooled version Antminer S21 + Hydro. Recall that Bitmain introduced the original version of Antminer S21 a little over a year ago in September 2023. Compared to last year's model, the S21+ has higher energy efficiency and hashrate, but is still lower than the Antminer S21 XP version announced a few months ago. (Bitmain Antminer S21 XP HYDRO is the new leader in energy efficiency of Bitcoin mining)

The updated Bitmine Antminer S21+ 2024 Asics offer slightly improved performance compared to the original 2023 versions by about 10% and are likely to become the base option for ordering instead of the initial 2023 models, as was already the case with previous generations of ASIC miners from this company.
