An industry-standard size of 410 X 170 X 209mm, S21 Hyd is comfortable to mine from anywhere.Bitmain’s Legacy and the Antminer Series
Since its foundation in 2013, BITMAIN is the world's leading manufacturer of digital currency mining servers through its brand ANTMINER, which has long maintained a global market share and leading position in technology, serving customers across over 100 countries and regions. The company's R&D center is situated in Singapore, and it has multiple branches and subsidiaries across the globe, including but not limited to Hong Kong, the United States, Malaysia, Kazakhstan, the United Arab Emirates, Lithuania, and Paraguay.
Comparison with WhatsMiner M63S
The Bitmain Antminer S21 XP Hyd (473Th) offers a higher hash rate of 473 TH/s and lower power consumption at 5,676 W compared to the MicroBT WhatsMiner M63S, which consumes 7,215 W. The S21 XP Hyd operates within a wider temperature range (5 - 45 °C) and has a broader humidity tolerance (5 - 95%), making it more versatile for various conditions. While the M63S is larger and heavier, the S21's efficient hydro-cooling design may provide better thermal management. Overall, the S21 XP Hyd is likely the more efficient option for serious miners, especially in terms of energy efficiency and performance.- Processing&Shipping Time
