Antminer S21 XP Series – Product Highlights
Antminer S21 XP series is a step ahead of other Bitcoin miners for the following reasons.
- Ideal for various mining atmospheres
Antminer S21 XP is built to perform across diverse mining environments. Thus, both large-scale industries and small-sized local operations can leverage S21 XP for their Bitcoin mining needs. Ideally, Antminer S21 XP is known for its efficiency and is suitable for operating on single-phase electricity.
- Stable under Varied Temperatures
Mining hardware should be robust enough to withstand temperature variations. Antminer S21 XP is built to be stable and efficient in operating under varied atmospheric temperatures, from 5°C to 45 °C. Thus, miners can leverage the S21 XP series to work under various temperature conditions.
- Enhanced PSU and Firmware
Bitmain has always been known for its high-quality products. It pushed its limits this time as well and came up with significant enhancements in the power supply unit (PSU) and firmware of the Antminer S21 XP series. Thus, the PSU of the S21 XP series can withstand higher loads while reducing power-related problems like hanging, rebooting, shutting down, etc.
Moreover, the firmware has advanced features that control and monitor the ASIC’s performance effectively. For instance, the firmware allows automatic underclocking and overclocking, allowing optimal mining performance and efficiency under various operational loads and environmental conditions.
- Excellent Energy Efficiency and Hash Rate
Bitmain set itself apart every time by launching advanced ASIC miners with excellent hash rates compared to its previous models. The Antminer S21 XP series is no exception. It has a maximum hash rate and outstanding energy efficiency compared to its predecessor, the Antimer S19 XP. For instance, Antminer S21 XP has a maximum hash rate of 270 Th/s compared to its predecessor, Antminer S19 XP, whereas the energy efficiency is 13.5 J/Th when compared to 21.5 J/Th of Antminer S19 XP.
Thus, the Antminer S21 XP series takes the lead in revolutionizing the Bitcoin mining industry with its superior capabilities like stability to mine under various atmospheric temperatures, high efficiency, advanced PSU and firmware features. All of that makes the Antminer S21 XP series ideal for all miners, from beginners to professionals.
