What Makes the BM1370 Series ASIC the Heart of Your Antminer S21 Pro/XP?
2025-12-02
When discussing peak efficiency in Bitcoin mining today, the conversation inevitably turns to Bitmain's Antminer S21 Pro and S21 XP. At the heart of these powerful machines lies a critical component: the BM1370 ASIC chip series. But many miners ask us: what's the real difference between the BM1370, BM1370BC, and BM1370AA ASIC chips for Antminer S21Pro and S21XP? My team at Shenzhen Xinjinyi Technology Co., Ltd. works closely with these technologies, and I'm here to clarify.
The Core Role and Impact
These specialized chips are engineered for one purpose: to execute the SHA-256 algorithm with maximum efficiency and minimal power waste. Their role is non-negotiable—they directly determine your mining profitability.
In our experience, the deployment of the BM1370 ASIC chip series in the Antminer S21Pro and S21XP has set a new industry benchmark. To give you a clear picture, here's how the models powered by these chips compare:
| Model | Rated Hashrate | Power Efficiency | Core Chip Technology | Our Advantage |
|---|---|---|---|---|
| Antminer S21 Pro | 234 TH/s | 16 J/TH | BM1370 / BM1370BC ASIC Chips | Perfect balance of efficiency & performance, offering the lowest total cost of ownership. |
| Antminer S21 XP | 255 TH/s | 15 J/TH | BM1370AA ASIC Chips | Peak efficiency, designed for large-scale farms pursuing ultimate performance. |
The advertised performance is not just theoretical; we see the above results consistently in the field. The improved thermal and electrical design of these BM1370 series chips means the hardware can maintain peak performance with remarkable stability.
Why Chip Selection is Critical
Choosing the right ASIC is the most important decision for your mining operation. The BM1370, BM1370BC, and BM1370AA ASIC chips for Antminer S21Pro S21XP represent the pinnacle of Bitmain's design. Their importance lies in future-proofing your investment. With rising global energy costs, the efficiency gains shown in the table translate into massive long-term savings and a stronger competitive edge. In my view, neglecting this detail is the biggest mistake a miner can make.
FAQ: Your Top Questions Answered
Q: What is the key difference between the BM1370, BM1370BC, and BM1370AA?
A: While all are part of the same advanced 5nm generation, the suffixes (like BC, AA) denote precise binning for optimal performance targeting. The BM1370AA ASIC chip, for instance, is typically binned for the absolute highest efficiency, making it ideal for the flagship S21 XP. This allows Bitmain to optimize each miner model for specific hash rate and efficiency goals.
Q: Why should I care about the specific chip version inside my miner?
A: You are investing in the data presented in the table. The precise BM1370 ASIC chip for Antminer S21Pro and S21XP inside is what guarantees you achieve that promised 16 J/TH or 15 J/TH. We ensure our clients get machines with chips performing at their optimal specification, directly impacting your bottom line.
Q: How does this translate to real-world profitability for my operation?
A: Look at the power efficiency column. Lower joules per terahash (J/TH) means more Bitcoin earned per dollar spent on electricity. The advanced BM1370 series ASIC chips in the Antminer S21Pro S21XP are designed to give you that exact advantage, making mining profitable and sustainable even in competitive market conditions.
