4. Core Product Advantages
1. Optimized Energy Efficiency & Lower Power Consumption
Compared with the previous-generation BM1370 (15 J/TH), the BM1373 improves the energy efficiency ratio to 10 J/TH, reducing power consumption by approximately 33%. It cuts long-term electricity costs under the same hash rate, perfectly adapting to low-power home mining scenarios.
2. Advanced Process & Optimized Heat Dissipation
Equipped with a 3nm precision manufacturing process, the chip features higher transistor integration. Combined with the optimized heat dissipation structure of the S23 water-cooled miner, it generates much lower heat. It maintains a low-temperature state not only on professional water-cooled miners but also on small air-cooled DIY mining rigs, avoiding frequency reduction and downtime caused by overheating.
3. Stable Hash Rate & Powerful Comprehensive Performance
The single chip delivers a stable hash rate of 2.5 TH/s without obvious fluctuation. With industrial-grade factory calibration and strong anti-interference capability, it maintains a low failure rate and negligible hash attenuation during long-term uninterrupted mining.
4. Wide Compatibility for DIY Modification
With compatible pins and circuit logic for mainstream open-source home miners, the BM1373 perfectly fits popular Solo mining devices such as Bitaxe and Nerdaxe. It can be used for faulty chip replacement of old miners or the assembly of new high-performance home mining equipment, featuring low modification difficulty and high universality.
5. Original Factory Quality & Higher Reliability
Derived from the flagship Antminer S23 series, the chip has passed strict high and low temperature tests and continuous operation stress tests. With exquisite workmanship, its durability is far superior to ordinary niche mining chips, making it suitable for long-term personal mining deployment.
5. Main Application Scenarios
-
Home Solo Mining: Compatible with compact miners including Bitaxe and Nerdaxe, ideal for individual retail miners conducting small-scale Bitcoin mining;
-
Miner Maintenance & Replacement: Used to replace damaged chips and repair hash boards of Antminer S23 series miners;
-
DIY Custom Mining Rigs: Allows mining enthusiasts to assemble lightweight high-performance miners with balanced hash rate and energy consumption;
-
Small-scale Commercial Mining: Supports the construction of small computing power clusters with low power consumption to reduce operation and maintenance costs.
6. Product Iteration Summary
As an upgraded 3nm mining chip of the BM1370, the BM1373 achieves comprehensive upgrades in hash rate, power consumption and heat dissipation. Backed by Bitmain’s original technology, it balances professional miner performance and home device compatibility. With ultra-low energy efficiency of 10 J/TH, stable hash rate of 2.5 TH/s and excellent heat dissipation, it has become a cost-effective mainstream chip in the current SHA-256 DIY home mining field.
