Review of the Bitmain Antminer S5: Efficiency and Power
Introduction
The cryptocurrency mining landscape evolves rapidly, and hardware manufacturers strive to deliver higher efficiency with each new model. Bitmain, a leader in this domain, has cemented its reputation with the Antminer series, known for its robust performance and reliability.
The Antminer S5 represents a notable step forward, offering improvements in speed, energy consumption, and user-friendliness. Whether you’re a seasoned miner or a newcomer, this review explores the design, performance, and overall value of the S5 in today’s competitive mining environment.
Unboxing and Initial Impressions
Packaging and Protection
Bitmain’s attention to detail is evident in the Antminer S5’s packaging. The miner arrives in a sturdy cardboard box, cushioned with bubble wrap to prevent shipping damage. This robust packaging minimizes risks during transit, especially for international orders.
Design and Build
Weighing only 6.5 pounds, the S5 features lightweight plastic side panels, a departure from the heavier metal casings of earlier models like the Antminer S3. This design improves airflow while maintaining stability. The open-top and bottom layout provides easy access for maintenance tasks such as cleaning or component replacement.
Despite concerns about the long-term durability of the plastic panels, their secure fit ensures overall reliability. The design’s practicality, paired with user-friendly power connections, simplifies setup significantly.
Technical Specifications and Key Features
Hardware Overview
The Antminer S5 is equipped with Bitmain’s BM1384 chips, delivering a hash rate of 1155 GH/s. With 60 chips operating at 12V, it provides a fine balance of performance and energy efficiency. Its compact dimensions make it a versatile option for various setups.
Power Consumption and Efficiency
One of the standout features of the S5 is its energy efficiency. During testing, it consumed between 560 to 590 watts, achieving a power efficiency of 0.51 J/GH. This low energy use allows miners to maximize profitability even during periods of lower Bitcoin prices.
Cooling System and Noise Levels
The S5’s single-fan cooling system effectively prevents overheating. However, its noise levels—comparable to a household vacuum cleaner—make it less suitable for home environments. Some users replace the default fan with quieter alternatives, such as the Cooler Master JetFlow, which can also enhance cooling performance.
Performance Analysis and Comparison
Testing and Real-world Performance
In testing, the Antminer S5 consistently outperformed expectations, achieving a hash rate of 1.186 TH/s, surpassing its rated capacity of 1155 GH/s. It demonstrated reliable stability with minimal errors (<1.5%) even after prolonged use in a controlled environment.
Comparison with Similar Miners
- Antminer S3: The S3 produces a hash rate of 478 GH/s at 366 watts, significantly underperforming compared to the S5’s efficiency and output.
- Spondoolies-Tech SP20: Offers 1.1 TH/s but consumes 600 watts, slightly less efficient than the S5.
- Antminer S7: Though more powerful at 4.73 TH/s, the S7 requires 1290 watts, making the S5 a better choice for electricity-sensitive operations.
Firmware and Updates
Importance of Firmware
Firmware updates are vital for enhancing performance, fixing bugs, and adding new features. For the S5, updates have improved hash rates by 3%, enhanced stability, and introduced support for extra nonce features, expanding pool compatibility.
Steps to Update Firmware
- Download the latest firmware from Bitmain’s website.
- Log in to the miner’s control panel and navigate to “System > Upgrade.”
- Upload the downloaded file and initiate the upgrade.
