is An application-specific integrated circuit (ASIC) is an integrated circuit (IC) chip customized for a particular use, rather than intended for general-purpose use. For example, a chip designed to run in a digital voice recorder or a high-efficiency Bitcoin miner is an ASIC. Application-specific standard product (ASSP) chips are intermediate between ASICs and industry-standard integrated circuits like the 7400 series or the 4000 series. ASIC chips are typically fabricated using metal-oxide-semiconductor (MOS) technology, as MOS integrated circuit chips.
MicroBT is a manufacturer of cryptocurrency, blockchain, and artificial intelligence computing hardware, and also operates the world’s largest and second-largest Bitcoin mining pools according to the companies website.
As feature sizes for have shrunk and design tools improved over the years, the maximum complexity (and hence functionality) possible in an ASIC has grown from 5,000 logic gates to over 100 million. Modern ASICs often include entire microprocessors, memory blocks including ROM, RAM, EEPROM, flash memory, and other large building blocks. Such an ASIC is often termed an SoC (system-on-chip). Designers of digital ASICs often use a hardware description language (HDL), such as Verilog or VHDL, to describe the functionality of ASICs.
utilizes Field-programmable gate arrays (FPGA) are the modern-day technology for building a breadboard or prototype from standard parts[vague]; programmable logic blocks and programmable interconnects allow the same FPGA to be used in many different applications. For smaller designs or lower production volumes, FPGAs may be more cost-effective than an ASIC design, even in production. The non-recurring engineering (NRE) cost of an ASIC can run into the millions of dollars. Therefore, device manufacturers typically prefer FPGAs for prototyping and devices with low production volume and ASICs for very large production volumes where NRE costs can be amortized across many devices.
Early ASICs used gate array technology. By 1967, Ferrari and InterDesign were manufacturing early bipolar gate arrays. In 1967, Fairchild Semiconductor introduced the Micro matrix family of bipolar diode–transistor logic and transistor-transistor logic arrays.
Complementary metal-oxide-semiconductor (CMOS) technology opened the door to the broad commercialization of gate arrays. The first CMOS gate arrays were developed by Robert Lipp in 1974 for International Microcircuits, Inc.
utilizes a Metal-oxide-semiconductor standard cell technology was introduced by Fairchild and Motorola, under the trade names Micromosaic and Polycell, in the 1970s. This technology was later successfully commercialized by VLSI Technology and LSI Logic.
A successful commercial application of gate array circuitry was found in the low-end 8-bit ZX81 and ZX Spectrum personal computers, introduced in 1981 and 1982. These were used by Sinclair Research essentially as a low-cost I/O solution aimed at handling the computer’s graphics.
Customization occurred by varying a metal interconnect mask. Gate arrays had complexities of up to a few thousand gates; this is now called mid-scale integration. Later versions became more generalized, with different base dies customized by both metal and polysilicon layers. Some base dies also include random-access memory (RAM) elements.

A Stalwart in the World of Cryptocurrency Mining
The landscape of cryptocurrency mining is one of constant evolution, demanding increasingly powerful and efficient hardware to remain competitive. In this dynamic environment, Bitmain has consistently positioned itself as a leading manufacturer of Application-Specific Integrated Circuit (ASIC) miners. Their Antminer series has become synonymous with Bitcoin mining, and among its notable iterations stands the Bitmain Antminer S19 86Th Bitcoin Miner. Launched as part of the S19 generation, this machine represented a significant leap forward in computational power and energy efficiency at the time of its release, solidifying Bitmain’s dominance and providing miners with a formidable tool for securing the Bitcoin network and potentially generating profit. Even years after its debut, understanding the capabilities and context of the Bitmain Antminer S19 86Th Bitcoin Miner remains crucial for anyone involved in or considering entering the SHA-256 mining sphere. ASIC miners are the bedrock of modern Bitcoin mining. Unlike general-purpose hardware like CPUs or GPUs, ASICs are designed from the ground up for a single task: performing the specific hashing calculations required by a particular cryptocurrency’s algorithm. For Bitcoin, this algorithm is SHA-256. The Bitmain Antminer S19 86Th Bitcoin Miner is a purpose-built SHA-256 powerhouse, engineered to execute these calculations at incredible speeds while optimizing for energy consumption. Its introduction marked a continuation of the technological arms race in mining hardware, pushing the boundaries of what was possible and setting new benchmarks for performance within the industry.The Evolution of Antminers: Release and Advancement
Launching the S19 Series: A New Era in Mining
The Bitmain Antminer S19 series, including the Bitmain Antminer S19 86Th Bitcoin Miner variant, made its debut in the spring of 2020. This launch was highly anticipated within the mining community. It arrived at a critical juncture, succeeding the Antminer S17 generation and preceding a significant surge in Bitcoin’s price later that year and into 2021. The timing meant that early adopters of the S19 series were well-positioned to capitalize on the burgeoning market conditions. The release represented Bitmain’s commitment to leveraging cutting-edge semiconductor technology to deliver substantial performance gains, ensuring their hardware remained at the forefront of the competitive mining sector. The Bitmain Antminer S19 86Th Bitcoin Miner was one of the initial models available within this groundbreaking series.Significant Upgrades from Predecessors (Like the S17)
The Antminer S19 series was not merely an incremental update; it was a significant technological leap compared to its predecessors, primarily the Antminer S17 and S17+ models. While the S17 series had offered impressive hash rates for its time, it was plagued by reports of reliability issues, particularly concerning overheating and hardware failures related to power delivery and heat sink mounting. Bitmain addressed these concerns head-on with the S19 generation. One of the most crucial upgrades was the improvement in power efficiency. The Bitmain Antminer S19 86Th Bitcoin Miner, along with its series counterparts, utilized a new generation of custom-designed 7nm ASIC chips. These chips allowed for a higher density of transistors, enabling more computational power within a similar thermal and energy envelope. This resulted in a dramatically better Joules per Terahash (J/TH) rating compared to the S17 series. Where S17 models hovered around 40-50 J/TH or higher, the S19 series pushed efficiency into the 30s J/TH range, a substantial improvement. The Bitmain Antminer S19 86Th Bitcoin Miner, specifically, aimed for an efficiency around 37.8 J/TH, making it significantly more cost-effective to run in terms of electricity consumption per unit of hashing power. Beyond raw efficiency and hash rate (where the S19 series offered models ranging from 82Th up to 110Th, surpassing the typical 50-60Th range of the S17+), Bitmain also implemented design improvements aimed at enhancing stability and longevity. This included refined thermal management systems with potentially improved fan configurations and heat sink designs, learning from the challenges faced by the S17 generation. The power delivery system was also likely revisited to ensure more stable operation under the demanding continuous load required for mining. Consequently, the Bitmain Antminer S19 86Th Bitcoin Miner and its siblings were perceived as more robust and reliable machines, crucial factors for large-scale mining operations where downtime translates directly into lost revenue.Deep Dive: Understanding the Bitmain Antminer S19 86Th Bitcoin Miner
Core Functionality: Mining Bitcoin with SHA-256
At its heart, the Bitmain Antminer S19 86Th Bitcoin Miner is designed to solve complex mathematical problems dictated by the Bitcoin protocol. Bitcoin uses the SHA-256 (Secure Hash Algorithm 256-bit) hashing function. Miners like the S19 86Th repeatedly perform hashing operations on transaction data combined with a random number (nonce) until they find a hash output that meets a specific target difficulty set by the network. This process, known as Proof-of-Work (PoW), serves two main purposes: it validates and adds new blocks of transactions to the Bitcoin blockchain, and it secures the network against fraudulent activities. The miner who successfully finds the valid hash is rewarded with newly minted bitcoins (the block reward) and transaction fees from the included transactions. The Bitmain Antminer S19 86Th Bitcoin Miner is specifically engineered to perform these SHA-256 computations at an extremely high rate (its hash rate).The Importance of Application-Specific Integrated Circuits (ASICs)
The dominance of ASICs like the Bitmain Antminer S19 86Th Bitcoin Miner in Bitcoin mining cannot be overstated. In the early days of Bitcoin, mining could be done using standard computer CPUs (Central Processing Units). As the network grew and the mining difficulty increased, miners shifted to GPUs (Graphics Processing Units), which offered significantly better parallel processing capabilities. However, the advent of ASICs changed the game entirely. An ASIC is designed for one specific task, stripping away all general-purpose computing functions. This singular focus allows for orders of magnitude greater hashing performance and energy efficiency compared to CPUs or GPUs when mining the specific algorithm the ASIC was designed for (in this case, SHA-256). The Bitmain Antminer S19 86Th Bitcoin Miner exemplifies this specialization, making GPU or CPU mining for Bitcoin economically infeasible today. Investing in a dedicated ASIC miner became, and remains, essential for serious Bitcoin mining endeavors.Key Specifications of the Bitmain Antminer S19 86Th Bitcoin Miner and Their Significance
Understanding the technical specifications of the Bitmain Antminer S19 86Th Bitcoin Miner is crucial for evaluating its performance, potential profitability, and operational requirements. Each specification plays a vital role in the mining process.Hash Rate: 86 TH/s ± 3%
This is perhaps the most commonly cited performance metric. Hash rate measures the number of SHA-256 calculations the miner can perform per second. One Terahash (TH/s) equals one trillion hashes per second. Therefore, the Bitmain Antminer S19 86Th Bitcoin Miner can perform approximately 86 trillion hash calculations every second. Importance: A higher hash rate directly increases the miner’s probability of finding the next block on the Bitcoin network before competitors. In a mining pool context (where most miners operate), a higher hash rate translates to a larger share of the pool’s earnings. While 86 TH/s was competitive upon release in 2020, it’s important to note that the total network hash rate has grown significantly since then, meaning this hash rate yields a smaller fraction of the total network power today. Nevertheless, it represents substantial computational power dedicated solely to mining Bitcoin.Power Consumption: 3250W ± 5%
This figure indicates the amount of electrical power the miner draws from the wall while operating. It’s typically measured in Watts (W). The Bitmain Antminer S19 86Th Bitcoin Miner consumes around 3250 Watts, which is comparable to several high-power household appliances running simultaneously (like multiple electric kettles or a powerful space heater). Importance: Power consumption is a critical factor determining the operational cost and, therefore, the profitability of mining. Electricity is usually the single largest ongoing expense for miners. A 3250W consumption rate means the miner uses 3.25 kilowatt-hours (kWh) of energy for every hour it runs. Multiplying this by the local electricity price per kWh gives the hourly running cost. Miners must ensure their electrical infrastructure (wiring, breakers, outlets) can safely handle this continuous high load, typically requiring a 220-240V circuit for optimal efficiency and stability. Lower power consumption, for a given hash rate, leads to higher profits.Power Efficiency: Approximately 37.8 J/TH ± 5%
Power efficiency is arguably the most critical specification for long-term mining viability. It measures how much energy is consumed to perform a certain amount of hashing work, expressed in Joules per Terahash (J/TH). It’s calculated by dividing the power consumption (in Watts, which is Joules per second) by the hash rate (in Terahashes per second). For the Bitmain Antminer S19 86Th Bitcoin Miner: 3250 W / 86 TH/s ≈ 37.8 J/TH. Importance: A lower J/TH figure indicates better efficiency – the miner uses less electricity to achieve each Terahash of computational power. This directly impacts profitability. A more efficient miner can remain profitable even when Bitcoin prices are low or electricity costs are high. The ~37.8 J/TH efficiency of the Bitmain Antminer S19 86Th Bitcoin Miner was a major selling point in 2020, representing a significant improvement over the S17 generation (often 45-55 J/TH or higher). As newer miners push efficiency even lower (sub-30 J/TH, even sub-20 J/TH for the latest models), the efficiency metric becomes paramount for comparing different hardware generations.Algorithm: SHA-256
This specifies the cryptographic hashing algorithm the miner is designed to execute. Importance: The Bitmain Antminer S19 86Th Bitcoin Miner is hardwired to mine SHA-256. This means it can mine Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin SV (BSV), and other cryptocurrencies that use the same algorithm. It cannot be used to mine cryptocurrencies based on different algorithms like Scrypt (Litecoin) or Ethash (Ethereum Classic). This specialization is key to its high performance on Bitcoin but limits its flexibility.Operating Environment: Temperature and Humidity
Manufacturers specify an optimal range for operation, typically around 5°C to 40°C (41°F to 104°F) ambient temperature and low to moderate humidity (e.g., 5% to 95% non-condensing). The Bitmain Antminer S19 86Th Bitcoin Miner generates significant heat due to its high power consumption. Importance: Maintaining the correct operating environment is crucial for performance, stability, and longevity. Overheating can cause the miner to throttle its performance, shut down unexpectedly, or even suffer permanent damage to the sensitive ASIC chips. Adequate ventilation and cooling are essential. This involves ensuring strong airflow (the built-in fans are powerful and loud) and potentially using dedicated cooling solutions in larger farms. Humidity control prevents condensation and corrosion. Proper environmental management protects the investment in the Bitmain Antminer S19 86Th Bitcoin Miner.Physical Dimensions and Weight
The S19 series generally has dimensions in the range of 400mm x 195mm x 290mm and weighs around 14-15 kg (approx. 15.7 x 7.7 x 11.4 inches, 31-33 lbs). Specifics might vary slightly. Importance: These physical attributes are practical considerations for miners. They determine space requirements for storage and operation, racking compatibility in larger facilities, and handling logistics. The weight requires sturdy shelving, and the dimensions influence airflow planning around the units.Network Connection: Ethernet
The Bitmain Antminer S19 86Th Bitcoin Miner connects to the internet via a standard Ethernet port (RJ45). Importance: A stable network connection is mandatory for mining. The miner needs to communicate with a mining pool server to receive work assignments (block templates) and submit completed work (potential block solutions or shares). It also needs to stay synchronized with the broader Bitcoin network state. Reliability here is key; network interruptions mean lost mining time.Setting Up and Operating the Bitmain Antminer S19 86Th Bitcoin Miner
Installation Considerations
Setting up a Bitmain Antminer S19 86Th Bitcoin Miner requires careful attention to its power and environmental needs. Firstly, the power supply unit (PSU) is critical. While some miners might be sold with an integrated PSU, often Bitmain’s recommended APW12 PSU (or an equivalent) is required. This PSU is designed to handle the high, continuous power draw. Crucially, operating the miner on a 220V-240V electrical circuit is highly recommended, if not required, for optimal efficiency and stability compared to standard 110V-120V circuits common in North American households. This often necessitates dedicated wiring installed by a qualified electrician. Secondly, network setup involves connecting the miner via an Ethernet cable to a router or switch that has internet access. Once powered on, the miner obtains an IP address (usually via DHCP), which is needed to access its configuration interface.Configuration and Mining Pools
Accessing the Bitmain Antminer S19 86Th Bitcoin Miner’s configuration is typically done through a web browser by navigating to the miner’s IP address on the local network. Bitmain provides tools or methods (like scanning the network) to find this IP address. The web interface allows users to configure essential settings, most importantly the mining pool details. Solo mining (trying to find blocks alone) is statistically infeasible for all but the largest operations due to the immense total network hash rate. Therefore, virtually all miners connect to a mining pool. In the configuration panel, the user inputs the pool’s stratum address, their username or wallet address for that pool, and a worker name to identify the specific miner. Once configured and saved, the Bitmain Antminer S19 86Th Bitcoin Miner will begin requesting work from the pool and hashing.Maintenance and Longevity
To ensure the Bitmain Antminer S19 86Th Bitcoin Miner operates efficiently and lasts as long as possible, regular maintenance is essential. The high-speed fans draw in significant amounts of air, and with it, dust and debris. Regularly cleaning dust filters (if present) and blowing compressed air through the heat sinks and fans is crucial to prevent dust buildup, which can impede airflow and cause overheating. Monitoring the operating temperatures (chip temperatures, inlet/outlet air temperatures) via the web interface is vital. Consistently high temperatures might indicate inadequate cooling or excessive dust. Checking that all fans are spinning correctly is also important. Proactive maintenance helps prevent performance degradation and hardware failures, maximizing the return on investment for the Bitmain Antminer S19 86Th Bitcoin Miner.The Bitmain Antminer S19 86Th in the Modern Mining Landscape (2025)
Relevance and Profitability Today
As of early 2025, the Bitcoin mining landscape has continued its relentless march towards greater efficiency. Bitmain itself has released more advanced models, including the S19 XP, S19 Pro+ Hydro, and the S21 series, which boast significantly better power efficiency ratings (often well below 25 J/TH). Other manufacturers like MicroBT (Whatsminer) also offer highly competitive machines. Compared to these state-of-the-art miners, the Bitmain Antminer S19 86Th Bitcoin Miner, with its efficiency around 37.8 J/TH, is less competitive. Its profitability today is highly contingent on several factors: 1. Electricity Cost: This is paramount. In regions with very low electricity prices (e.g., below $0.05-$0.07 per kWh), the Bitmain Antminer S19 86Th Bitcoin Miner might still generate a positive cash flow. In areas with moderate to high electricity costs, it is likely unprofitable or marginally profitable, especially after events like the Bitcoin Halving (which reduces block rewards). 2. Bitcoin Price: Higher Bitcoin prices increase the value of the rewards earned, potentially making less efficient miners profitable again. 3. Network Difficulty: As more efficient hardware comes online, the total network hash rate increases, leading to upward adjustments in mining difficulty. This makes it harder for older hardware like the Bitmain Antminer S19 86Th Bitcoin Miner to earn the same amount of Bitcoin over time. Therefore, while it was a top-tier machine in 2020, the Bitmain Antminer S19 86Th Bitcoin Miner is now considered a mid-to-lower tier option in terms of efficiency. Potential buyers or operators must use up-to-date mining profitability calculators, inputting their specific electricity costs and current network conditions, to determine its viability.Secondary Market and Use Cases
Due to the influx of newer, more efficient models, the Bitmain Antminer S19 86Th Bitcoin Miner is readily available on the secondary market, often at prices significantly lower than its original cost. This can make it an attractive option for certain use cases. Hobbyist miners or those looking to learn about ASIC mining operations might find it a more accessible entry point compared to the latest, much more expensive hardware. Smaller operations in locations with exceptionally cheap or subsidized power might still find value in running these units. However, buyers on the secondary market should exercise caution, verifying the miner’s condition and operational history, as used ASICs can sometimes have underlying issues from previous demanding usage.Final Thoughts
Legacy of the Antminer S19 86Th
The Bitmain Antminer S19 86Th Bitcoin Miner holds a significant place in the history of Bitcoin mining hardware. As part of the S19 series launched in 2020, it represented a major step forward in both hash rate and, crucially, power efficiency compared to its S17 predecessors. Its arrival, powered by advanced 7nm chip technology, offered miners substantially improved performance (86 TH/s) and better energy economics (around 37.8 J/TH), addressing reliability concerns and setting new benchmarks for the industry at the time. While the relentless pace of technological advancement means the Bitmain Antminer S19 86Th Bitcoin Miner is no longer at the cutting edge of efficiency in 2025, it remains a testament to Bitmain’s engineering capabilities during its era. Its viability today hinges heavily on operational factors, primarily electricity cost. For those with access to very cheap power, or for individuals entering the mining space on a budget via the secondary market, the Bitmain Antminer S19 86Th Bitcoin Miner might still hold relevance. However, a thorough profitability analysis based on current Bitcoin price, network difficulty, and precise energy expenses is absolutely essential before investing in or operating this machine. It stands as a powerful reminder of the dynamic and competitive nature of the Bitcoin mining ecosystem.Ready to Buy
