Taiwan Semiconductor Manufacturing Company (TSMC) has officially commenced mass production at its Nanjing 12-inch wafer fabrication plant, marking a pivotal development in the global semiconductor and cryptocurrency mining industries. The facility, which achieved full-scale output in just 20 months from groundbreaking to shipment, is now producing 16nm-class advanced chips primarily for Bitmain, the world’s leading cryptocurrency mining hardware manufacturer.
This milestone not only highlights TSMC’s operational efficiency but also underscores the growing strategic importance of dedicated ASIC chips in high-performance computing (HPC) and blockchain infrastructure. As demand for efficient mining hardware surges, TSMC’s Nanjing plant has become China's first major production base for 16nm process technology, reinforcing the company's dominance in foundry services.
Strategic Significance of the Nanjing Facility
Nanjing, traditionally known as a historical and cultural hub, has rapidly evolved into a key player in China’s semiconductor ecosystem. Backed by strong government support and strategic investments, the city has attracted industry giants like TSMC and Tsinghua Unigroup, transforming it into a full-fledged semiconductor cluster.

Today, Nanjing hosts a complete semiconductor supply chain—from chip design and fabrication to packaging and testing—creating an integrated ecosystem that supports both domestic needs and global export demands. With China accounting for over half of global semiconductor purchases—$250 billion out of $400 billion in 2017 alone—the localization of advanced manufacturing through facilities like TSMC’s Nanjing plant plays a crucial role in advancing China’s semiconductor self-sufficiency goals.
The rapid deployment of the Nanjing fab reflects TSMC’s agile response to market dynamics. In just 20 months, the facility transitioned from construction to volume production, showcasing one of the fastest ramp-up times in the industry. This speed positions TSMC ahead of competitors in meeting urgent demand from high-growth sectors such as cryptocurrency mining and AI-driven computing.
The Rise of ASIC Chips in Cryptocurrency Mining
Application-Specific Integrated Circuits (ASICs) have become the backbone of modern cryptocurrency mining due to their unmatched efficiency in performing repetitive cryptographic calculations. Unlike general-purpose GPUs, ASICs are optimized specifically for hashing algorithms used in Bitcoin and other proof-of-work blockchains.
Bitmain, a dominant force in the mining hardware market, designs and deploys these specialized chips at scale. Its Antminer series has consistently led the industry in computational power (hash rate) and energy efficiency. With TSMC now supplying 16nm ASIC wafers from Nanjing, Bitmain gains access to cutting-edge process technology that enhances performance while reducing power consumption—a critical factor in maintaining profitability amid fluctuating crypto prices.
TSMC does not disclose specific customer names, but financial disclosures reveal a significant increase in revenue from Greater China clients—from 11% to 19% year-over-year. Given Bitmain’s massive order volume, including an estimated 20,000 wafers per month dedicated solely to 16nm mining chips, this growth trajectory aligns closely with increased demand from mining-focused clients.
High-Performance Computing: A Broader Growth Driver
While cryptocurrency mining grabs headlines, TSMC views HPC as a more sustainable long-term driver of growth. During recent earnings calls, executives emphasized optimism around HPC-related applications, including data centers, artificial intelligence, and deep learning accelerators.
In 2017, HPC accounted for approximately 20% of TSMC’s total revenue. The company projected this figure to rise to 25% in the following year, though analysts believe actual growth could exceed expectations—potentially reaching between 37.5% and 43.75%. This upward revision is fueled by strong demand from both cloud providers and specialized hardware developers leveraging TSMC’s advanced nodes.
Notably, TSMC revealed that quarterly revenue linked to cryptocurrency-related products ranged between $340 million and $530 million—highlighting the segment’s material impact on overall performance. While the company maintains a cautious stance due to market volatility, it continues investing in capacity expansion to meet sustained demand.
Competitive Landscape: TSMC vs. Samsung
TSMC currently holds over 90% of the global market share for mining ASIC production, particularly at advanced nodes like 16nm and below. However, Samsung remains a formidable competitor, having secured partnerships with Chinese miner Baikal and collaborating with Silicon Intellectual Property (SIP) firms like eMemory and Faraday Technology.
Although Samsung previously explored joint production initiatives with TSMC for ASIC mining hardware—an announcement made on January 29—the two remain fierce rivals in the foundry space. With TSMC leading in 7nm and below process technologies, Samsung is aggressively pushing its own 8nm and 5nm nodes to capture market share.
Despite speculation about reduced crypto demand affecting future outlooks, both companies continue expanding their manufacturing capabilities. The competitive tension between them benefits innovators and end-users alike by driving faster technological advancement and improved cost efficiencies.
Bitmain’s Expanding Footprint and Future Outlook
Contrary to rumors in Q1 suggesting Bitmain had slashed orders with TSMC, industry sources confirm that order volumes remain robust. The perceived drop in downstream packaging and substrate orders was merely a temporary shift during the transition of 16nm ASIC production from Taiwan-based fabs to the Nanjing facility.
Bitmain has reportedly secured a dedicated production line at the Nanjing plant capable of manufacturing up to 200,000 twelve-inch wafers per month—a testament to its scale and strategic importance. Additionally, the company continues producing 28nm ASICs and plans new tape-outs soon, indicating ongoing innovation across multiple process nodes.
Founded just four years ago, Bitmain has risen rapidly by focusing exclusively on mining-specific chip design. Its Antminer S1 marked the break-even point for initial investment, and subsequent models capitalized on Bitcoin’s bull run to propel the company into China’s top five fabless IC design firms by revenue.

Market Resilience Despite Volatility
Even after Bitcoin’s sharp correction in recent years, mining activity shows no signs of slowing down. Major Ethereum and Bitcoin mining farms—especially those based in China—continue upgrading equipment rather than scaling back operations. Bitmain itself plans to release new-generation miners in the second half of the year, signaling confidence in long-term demand.
While Morgan Stanley has noted declining mining profitability due to rising difficulty and electricity costs, reinvestment in efficient hardware remains a top priority. This trend ensures continued demand for advanced semiconductors from manufacturers like TSMC.
Though TSMC adjusted its 2018 revenue forecast downward—from an initial range of 10–15% growth to around 10%—due to uncertainties in crypto demand, the underlying fundamentals remain strong. The Nanjing plant’s success enables faster recovery of its NT$90 billion investment while solidifying TSMC’s leadership in global foundry services.
