The cryptocurrency mining industry is experiencing a significant rebound, reigniting demand for advanced semiconductor manufacturing. At the center of this resurgence is Taiwan Semiconductor Manufacturing Company (TSMC), which is reportedly expanding its 7-nanometer (7nm) production capacity to fulfill urgent orders from leading mining hardware manufacturers — most notably Bitmain. Simultaneously, MicroBT’s latest 5nm-designed Whatsminer series has entered the spotlight, signaling a new era of high-efficiency, next-generation mining rigs.
This renewed momentum reflects broader trends in both blockchain technology adoption and advancements in chip design. As Bitcoin prices stabilize and mining profitability improves, companies are racing to deploy more powerful and energy-efficient application-specific integrated circuits (ASICs). TSMC, the world’s most advanced foundry, is once again at the heart of this technological arms race.

TSMC Ramps Up 7nm Output Amid Soaring Demand
Supply chain sources confirm that TSMC has received emergency orders from Bitmain for additional 7nm wafers, prompting the company to increase monthly output by 10,000 12-inch wafers starting in November. To support this expansion, senior TSMC executives recently traveled to Japan to secure critical semiconductor equipment needed for accelerated production.
While TSMC does not comment on individual client relationships, industry insiders note that the surge in demand stems from both cryptocurrency mining and robust 5G infrastructure deployment worldwide. The influx of cash-paying clients like Bitmain has given TSMC greater financial flexibility, potentially pushing its annual capital expenditure above $11 billion — a figure that will be officially disclosed during its October earnings call.
The 7nm node remains one of TSMC’s most strategically important technologies. It powers not only high-performance computing chips and next-gen mobile processors but also dominates the ASIC mining market. With Apple, Qualcomm, and Huawei all relying heavily on 7nm for flagship products, capacity was already tight — and now, with mining demand returning, utilization rates are nearing full saturation.
Bitmain Drives Market With High-Performance ASICs
Bitmain, the dominant player in Bitcoin mining hardware, continues to push performance boundaries. Its Antminer S19 series, built on TSMC’s 7nm process, includes models such as the Antminer S19 XP (140 TH/s) and S19 Pro+ Hyd (up to 198 TH/s). Most notably, the upcoming Antminer S19 XP Hyd, a water-cooled unit, promises an industry-leading hash rate of 255 terahashes per second (TH/s) — a benchmark that sets a new standard for computational power in decentralized networks.
These machines are not just faster; they’re also more energy-efficient, a crucial factor as environmental, social, and governance (ESG) concerns grow within the crypto space. Efficient mining reduces operational costs and aligns with global sustainability trends — making cutting-edge chips more valuable than ever.
MicroBT Enters the 5nm Era With Whatsminer M50 Series
While Bitmain leads in raw performance, MicroBT (also known as MicroBT) is rapidly closing the gap with its Whatsminer M50 series, unveiled at the Bitcoin 22 conference in Miami. Featuring fully custom-designed ASIC chips manufactured using an advanced 5nm process, the M50 lineup represents a major leap forward in efficiency and scalability.
The top-tier model, Whatsminer M50S, delivers 126 TH/s with a power efficiency of 26 joules per terahash (J/TH) while consuming 3,276 watts. This places it among the most efficient miners currently available. Even more impressive is MicroBT’s hint at a future water-cooled model capable of 240 TH/s with an efficiency of 29 J/TH — further narrowing the performance gap with Bitmain.
Although the rumored M53 model hasn’t yet appeared on MicroBT’s official site, the company confirms it is preparing for mass shipments in Q3 2022. Current models — including the M50 (114 TH/s) priced at $8,857.80 and M50S at $10,924.20 — are already available and showing strong returns based on current Bitcoin valuations.
MicroBT also emphasizes its global supply chain readiness, stating it can produce and ship over 30,000 units per month from its Southeast Asia facilities. The firm is actively expanding support into emerging mining regions such as North America.
“The M50 Series will help customers enter the 2X J/T mining era and maintain endless power for ESG-friendly mining,” said Chen Jianbing, COO of MicroBT.

The Return of Mining Profits and Technological Competition
After a prolonged downturn following Bitcoin’s 2021 crash — which forced TSMC to revise its outlook multiple times — the mining ecosystem is regaining stability. Rising Bitcoin prices, improved network difficulty adjustments, and access to low-cost energy in new mining hubs have collectively restored profitability for many operators.
This recovery has triggered a new wave of innovation. The shift from 7nm to 5nm chip designs marks a pivotal moment: smaller transistors mean higher performance per watt, longer hardware lifespans, and lower total cost of ownership. For miners operating at scale, even a few joules saved per terahash can translate into millions in annual savings.
Moreover, competition between Bitmain and MicroBT is driving faster product cycles and better engineering. Where once there was little differentiation between models, today’s market sees rapid iteration — with each new release pushing efficiency and performance metrics higher.
Frequently Asked Questions (FAQ)
