The cryptocurrency mining landscape has entered a pivotal phase, with Bitmain’s recent release of its next-generation 7nm ASIC miners—the Antminer S15 and T15—marking a crucial turning point. Within just 30 minutes of going live on November 8, both models sold out on Bitmain’s official store, signaling strong market demand and renewed confidence in the mining hardware giant.
This launch arrives at a critical moment for Bitmain, which has faced mounting pressure over delays in product innovation, challenges within the Bitcoin Cash (BCH) ecosystem, and a turbulent path toward an initial public offering (IPO). As competition intensifies from rivals like Canaan Creative and MicroBT, the success of these new miners could determine whether Bitmain reclaims its dominant position or cedes ground in the evolving mining arms race.

Performance Breakdown: S15 vs. T15 vs. Competitors
Bitmain’s latest offerings showcase significant improvements in energy efficiency and thermal management, leveraging cutting-edge 7nm chip technology. Each 7nm chip integrates one billion transistors and employs Exposed Die packaging instead of traditional overmolding, enhancing heat dissipation by 3%–5%. Combined with a parallel fan design and integrated power supply unit (PSU), the new miners offer better performance per watt than previous generations.
Antminer S15 (28T)
- Standard Mode: 28 TH/s at 57 J/T (1596W)
- Low-Power Mode: 17 TH/s at 50 J/T (850W)
Antminer T15 (23T)
- Standard Mode: 23 TH/s at 67 J/T (1541W)
- Low-Power Mode: 20 TH/s at 60 J/T (1200W)
These specs place the S15 and T15 ahead of many existing models in terms of energy efficiency, particularly when compared to older 16nm designs. However, they face stiff competition:
- Canaan’s Avalon A921: 20 TH/s at 85 W/T (1700W), priced at $5,400
- Avalon A911 (Low Power): 18 TH/s at 80 W/T (1440W)
- MicroBT’s Whatsminer M10: 33 TH/s at 65 W/T (2145W), priced at $11,880
While the Whatsminer M10 leads in raw hashing power—surpassing the 30 TH/s threshold—Bitmain’s new models excel in energy efficiency, especially in low-power configurations. This trade-off between performance and power consumption is increasingly vital as mining profitability hinges on electricity costs and network difficulty adjustments.
Bitmain’s pricing strategy reflects this balance:
- S15: $11,400
- T15: $7,000
Given current Bitcoin network conditions and average electricity rates, both models appear competitive for large-scale mining operations focused on long-term sustainability.
Bitmain’s Make-or-Break Moment
The launch of the S15 and T15 isn’t just another product update—it’s a strategic response to a series of existential challenges.
For over two years, Bitmain relied heavily on its aging Antminer S9, launched in June 2016. Despite being sold at discounted prices (around $4,850), the S9’s relevance has waned as newer, more efficient models enter the market. Critics have questioned Bitmain’s innovation pipeline, especially as Canaan and MicroBT unveiled advanced miners during mid-to-late 2024.
With rivals gaining momentum, Bitmain needed a strong comeback. The rapid sellout suggests market trust remains intact—but sustained success depends on timely delivery and real-world reliability. Initial shipments are scheduled to begin December 1, and any delays could erode confidence.
The BCH Factor: A Divisive Bet
Beyond hardware, Bitmain is deeply invested in the future of Bitcoin Cash. With over one million BCH tokens held on its balance sheet, the company has aligned itself with the Bitcoin ABC development team ahead of the November 15 network fork.
Opposing factions—led by Craig Wright’s nChain versus WU Jihan’s supported group—have created a high-stakes showdown. While early hash rate data suggests dominance by the ABC side (~51.78% vs. ~3.25%), a prolonged split risks fragmenting the network and undermining long-term value.
Bitmain’s aggressive stance may secure short-term control but could also alienate parts of the community. Centralization of mining power raises concerns about decentralization—a core tenet of blockchain networks.

IPO Struggles and Financial Transparency
Bitmain’s financial health has also drawn scrutiny. Its draft IPO filings reveal that 94.5% of revenue in early 2024 came from miner sales, with the S9 alone contributing 67%. This heavy reliance on legacy products underscores vulnerability.
Competitors like Canaan are advancing toward public listing, raising capital to fund R&D and production. Delays, funding controversies, and halted IPO plans have cast shadows over Bitmain’s transparency—even if officially denied.
If the S15 and T15 fail to gain traction, revenue could plummet, threatening R&D budgets and future competitiveness.
The Evolution of Mining Power: From Pioneers to Giants
Mining history shows that technological leaps redefine industry leadership.
- In 2013, Zhang “Pumpkin” Nanqiang introduced the first ASIC miner, Avalon, but limited output allowed rival “Friedcat” to dominate briefly with crowd-funded ASICs.
- By mid-2013, Friedcat controlled nearly one-third of Bitcoin’s hash rate, sparking fears of a 51% attack—until technical setbacks led to its downfall.
- That same year, Wu Jihan entered the scene, later co-founding Bitmain with Zhan Ketuan. Their Antminer S1 became a commercial hit due to superior efficiency.
- In 2014, despite bear market conditions, Bitmain launched the 28nm S5 miner—just before the 2015 bull run—cementing its market leadership.
- Under Yang Zuoxing’s engineering leadership (before his departure to found MicroBT), Bitmain advanced into the 16nm era with S7 and S9 models.
Now, with MicroBT pushing performance boundaries and Canaan pioneering 7nm adoption via Avalon A9 series, Bitmain must prove it can innovate at pace.
FAQs: Your Key Questions Answered
Q: Are the S15 and T15 truly better than previous models?
A: Yes. The shift to 7nm chips improves transistor density and thermal efficiency. While raw power doesn’t exceed all competitors, energy efficiency—especially in low-power mode—is significantly better than older models like the S9.
Q: Why did the miners sell out so quickly?
A: High demand from institutional miners stocking up before potential halving events or regulatory changes. Limited initial supply also contributed to rapid depletion.
Q: Is Bitmain still the leader in mining hardware?
A: It remains a top contender. While MicroBT leads in peak performance and Canaan was first with 7nm, Bitmain’s brand reputation, distribution network, and proven track record maintain strong market influence.
Q: When will customers receive their orders?
A: Shipments are expected to start December 1. Exact delivery times depend on order volume and logistics.
Q: How does energy efficiency impact mining profitability?
A: Lower joules per terahash (J/TH) mean less electricity consumed per unit of work—directly increasing net profit margins, especially in regions with high power costs.
Q: Could another mining company overtake Bitmain?
A: Yes—especially if innovation slows. MicroBT and Canaan are investing heavily in R&D. Market leadership now depends on consistent product cycles and reliability.
