The competition in the Bitcoin mining rig manufacturing sector is heating up. Chinese producer Microbt has announced the launch of its next-generation Whatsminer series—the M30S++ and M30S+—with the flagship model delivering a hashrate of 112 TH/s and a power efficiency of just 31 J/TH. This announcement comes hot on the heels of Bitmain's February reveal of two miners rated between 95 TH/s and 110 TH/s, marking a new chapter in the ASIC arms race.
Next-Gen Mining Rigs: M30S++ and M30S+
According to the official specifications, the M30S++ peaks at 112 TH/s with a power consumption of approximately 3,472 watts, yielding an efficiency of 31 J/TH. The second model, the M30S+, offers 100 TH/s at 34 J/TH. Both units leverage Microbt's proprietary advanced ASIC chip design, aimed at providing miners with higher hashrates and lower electricity costs. Notably, Microbt's COO Chen Jianbing stated that the company will extend warranty coverage to a full year, up from the previous 180-day period, a move designed to strengthen customer trust amid fierce competition.
Pricing is set at $2,800 for the M30S+ and $3,900 for the M30S++. Compared to Bitmain's S19 Pro (110 TH/s, 29.5 J/TH, priced around $3,200–$3,500), Microbt's flagship is slightly more expensive but offers 2 TH/s more hashrate, though at marginally higher power consumption. Miners will need to evaluate their specific electricity costs and deployment scale to determine the best fit.
Direct Competition with Bitmain’s S19 Pro
Microbt's latest release is clearly targeting Bitmain's Antminer S19 series launched earlier this year. The S19 Pro delivers 110 TH/s at 29.5 J/TH, while the standard S19 offers 95 TH/s at 34.5 J/TH. The M30S++ edges ahead in raw hashrate but falls slightly behind in efficiency. However, Microbt's achievement of 31 J/TH places it among the industry's elite. This generation of products will be judged not only on peak performance but also on chip design capabilities and supply chain reliability.
Founded in 2017 by Yang Zuoxing—a former Bitmain engineer who led the development of the popular Antminer S7 and S9 models—Microbt quickly gained traction with its Whatsminer line. By 2017, the company had sold close to 400,000 units of the M1 and M3 miners, which at the time powered an estimated 10% of the Bitcoin network's total hashrate. The M30 series represents Microbt's full-throttle effort to claim a leading position in the next era of mining hardware.
Delivery Uncertainty Remains
While Microbt has set a shipping window of June 1–30, the ongoing COVID-19 pandemic continues to disrupt global supply chains. Mining operations such as Riot Blockchain and Hut8 have reported significant shipment delays, hurting their business models. Chinese ASIC manufacturers—Microbt, Bitmain, and Canaan—all face logistics and component shortages, casting doubt on whether the M30 series will arrive on time. Miners placing pre-orders must factor in these risks when planning their fleet upgrades.
Overall, Microbt's M30S++ and M30S+ push the performance envelope further, offering miners efficient new options. As competition intensifies post-halving, the speed and cost-effectiveness of deploying next-generation hardware will directly impact profitability. The industry will closely watch Microbt's production ramp-up and actual delivery performance in the coming months.
