Bitmain's latest mining machine S19 announced the highest energy efficiency ratio in history, reaching 29.5J/TH

Wu said blockchain learned that on the afternoon of the 27th, Bitmain announced the S19 mining machine equipped with the latest 7nm chip. The S19 has a single-machine computing power of up to 110TH/s and an energy efficiency ratio of 29.5J/TH±5%, making it the most energy-efficient Bitcoin mining machine in the world. Bitmain has not yet announced the price of this product.

Wu Blockchain believes that the launch of this mining machine and the successful testing of the 5nm chip reveal that after the withdrawal of Zhan Ketuan, Bitmain still maintains an absolute leading advantage in technology. The sales area led by Wu Jihan also reversed the downward trend in 2019.

The S19 series currently launched has two products:

Bitmain said that the S19 series mining machines are equipped with Bitmain's new generation of customized chips, with an energy efficiency ratio as low as 23J/TH. Through revolutionary circuit architecture adjustments, the energy efficiency ratio is pushed to the extreme.

In November 2019, Wu Blockchain exclusively learned that Bitmain's S19 chip had been sent to TSMC for wafer verification and would be returned for wafer verification soon. The S19 will use TSMC's 7nm technology, and the S19PRO performance index can reach up to 30 watts per terabyte.

At present, the S19 chip has reached 23J/TH, far exceeding the original target of 30, indicating that with the help of TSMC, the technology has made greater breakthroughs. In fact, the S19 could have been launched earlier, but Bitmain still has S17 inventory to clear, so the launch time has been delayed.

Recently, major mining machine manufacturers have successively released the latest high-computing power products. In early December, Shenma released the latest mining machine M30S equipped with Samsung 8nm chip, with power consumption ratio of 38 J/T and total computing power of 88T. In early January, Innosilicon announced that it will soon launch a new generation of Bitcoin mining machine T4+75T, with a computing power of 75T H/s, energy efficiency ratio of 44J/T, an expected service life of 3 years, and a repair rate of less than 2%.

In addition, in December, Bitmain's 5nm test chip based on TSMC was successfully returned, which should be the world's first successfully tested 5nm chip.

Bitmain's advantage lies in its exclusive monopoly on TSMC's 7nm process, while Canaan, Xindong, Shenma, etc. are all Samsung's customers. TSMC is more advanced in process technology, so Bitmain can achieve better energy efficiency. But the problem also lies in TSMC's products are too excellent, and it is more difficult and expensive for Bitmain to obtain chip production capacity.

Although the major mining machine manufacturers are facing some difficulties due to the epidemic, the only decisive factor for mining machine sales is the price of Bitcoin. Recently, the price of Bitcoin has fallen below $9,000, which has increased the uncertainty of the halving market and will also affect the sales of mining machines to a certain extent.
