In February this year, bitland took the lead in releasing the second-generation self-developed 7Nm chip bm1397 in the industry, and announced that it will be carried in the new ant mining machine of the next generation. It is reported that bm1397 adopts the world's leading TSMC FinFET technology, with higher chip integration and better heat dissipation effect. A single chip integrates more than 1 billion transistors. Thanks to the continuous strengthening of the second generation 7Nm chip in circuit structure and low-power technology, the performance of S17 Pro has been significantly improved. In addition, S17 Pro adopts new heat dissipation technology and global optimization customization scheme, fully considers factors such as chip architecture and overall economy, and realizes global optimization by strengthening the core part and taking into account the optimization of other modules.
