In this regard, Xiaomi CEO Lei Jun released the Weibo and answered the most concerned questions of rice noodles. When asked if he was still making chips, Lei Jun said that it was really because of great difficulties, but the plan was still going on. I'll let you know if there is any new progress.
Lei Jun also said that due to the difficulty in mass production, the mass production of MIX Alpha has been abandoned. In 20 17, Xiaomi released the surging S 1, eight nuclear 64-bit processor, 28nm technology, 2.2GHz quad-core Mali T860 graphics processor, and also released the first mobile phone Xiaomi 5C equipped with surging S 1 chip.
As for the MIX Alpha released by Xiaomi before, Lei Jun said that this is a pre-research project and has successfully completed the pre-research goal. Later, due to the difficulty in mass production, we finally decided not to mass-produce and decided to concentrate on the next generation of MIX.
He also said that he will deliver a keynote speech on the 10th anniversary of Xiaomi, and he will answer more questions that everyone cares about in this speech.
When it comes to Xiaomi's self-developed chip, we have to mention the predecessor LC 1860 of the first generation s 1 shipped from Lian Xin. Its technology is SMIC's 28nm HKMG (high-K dielectric+metal gate), but at present, the 28nm produced by SMIC is not HKMG, but a traditional polysilicon gate. This door has low performance.
This kind of membrane can be used in low-performance scenes, but it is very troublesome to use in mobile phones. One of the consequences of HKMG metal mesh failure is that once the pipe speed is fast, there will be serious leakage. Later, the team left Lian Xin for Guo Song, and released S 1 28nm HPC based on TSMC. In 20 17 years, the hardware performance is fine, but the demand of this mobile phone software application is far from satisfying.
The road ahead is still very long. I hope Xiaomi can get better and better on the road of chip self-research!
