On September 15th, the U.S. ban on Huawei came into effect. After the ban came into effect, many manufacturers stopped supplying chips to Huawei. Among these manufacturers, TSMC, Qualcomm, Samsung, SK Hynix, Meguiar and other enterprises are no longer providing chips to Huawei. In addition, according to the news of Huawei’s industrial chain, Huawei did not prepare plan B at the same time when major manufacturers stopped providing chips. < / P > < p > although Huawei has been restricted in the production of mobile chips, AMD, the US processor giant, recently announced a piece of good news. The company said that it has obtained the supply license for Huawei, which may bring a first-line turnaround for Huawei’s related businesses. AMD is the first company to obtain the supply license to Huawei after the US ban came into effect. From this, we can see that the US ban is not like a barrel. In other words, AMD will resume its business with Huawei, and Huawei’s related business can also be further promoted. In fact, amd mainly produces PC chips. Huawei is also one of the top companies in China in the field of PC. Most of Huawei’s laptops are equipped with AMD processors, and they are still highly dependent on AMD. Therefore, Huawei’s notebook business will not be affected since amd announced that it has obtained the supply license. < / P > < p > it is worth mentioning that in addition to AMD obtaining supply license, according to foreign media, Intel, Samsung, TSMC and SMIC have also submitted license applications to the US Department of Commerce, and they all hope to continue to supply to China through the application. That is to say, if these manufacturers pass the application, Huawei’s chip supply problem may usher in a turning point. Even if Huawei can only sell these products to Huawei, we should understand that they can only pass the application. Huawei will be limited to the core technology of chips. In other words, they can sell the assembled chips and others to Huawei as long as Huawei does not engage in core technology. < p > < p > when it comes to mobile phone chips, we have to mention Huawei’s mate40 series mobile phones. Earlier, Yu Chengdong said Huawei mate 40 would arrive as scheduled. However, as time goes by, more and more news about the new mate40 series machines has been disclosed, and the appearance of the mate40 Pro phone has been basically confirmed. < / P > < p > as shown in the poster above, Huawei mate 40 Pro will adopt a waterfall screen with double holes in the front, and the rear camera will be a round Oreo four camera combination. The appearance of the whole machine is not different from that of the previous generation mate 30 pro. However, there are changes in details, such as the mate40 pro, which will retain the solid volume buttons, which is much more practical than the previous generation of virtual buttons. < / P > < p > in addition, in terms of endurance, Huawei mate 40 series will be equipped with 66 watt wired fast charging. In addition, there is a larger battery capacity, and the Kirin 9000 chip with the latest five nanometer process technology. I believe that this mobile phone will have a great improvement in the service life. < p > < p > Huawei mate40 series will definitely carry Kirin 9000 chip, but it is not clear whether the whole system is equipped with Kirin 9000 as standard. According to the information given by Huawei, the total production of Kirin 9000 chips is only 10 million. In the past, the sales of Huawei mate series mobile phones are far higher than 10 million, which is obviously not enough. < p > < p > therefore, Huawei mate40 series may adopt dual chip strategy, that is, the standard version of mate40 may adopt the MediaTek Tianji series chips, while the high configuration mate40 Pro will use its own Kirin 9000 chip. < / P > < p > finally, although amd has obtained the permission of the US Department of Commerce, it can continue to do business with Huawei. But at present, Huawei is still in a very dangerous situation. After all, the Kirin chip that Huawei is proud of can no longer continue to produce. It is not easy to break through this limitation. 865 optimization is different? These mobile phones should teach you a lesson!
