Global semiconductor manufacturing has accelerated the switch to 5-nanometer process, and a number of 5-nanometer chip products have been released. At the apple new product launch on September 16, with the release of the new generation iPad air, the A14 bionic chip became Apple’s first mobile chip using 5 nm process. A14 is based on ARM cortex A72 architecture and consists of a new six core CPU, a four core GPU and a 16 core neural network engine. It also integrates machine learning controller and the second generation ml accelerator. < / P > < p > under the 5 nm manufacturing process, the number of transistors reaches 11.8 billion. Apple said CPU performance improved by 40%, GPU performance by 30% and machine learning performance by 70% compared with A12 bionic chip of the previous generation of iPad air 3. < p > < p > Apple also said that compared with other products, the A14 is six times faster than chrome book, three times as fast as the highest end Android Tablet, and twice as fast as the Current Windows laptop, although apple did not provide specific rival devices for comparison. In terms of AI performance, A14 can improve machine learning efficiency by up to 10 times with accelerator, and will greatly accelerate all future applications that use machine learning. < / P > < p > as there was no new iPhone released at this conference, the market tried to find clues about the new iPhone. At present, Apple has changed the practice of using A-Series processor for tablet products. The new iPad air is directly equipped with a series processor. Therefore, the market expects that the processor of the new iPhone released in the future may be the same as that of the iPad air. < / P > < p > with the release of A14, chip manufacturers have entered a climax in the production of 5nm chips. At present, 5nm chips are mainly produced by TSMC and Samsung, and the production capacity is extremely tight under the demand of large customers. As TSMC’s 5-nanometer process is more advanced, it has not been affected by the suspension of shipping to Hisilicon since September 15, and its production capacity has been split up by apple, Qualcomm and AMD. According to the supply chain news, with the launch of Apple’s new iPhone, nearly all TSMC’s 5nm production line has been put into production of A14 chips in the near future, accounting for about 80% of the production capacity, and will be shipped intensively in October, which is consistent with Apple’s earlier postponement of the new iPhone to October. < / P > < p > in addition, MediaTek, NXP and China’s three major AI chip companies have begun to introduce TSMC 5-nm process production. In order to meet the needs of customers, TSMC has decided to increase its capacity of 5 nanometers. In the fourth quarter of this year, it will increase another 28000 pieces, and increase its monthly production capacity to nearly 90000 pieces. < / P > < p > with the help of TSMC’s advanced process, amd has further indicated that it will adopt TSMC’s 5-nm process in the future, but the current new products are still dominated by 7Nm. According to AMD’s investor documents, AMD’s Zen 3 processor will still use 7 nm process instead of 5 nm, which is widely circulated. In the future, AMD will have to wait until the Zen 4 architecture, that is to say, the market will see 5 nm amd processors in 2022. < / P > < p > on the other hand, the order of 5-nanometer chips from Qualcomm has changed under the active efforts of Samsung. According to South Korean media business Korea, citing supply chain sources, Samsung has won an order for the 875 flagship chip of Qualcomm snapdragon, which is expected to be worth nearly 1 trillion won (about 5.75 billion yuan). According to the report, Samsung will mass produce these chips for Qualcomm to launch in December, which will be used in 5g smart phones of Samsung, Xiaomi oppo and other brands. It is said that “gta5” will be launched on Google cloud game platform stadia
