January 11 news, #iPhone 15 or will be equipped with Apple's self-developed chip # rushed to Weibo hot search first.
Nikkei Asia recently reported that Apple plans to launch the first self-developed 5G baseband chip in 2023, and is currently establishing a closer cooperative relationship with TSMC to reduce its dependence on Qualcomm. According to the latest news from the Liberty Times, Apple's self-developed 5G baseband chip has been developed and will use TSMC's 5nm process, with an annual production capacity of 120,000 wafers.
Previously, Tianfeng International analyst Guo Mingqi had said that Apple's 5G baseband chip would debut in the iPhone model in 2023 as soon as possible. Qualcomm financial officer Akash Palkhiwala also revealed that it is expected that the proportion of Qualcomm 5G baseband chips shipped in 2023 will be reduced to 20%, which also hints at the arrival of Apple's self-developed 5G baseband chips.
All kinds of signs show that Apple's self-developed 5G baseband and RF modules have made good progress. Apple has a good accumulation in chip design, mobile phones, tablets on the A series of chips, and MacBook on the M series of chips, have shown great strength, they have strong performance at the same time, power consumption is not high. In particular, the M series of chips makes the MacBook have a strong battery life.
Apple designs baseband chips, which are more of a communication problem. Apple didn't build the entire baseband manufacturing team from scratch. Previously, Apple and Intel jointly developed baseband products. Intel subsequently exited the market and sold the team to Apple. Apple has also poached a lot of people from Qualcomm, and its self-developed 5G baseband is quite worth looking forward to.
The signal testing process is more complicated, and in the years when the iPhone used intel baseband, the signal was indeed very weak. After switching to Qualcomm baseband on the iPhone, the signal was a little better, but it didn't seem to be particularly good either. Xiao Lei uses Unicom, coordinates Guangzhou, in the same place, the same use of 5G, Xiao Lei's Xiaomi 10 Pro can better receive the signal, cellular data transmission is smoother, and the iPhone 13 mini Internet access is stuck, can not brush out things. Although a single location does not explain too much, it does feel like the iPhone's signal is average when used.
Signal problems have become the shortcomings of the iPhone, and it is necessary for Apple to personally go down and master the baseband technology in its own hands, so as to have a higher product power.
