Huawei’s 5nm chip Kirin 1020 is stable, and it hangs Snapdragon 865?

On March 12th, since Qualcomm officially released the Snapdragon 865 processor, the entire mobile phone circle can be said to be in a carnival. Since other manufacturers other than Huawei in domestic mobile phones basically use Qualcomm processors, Huawei’s 5G chip Kirin 990 It was released as early as last September.

Although the Kirin 990 can only be said to be on par with Qualcomm’s latest processor, the Snapdragon 855, in terms of performance, it is definitely ahead in terms of process technology and support for 5G mode.

After the release of the first Snapdragon 865 processor mobile phone Xiaomi 10 series, Lei Jun, Lu Weibing and other Xiaomi executives even sneered at Huawei Kirin 990. But Huawei can only be a man with its tail between its tails. After all, in front of the powerful Snapdragon 865, the Kirin 990 is not enough in terms of overall performance or 5G speed. Huawei’s hard days are coming to an end. According to the latest news from the supply chain, TSMC will start mass production of 5nm chips in April, and the production capacity of TSMC’s 5nm process has also been fully booked by relevant customers.

The specific physique of Kirin 1020 has not been exposed yet. After all, it will not be released until the second half of the year, but we can guess its performance based on the current information.

The first is the improvement of the process. The upgrade from TSMC’s 7nm to 5nm means more transistors, which can effectively reduce power consumption while improving performance. Huawei’s next-generation Kirin chip will use TSMC’s 5nm process. As one of TSMC’s most important customers, it has fully booked TSMC’s 5nm process with Apple. The name of the next-generation Kirin chip is 1020.

However, Qualcomm has not been able to come up with a 5nm solution, because the 5nm process is extremely complex, and the cost of a tape-out will cost hundreds of millions. Qualcomm may have “can’t afford it”. This means that for a long time, the Android camp will only have Kirin 1020, a 5nm chip, which may win in performance.

In terms of architecture, the Kirin 1020 in the second half of the year will definitely use the A77 architecture, and it will even directly use the A78 architecture across generations, but the latter is less likely. Even the former, the A77 architecture has nearly 20% performance improvement compared to the A76.

In terms of GPU, Huawei Kirin has always used Mali’s architecture, which has natural deficiencies compared to Qualcomm’s Adreno architecture in games. However, after the Kirin 970, Huawei officially released GPU turbo to make up for the lack of GPU performance.

The baseband part, although strictly speaking cannot be a part of the processor, but considering the integrated baseband, it is also mentioned together. As the No. 1 communication manufacturer, Huawei naturally does not need to worry about baseband. The Baron 5000 also shows us Huawei’s strength in baseband. It is believed that the next generation baseband will only be stronger.

The Kirin 1020 that Huawei’s Mate40 series will carry in the second half of the year is built with TSMC’s 5-nanometer process. After a little analysis, we know that it is Huawei. Apple’s iPhone 12 is also released in the second half of the year, and it has also eroded a lot of 5-nanometer chip production capacity. It can be said that only Huawei and Apple will really launch 5-nanometer chips this year. Huawei’s side is naturally Kirin 1020, while Apple’s side is A14 .

Once the Huawei Kirin 1020 is released, the Snapdragon 865 will be a generation behind. Not to mention the performance, first of all, the 5-nanometer technology will completely explode the 7-nanometer. Second, Huawei has confirmed last year that it will definitely meet the A77 under the 5-nanometer technology. In terms of GPU, Kirin 1020 may debut Huawei’s self-developed “taishan” architecture.
