New Huawei Kirin 9 chip may adopt ‘1+3+4’ 7nm CPU architecture

Huawei is developing a new Kirin 9 series chip for its devices, which could adopt a “1+3+4” octa-core architecture. It will likely be built on a 7nm process. This time, the company has improved its chipset manufacturing for better CPU performance.

FixedFocus notes that the upcoming Huawei Kirin 9 series chip may have a “1+3+4” CPU architecture. It will use one self-developed large core, three medium cores, and 4 small cores. It could also use an improved 7nm Pro Plus chipset platform.

A self-developed large core implies better and higher performance. These cores can easily handle heavy tasks like gaming, video editing, and more. The medium and small cores maintain balance and ensure a reduction in power consumption.

7nm Pro Plus hints at a more enhanced chipset platform. Huawei has said to improve its existing 7nm technology rather than focusing on the new 5nm or 3nm ones. The 7nm Pro Plus refers to the company’s new improvements in chip making.

The leak also implies that the OEM may use 8, 6, and 4 channels as per the chipset yield. Here, channels refer to a separate path that enables the CPU to access memory. The number of channels in a processor helps it to interact with memory modules.

For instance, the Quad Channel has four channels to associate with the memory module. The “6-channel and 8-channel” mainly used for servers. A high number of channels also increases bandwidth and results in dynamic computing performance.

Some netizens predicted that Huawei may bring two new Kirin chips for its Mate 70 series. The standard Mate 70 model could use the new Kirin 9 chip. Meanwhile, the high-end variants will likely adopt a 5nm processor with upgraded performance.

The prediction might be accurate to some extent. Huawei has been long-rumored to develop new Kirin chipsets for its flagship products. It seems the processors are in the final development phase and could show up by the end of this year.

Other details about the new chipset such as its name, official parameters, and internal changes are still unknown. Although we will discover these inputs probably with the Mate 70 series launch, seemingly scheduled for November 2024.
