Huawei has unveiled the HiSilicon Kirin 9000 5G chipset, along with the Mater 30 series. The new SoC is a 5G capable design that can also easily handle multi-tasking operations and intensive computations. With the more advanced 5nm manufacturing process, we can be certain that the chipset could deliver better power efficiency and performance. It’s a direct replacement over the Kirin 990 5G, which is built using the 7nm process. The Kirin 9000 5G is consisted of 15.3 billion transistors, which is quite impressive, because it’s the first mobile processor with more than 15 billion transistors. As comparison, Apple’s new A14 Bionic SoC has less than 12 billion transistors. Although the number of transistors doesn’t directly translate to better performance or more features, it is still an interesting detail to know. Although Kirin isn’t a very popular mobile CPU platform, the Kirin 9000 is actually quite impressive, in terms of architecture and design.
The Kirin 9000 5G is an octa-core design with three levels of power utilization. There’s a single 3.13GHz Cortex-A77 core, which is the most powerful, but also consumes more energy. There are three mid-performance Cortex-A77 cores clocked at 2.54GHz each. For low-energy functionality, such as navigating the interface or checking emails, four highly efficient Cortex-A55 cores can be enabled and they run at 2.04GHz each. It’s also interesting to note that Kirin 9000 5G has the highest clocked core, because the Qualcomm Snapdragon 865 Plus currently runs at 3.1GHz max. The Kirin 9000 5G comes with the Mali-G78, which is a 24-core GPU, which is the most powerful GPU ever used on a Huawei device. The previous Mali-G77 GPU is known to be more powerful than Adreno 640, so we could assume that Mali-G78 should approach the performance level of Adreno 650. If it’s true, the Kirin 9000 5G may be equal or just under Snapdragon 865, in terms of graphical processing and gaming performance. In fact, Huawei claimed that the Kirin 9000 5G is 10 percent faster than Snapdragon 865. When it comes to data networking capabilities, the Kirin 9000 5G support 5G, 4G, 5GHz WiFi and 2.4GHz WiFi. This ensures that any Huawei phone with Kirin 9000 5G could maintain good connection, regardless of the changing conditions.
Huawei also announced the Kirin 9000E chipset. It still has the same octa-core configuration with one high performance 3.13GHz Cortex-A77 core, three mid-performance 2.54GHz Cortex-A77 cores and four energy-efficient 2.05GHz Cortex-A55 cores. An obvious reduction is that the Mali-G78 of Kirin 9000E, has only 22 cores, instead 24. There’s a similar downgrade to the NPU module, which only has one small core and one large core. Other details are identical, like the inclusion of security module, ISP 6.0, Balong 5000 5G baseband and others. The Kirin 9000E is still manufactured using 5nm EUV process. There are supports for 4K HDR video, HiFi sound quality, UFS flash memory, LPDDR5/4X RAM and others.
Snapdragon 875 is expected as Qualcomm’s first 5nm SoC, which be used by flagship Android devices in 2021. It is also important to note that future 5nm chipsets, including Exynos 2100, will use Cortex-X1 and Cortex-A78 cores, which are faster than Cortex-A77 and Cortex-A55 cores.
