HiSilicon from Huawei unveiled its latest mobile phone processor, the Kirin 990, at the IFA 2019 conference. Apparently, these chipsets will definitely work on the upcoming Huawei Mate 30 and Huawei P30 Pro series.
The 990 processor upgrades AI performance and communication capabilities, as well as well-known performance enhancements. Other features include an internal learning solution, an integrated 5G network modem, and enhanced image processing capabilities.

The most important feature of the Kirin 990 processor is that it supports 4G and 5G networks in a single package and can transfer data simultaneously across both networks for a secure connection.
The Kirin 990 processor is not supported for mmWave frequency bands, but this could be a big problem, as this chipset will not be going to the US anyway. Huawei says the Japanese market is a market based on a wide range of mmWave. However, it is considered an optional feature and is not mandatory in its current state.
Huawei still has a Balong 5000 modem, in case it wants to launch a phone capable of handling mmWave tapes, which can reach 2.3 Gbps for downloads and 1.25 Gbps for upgrading with the 5G network.
It is interesting to note that Huawei offers 4G and 5G versions with Kirin 990, 4G with download speeds of 1.6 Gbps, 5 channels for carrier aggregation and 4 × 4 MIMO format. This is a flexible strategy designed to reduce costs in markets where the 5G network will not be operational for a few years.
The Kirin 990 processor retains the same 2 + 2 + 4 design system introduced with the Kirin 980 processor, and exceptional performance has been extended with some response speeds resulting from Huawei's improvements and briefing on the Cortex-A76. At the same time, energy efficiency is maintained through the use of small and medium-sized clusters. However, the speed of response raises the processors to the limit, so we will carefully monitor all the indirect effects on energy consumption.
Finally, the Kirin 990 includes an upgraded version of the AI-based Kirin 980 programmer, which balances energy consumption and performance of the CPU, graphics processor and DRAM memory, and looks forward to the next frame to predict the future. Balance of resources needed to optimize efficiency. Power consumption and performance. Interestingly, the planner not only limits response speeds, but also dynamically manages the kernel to improve power management.
The Kirin 990 is Huawei's first processor to integrate NPU internal DaVinci architecture. This design first appeared in the Kirin 810 middle class earlier this year.
The 990 also has a small nuclear power plant for permanent operation applications, as well as a large nuclear power plant for bulky tasks. In fact, the 5G version of the Kirin 990 features a large NPU core for more processing power. The goal is to achieve the best balance in energy efficiency. The small NPU offers 24x energy efficiency for tasks heavy ones such as Screen.
