The Kirin 9000 processor uses the latest TSMC 5nm process and can accommodate 1.713 transistors per square millimeter, which is almost 12 billion transistors according to the area of the Kirin 990.

The Kirin 9000 uses the Cortex-A77 Cortex-G77 architecture; The second is: Kirin 9000 will use Cortex-A78 Cortex-G78 architecture;
< br >
The main reason is that the Kirin 990 adopts the A76 architecture, in accordance with the gradual way, the Kirin 9000 will adopt the A77, and in addition to the two sanctions of the United States, Huawei is likely to not get the authorization scheme of ARM.

Kirin 9000 has strong 5G capability, AI processing power, more powerful NPU and GPU, and the Kirin 9000 adopts the A78 architecture has been firmly hammered.
< br >
Through the architecture of the chip, it can be seen that compared with A78 and A76, CPU and GPU performance have soared, the overall performance has increased by 50%, and the overall chip performance is far superior to that of Snapdragon 865, which can reach the level of 875.

2. Kirin 990
Qilin 990 processor is an eight-core processor created by 7nm process technology. The CPU part adopts three-cluster design, 2 A76 super core, 2 A76 large core and 4 A55 small core design, which can fully mobilize the hardware resources of the system. Combined with 7nm process, the overall power consumption level is very good.

In terms of GPU, it is a breakthrough using the 16-core Mali-G76, and the performance and energy efficiency are first-class. At the same time, Huawei also has GPU Turbo 3.0 technology and Kirin Gaming 2.0 technology, which can give full play to the performance of mobile GPU, so as to have a very good performance in the actual game experience.
< br >
The most outstanding part of Hisilicon Kirin chip in the past two years is that the built-in NPU greatly improves the AI performance of mobile phones. In this year's Kirin 990 chip, Huawei's self-developed Da Vinci architecture NPU also played a good strength, the large core and micro core computing architecture, the large core is responsible for the large computing power scenario, and the micro core is to complete the low-power application scenario, so that performance and power consumption balance.

Iii. Summary
Kirin 9000 has greatly improved its chip manufacturing process and architecture compared to Kirin 990. In GeekBench4's test results, Kirin 990 scored 3838 points for single core and 11,934 points for multi-core, which is a very good performance.
