The difference is that the CPU runs at different speeds.
One, Kirin 9000
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 an architecture consisting of one 3.13GHz A77 large core, three 2.54GHz A77 medium cores, and four 2.04GHz A55 small cores, with a 24-core Mali-G78 GPU.
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.
According to the latest news, Kirin 9000 will have strong 5G capabilities, AI processing power, more powerful NPU and GPU;
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.
