1. Different architectures are adopted. The Kirin 990 uses the A76 architecture, and in a gradual way, the Kirin 9000 will use the A78 architecture.
2. The process technology used is different. The Kirin 9000 processor uses the latest TSMC 5nm process, which can accommodate 1.713 transistors per square millimeter, while the Kirin 990 processor is an eight-core processor built using a 7nm process.
3, performance is different. 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.
