There are two main differences between the Kirin 990 and Kirin 9000 processors:
1. Different structures:
1. Different CPU architecture, Kirin 9000 adopts 1*Cortex-A77@3.13GHz 3*Cortex-A77@2.54GHz 4*Cortex-A55@2.05GHz. The Kirin 990 adopts 2*Cortex-A76@2.86GHz 3*Cortex-A76@2.36GHz 4*Cortex-A55@1.95GHz;
2, GPU architecture is different, Kirin 9000 adopts 24-core Mali-G78, Kirin 990 adopts 16-core Mali-G76;
Second, the processor is different: the Kirin 9000 processor adopts the latest TSMC 5nm process technology, which can accommodate 1.713 transistors per square millimeter; The Kirin 990 processor is an eight-core processor built using a 7nm process.
The Kirin 990 adopts the A76 architecture, and the Kirin 9000 will gradually adopt the A78 architecture.
