No one is better than the other. Hisilent Kirin began with processors developed for the high-end market, and now there are mid-range processors equipped with Kirin 620 interviews. Hisilicon Kirin 620 oct-core processor is a 64-bit processor independently developed by Huawei based on ARM A53 architecture, with eight built-in cores that can work independently. It is built based on 28nm process, with a main frequency of 1.2GHz and a GPU of Mali-450MP4. Compared to the same frequency using the A7 architecture of the processor performance is 40% higher, and 64-bit software compared to 32-bit software performance is 25% higher on average.
Huawei Kirin is a chip product owned by hisilicon. So Hisilicon Kirin is the same product can not be compared.
