著道 都慢; &化森nbsp; Th書弟e core of arm cur姐我rently is the comb術中ination core of a57 and a53 . 司國a57 has high performance and high姐河 power consumption , wh哥醫ile a53 has low黑放 performance and power consumptio都多n . Both can be independent and combine風河 into big or small core switch .
&n年通bsp; &nb光城sp; &nbs冷技p; In她老 the previous generation of a57 an光麗d a53, there are a15 and a7. a15好習 has high performance whi森煙le a7 has low power c這森onsumption .
