APSS provides more P-states than _PSS on apple macs, for example on MacBookPro11,3 _PSS provides 17 P-states ranging from 800Mhz to 2301 Mhz, while APSS provides 28 P-states ranging from 800Mhz to 3500 Mhz Same with ACST, on Xserve3,1 _CST provides 2 C-states (C1, C6) while ACST provides 3 C-states (C1, C2, C6). This is also used in older macs only (before 2015). And also macOS uses these.
