Emulators uses the system's processor to emulate the hardware to trick the game into running, so running it on a low performance chip will cause your system to slow down. This is where hardware acceleration comes in, it handles the emulation leaving the processor free to do the day to day task.Emulators don't require hardware emulation from the processor though. They do the emulation, not the processor.
Basically what I'm saying is that you are not going to run Cyberpunk in emulation on Android.
