Quad-core refers to four processor cores with the same functionality on one processor based on a single semiconductor. In other words, four physical processor cores are integrated into one core.
The difference between quad-core and dual-core is that for multi-tasking, four-core CPUs open four programs faster than dual-core CPUs, and that is multi-core has greater advantages in large-volume operations.
The Mario Android TV box uses a quad core processor and an octa core processor.
Octa core refers to the integration of eight physical processor cores into one core. Running faster, the game is not stuck.
