What are the processors used in Macintosh and IBM compatible PCs?

Macintosh computers primarily use processors designed by Apple, with the shift to Apple Silicon starting with the M1 chip in 2020. Prior to that, Macs utilized Intel processors for many years. In contrast, IBM-compatible PCs predominantly use x86 architecture processors from Intel and AMD, with Intel's Core series and AMD's Ryzen series being the most common in modern systems. Both platforms have evolved significantly, with a focus on performance, power efficiency, and integrated graphics capabilities.
