Apple Silicon is a line of processors designed by Apple Inc. for use in its devices, such as the Mac, iPad, and iPhone. Apple has traditionally used processors designed by other companies, such as Intel and Qualcomm, in its devices, but the switch to Apple Silicon represents a significant change for the company.

There are a few reasons why Apple Silicon is considered a game changer for Apple:

Improved performance and efficiency: Apple Silicon processors are designed specifically for Apple's devices and are optimized for their hardware and software. This can result in improved performance and efficiency compared to processors designed by other companies.

Greater control over the hardware and software stack: By designing its own processors, Apple has greater control over the hardware and software stack of its devices. This can allow the company to more easily integrate new features and technologies into its devices and optimize the performance of its software.

Potential cost savings: By designing its own processors, Apple may be able to save money on the cost of licensing processors from other companies.

Improved security: Apple Silicon processors include hardware-based security features that can help to protect against certain types of attacks.

Overall, the switch to Apple Silicon is a significant change for Apple and represents a major shift in the company's approach to hardware and software development. It is expected to have a significant impact on the performance and capabilities of Apple's devices, as well as the company's business model.
