Apple switched to using ARM processors in the MacBook instead of Intel processors for several reasons:
- Power efficiency: ARM processors are known for their power efficiency, which allows for longer battery life and less heat dissipation. This is important for portable devices like laptops, where battery life is a critical factor.
- Performance: ARM processors have improved in terms of performance and can now rival the performance of Intel processors for many tasks, including those that are typically performed on a personal computer, such as web browsing, office work, and video playback.
- Integration: ARM processors are designed to be integrated with other components, such as memory and storage, which can help to reduce the size and cost of the final product.
- Control of the hardware and software: By using its own ARM-based processors, Apple can have more control over the hardware and software of its devices, which can help to optimize performance and battery life.
- Cost: ARM processors are generally less expensive to produce than Intel processors, which can help to reduce the cost of the final product.
- In-House Development: Apple designs its own ARM-based processors for its devices, this allows them to develop and improve the processors in-house, which can help to reduce costs and improve performance.
- Compatibility: ARM processors can run macOS as well as iOS apps, which can help to increase the compatibility of the MacBook with other Apple devices.
Overall, the switch to using ARM processors in the MacBook was made for a combination of reasons, including power efficiency, performance, integration, control, cost and compatibility. This switch also allows Apple to have more control over the hardware and software of its devices, which can help to optimize performance and battery life.
