Apple Silicon refers to the new line of processors that power Apple's latest Macs. It is the term used to describe the in-house designed system-on-a-chip (SoC) that has replaced the Intel processors that previously powered Apple's computers. The shift to Apple Silicon marks a significant change in the company's hardware strategy, as it moves away from relying on third-party chip manufacturers and instead creates its own custom processors. Apple Silicon is a series of system on a chip (SoC) and system in a package (SiP) processors designed by Apple Inc., mainly using the ARM architecture. It is the basis of most new Mac computers as well as iPhone, iPad, iPod Touch, Apple TV, and Apple Watch, and of products such as AirPods, HomePod, HomePod Mini, and AirTag. Apple announced its plan to switch Mac computers from Intel processors to Apple Silicon at WWDC 2020 on June 22, 2020. The first Macs built with the Apple M1 processor were unveiled on November 10, 2020. As of January 2023, all newer Mac models are built with Apple Silicon; only the older model Mac Pro still uses Xeon processors. The Apple Silicon processors are designed to be faster, more power-efficient, and better integrated with other components in Apple's devices, such as the graphics processing unit (GPU), neural engine, and memory. This level of integration results in improved performance and power efficiency, which translates to longer battery life and faster processing speeds. Apple Silicon processors are based on the Arm architecture, which is commonly used in smartphones and tablets. This allows Apple to make more power-efficient chips that consume less power than traditional desktop processors. Additionally, because Apple designs the entire system, from the processor to the software, it can optimize the hardware and software to work together seamlessly. The move to Apple Silicon has been widely praised by experts and users alike, with many noting the significant improvement in performance and battery life. It also means that Macs can run iOS and iPadOS apps natively, making the ecosystem more integrated and seamless. Overall, Apple Silicon is an impressive achievement in hardware design, and it showcases the company's commitment to innovation and excellence. With the introduction of these powerful and efficient processors, Apple has ushered in a new era for its Mac lineup, providing users with a more powerful, efficient, and integrated computing experience. Apple fully controls the integration of Apple Silicon chips with the company's hardware and software products. Johny Srouji is in charge of Apple's silicon design. Manufacturing of the chips is outsourced to semiconductor contract manufacturers such as Samsung and TSMC.
