Apple recently announced two MacBook computers powered by its new M1 chip. The new Apple Silicon laptops are not just the fastest ever made, but also the most efficient. For example, one of the benefits Apple claims is dramatically longer battery life for the 13.3-inch MacBook Air and MacBook Pro.
The MacBook has always been known for excellent battery life, often enjoying more than a few hours lead over most PC laptops. The only real challenge in the past came from various Chromebook models that typically rely on an in-browser experience. However, a MacBook is a full-fledged computer, so its efficiency earned high marks in head-to-head comparisons with other laptops. In more recent years, the situation has changed, notably with higher-end notebooks like the Surface Book and Dell XPS line matching run time. Qualcomm's Snapdragon-powered PC laptops also now offer competition in the battery space, thanks to the Snapdragon 8cx platform.
The M1 chip inside the new A14 powering the iPad Air 4 than with any processor made by Intel or AMD. Apple claims this new technology has the highest performance per watt of any U. The M1 has a unified architecture that eliminates repetitive movement of data between U, GPU and Neural Core, improving both speed and efficiency. For example, the MacBook Air boasts up to eighteen hours of battery life while the MacBook Pro goes even further, lasting for as long as twenty hours on a single charge.
What Makes The M1 So Efficient
Intel is using a 10-nanometer process and AMD uses 7-nanometer. The smaller size almost automatically offers better performance and efficiency, since the electronic signals within the chip travel shorter paths. Apple’s advantage is more than just process scale, though. The unified architecture means all components on the M1 chip can access memory, whereas older technology must copy data to memory that is accessible to the GPU or neural processor.
The other piece of the puzzle is Apple’s unprecedented integration. Apple controls every aspect of the MacBook, deg the chips and developing the macOS operating system. This means there is an opportunity to refine both hardware and software at every step to optimize speed and efficiency without the restrictions that face those working on isolated components, as is often the case with PC laptops. Due to this great synergy, the new M1-based MacBook Air and MacBook Pro offer better battery benefits than ever before.
