Apple MacBook Air 15-inch - M3 Chip. The Midnight Apple 15" MacBook Air now features the Apple M3 chip, which has many improvements over its predecessor, the M2. Now built on 3nm process technology, the M3 8-core Chip is combined with a 10-core GPU. The next-gen GPU features Dynamic Caching, hardware-accelerated ray tracing, and mesh shading, all of which significantly increase performance for the most demanding creative apps and games. The M3 Chip also has a 16-core Neural Engine that can leverage the power of AI for both macOS and a growing number of supported apps. It also has 8GB to 24GB of unified RAM and a 256GB to 2TB SSD. Add Wi-Fi 6E (802.11ax) and support for two external displays, and this MacBook Air delivers performance, power efficiency, and portability. Apple M3 8-Core Chip. Now packed with 25 billion transistors, five billion more than M2, the Apple M3 integrates the CPU, GPU, Neural Engine, I/O, and more into a single system on a chip (SoC). Now built with 3nm process technology, the Apple M3 8-core chip features four performance cores and four efficiency cores, which is up to 35 percent faster than M1 for CPU performance.
