Apple's M4, M5, and M6 chips represent the latest evolution in Apple's custom silicon, and understanding their differences is key to choosing the right Mac. The M4 debuted in the iPad Pro, the M5 powers the newest MacBook Air, and the M6 has just made its first appearance in the Mac Mini. In this article, we break down what sets each chip apart and where you can find the best deals on the devices that use them.
Apple M4 Chip: The 3nm Workhorse
The M4 chip was first introduced in the iPad Pro and was specifically designed to drive the Tandem OLED display. It is built using a second-generation 3-nanometer process, which allows for improved performance and efficiency compared to its predecessors.
The M4 features up to 10 CPU cores: four performance cores for demanding tasks and six efficiency cores for lighter workloads. Its GPU also has 10 cores, making it well-suited for creative work and everyday multitasking.

Apple M5 Chip: Refined Performance
The M5 chip builds on the M4's architecture with further refinements. It is available in the latest MacBook Air, which boasts a 13.6-inch Liquid Retina display, a 10-core CPU, an 8-core GPU, 16GB of unified memory, and a 512GB SSD. The M5 also supports Wi-Fi 7 for faster connectivity.

While the M5 may have fewer GPU cores than the M4 in some configurations, it offers improved efficiency and is optimized for the MacBook Air's fanless design. This makes it an excellent choice for users who prioritize portability and battery life.

Apple M6 Chip: The 2nm Leap
The M6 is Apple's first chip built on a 2-nanometer process, marking a significant milestone in semiconductor manufacturing. This smaller process allows for more transistors to be packed into the same space, potentially delivering better performance and energy efficiency.
Currently, the M6 is only available in the new Mac Mini, which has just been announced but is not yet shipping. The M6 is expected to bring notable improvements in speed and power efficiency over the M5, but real-world benchmarks are still pending.
Key Differences Between M4, M5, and M6
- Manufacturing process: M4 uses second-gen 3nm, M5 likely uses an enhanced 3nm process, and M6 uses 2nm.
- CPU cores: M4 offers up to 10 cores (4 performance + 6 efficiency); M5 and M6 details are less clear but expected to be similar or better.
- GPU cores: M4 has up to 10 cores; M5 in MacBook Air has 8 cores; M6 details unknown.
- Availability: M4 is in iPad Pro and other devices; M5 is in the latest MacBook Air; M6 is currently exclusive to the Mac Mini.
- Connectivity: M5 supports Wi-Fi 7; M4 and M6 may have different wireless capabilities.
