Fanless M4 MacBook Air: Performance and Power Efficiency
2025-03-19
The new MacBook Air features a fanless M4 chip, offering performance on par with other M4 Macs. It boasts a 10-core CPU (4 performance and 6 efficiency cores) and a 10-core GPU. While sustained heavy workloads may cause slight performance throttling, it performs nearly identically to actively cooled M4 versions in most everyday tasks. Compared to the M3, the M4 offers a 15-30% CPU performance boost and a 10-20% GPU improvement. Against the M1, the overall performance increase is a substantial 50-70%. While it throttles under extreme stress tests, the M4 provides a noticeable performance upgrade for typical users, exceeding the needs of most daily workflows.
