M4 MacBook Air Utilizes All Six Efficiency Cores Instead Of The Performance Ones In Heavy Workloads To Improve Battery Life, Showing Major Constrast With Earlier M3 Version – Wccftech

🔍 Summary:

Apple has launched its new 13-inch and 15-inch MacBook Air models equipped with the M4 chip, and early tests reveal intriguing changes in how these devices manage processing tasks. YouTuber Vadim Yuryev from the channel Max Tech found that when running Adobe Lightroom Classic, a CPU-intensive image editing software, the M4 MacBook Air primarily uses its six efficiency cores instead of its performance cores. This is a significant shift from the previous M3 model, which relied heavily on performance cores for the same task.

The use of efficiency cores for demanding applications is unusual and suggests that Apple may have optimized the M4’s Neural Engine to determine which tasks can be efficiently handled by these cores, potentially enhancing battery life and reducing heat. This approach could help avoid thermal throttling, especially since the M4 MacBook Air lacks an active cooling system and uses a single large heatsink for heat dissipation.

Further investigation is needed to confirm if this behavior extends to other intensive applications and to fully assess the impact on performance and user experience. Meanwhile, Apple is promoting the new MacBook Air models with a $50 discount on Amazon, making it an opportune time for consumers to explore these advancements themselves.
