Apple’s passive cooling problems were evident in its second-generation single-chip systems.
The new MacBook Air has received full-fledged reviews on the Web. It is built on the SoC M2 which only has a passive CO. This means that in many tasks, the M2 is slower than the M1.
The charts show that the new MacBook Air performs less under constant load than the MacBook Pro running on the same platform. Although there is still a slight increase in performance relative to the MacBook Air before, it is much smaller.
Important is the bottom right diagram after loading for 30 minutes.
It is because the platform overheats, and throttle comes into play. The same MacBook Air M1 performs worse when under long load. Performance drops by 21% and 13% respectively. The new SoC M2 isn’t as good in absolute terms but is better in terms of energy efficiency.
