This week people get the new M4 MacBook Air in their hands, which means that they post many discoveries about their performance (and the blueness of the new sky -blue color). While editing photos in Lightroom Classic, youtuber Vadim Yuryev noted that the CPU workload was almost completely treated by the six efficiency names of the laptop.
Placed by WCCFTech, this behavior is interesting because the software for editing images is so CPU-intensive that everyone would assume that it needed the performance charts to turn. This was certainly the case for the M3 MacBook Air, which shows Yuryev with the help of all four performance and all four efficiency scores to do the work.
We do not know why this behavior has changed, how targeted it is, or whether it is specific to Lightroom -classic – but the benefits can be considerable. By keeping the efficiency cores busy and limiting the activity on the performance cores, the battery can improve the lifespan and keep the temperatures low.
That said, we don't know from Yuryev's post how well the software is running in this state – we can assume that he points it out because it's fine, but we don't know for sure.
It is also not entirely impossible that this is a kind of bug – the performance cores are there to be used, or else they would be useless. So the enormous amount of activity on the efficiency cores, while the performance nuclei are almost unused, seems quite strange.
With points of sale such as WCCFTech and Tech influencers everywhere experiment with this new model, we will probably quickly discover whether this was a chance goal or an intended function of the new MacBook Air.
