One of the reasons the Apple M1 was so amazing was because it based on a mobile-first architecture with efficiency as it's prime focus. This philosphy is beneficial for laptops because they are still battery powered devices with a limit on thermal capacity.
Innovative features like an ISP (Image Signal Processor) dedicated to processing images, Neural accelerators like Google's TPU, Qualcomm's Hexagon processor or Apple's Neural Engine dedicated for machine learning. Mobile chips are capable of operating at very low power during idle, which is achieved by using means such as Qualcomm's Sensing Hub or similar.
I was actually surprised to learn that modern CPUs don't have Neural Accelerators (Intel will include one for the first time in Meteor Lake) or ISPs (No wonder the webcams are so bad on PC!)
This is why I am excited for Qualcomm's eventual venture into the PC market with full force (thanks to Nuvia/Oryon IP). Qualcomm will bring these mobile first architectural innovations like the Spectra ISP, Hexagon AI processor, Sensing Hub etc... to their PC chips. These are all mature technologies, since Qualcomm has been working on these for years and implementing them in their mobile SoCs, and I am certain they will continue to be better than anything Intel and AMD can conjure, especially from an efficiency viewpoint.
