this is not a professional test but i want to share my thoughts about the new ARM chips for Windows in comparison to the M3 ARM chip of Apple. really great to see that there is competition again between Windows and Mac.
It is not a simple video - it is 4K but I do appreciate and get the point. This makes the point that those chips just use too much power. Or maybe we are spoilt to think 4K should take much power to playback. I really love those video.
If you also take into account, that Intel based computers are typically loaded with bigger batteries around 60-80 Wh, except the Microsoft Surface Laptops (which are around 50 Wh, even with the Intel versions). The ARM based devices shown here are at around 52 Wh (Apple) and 54 Wh (Microsoft Surface Laptop 7th gen). This shows: in Performance per Watt is also very much better.
