One thing I'd like to point here is that Apple bought all the 5nm from TSMC back in 2020. Who in the x86 world uses 5nm? The laptop from the video uses a Intel i9 12900H which is 10nm. The RTX 3080 Ti Mobile uses 8nm from Samsung. You can't tell me that a lot of the power savings you see from Apple isn't from their 5nm? Not only does 5nm give Apple a power efficiency advantage but it also allows them to pack more transistors. This is all hopefully after the pandemic silicon shortage. AMD's 6000 series mobile chips are now using 6nm while Intel has bought 2 years of TSMC's 3nm. Considering Nvidia is going to make the next generation Switch SoC, I can see them wanting to go 3nm as well. Considering Nvidia has worked with Samsung in the past, I can see them going with Samsung for 3nm.Even in the video you posted... this guy said as much, the M1 draws 1/4 the power from the wall while scrubbing around adobe premiere, and the same is true for stuff like Zbrush ect. Does it heat up like crazy if you try to render... of course, its not breaking the laws of physics, that just isn't something anyone making money on that stuff would be doing so who cares.
This is why I go after AMD parts for laptops to compare to the Apple M series and not the Intel+Nvidia combo. AMD's laptop APU's consume a lot less power compared to Intel, while offering good GPU performance. Add a discrete AMD GPU and you save a lot more in power consumption compared to Nvidia. As it stands AMD is on 6nm for mobile and 7nm for their GPU's. Once Apple goes 3nm next year with their M3 then their power efficiency will be even bigger. By then I would think Intel will start selling their 3nm chips because they did buy it for the next 2 years. By the end of this year AMD will be using 5nm. AMD Zen5 will be 3nm.... by 2024.
