I'd probably give the Macbooks (or this new Thinkpad) a closer look if I didn't work with Docker constantly. As it stands though, ARM and x86 are still not like comparisons, and still not even remotely capable of the same workloads. I have high hopes for the future of RISC arches, but we're undeniably trapped in an age of x86 dominance.
I've got a 460s and it will run pretty warm if you let it. If you tell it to not run so hot it'll keep the CPU throttled down a bit more aggressively and keep it cooler. That generation of Intel CPU was always a bit on the warm side when it wanted to actually do anything. Especially anything related to video encoding/decoding, using stuff like Zoom or Meet or Teams really makes the machine get warm.
The machine can definitely run pretty hot if you crank the performance profiles though, that's for sure. I've managed to hit 70c while playing music/running CPU intensive games on an external monitor, and I definitely think you could push it further with more CPU twiddling. For regular use though, a hearty underclock still renders the device usable with low temps and a good amount of battery life extension.
Like I said, ARM may well have it's day, but right now it's just full of compromises that I simply can't make. So long as x86 benefits from the same big.LITTLE architecture that ARM has been transitioning to, I don't think I'll really have much use for another arch until RISC-V hits the mainstream.
One has to think that all these users who can't seem to configure and operate Windows properly are probably not configuring and operating Linux (which exposes much deeper control and complexity to the user) properly either. "It's a poor craftsman that blames their tools", after all.
