Do you have any data or reviews to link for that?

I'd really like to replace my old Thinkpad with a long-running, lightweight Linux laptop that can also do some gaming on the side (think Witcher 3 on good settings) but Snapdragon has not lived up to the hype AFAIK.

But big thumbs up to all the Linux devs that are working on improving the situation!

Not having the special hardware you are referring to means that the transpiled binaries have more fences than might be strictly necessary, which maybe gives a 5-10% performance hit depending on the use case?
