So, really, what this is saying is that a brand new, constructor specific 5nm SoC that is tailor made with a CPU/memory quasi-direct link is about equal to a year and a half old 7nm CPU, while being twice as expensive. As much as the Apple fanboys can scream about pOwEr EfFiCciEnCy!1, making up a $1500 difference just in electricity costs is going to be hard. Battery life doesn't matter, just plug your damn laptop, it's throttling itself if it's not plugged in anyways.
