They're not a ridiculously large jump, not on the overall scale of performance. There's nothing in an M1 that we couldn't do before, or haven't done before. High end SoCs have always had insane performance. However, slap literally any high end CPU of today on a SoC and you get the same results. Apple didn't invent new tech, didn't create performance out of thin air.
However, they did just force you to buy a new $2000 machine next time you want to upgrade in 3 years because it's a single, monolithic block.
>Let me know when other manufacturers figure out how to cheat in software/process-node/whatever and I’ll consider them.
Unfortunately, they all accept to be part of a greater ecosystem that doesn't attempt to fuck you over by being un-upgradable and incompatible with each other, so cheating is out of the way.
