Yeah but they weren't running both in the same device at the same time.
PPC -> Intel they just recompiled their OS and fixed it up for the x86 platform, then the same for Intel -> ARM
They did not have a laptop with an x86 processor and a PPC at the same time.. though there are some hillariously bespoke accellerator cards from back in the day to do all sorts of strange things.
That said, laptops are full of microcontrollers with firmware, lots of those will be atmega, st32, 6502 and the like. Things like a WLAN or WAN card will be a little ARM soc of some flavour.
So it really depends on where you draw the line. If its executing the main workload, I'd say thats the CPU, everything else is a microcontroller enabling it to do that
Its actually not seperate cores, they're RISCV or ARM, based on a switch. MilkV does that too with one of its chips. They're mostly the same architecturally, theres something like 10% that gets enabled/disabled with each ISA selection.
I've got a $1 linux embedded SoC that has a 64 bit riscv core, a 32 bit riscv core for running realtime stuff and a low power embedded 6502 on it too because why not.
SEC is neutered, what makes you think anyone in charge of advertising rules hasn't been replaced by a 17 year old called Goebbels Gobbler or something with a DOGE laptop.
Stop talking. Prompting isn't working. I know, because I do it all day.
Everyone should just stop talking about it at this point and only look at the quality of their output. If you're AI-assisted and your shit still sucks then that's just you sucking shit.
My point it isn't 2x arm and 2x riscv. They recycle most of the silicon used.
