ARM really isn't a generation ahead. Put a good x86 core on 5nm, and it might be slower but that's not a generation. Especially if you take generation to be like, pentium to pentium pro kind of leap.
Intel should have an escape plan off x86, but people are way way too stuck on the idea that x86 is a dead end when a good microarchitectural leap could offset it.
- dathinab 6y ago> a good x86 core on 5nm But that is actually Intel's problem, you can not "just" put a good x86 core on 5nm (technically) and you need 5nm production capacities to.
- mhh__ 6y agoBut what is 5nm, ARM is just an ISA, was my point.
- eptcyka 6y agoAt the end of the day, modern x86 cores are essentially high performing RISC cores with a vdry intelligent CISC decoder. An ARM core just has to be a high performing RISC core.
- astrange 6y agoARMv8 is not fully "RISC" insofar as that means anything. x86 is only "CISC" because "CISC" is defined as whatever x86 does.
- rurban 6y agoIf we are talking servers and IoT ARM is a generation ahead. Low energy, like 100x better. But also in pure CPU the latest aarch64 chips blow away Intel with its overly slow energy management, icache bloat and insecurity by design.
- tomjen3 6y agoHow could you offset it when you have no power budget to work with? The charger for my M1 is 30 watt. That can run the machine /and/ charge the battery. Even if a comparable intel machine can get that down to 45 watt, they still need a much bigger battery for the same operating hours, which means a heavier computer (or better battery tech, but a fundamental shift in the battery to e.g carbon based batteries is something I would expect from either Samsung or Apple). In a mobile world, power is what matters.
