ARM vs x86 Competition

Discussions revolve around comparisons of ARM and x86 CPU architectures, focusing on ARM's advantages in power efficiency and performance per watt, Intel's struggles to compete, and the potential shift away from x86 in laptops, desktops, servers, and mobile devices.

No, it's a matter of someone making an ARM CPU that's worth using in a laptop/desktop. So far only Apple has, and they aren't sharing. The broader ARM market is still pretty weak & broadly uncompetitive with current x86 CPUs.In the server side of things there's Neoverse, graviton, etc.. which might have "trickle-down" effects but since it's primarily focused on just having more cores rather than faster cores that seems unlikely. And that also

Can anyone explain in a few sentences why the ARM architecture seems to outperform traditional CPUs so much? What fundamentally prevents Intel from building something comparable?

Title! “Why Cannot Intel Compete Against ARM by Sticking with x86?”

unixhero Feb 22, 2023 View on HN

Yes ARM isa requires less power. Why do you think we don't have mobile chips with Intel x86 instructions...

What is the long-term future for x86 as it gets squeezed from below by ARM?

Why would Intel stand still while arm improves dramatically?

Drill,The thing is that ARM licenses its core, while Intel doesnt. ARM allows many many silicon vendors to do their own thing. Make their own server CPUs etc. Something they had never been able to do before.I have no doubt that Intel will get competitive over time on the power front, if they are not already there yet. But people need to know that ARM is getting competitive on the performance front too. So that many silicon vendors, not just Intel, can come out with servers, and SOCs for o

The problem with arm is that it is lacking in software support and optimizations compared to x86; it's only recently that there's proof of viability of arm cpus outside mobile through apple, and they also have the advantage of full stack integration and over a decade of experience building the best performing ARM cpus.So there's a reason why they'd prefer x86. Hopefully they manage to release an ARM competitor for the desktop market, though with AI boom, it seems more like

Didn't Intel say this about ARM a while back?

jakozaur Mar 22, 2018 View on HN

Not surprised given:1. A lot of cloud services are abstracting CPU architecture. E.g. you don't care on which CPU AWS S3 runs.2. ARM is using less power than x86.3. ARM license fees are so low comparing to Intel high gross margins. Whole mobile world runs on ARMs and little profit is made on CPUs there comparing to Intel cash cow server chips.
