Leading Semiconductor Industry Players Join Forces to Accelerate RISC-V

There's no technical reason, but there are economic reasons. Only three companies have proven that they can build such a core for the mass market: AMD, Apple, and Intel. Designing a big core takes time and effort which is directly proportional to money.

The cortex x line arent small either.

and its arms insane price hikes that is moving above mentioned companies to move away from arm

Yup, they're seeing the writing on the wall with per device sold fees and just not having it.

They'll move back to x86 instead, no one's going to RISC-v just because they want to.

You're not making microcontrollers and embedded controllers with x86, no way about that. If it's not RISC-V it will be back to mips and exotic one offs with everyone doing their own thing

 

[R0H1T]

How old are these controllers?

That's still the case for a lot of them & I doubt that changes with a cheaper alternative to ARM.

Why not go full speed on an empty autobahn?

Autobahn is different. Caveat emptor.

 

[trsttte]

Honestly there are speed limits that are completely nonsensical and having some iot thing try to enforce them will only help illustrate that. I comute through a speed limited and heavily monitored highway that's always congested because the limit is too slow for the type of road and doesn't allow enough "bandwidth" let's call it of cars in rush hours

no one will move to X86 because it's not a microcontroller-friendly uarch, there's no way to scale it down like RISC-based uarchs such as ARM and risc-v, RISC-V is open source and proven already.
Plus intel does not license X86 to anyone anymore.

 

[R0H1T]

Scale down how, or to what limit? If you're talking about chips that go into a calculator, universal remote, smart appliance or any other consumer electronics products the vast majority of them are already proprietary. The upcoming "smarter" chips are a mess & security hellhole. If you're talking about size sure that may work but that also means that x86. & ARM, will lead the top end performance race for some years to come especially AMD/Intel because it's just as hard to scale chips up as it is to scale them down.

Depends on what you mean by proprietary, about everything is proprietary. If you mean exclusive they aren't, they mostly are either MIPS, Cortex (arm), powerpc, Z80 (like most texas instruments calculators to this day!), or some others. They're proprietary but also commonly licensed architectures.

x86 is unworkable for embedded aplications because it's basically an Intel and AMD exclusive - who aren't really interested in the embedded market - and too big and complex (not to mention power hungry) for a very small device like a smart switch or tv remote.
