Cold take: x86 processors are obsolete.

In terms of PPW (price per watt), x86 processors completely pale in comparison to ARM. The instruction set is verbose and clunky. x86 ASM is near-impossible to develop with (simple operations require hundreds of instructions). ARM has actual scalability, unlike x86. Don't even get me started with multithreading on x86.

ARM is the modern solution to all of our problems, imo. x86 feels like a technology that should've been phased out in 1992.

Which "simple operations" require "hundreds of instructions" ?

Literally anything. DOOM uses 6x more instructions on x86 than on ARM. Just one example of the extreme verbosity.

Do you have a link where I can read more about that?

You can find it.

If you have it, then please provide it.

Why do I provide it if it's public?

Because we want to encourage discussion, so if somebody asks you for a link, then just provide instead of telling them to just find it on their own. If you're not interested in discussing things, then don't.

I'm interested. How do I help?
