Reading on Wikipedia, manufacturing x86 chips requires a license from Intel for more advanced features, the 64-bit variant of x86 also requires a license from AMD. Is this really possible?
Intel, owns x86, AMD owns AMD 64. So to manufacturer a compatible x86-A64 CPU you would need to get licence.
Which they won’t give you since they don’t want competition.
There is a 3rd x86 license out there that was owned by Cyrix who was purchased by VIA and now Co owned by a Chinese company.

Intel and HP CO created IA64, and Apple, IBM, and Motorola Co created the Power architecture.
Part of why arm is used in everything is they license the crap out of it. And RISC V is fully open not requiring any license which is why it’s rapidly growing in popularity.
I keep watching RISC, running a lot of ARM stuff now expecially with Pis using it, but getting out of the licensing mess altogether seems like what we should all be aiming for. Plus it’s getting more advanced, and there are more things compiled for it, even RISC repos for distros designed to run on the chips.
I miss SPARC
DEC Alpha was massive at the time too - never really took off though.
Historically (and also currently somewhat), yes:
I would think all the patents have expired but there have been dozens of new instructions added since the 2003 x64. In many cases there are two variants of the same instruction so if a 3rd manufacturer came in they could make their own too. They would need Linux and Windows on board for their variants.
No
Yes it is possible and it is required. The cou microcode is patented and licensed. It’s why arm is such a unique and cool thing, arm is open and does not require a license. However converting enetirr architectures to arm is no small task.
arm is open and does not require a license
Arm is not open and requires a license.
RISC-V might be what they’re thinking of. An open-source architecture developed on the same principles as ARM.
Getting better all the time, though always seems to be several steps behind ARM in terms of performance. But the gap is narrowing.
Doesn’t ARM require an architectural license even if you aren’t borrowing IP cores? Apple paid big bucks for one.
Hopefully RISC-V takes over at some point.

Cause that is the point of the community?
Comment is deleted, but I’d bet it was something along the lines of “why don’t you google it, moron?!” which I always find funny on a text-based social media platform. The whole fucking point of this place is to discuss things.

I’m sure no one expects you to know anything. Certainly I don’t know why you can click on the community if you’re so hostile to the concept.

You have no idea. Others might. Again that’s the point of the community. So instead of denigrating someone for asking a question you personally don’t know the answer to just don’t comment at all.
Good rule of thumb: if you don’t know, don’t respond. You’ll see someone did post a credible and confident answer after your post.
I would think people should ask answerable questions.
They did and it was answered.
