Europeans have less brand loyalty as a whole, I know a lot of central europeans who are quite thrifty (or, very value conscious at least). And it's not as if we don't see that AMD is crushing intel at this point. So shouldn't the title be "Humanity prefers AMD"? or are Americans/Asians really buying intel over AMD still?
That's possible, brand loyalty is a thing. Not that I have good data about this, but I definitely saw people not even considering AMD because they always bought Intel. Same for Nvidia with GPUs.
In France I saw PC shops that had not a single AMD motherboard or processor. That was during the FX era, but still. Ryzen will have changed that situation a bit, but I doubt it's complete. During the same time AMD was still surprisingly popular in Germany.
Markets are often not reasonable.
To be fair, they're still close enough that it doesn't _really_ matter for most people since performance will be about the same for their tasks, which is why it's so hard to get people to switch their buying patterns.
I think there's also a rational aspect for some groups. Developers and related groups probably have outsized influence over what the whole market chooses. I e.g. do plenty low level performance work, and like 95% of installations of software I work on are on x86 Intel CPUs. Therefore getting an AMD CPU will make it harder for me to sensibly diagnose performance issues. So I get laptop / workstation w/ Intel CPUs. And in turn I have less data to recommend deploying on AMD servers.
Strong brand loyalty is sometimes rational for some groups, but not for the market overall
Perhaps partly because AMD (and then later GlobalFoundries) has fabs in Dresden, Germany.
Although AMD is competitive on the low end, in the high end GPU market AMD isn't even close to Nvidia on raw power or efficiency. Hopefully they can change that soon because Nvidia really needs solid competition
It's only the high highend where AMD has nothing. AMD did fairly well with the RX 5700 now in the lower highend, clearly better offers in that segment. So the situation already improved there. On the other hand, right now with the GTX 1660 (Super) Nvidia is stronger in the $200 to $300 segment.
