I'm familiar with that attitude. But many of the people who prefer AMD to Intel did not like ECS, Biostar, VIA, SiS... or Samsung.
I doubt AMD ever had a CPU that could beat Intel's. AMD did have some success into supercomputers and high-end computing, but it was usually Intel that have kept rising, growing, and getting better and better.
Several years ago, or 12 years ago when SiS was still making popular chipsets for DDR memory chips and AMD Hammer processors, the same AMD fans - which I preferred calling fanatics though I too had more than ten motherboards compatible with AMD only - kept on insisting AMD could somehow beat Intel. Check out the facts... the balance sheets of both AMD and Intel have been available on their websites. AMD simply didn't have the money, or the resources to develop, produce, and distribute as well as Intel.
'More bang for buck' theories usually only work for the ones that chose them. I've seen people saying "I will never buy any HP product again" or "I will never buy anything Samsung sells again", but... what do those public announcements change? People always try to argue and influence they know in person or just about all unknown visitors or searchers so that they would also hate the same brands. That's one aspect of the social networks I never liked, but somehow Chinese created and made their own networks... larger and far more powerful than the Western versions. How that will turn out will surprise everyone - including every Chinese.
I spent my own money and time to make more people use and own AMD systems. One of the better advantages then was DDR support. AMD systems also offered much lower initial cost of ownership for dual CPU motherboards. That was some years before Intel switched to multicore strategies seeing Sun Microsystems advertising 32-core and some others talking about many more cores. But that's another story. AMD probably once or twice had chances, but so did SiS and Via. Sun and DEC, too. It's Larry Ellison, by the way, that now owns Sun. It must have been a coincidence one of his yachts was named Rising Sun. I was just reading about the book The Rising Sun.
My point is AMD or Intel, Samsung or Apple, they are all just businesses. Some donate, and even donations are usually business acts. They are not meant to help all the world's 'underdogs' to make better lives or get more for less. Things might have seemed different, but from here it was always Intel that looked clean and AMD was always the one arrogant and dirty. Same about Samsung and Apple. Samsung's criticized for being massive, industrial, polluting, powerful, evil, centralized, authoritarian, even making arms and tanks and fighters and warships and much more, but it's Samsung that takes the most care of customers.
Whether Intel's abusing monopoly power is for others to judge. There are the European Commissioners and FTC, but there are also South Korean government and PRC government... that are much more harsh than the Western regularatory bodies, and much more biased against Intel as well. Intel and Microsoft will never get fair treatments in South Korea, but all those people bitter about Intel in California don't really understand why it's hated in some other countries. One reason's it's more profitable for governments to hate Intel, than AMD, because AMD can pay much less. Better sue the rich guys. So far, at least during the recent few years, the EU and the US governments don't seem to care much about AMD losing and sinking. Intel's not doing very well, either. It's still growing and making more processors each year, but ARM's and Samsung, and Apple are growing far faster in the CPU market. Some things will happen in the coming few years like this. AMD's right now firing its heads in Taiwan and China.
