nice to hear, amd has something new, but in the end, i would not buy bleeding edge stuff, just because marketing tells me to, but because i have a certain budget, and need “stuff”.

history blah, tldr.
just a bit of history, because i find it interesting to remember both companies closely related hate-love-relationship, and just find it interesting (and re-researched it just so i dont share bs)
the reason intel had to share technology with amd in the early 80s, was because of ibm’s policy of having to have two sources for the processors they wanted to use in products, even if they had decided to use intels 8086 chips, which came in 81 with the ibm pc, it could not be produced by intel alone. they forced intel into a deal with amd, and until the 90s, intel delayed it but finally had to agree on sharing all architectures until the pentium era (not cool intel! not cool!). only since then amd started to have success with their own architectures, until then, their biggest strength was, that it was a very dedicated company, who pioneered in giving shares to their workers (cool amd!) and also had some experience with x86, as they had already reverse engineered the 8080 (not so cool amd…, but impressive.)

the reason why intel had a quasi monopoly is, because it was founded in the late 60s by the guy who co-invented the integrated circuit itself, especially based on silicon chips, robert noyce, and therefore a huge advantage in knowledge how to create them. besides that, moores law gave them a healthy “self measurement”, ensuring they actually innovate even without competitors, which probably lead to them being elected by ibm to start the “pc”. from then on, it was more a war of architecture, less of cpu power until the pentium (80586) era.

so in the end, we can thank ibm and legal trust laws for intel not having a monopoly right now. both companies however came from the same source, as noyce and moore (the one with the law) had both worked in fairchild semiconductors before they left to create intel, same as the group of engineers who founded AMD a year later with the help of jerry sanders. both were already players, when the game started.
there were however many, many other players in this game, who were real enemies of intel and amd together, especially motorola, whose risc processors outshined intel in floating point operations - and who was in the game until apple decided to go x86 aswell, basicly making intel cpu chipset the norm. so i do not see them as arch enemies, more like two giants who tolerate each other, because they need each other to survive and thrive, and basicly innovate on the same architectural principles. success is just a question, whether they have the correct tools for the current need. both cant make magicly create something superb that is really cheaper than the other can.
In architecture, ARM e.g. still is used a lot aswell, as it is a risc processor, reducing power need, so also especially in supercomputing, raspberry pis, or handhelds, mainly in linux and apple land, and microsoft has announced, that win10 will get to arm aswell. That might trigger events in the aftermath, that will change computing a lot more, than ryzen ”). (love the thread title btw.)
