Do you know there were another processor in the competition than intel (the x86 holder) and AMD?. Cyrix was in the 80’s and 90’s a real PITA to intel. Unfortunately, they were behind intel because intel was in the design part, they seemed to be always cloning intel instead of creating their new tech.
I don’t know what was rally the difference that made Cyrix to die and AMD to be what it is now.
PS. I still remember working with some AMD Geode chips (which were Cyrix before AMD bought them from National Semiconductors).
