It's a combination of architecture and process that is helping AMD and hurting Intel right now. I don't think it's luck: Intel got complacent and AMD got hungry. We're seeing the effects of 10 years of that on both companies today. While it's possible there is a pile of undiscovered issues that will exclusively impact AMD's processor line, I doubt that's the going to be the case. Intel's issues are far bigger than just x86. They've had major screw-ups and public exits from multiple markets including: mobile, IoT, wireless radios. They appear to be having execution issues generally and their architecture issues started 20+ years ago. This is what technical debt looks like when the bill comes due.
