It really depends on your goals, your use case. In begin of AMD64 a lot of Windows software was single threaded 32 bit still, while on Debian with APT you had a working 64 bit environment. It was mostly userland which could not handle the amount of max cores found in even consumer grade multicore AMD64. Even recently many games did not take advantage of multiple cores, while AMD has been strong performance wise multiple cores, Intel was best single core until Zen 3 recently. Windows would be unable to perform well (use max cores) on AMD64 by AMD. You can see it now too. Intel gets slight performance boost with Windows 11 compared to 10 while AMD loses performance. Which AMD said they will address in October.
