this is a potentially ridiculous article seriously it is a potentially ridiculous article and mislead readers to comprehend the word x for the following reasons should sort amd or intel implementations as x generally x was used to point all the processors compatible with ia isa might or might name themselves with such as cyrix x intel pentium and so on amd 's long mode is devised by amd rather than intel so how can one sort them together nowadays software labeled themselves as x are ia compatible software and use x or x differentiating with it so this article confuses reader getting in touch with this word generations what is the th generation x processor who invented this kinda processors amd k just says that it succeeds amd k rather than saying it is the th x processor and i've never heard intel call their x processors exceeding the th generation and one thing should never be denied the first generation of itanium processor says its family model number as which might potentially imply that itanium might be the th x processor succeeding pentium iii but none confirmed this so take turn back the transmeta's crusoe and efficeon if the morph firmed on the system board implements x decoder call themselves as x processors then if put the same processor on another board implementing powerpc decoder then it would be the powerpc processor at this situation what kind of processor is it ridiculous what's more for what sort it as the th th generation x who is another jane austen making up another northanger abbey x is one architecture isa name what such a ridiculous thing that i've ever heard on earth x is used to referring the processor a kind or series of processors rather than an architecture if it were the name of an architecture then in this logic way intel is one of the implementation of this architecture
