Des rumeurs avait attribu\u00e9 \u00e0 AMD l'intention de mettre en \u0153uvre la prise en charge de SMT4 dans les processeurs de serveur Milan bas\u00e9s sur l'architecture Zen 3, mais les pr\u00e9sentations officielles publi\u00e9es par la suite ont d\u00e9menti cette information.<\/p>\n<p>Mark Papermaster s'est efforc\u00e9 d'aborder la question de SMT4 de mani\u00e8re aussi abstraite que possible, soulignant son souhait de ne pas associer cette id\u00e9e aux projets existants de l'entreprise. Dans ce cadre, il a \u00e9valu\u00e9 cette fonctionnalit\u00e9 des processeurs de mani\u00e8re suffisamment objective. Selon lui, certains utilisateurs dans le segment des ordinateurs de bureau d\u00e9sactivent m\u00eame le multithreading de leurs c\u0153urs. Certaines applications b\u00e9n\u00e9ficient de cette fonctionnalit\u00e9, d'autres non. Le concept de traitement de quatre threads par un seul c\u0153ur n'est pas nouveau, il est d\u00e9j\u00e0 largement utilis\u00e9 dans le segment des serveurs. Mark a m\u00eame mentionn\u00e9 l'existence de solutions mat\u00e9rielles supportant SMT4, insinuant subtilement vers les processeurs IBM Power, qui ont acquis cette capacit\u00e9 d\u00e8s le d\u00e9but de cette d\u00e9cennie. En substance, comme le dit Mark, la l\u00e9gitimit\u00e9 de l'impl\u00e9mentation de SMT4 ne d\u00e9pend que de l'existence d'une masse critique d'applications capables de fonctionner efficacement avec elle dans un segment de march\u00e9 sp\u00e9cifique.<\/p>\n<p><center><\/p>\n<p><\/center><\/p>\n<p>\t\t\t\t<center><br \/>\n\t\t\t\t\t\t\t\t<\/center><br \/>Source : <a content=\"nofollow\"
