Windows 11 est officiellement sorti, mais si vous disposez d'un processeur AMD Ryzen, il est peut-\u00eatre pr\u00e9f\u00e9rable d'attendre un peu avant d'effectuer la mise \u00e0 jour. Celle-ci impacterait n\u00e9gativement les performances des puces.<\/strong><\/p>\n

\"Windows<\/p>\n

Windows 11 regorge de nouvelles fonctionnalit\u00e9s pour le gaming<\/a>, mais a malheureusement r\u00e9duit les performances de certains processeurs. Peu de temps apr\u00e8s le lancement de Windows 11 le 5 octobre dernier, AMD et Microsoft ont annonc\u00e9 que les processeurs AMD compatibles avec Windows 11 \u00ab\u00a0peuvent pr\u00e9senter des performances r\u00e9duites dans certaines applications lors de l'ex\u00e9cution de Windows 11<\/em>\u00a0\u00bb, ce qui signifie que plus d\u2019une centaine de processeurs seraient concern\u00e9s.<\/p>\n

AMD a notamment d\u00e9clar\u00e9 que sa fonction “preferred core”, qui indique au syst\u00e8me d'exploitation quel c\u0153ur de chaque CPU peut atteindre l'horloge la plus \u00e9lev\u00e9e, ne fonctionne pas correctement dans Windows 11<\/a>. Puisqu\u2019il est donc impossible pour Windows 11 de programmer correctement les threads sur le c\u0153ur le plus rapide<\/strong>, certaines \u00ab\u00a0applications sensibles aux performances d'un ou de quelques threads du CPU peuvent pr\u00e9senter des performances r\u00e9duites<\/em>\u00a0\u00bb. L'impact sur les performances serait notamment d\u00e9tectable sur les processeurs avec 8 c\u0153urs ou plus, dont le TDP est sup\u00e9rieur \u00e0 65 watts.<\/p>\n
