C\u2019est la raison pour laquelle les fonctionnalit\u00e9s susmentionn\u00e9es, de s\u00e9lection du meilleur CCD selon les charges de travail, ne concernent que les Ryzen 9.<\/p>\n\n\n\n<p>\u00c0 propos de la r\u00e9partition des c\u0153urs CPU via les chiplets, elle est simple en principe&nbsp;: un CCD pour les processeurs \u00e0 6 et 8 c\u0153urs (Ryzen 5 et Ryzen 7), deux CCD pour les processeurs \u00e0 12 et 16 c\u0153urs (Ryzen 9). Il arrive toutefois <a href=\"https:\/\/www.tomshardware.fr\/un-premier-ryzen-5-7600x-a-deux-ccd-deniche\/\">qu\u2019AMD commercialise des Ryzen 5 et 7 avec deux CCD.<\/a> Cela arrive lorsqu\u2019une partie des c\u0153urs CPU d\u2019un CCD sont d\u00e9fectueux.<\/p>\n\n\n\n<p>Bref, les Ryzen 9 imposent dans tous les cas deux CCD. AMD a toutefois deux options&nbsp;: un CCD \u00e0 8 c\u0153urs CPU activ\u00e9s et un autre \u00e0 4 c\u0153urs, ou deux CCD \u00e0 6 c\u0153urs activ\u00e9s. L\u2019entreprise a donc choisi cette seconde option pour le Ryzen 9 7900X3D.<\/p>\n\n\n\n<p>Seulement vous l&#8217;aurez compris, ce choix a son importance dans la mise en \u0153uvre des fonctionnalit\u00e9s \u00e9voqu\u00e9es ci-dessus : il implique que seuls 6 c\u0153urs CPU ont un acc\u00e8s direct au cache L3 suppl\u00e9mentaire. L&#8217;inconnue est la latence qu&#8217;induit l&#8217;acc\u00e8s aux donn\u00e9es du cache 3D par les c\u0153urs de l&#8217;autre CCD. Or, nous supposons que si AMD a pris le temps de d\u00e9velopper des fonctionnalit\u00e9s qui permettent au syst\u00e8me d&#8217;exploitation de &#8220;switcher&#8221; entre les deux CCD, celle-ci n&#8217;est pas marginale.<\/p>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<p><strong>A lire aussi, les derni\u00e8res actualit\u00e9s d\u00e9di\u00e9es aux processeurs AMD Ryzen 7000 en socket AM5 :<\/strong><\/p>\n\n\n\n    <ul>\n                    <li><a href=\"https:\/\/www.tomshardware.fr\/attention-aux-ryzen-7-7800x3d-doccasion-ce-modele-factice-est-plus-vrai-que-nature\/\">Attention aux Ryzen 7 7800X3D d&#8217;occasion : ce mod\u00e8le factice est plus vrai que nature<\/a><\/li>\n                    <li><a href=\"https:\/\/www.tomshardware.fr\/les-ryzen-deviennent-plus-performants-sous-windows-11-23h2-les-modeles-zen-3-a-zen-5-concernes\/\">Les Ryzen deviennent plus performants sous Windows 11 23H2, les mod\u00e8les Zen 3 \u00e0 Zen 5 concern\u00e9s<\/a><\/li>\n                    <li><a href=\"https:\/\/www.tomshardware.fr\/des-millions-de-systemes-amd-menaces-cette-faille-permet-de-voler-vos-donnees\/\">Des millions de PC AMD vuln\u00e9rables, cette faille vieille de 10 ans met vos donn\u00e9es en danger<\/a><\/li>\n                    <li><a href=\"https:\/\/www.tomshardware.fr\/les-nouveaux-ryzen-xt-repousses-lancement-coordonne-ou-defaut-de-derniere-minute\/\">Les nouveaux Ryzen XT repouss\u00e9s, lancement coordonn\u00e9 ou d\u00e9faut de derni\u00e8re minute\u00a0?\u00a0[MAJ]<\/a><\/li>\n            <\/ul>\n\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pas-d-echantillon-de-ryzen-9-7900x3d-pour-les-tests\">Pas d&#8217;\u00e9chantillon de Ryzen 9 7900X3D pour les tests<\/h2>\n\n\n\n<p>Pour finir, vous aurez aussi constat\u00e9 en parcourant la presse que la quasi int\u00e9gralit\u00e9 des tests publi\u00e9s hier portent sur le Ryzen 9 7950X3D.
