Mi-juin, certains ont soup\u00e7onn\u00e9 AMD d\u2019avoir repouss\u00e9 ses Ryzen 4000, nom de code Vermeer, \u00e0 2021<\/a>, en raison du succ\u00e8s des Ryzen 3000 et du lancement des Ryzen 3000XT<\/a>. Heureusement, la soci\u00e9t\u00e9 a rapidement d\u00e9menti cette information et a rassur\u00e9 tout le monde : les Ryzen 4000, sous architecture Zen3, arriveront bien avant la fin d\u2019ann\u00e9e. Ces derniers auraient atteint le stade B0, synonyme de versions finalis\u00e9es et pr\u00eates pour la production de masse.<\/p>\n\n\n\n

\"Image<\/a><\/figure><\/div>\n\n\n\n

C\u2019est que ce rapporte Igor Wallossek<\/a>. Celui-ci ne sait pas quand la production d\u00e9butera pr\u00e9cis\u00e9ment, mais il indique que le stade B0 donne de la marge \u00e0 AMD pour choisir la date de lancement.
<\/p>\n\n\n\n

AMD a am\u00e9lior\u00e9 par 31,7 l\u2019efficacit\u00e9 \u00e9nerg\u00e9tique de ses processeurs mobiles en 6 ans<\/strong><\/a><\/p>\n\n\n\n

Le champ libre pour la fin d’ann\u00e9e<\/h2>\n\n\n\n

Il faut en effet 3-4 mois pour fabriquer suffisamment de processeurs. Rappelons que c\u2019est le fondeur ta\u00efwanais TSMC qui se charge de la production en 7 nm pour AMD. Autant dire que l\u2019entreprise dirig\u00e9e par Lisa Su a le champ libre d\u2019ici la fin d\u2019ann\u00e9e, surtout que du c\u00f4t\u00e9 d\u2019Intel, sur le march\u00e9 des processeurs de bureau, il faudra tenir avec les Comet Lake-S puisque les Rocket Lake-S n\u2019arriveront pas avant 2021<\/a>.<\/p>\n\n\n\n

Du Vega 20 pour les APU Cezanne<\/h2>\n\n\n\n

Igor Wallossek communique \u00e9galement de pr\u00e9cieuses informations sur les APU Ryzen 5000, Cezanne, qui arriveront apr\u00e8s les APU Ryzen 4000 Renoir. AMD conservera la division H (haute performance) \/ U (faible consommation). Surtout, contrairement \u00e0 ce qu\u2019on supposait jusqu\u2019ici, les APU Cezanne ne b\u00e9n\u00e9ficieront pas d\u2019une solution graphique int\u00e9gr\u00e9e Navi RDNA2 mais simplement Vega 20. Les puces Van Gogh, pour PC portables, profiteront pour leur part d\u2019une solution graphique Navi 21.<\/p>\n\n\n\n

\"Image<\/a><\/figure><\/div>\n\n\n\n

Sur les secteur des APU pour PC fixes, il faudrait patienter jusqu\u2019\u00e0 la gamme Rembrandt, laquelle succ\u00e9dera \u00e0 Cezanne<\/a>, pour voir une solution graphique int\u00e9gr\u00e9e Navi RDNA2. Ainsi, AMD passerait directement de Vega \u00e0 Navi RDNA2 pour cette gamme de produits.<\/p>\n","protected":false},"excerpt":{"rendered":"
