Fin mars, le DigiTimes indiquait que TSMC \u00e9tait en avance sur sa feuille de route pour le 4 nm et d\u00e9buterait la production de masse au cours du quatri\u00e8me trimestre 2021. Un communiqu\u00e9 officiel du fondeur confirme les progr\u00e8s et annonce un d\u00e9but de la production de test d\u00e8s le troisi\u00e8me trimestre ; auparavant, TSMC pensait atteindre cette phase le trimestre suivant.<\/p>\n\n\n\n

Sur le papier, le 4 nm est plus une am\u00e9lioration du 5 nm plut\u00f4t qu\u2019un nouveau n\u0153ud de gravure important. \u00c0 ce titre, il int\u00e8gre la grande famille du N5, qui regroupe \u00e9galement le 5 nm “classique”, le 5 nm+ (N5P), et conviendra \u00e0 des produits initialement con\u00e7us en 5 nm. TSMC mentionne une am\u00e9lioration des performances, de l’efficacit\u00e9 \u00e9nerg\u00e9tique et la densit\u00e9 des transistors mais ne chiffre pas les gains escompt\u00e9s.<\/p>\n\n\n\n

TSMC est aussi un client d\u2019AMD : le fondeur utilise des processeurs EPYC \u00e0 diff\u00e9rents niveaux<\/a><\/strong><\/p>\n\n\n\n

Le 3 nm en 2022<\/h2>\n\n\n\n

Dans son communiqu\u00e9, le fondeur ta\u00efwanais confirme aussi que la production de masse en 3 nm d\u00e9butera au cours du second semestre 2022<\/a>. Contrairement au 4 nm, le 3 nm repr\u00e9sentera un v\u00e9ritable saut g\u00e9n\u00e9rationnel. Sans doute le dernier n\u0153ud bas\u00e9 sur des transistors FinFET, il am\u00e9liore les performances de 15 % ou r\u00e9duit la consommation de 30 % par rapport au N5 selon TSMC, et offre une densit\u00e9 logique 70 % sup\u00e9rieure.<\/p>\n\n\n\n

Enfin, en ce qui concerne les produits qui b\u00e9n\u00e9ficieront de ces gravures, outre les puces d\u2019Apple, il y aura les prochaines g\u00e9n\u00e9rations de Ryzen<\/a>. L\u2019architecture Zen 4 devrait impliquer un n\u0153ud de gravure en 5 nm ; l\u2019architecture Zen 5, un n\u0153ud de gravure en 3 nm.<\/p>\n\n\n\n
