Selon AMD, il est encore trop t\u00f4t pour consid\u00e9rer la soi-disant \u00ab loi de Moore \u00bb comme une th\u00e9orie erron\u00e9e, car c'est pr\u00e9cis\u00e9ment les avanc\u00e9es dans le domaine de la lithographie qui ont permis \u00e0 la soci\u00e9t\u00e9 d'augmenter la performance de ses processeurs d'un facteur deux par rapport aux produits de la derni\u00e8re d\u00e9cennie au cours des deux derni\u00e8res ann\u00e9es et demie.<\/p>\n<p>Dans tous les cas, le processus technologique a contribu\u00e9 \u00e0 hauteur d'au moins 40 % \u00e0 cette augmentation des performances, comme l'indique AMD sur sa diapositive. Si l'on ajoute \u00e0 cela 20 % provenant d'optimisations au niveau du silicium, cela fait 60 % au total. Les changements au niveau de l'architecture micro ont assur\u00e9 17 % de l'augmentation totale, la gestion de la consommation d'\u00e9nergie a constitu\u00e9 15 %, et 8 % proviennent des compilateurs. Quoi qu'il en soit, sans progr\u00e8s dans le domaine de la lithographie, AMD n'aurait pas pu atteindre ces succ\u00e8s.<\/p>\n<p><center><\/center><br \/>\n<img decoding=\"async\" alt=\"AMD a d\u00e9clar\u00e9 que la lithographie \u00e9tait l&#039;un des principaux facteurs de gain de performance des processeurs modernes.\" src=\"\/wp-content\/uploads\/2019\/07\/7ac030a82b36b09d2f4a09615dba4972.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/p>\n<p>La direction d'AMD note \u00e9galement une autre tendance : plus le processus technologique est \u00ab fin \u00bb, plus le co\u00fbt de fabrication des grands cristaux sera \u00e9lev\u00e9. Par exemple, un cristal hypoth\u00e9tique d'une surface de noyau de 250 mm2 passera de 45 nm \u00e0 5 nm, ce qui le rendra cinq fois plus cher en termes de co\u00fbt unitaire par unit\u00e9 de surface. Ainsi, pour maintenir un co\u00fbt de revient \u00e9conomiquement viable, les cristaux de processeurs doivent devenir plus compacts. AMD met en \u0153uvre ce principe en passant \u00e0 l'utilisation de \u00ab chiplets \u00bb - de petits cristaux regroup\u00e9s sur un m\u00eame substrat.<\/p>\n<p><img decoding=\"async\" alt=\"AMD a d\u00e9clar\u00e9 que la lithographie \u00e9tait l&#039;un des principaux facteurs de gain de performance des processeurs modernes.\" src=\"\/wp-content\/uploads\/2019\/07\/9b848c9bf7b539b694947e4007151857.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/p>\n<p>La troisi\u00e8me diapositive, captur\u00e9e par l'objectif de la cam\u00e9ra d'un blogueur, traite de la distribution des consommateurs d'\u00e9nergie \u00e9lectrique dans les processeurs modernes \u00e0 haute int\u00e9gration.
