Le Nvidia A100, premier GPU bas\u00e9 sur l'architecture Ampere vient de subir son premier Benchmark sur la plateforme OctaneBench. C'est sans surprise le plus rapide des GPU con\u00e7us \u00e0 ce jour. La carte test\u00e9e devance de 45 points la Titan V qui d\u00e9tenait le pr\u00e9c\u00e9dent record. La RTX 2080 Ti quant \u00e0 elle est distanc\u00e9e de 144 points, soit d'environ 48%. Cette comparaison est purement indicative, les deux cartes graphiques ne jouant pas vraiment dans la m\u00eame cat\u00e9gorie.<\/strong><\/p>\n

\"Nvidia<\/p>\n

En mai dernier, Nvidia pr\u00e9sentait l'A100, le premier GPU bas\u00e9 sur l'architecture Ampere<\/a>. La firme annon\u00e7ait alors des performances jusqu'\u00e0 20 fois sup\u00e9rieures \u00e0 celles du GPU V100 destin\u00e9 au segment professionnel. Deux mois se sont \u00e9coul\u00e9s depuis l'annonce et voici enfin un premier Benchmark du GPU <\/strong>qui nous offre un aper\u00e7u de ses performances. Le test a \u00e9t\u00e9 r\u00e9alis\u00e9 sur la plateforme OctaneBench, un Benchmark con\u00e7u pour tester les performances dans OctaneRender, un moteur de rendu 3D.<\/p>\n

La carte a obtenu un score de 446 points<\/strong> et arrache la t\u00eate du classement \u00e0 la Nvidia Titan V qui enregistre une moyenne de 401 points. Cela repr\u00e9sente une progression de 11,2% .\u00a0La GeForce RTX 2080 Ti quant \u00e0 elle est quatorzi\u00e8me du classement avec 302 points<\/strong>.\u00a0L'A100 est presque 48% plus rapide que la carte Turing. Une comparaison plus juste mettrait en confrontation le GPU avec le Tesla V100 qui a affich\u00e9 371 points. L'A100 est donc 18% plus rapide que son v\u00e9ritale pr\u00e9d\u00e9cesseur.<\/p>\n
