Nvidia annonce le Tegra X1.<\/figcaption><\/figure>\n
Annonc\u00e9 comme 50%\u00a0plus puissant que le Tegra K1<\/strong>, ce nouveau processeur 64 Bit<\/b> se compose de quatre c\u0153urs A53 et quatre c\u0153urs A57 et surtout d'un GPU Maxwell de 256 c\u0153urs qui devrait lui permettre d'atteindre des performances graphiques comparables \u00e0 celles d'un PC.<\/p>\n
V\u00e9ritable monstre de puissance (plus d'un Teraflop<\/strong>) en perspective, ce nouveau processeur Tegra X1 supporte DirectX 12 et OpenGL 4.5 ainsi que la lecture et l'enregistrement de vid\u00e9os en 4K \u00e0 raison de 60 images par seconde.<\/p>\n
<\/p>\n
Seul hic, en d\u00e9pit de l'\u00e9tendue de ses performances, on ne pourra pas esp\u00e9rer le retrouver sur de futures g\u00e9n\u00e9rations de smartphones et de tablettes pour la simple et bonne raison qu'il est trop \u00e9nergivore<\/b> pour donner pleinement satisfaction sur ce type d'appareils.<\/p>\n
Avec son enveloppe thermique de 10 Watts, le X1 consomme environ deux fois plus d'\u00e9nergie que le Tegra K1, en d\u00e9pit des efforts r\u00e9alis\u00e9s pour am\u00e9liorer son efficacit\u00e9 \u00e9nerg\u00e9tique gr\u00e2ce \u00e0 la gravure en 20 nm.<\/p>\n
S'il est clair que le processeur Nvidia Tegra X1 est trop peu \u00e9conome pour avoir sa place sur le march\u00e9 des terminaux mobiles, alors \u00e0 quels types d'appareils se destine-t-il\u00a0? Les consoles de jeux et les v\u00e9hicules connect\u00e9s<\/b> sous Android Auto, autrement dit des appareils o\u00f9 le facteur \u00e9nerg\u00e9tique n'est plus un probl\u00e8me, ceux-ci pouvant disposer d'une alimentation constante.<\/p>\n
Afin de d\u00e9montrer l'\u00e9tendue des performances graphiques de sa derni\u00e8re puce, Nvidia en a fait, hier soir, une d\u00e9monstration \u00e0 partir de la d\u00e9mo d'Elemental (Epic Games) qui utilise justement le moteur Unreal Engine 4<\/b>. Pour l'heure, c'est avant vers les voitures que Nvidia semble d\u00e9cid\u00e9 \u00e0 destiner cette nouvelle puce qui semble \u00e9galement avoir tout \u00e0 fait sa place sur les places sur les consoles de jeux sous Android<\/strong>. Pourquoi pas sur une prochaine g\u00e9n\u00e9ration de la Shield\u00a0?<\/p>\n","protected":false},"excerpt":{"rendered":"C’est \u00e0 l’occasion du CES 2015 qui ouvrira ses portes d\u00e8s demain \u00e0 Las Vegas que Nvidia a choisi de lever le voile sur son dernier processeur le Tegra X1.
