Nvidia a d\u00e9voil\u00e9 sa nouvelle carte graphique : la GeForce MX450. Digne h\u00e9riti\u00e8re de la gamme, elle est con\u00e7ue pour \u00e9quiper les ultra-portables et leur apporter un coup de pouce graphique, sans toutefois proposer des performances int\u00e9ressantes pour le jeu vid\u00e9o.<\/strong><\/p>\n

$\"La$ <\/p>\n

Nvidia veut continuer \u00e0 miser le march\u00e9 des ultra-portables avec sa nouvelle carte graphique GeForce MX450,<\/strong> qui vient accompagner sa MX350 pr\u00e9sent\u00e9e il y a quelques mois seulement. Une carte graphique peu puissante, mais qui n\u2019est pas con\u00e7ue pour l\u2019\u00eatre.<\/p>\n

Nvidia donne peu de d\u00e9tails<\/strong> sur sa MX450, et il faudra l\u2019avoir en main pour juger de ses performances (forc\u00e9ment moindre qu\u2019un GPU classique). Tout juste sait-on qu\u2019elle sera compatible avec l\u2019interface m\u00e9moire GDRR6 (une premi\u00e8re pour la gamme) et PCI Express 4.0. Elle est \u00e9galement compatible avec la technologie Optimus du constructeur, qui permet au PC de jongler automatiquement entre l'eGPU et le GPU pour garantir une plus grande autonomie. Nul doute que le gain de puissance sera minime et que cette carte n\u2019est qu\u2019une grosse mise \u00e0 jour de la MX350.<\/p>\n

Cette carte graphique MX450 veut suppl\u00e9er le traditionnel eGPU<\/strong>, carte graphique int\u00e9gr\u00e9e directement dans le processeur (comme les Intel HD). AMD propose de son c\u00f4t\u00e9 sa solution Vega. C'est un vrai plus pour les ordinateurs \u00e9quip\u00e9s par rapport \u00e0 un simple eGPU.<\/p>\n
