Nvidia lancera prochainement de nouvelles cartes graphiques, a priori des cartes sous le nom GeForce RTX 50 series et sous le nom de code “Blackwell”. Ces GPU de nouvelle g\u00e9n\u00e9ration int\u00e9greront la m\u00e9moire GDDR7 de Samsung, promettant des performances largement sup\u00e9rieures aux cartes RTX 40 series<\/a> actuelles. Aussi, on note selon des leakers, une augmentation notable de la consommation \u00e9nerg\u00e9tique maximale de ces cartes. Ces informations sont toutefois \u00e0 prendre au conditionnel, Nvidia n’ayant pour l’instant rien annonc\u00e9 officiellement.<\/p>\n\n\n\n

De la VRAM GDDR7 sign\u00e9e Samsung<\/h2>\n\n\n\n

La s\u00e9rie RTX 50 utiliserait la m\u00e9moire GDDR7 de Samsung, offrant des vitesses de transfert de donn\u00e9es atteignant 32 Gbps. Cette avanc\u00e9e repr\u00e9sente une augmentation significative par rapport \u00e0 la GDDR6, qui plafonnait \u00e0 24 Gbps. Gr\u00e2ce \u00e0 l’utilisation de la modulation d’amplitude d’impulsion 3 (PAM3), la GDDR7 assure une transmission de donn\u00e9es plus efficace, am\u00e9liorant ainsi les performances globales des GPU.<\/p>\n\n\n\n

\"m\u00e9moire<\/figure>\n\n\n\n

L’architecture Blackwell de Nvidia est con\u00e7ue pour les applications de calcul intensif et les jeux vid\u00e9os. Fabriqu\u00e9e sur le n\u0153ud personnalis\u00e9 4NP de TSMC<\/a>, une am\u00e9lioration du 4N utilis\u00e9 pour les architectures Hopper et Ada Lovelace<\/a>, Blackwell promet des gains en efficacit\u00e9 \u00e9nerg\u00e9tique et en performance. Les GPU bas\u00e9s sur Blackwell d\u00e9voileront la cinqui\u00e8me g\u00e9n\u00e9ration de c\u0153urs Tensor, optimis\u00e9s pour les calculs d’intelligence artificielle.<\/p>\n\n\n\n

Date de disponibilit\u00e9<\/h2>\n\n\n\n

Selon les informations disponibles, Nvidia pourrait annoncer les RTX 50 series lors du CES 2025, pr\u00e9vu en janvier. Cependant, un constructeur dont nous tairons le nom, nous a indiqu\u00e9 en off, que ce lancement pourrait \u00eatre pr\u00e9vu plut\u00f4t pour le mois de f\u00e9vrier. Les mod\u00e8les haut de gamme, tels que le RTX 5090, devraient \u00eatre \u00e9quip\u00e9s de 32 Go de m\u00e9moire GDDR7, mais n\u00e9cessiter d’une puissance d’environ de 600 watts.<\/p>\n\n\n\n

Comme lors des pr\u00e9c\u00e9dents lancements, les cartes plus accessibles et moins performantes donc, comme la RTS 5060 ou la RTX 5070, si tant est qu’elles existeront, seraient pr\u00e9sent\u00e9es ult\u00e9rieurement, si l’on en croit les derniers lancements du constructeur.<\/p>\n","protected":false},"excerpt":{"rendered":"
