Cependant, les meilleures sont souvent les plus ch\u00e8res et peuvent atteindre facilement le millier d&#8217;euros. C&#8217;est le cas notamment de NVIDIA et de sa <a href=\"https:\/\/www.tomshardware.fr\/test-nvidia-geforce-rtx-4090-carte-graphique-createurs-jeux-performances-consommation\/\">GeForce RTX 4090<\/a>, vendue entre 2000 et 2200 euros.<\/p>\n\n\n\n<p>Heureusement, certains constructeurs cherchent un <strong>juste milieu entre performances et prix<\/strong> abordable, \u00e0 l&#8217;image d&#8217;AMD. Si la Radeon RX 7900 XTX est vendue ch\u00e8re, le constructeur am\u00e9ricain tente \u00e9galement de proposer des <strong>segments d&#8217;entr\u00e9e et de milieu de gamme<\/strong>. Notamment en basant ses cartes graphiques sur des GPU plus abordables.<\/p>\n\n\n\n<p>Selon les derni\u00e8res informations rapport\u00e9es par le Youtuber Moore&#8217;s Law is Dead, AMD serait en train de pr\u00e9parer deux nouveaux <strong>chipsets graphiques : les Navi 48 et 44<\/strong>. Ces GPU seraient <strong>bas\u00e9s sur l&#8217;architecture RDNA4<\/strong> et pourraient permettre \u00e0 AMD de rivaliser avec certaines cartes graphiques de NVIDIA.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"responsive-container embed-youtube-com\"><iframe title=\"AMD Navi 48 Leak: RDNA 4 Performance, Die Size, Release Date Targets\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/Hbx4AUcQ5do?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-que-valent-les-chipset-graphiques-navi-44-et-48\">Que valent les chipset graphiques Navi 44 et 48 ?<\/h2>\n\n\n\n<p>Le Navi 44, grav\u00e9 par TSMC en 5nm et utilisant <a href=\"https:\/\/www.tomshardware.fr\/tsmc-ajoute-un-noeud-de-gravure-le-n4p\/\">le n\u0153ud de gravure N4P<\/a>, serait une puce monolithique RDNA 4 cadenc\u00e9e<strong> entre 3,0 GHz et 3,3 GHz<\/strong>. En revanche \u00e9tant bas\u00e9 sur des \u00e9chantillons, cette cadence ne <strong>refl\u00e8terait pas celle du chipset final<\/strong>. Les sp\u00e9cifications techniques r\u00e9v\u00e8lent une taille de puce estim\u00e9e \u00e0 210 mm\u00b2.<strong> <\/strong>En ce qui concerne le Navi 48, la taille de la puce serait, elle, comprise entre 300 et 350 mm\u00b2.<\/p>\n\n\n\n<p>AMD envisage sur ses chipsets Navi 41 et 42 (plus haut de gamme) un contr\u00f4leur m\u00e9moire c<strong>ompatible avec la GDDR7<\/strong>. Cependant, ce ne serait <strong>pas le cas pour les Navi 44 et 48<\/strong>. En effet, l\u2019entreprise <strong>conserverait la GDDR6<\/strong> pour ses cartes graphiques bas\u00e9es sur ces GPU inf\u00e9rieurs en gamme.<\/p>\n\n\n\n<p>Les performances en rasterisation du Navi 44 lui <strong>permettrait de se mettre au niveau<\/strong> des cartes <strong>RX 7600 XT et 7800 XT. <\/strong>Le chipset graphique Navi 48, quant \u00e0 lui, se placerait entre les Radeon<a href=\"https:\/\/www.tomshardware.fr\/test-amd-radeon-7900-xt-7800-7700-7600-7500-rdna3-caracteristiques-performances-prix\/\"> RX 7900 XT et 7900 XTX<\/a>.<\/p>\n\n\n\n<p>Il faut noter que la nomenclature actuelle des chipsets laisse planer le doute sur la <strong>v\u00e9racit\u00e9 de ces informations<\/strong>. En effet, habituellement, <strong>moins le nombre est grand<\/strong>, plus les <strong>chipsets montent en gamme<\/strong>.
