D\u00e9sormais, on s&#8217;attend plut\u00f4t \u00e0 ce que la RTX 4080 affiche un TBP de 320 watts seulement, et de 285 watts pour la RTX 4070. De plus, on apprend que la RTX 4070 afficherait des fr\u00e9quences GPU de 2310 MHz, avec un Boost \u00e0 2610 MHz et une fr\u00e9quence maximale au del\u00e0 des 2,8 GHz. Les autres caract\u00e9ristiques (nombres de coeurs et bus\/vitesse m\u00e9moire) suppos\u00e9es restent en revanche inchang\u00e9es.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"responsive-container\"><blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">There is an update of RTX 4070. <br>PG141-SKU331<br>7680FP32<br>12G 21Gbps GDDR6X<br>300W<br>TSE &gt;11000<\/p>&mdash; kopite7kimi (@kopite7kimi) <a href=\"https:\/\/twitter.com\/kopite7kimi\/status\/1555053945151975425?ref_src=twsrc%5Etfw\">August 4, 2022<\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/div>\n<\/div><\/figure>\n\n\n\n<p>Un autre leaker rapporte qu&#8217;un mod\u00e8le suppl\u00e9mentaire de carte graphique &#8220;Ada Lovelace&#8221;, avec 20 Go de m\u00e9moire GDDR6X, serait dans les cartons de NVIDIA.
