La RTX 5080 in 4K sale da 278 watt a 346 watt, mentre la RTX 5070 Ti in WQHD passa da 224 watt a 286 watt. RTX 5060 e RTX 5060 Ti fanno registrare aumenti pi\u00f9 contenuti, confermando un quadro abbastanza chiaro: <strong>pi\u00f9 la GPU \u00e8 potente, pi\u00f9 il costo energetico di DLSS 5 tende a crescere<\/strong>.<\/p>\n        \n        \n        \n        \n        \n      <\/section>\n    \n\n      <section class=\"fbp5-section\">\n        \n        <h2>Perch\u00e9 DLSS 5 consuma di pi\u00f9 rispetto alle <span>versioni precedenti<\/span><\/h2>\n        <p>L\u2019interpretazione tecnica \u00e8 che DLSS 5 non scarichi il lavoro soprattutto sui classici core FP32, ma sfrutti in misura maggiore i Tensor Core per l\u2019elaborazione AI. Questo approccio cambia il tipo di carico sulla scheda e pu\u00f2 spiegare perch\u00e9 i consumi aumentino proprio quando si attivano le funzioni pi\u00f9 avanzate della nuova generazione.<\/p><p>DLSS 5, presentato da Nvidia al GTC di marzo 2026 e reso disponibile a settembre con NBA 2K27, introduce un modello di <strong>neural rendering in tempo reale<\/strong> che punta ad arricchire la scena con dettagli generati dall\u2019intelligenza artificiale.

Nei casi pi\u00f9 pesanti la scheda pu\u00f2 avvicinarsi o arrivare vicino al limite dei 600 watt, un dettaglio che pesa sia sulla scelta del PSU sia sulla rumorosit\u00e0 complessiva del PC sotto carico.<\/p><p>C\u2019\u00e8 poi il fattore prezzo. La fascia alta Nvidia \u00e8 gi\u00e0 sotto pressione e la RTX 5090 viene indicata sempre pi\u00f9 vicina a <strong>5.090 dollari, circa 4.700 euro<\/strong>, con rincari medi molto distanti dal listino suggerito. In questo scenario DLSS 5 resta una novit\u00e0 tecnica di grande impatto, per\u00f2 il suo valore reale andr\u00e0 valutato anche in rapporto al consumo aggiuntivo e al costo complessivo della piattaforma.<\/p>\n        \n        \n        \n        \n        \n      <\/section>\n    \n<\/div><div class=\"rh-attribution-pills\" style=\"display:flex;gap:10px;flex-wrap:wrap;justify-content:flex-start;margin:16px 0 0\"><a href=\"https:\/\/www.ithome.com\/0\/998\/778.htm\" target=\"_blank\" rel=\"noopener\" title=\"Via: VIA\" aria-label=\"Via: VIA\" style=\"display:inline-flex;align-items:center;gap:8px;padding:10px 16px;border-radius:16px;background:linear-gradient(135deg,#fff7ed,#ffedd5);color:#c2410c;text-decoration:none;font-size:11px;font-weight:900;letter-spacing:.08em;text-transform:uppercase;border:1px solid rgba(249,115,22,.20);box-shadow:0 8px 22px rgba(249,115,22,.08)\">Via<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>I test su DLSS 5 con NBA 2K27 evidenziano consumi molto pi\u00f9 alti sulle GeForce RTX 50, con RTX 5090 come caso pi\u00f9 estremo.<\/p>\n","protected":false},"author":6,"featured_media":46585,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_exactmetrics_skip_tracking":false,"_yoast_wpseo_focuskw_text_input":"DLSS 5 consumi RTX 5090","footnotes":""},"categories":[480],"tags":[1142],"class_list":["post-46586","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","tag-videogiochi"],"blocksy_meta":{"styles_descriptor":{"styles":{"desktop":"","tablet":"","mobile":""},"google_fonts":[],"version":8}},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>DLSS 5 aumenta i consumi GPU: RTX 5090 sale fino a 561 watt in 4K<\/title>\n<meta name=\"description\" content=\"I primi test su DLSS 5 con NBA 2K27 mostrano consumi in forte crescita, soprattutto su RTX 5090.
