Frequently asked questions

Quelle carte est plus rapide : RTX 4070 ou RTX 3070 ?

En raster pur, la RTX 4070 devance d'environ **8–12 %** en 1080p (Cyberpunk : ~106 vs ~97 FPS) et **~10–15 %** en 1440p. Avec DLSS 3 Frame Generation, l'écart perçu peut être plus large sur la 4070.

Vaut-il le coup de passer de RTX 3070 à RTX 4070 en 2026 ?

Oui si tu vises le **1440p**, le **stream NVENC** ou les **12 Go VRAM**. Non si tu es satisfait en **1080p 144 Hz** — l'upgrade raster seul ne justifie pas **~150–180 €**.

RTX 4070 ou RTX 3070 pour du 1440p ?

La **RTX 4070** est le choix confortable en 1440p high/ultra. La **3070** reste jouable avec DLSS Quality, mais les **8 Go** limitent plus vite sur les AAA 2025–2026.

12 Go vs 8 Go VRAM : est-ce décisif ?

En **1440p ultra** et jeux texture-heavy (Hogwarts Legacy, TLOU Part I), oui — la 4070 a plus de marge. En **1080p high**, la 3070 suffit encore pour la majorité du catalogue.

Quelle alimentation pour RTX 4070 et RTX 3070 ?

Un **550–650 W 80+ Bronze/Gold** avec Ryzen 5 / Core i5 convient aux deux. La 4070 consomme ~200 W, la 3070 ~220 W — aucune n'exige un bloc 850 W.

Quels prix en France en juillet 2026 ?

RTX 4070 **380–440 €** neuve (LDLC, TopAchat, Amazon). RTX 3070 **220–260 €** occasion contrôlée sur Leboncoin. Au-delà de ~280 € occasion, compare une 4070 neuve.

La RTX 3070 est-elle encore une bonne carte en 2026 ?

Oui pour **1080p** et e-sport à bon prix d'occasion. Pour un **achat neuf** en 2026, la 4070 (ou une RX 7800 XT) offre plus de marge long terme — surtout en 1440p.

DLSS 3 change-t-il la donne face à une 3070 ?

Souvent oui sur les jeux compatibles (Cyberpunk, Hogwarts Legacy, Fortnite) : seule la **4070** propose Frame Generation. La 3070 reste limitée au DLSS 2 classique.
