### ⭐⭐⭐⭐⭐ Review
*by J***O on 1 December 2025*

Excellent processeur, stable et performant dans les applications de productivité mais aussi en jeux, bien aidé par les derniers microcodes d’Intel et les optimisations des firmware de carte mères. Bien moins energivore que les générations précédentes Raptor Lake. Contrôleur mémoire bien mieux optimisé.
