Intel Core i7-7700K

Intel i7-7700K

L'Intel Core i7-7700K est un processeur quad-core relativement rapide destiné aux ordinateurs portables. Lancé en Janvier 2017 en tant que processeur grand public H le plus rapide (toutes gammes confondues), il est basé sur l'architecture Kaby Lake. Chaque cœur bénéficie de l’HyperThreading et offre une fréquence entre 4.2 et 4.5 GHz. Une des caractéristiques notables est l'intégration d'une carte graphique intégrée HD Graphics 630 et d'un contrôleur mémoire bicanal DDR3L-1600/DDR4-2400. La gravure selon une lithographie d'une finesse de 14 nm fait appel à la technologie FinFET.

Architecture

Dans les faits, Intel a tout simplement réutilisé la même microarchitecture que sur Skylake, les performances par cycle d’horloge n’ont que peu varier si ce n’est pas du tout. Le fondeur a simplement revu la technologie Speed Shift pour un ajustement plus rapide de la tension et de la fréquence. La gravure en 14nm a elle aussi été légèrement modifiée et permet d’atteindre des fréquences plus élevées tout en gagnant en efficience énergétique.

Performances

Grâce à ses 200 MHz de plus sur sa fréquence nominale et ses 300 MHz additionnels sur sa fréquence Boost, le i7-7700K est devant l'ancien Core i7-6700K d'une poignée de pourcentage (ratio performance par cycle d'horloge similaire). Il s'agit d'un quad-core très rapide, qui se sentira à l'aise dans toutes les tâches, même les plus gourmandes.

Circuit graphique

La puce graphique intégrée, la HD Graphics 630, possède 24 Unités d'exécution (EU) cadencées de 350 MHz à 1150 MHz. Les performances dépendent fortement de la configuration de la mémoire système. En combinaison de mémoire DDR4-2133 en bicanal, les performances devraient de l’ordre d’une Nvidia GeForce 920M.

Contrairement à Skylake, Kaby Lake prend dorénavant en charge le décodage matériel H.265/HEVC Main 10 avec une profondeur des couleurs à 10-bit, ainsi que le codec VP9 de Google. Les dual-cores Kaby Lake annoncés aussi en Janvier devraient aussi embarquer le support du HDCP 2.2.

Consommation énergétique

Le processeur est gravé selon un procédé en 14nm FinFET qui a été amélioré à en croire Intel. Bien que l’efficience énergétique ait été améliorée, Intel indique toujours un TDP de 95 Watts, soit bien plus que les 45 Watts donnés sur les processeurs Kaby Lake H mobiles.
