Le Razer Core V2 et le Blade Stealth, un duo parfait.
Le Razer Core V2 et le Blade Stealth, un duo parfait.

Selon toute vraisemblance, le Blade Stealth ne s’adresse qu’à une cible restreinte. Même si Razer est avant tout associé aux portables pour joueurs, et donne l’impression qu’il a conçu un portable de jeu, le Blade Stealth seul n’est en fait pas assez puissant avec sa puce Intel UHD 620 Graphics. La plupart des jeux actuels qui ont un besoin d’un minimum de ressources graphiques pourront tourner au mieux à un niveau de détails moyen. Et l’appareil ne contentera pas non plus les autres clients potentiels, qui ont besoin de leur machine au bureau et en déplacement, à cause de sa mauvaise autonomie, de l’absence d’un écran mat, et de la pauvreté de sa connectique.

"Portable le jour, ordinateur de jeu la nuit." Razer était au courant de l’équilibre nécessaire à trouver pour satisfaire deux types de clients différents. Le Blade Stealth est intéressant pour les joueurs, s'il est combiné avec le Razer Core V2.

Le Razer Core équipé d’une carte graphique dédiée remplace la UHD 620 interne, via la connexion Thunderbolt 3, permettant des performances excellentes dans tous les jeux. Nous l’avons déjà testé de manière approfondie. Par exemple, avec Resident Evil 7 à un niveau de détail élevé (1 920 x 1 080 avec AF, FXAA et TAA), le Razer Blade Stealth n’atteint que 10 FPS avec la UHD 620, ce qui est injouable, tandis que le Razer Core V2 avec une Nvidia GeForce GTX 1050 atteint 56 FPS, soit une hausse de 82 %. Les 40 Gbit/s du Thunderbolt ne ralentissent pas vraiment les choses ici, la même carte graphique pouvant atteindre environ 59 FPS avec un PC de bureau. Nous allons bientôt publier les tests du Razer Core V2 avec le Blade Stealth, avec tous les résultats de nos benchmarks avec les jeux actuels, pour comparer les différences de performances entre une solution interne et une externe.
