Son processeur Core i7 est près de 40 % plus lent que celui du Dell 9510 2-en-1 équipé du même processeur. Ce déficit peut être attribué au potentiel Turbo Boost du système HP, qui a une durée de vie plus courte.

Les ordinateurs portables HP EliteBook comptent toujours parmi les meilleurs ordinateurs portables professionnels que vous pouvez trouver en termes de facilité d'entretien, de luminosité et de portabilité. Contrairement à leurs concurrents qui aiment s'essayer aux capteurs de proximité ou aux conceptions en fibre de carbone, les systèmes EliteBook se concentrent davantage sur les éléments de base que les utilisateurs souhaitent réellement, comme la RAM et le WLAN évolutifs et un écran visible en extérieur. Un aspect particulier, cependant, continue d'être bien en dessous de la moyenne.

Nous avons récemment testé le EliteBook 830 G7 équipé du dernier processeur Core i7-10810U de 10e génération et nous avons constaté que les performances multi-fil sont plus lentes que celles de tous les ordinateurs portables Core i7-10710U de notre base de données. La différence n'est pas marginale non plus puisque nous parlons d'un déficit d'environ 40 %. Même le Dell Latitude 9510 2-en-1, qui est équipé du même processeur Core i7-10810U que notre HP, est capable de surpasser l'EliteBook de plus de 55 % dans les tests CineBench.

Alors, qu'est-ce qui se passe ici ?

La principale différence réside dans la moins bonne durabilité du Turbo Boost du CPU de l'EliteBook 830 G7 par rapport à la plupart des autres ordinateurs portables équipés de CPU Core U-series. En faisant tourner Prime95 sur le HP, par exemple, son CPU passerait à 3,5 GHz pendant quelques secondes seulement avant de tomber à 1,9 GHz alors que le Latitude 9510 2-en-1 se stabiliserait à 3,2 GHz pendant bien plus d'une minute dans les mêmes conditions de test. En d'autres termes, le système Dell est capable de maintenir des fréquences d'horloge plus élevées pendant plus longtemps pour des performances plus rapides lors de charges de travail "éclatées".

Le fonctionnement en boucle du CineBench R15 xT, comme illustré ci-dessous, illustre le faible Turbo Boost du système HP. Alors qu'un ordinateur portable Core i7 Comet Lake-U sur deux dans notre base de données est capable d'obtenir d'excellents résultats au début du test en boucle, l'EliteBook 830 G7 est déjà le moins performant dès le début.

Le HP n'est en aucun cas un système lent et il excelle encore dans la plupart des autres domaines, comme son écran de 1000 bits en option, mais il ne devrait probablement pas être votre première option si la maximisation des performances du CPU est de la plus haute importance.
