Courte critique du PC portable Dell Latitude 7490 (i7-8650U, écran tactile FHD)

Châssis inchangé, nouveau moteur. Le Dell Latitude 7490 de 14 pouces conserve le design du Latitude 7480 de l’an dernier, mais se dote d’un CPU de nouvelle génération quatre cœurs de la série U d’Intel. Le passage au Core i7-8650U est une évolution majeure par rapport à la puce double cœur de l’ancienne version. L’augmentation de puissance vaut-elle le passage de l’ancien au nouveau Latitude ?

* ... Moindre est la valeur, meilleures sont les performances

Temps de réponse de l'écran

Le temps de réponse d'un écran mesure la rapidité à laquelle l'écran est capable de changer une couleur pour une autre. Un temps de réponse élevé se traduit par une image floutée pour les objets en mouvement. Les joueurs bénéficieront de faibles latences d'affichage en jeu.
       Temps de réponse noir à blanc
32.4 ms ... hausse ↗ et chute ↘ combinées↗ 18.8 ms hausse
↘ 13.6 ms chute
L'écran souffre de latences très élevées, à éviter pour le jeu.
En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 240 (maximum) ms. » 84 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (25.2 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%

↘ 20.8 ms chute
L'écran souffre de latences très élevées, à éviter pour le jeu.
En comparaison, tous les appareils testés affichent entre 0.9 (minimum) et 636 (maximum) ms. » 80 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (40.3 ms) de tous les appareils testés.

Scintillement / MLI (Modulation de largeur d'impulsion)

Afin d'abaisser la luminosité de l'écran, certains ordinateurs portables font varier très rapidement le rétroéclairage entre éteint et allumé. La fréquence à laquelle le rétroéclairage s'éteint et se rallume est normalement fixée à une valeur qui permet de rendre la variation indétectable à l'œil nu? Si la fréquence est trop basse, certaines personnes peuvent être sujettes à une fatigue oculaire, des maux de tête ou même percevoir les variations.
Scintillement / MLI (Modulation de largeur d'impulsion) non décelé

En comparaison, 51 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 9533 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

- performances pas stables sur le long terme
- throttle du CPU en cas de sollicitations

En test : le Dell Latitude 7490 (Core i7-8650U, FHD, touch). Modèle de test aimablement fourni par Dell.

Dell a fait un excellent travail avec le Latitude 7490, mais avant tout parce que le travail avait déjà été fait avec le 7480 : le nouveau modèle reprend presque tout du modèle de l’an dernier. Le gros avantage du Latitude 7490 par rapport au 7480 est son processeur Intel quatre cœurs de 8e génération. Malgré la même enveloppe thermique de 15 W propre à la série U, les CPU Kaby Lake R doublent presque les performances de leur prédécesseurs de 7e génération. Le Latitude 7490 est un bon exemple des gains de puissances permis par cette nouvelle génération, mais illustre également les sacrifices qui ont dû être faits : le thermal throttling est ici un problème majeur. En cas de fortes sollicitations, le processeur est capable d’atteindre tout son potentiel, mais que sur de brefs moments.

Nous allons être francs : si vous possédez déjà un Latitude 7480, vous pouvez laisser passer le 7490. Les performances CPU supplémentaires ne seront visibles que dans les tâches ultra exigeantes, et à moins que votre cahier des charges inclut un travail sur des tableurs ultra complexes, ou d’autres tâches gourmandes en CPU, la mise à niveau ne vaut pas le coup. Mais si vous devez acheter un nouveau portable pro, ou devez remplacer maintenant une machine qui a quelques années de service derrière elle, le Latitude 7490 doit absolument être pris en compte. Dell a conçu une excellente machine qui rivalise avec les meilleurs.
