Courte critique du Lenovo ThinkPad L490 (i5-8265U, UHD 620, FHD) : Whiskey Lake décevant dans ce portable de bureau

Christian Hintze, 👁 Andreas Osthoff (traduit par Prévots), 09/09/2019

Whiskey Lake à la traîne. Nous avons testé le ThinkPad L480 (87 %) il y a environ 1 an, et nous n’avions que l’écran trop sombre à critiquer. Lenovo a changé l’écran du successeur, et a mis à jour son processeur. Néanmoins, "nouveau" ne signifie pas toujours "meilleur", comme le montre notre test du L490.

* ... 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
26.4 ms ... hausse ↗ et chute ↘ combinées↗ 14 ms hausse
↘ 12.4 ms chute
L'écran souffre de latences relativement élevées, insuffisant pour le jeu.
En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 240 (maximum) ms. » 52 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (25 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
37.6 ms ... hausse ↗ et chute ↘ combinées↗ 20.4 ms hausse
↘ 17.2 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. » 35 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (39.8 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) décelé 25000 Hz ≤ 40 Niveau de luminosité

Le rétroéclairage de l'écran scintille à la fréquence de 25000 Hz (certainement du fait de l'utilisation d'une MDI - Modulation de largeur d'impulsion) à un niveau de luminosité inférieur ou égal à 40 % . Aucun scintillement ne devrait être perceptible au-dessus de cette valeur.

La fréquence de rafraîchissement de 25000 Hz est élevée, la grande majorité des utilisateurs ne devrait pas percevoir de scintillements et être sujette à une fatigue oculaire accrue.

En comparaison, 51 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 9394 (minimum : 43 - maximum : 142900) Hz dans le cas où une MDI était active.

En test : le Lenovo ThinkPad L490. Modèle de test fourni par

Pour un ordinateur de bureau et de travail, Lenovo continue à ne pas faire de faux-pas avec le ThinkPad L490. La frappe avec le clavier est toujours rapide et plaisante, et l’appareil est dans l’ensemble assez puissant.

Mais le diable se cache dans les détails, et dans des éléments qui ne sont pas visibles sur le papier. Les évolutions de l’appareil – le nouvel écran et le processeur Whiskey Lake - ne vont en effet pas dans le bon sens. Le processeur subit un throttling qui le rend moins rapide que le processeur Kaby Lake du prédécesseur, et l’écran échange une luminosité légèrement supérieure contre un contraste et une valeur des noirs en baisse.

En revanche, Lenovo intègre enfin un SSD plus rapide, le Bluetooth 5.0, et propose une machine généralement moins bruyante, voire silencieuse. Nous n’apprécions cependant pas le système de refroidissement, qui fait régulièrement des pauses, même en cas de grosses sollicitations. Mais le silence plaisant, malheureusement non constant, se fait au détriment des performances et de températures très fluctuantes.

Le Lenovo ThinkPad L490 continue d’impressionner en tant que portable de bureau. Ses périphériques d’entrée, sa bonne autonomie et un SSD enfin plus rapide en font un portable de travail efficace pour les grosses firmes, les étudiants, et quiconque utilise son portable pour du traitement de texte et de la navigation web.

Il n’est pas facile de donner une vraie recommandation d’achat, puisque le L490 se démarque trop peu de son prédécesseur, tout en étant très proche du E490. Avec ce dernier, ceux qui peuvent se passer d’un emplacement ExpressCard profiteront d’un écran bien plus lumineux et contrasté, avec à peu près les mêmes performances et une autonomie aussi bonne, à un prix certainement inférieur. Pour 699 €, il vaut vraiment le coup.
