Courte critique du convertible Lenovo ThinkPad X1 Yoga 2018 (i7-8550U, HDR WQHD)

État de l’art. Le nouveau convertible de Lenovo, classe et cher, de sa série de ThinkPad pros, voit ses composants mis à jour. Bien sûr, son point fort le plus vendeur est l’écran compatible avec la technologie HDR Dolby Vision, mais la connectivité complète et à jour est aussi à signaler. Le fabricant n’a fait (presque) aucune erreur – nous n’avons au final qu’un petit reproche à lui faire.

* ... 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
24 ms ... hausse ↗ et chute ↘ combinées↗ 6.8 ms hausse
↘ 17.2 ms chute
L'écran montre de bons temps de réponse, mais insuffisant pour du jeu compétitif.
En comparaison, tous les appareils testés affichent entre 0.8 (minimum) et 240 (maximum) ms. » 31 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont similaires à la moyenne (26 ms) de tous les appareils testés.
       Temps de réponse gris 50% à gris 80%
56.8 ms ... hausse ↗ et chute ↘ combinées↗ 21.2 ms hausse
↘ 35.6 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. » 92 % des appareils testés affichent de meilleures performances.
Cela signifie que les latences relevées sont moins bonnes que la moyenne (41.6 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, 54 % des appareils testés n'emploient pas MDI pour assombrir leur écran. Nous avons relevé une moyenne à 10727 (minimum : 43 - maximum : 588200) Hz dans le cas où une MDI était active.

Notre modèle Campuspoint du nouveau Lenovo ThinkPad X1 Yoga était disponible à 1 800 $ au moment de notre achat (2 300 € actuellement en France, sur le site de Lenovo). A 2 000 $ aux Etats-Unis, il coûte le même prix qu’un portable de jeu puissant. Si ce coût élevé n’est pas un problème pour vous, alors vous aurez un convertible élégant, polyvalent, puissant et particulièrement bien équipé, avec un très bon écran innovant, et une connectivité moderne et complète difficile à égaler aujourd’hui, à même de répondre à tous vos besoins. Des détails comme le clavier rétractable, le cache ThinkShutter pour la webcam, et les adaptateurs inclus montrent que Lenovo fait tout pour améliorer constamment sa série ThinkPad.

Si nous avions eu la version Windows 10 Pro avec la fonctionnalité de cryptage de disque BitLocker, la sécurité aurait été complète. Les utilisateurs pro apprécieront la garantie sur site de trois ans, ainsi que les excellents périphériques d’entrée, habituels aux ThinkPad. Ceux qui découvriront cette série devront dans un premier temps s’habituer aux particularités de la disposition des touches du clavier.

Le seul point faible de l’appareil est son autonomie, qui n’est pas à la hauteur. C’est le prix à payer pour avoir quatre "vrais" cœurs – même si leur gain de performances n’est pas très utile pour la bureautique, face aux anciens double cœurs avec hyper-thread tels que le i5-7200U.

Le HDR Dolby Vision et deux ports USB C Thunderbolt 3 font du convertible ThinkPad X1 Yoga 2018 de Lenovo un appareil unique.

Bien sûr nous pouvons recommander cet appareil malgré ses problèmes de haut-parleur, qui ne sont sans doutes présent que sur notre modèle de test.
