Le MacBook Air est la plus lente machine d’Apple (benchmarks)
• Article publié par Galice • Vendredi 25 janvier 2008 à 5:34
Personne ne devrait être surpris, mais si vous cherchez une vitesse impressionnante sur un ordinateur portable, nous vous conseillons d’enlever ces yeux lubriques du MacBook Air. Dans l’ensemble, ses performances sont spectaculairement anesthésiés par sa carte graphique intégrée, son processeur anémique 1.6GHz Core 2 Duo, et son disque dur de 1,8″ . Oui, vous pouvez appeler officiellement le MacBook air “la machine la plus lente de chez Apple” - mais vous le saviez déjà comme beaucoup, non? Nul n’achète un ultraportable pour sa puissance ultime.
Toutes les machines ont été testées avec Xbench 1.3 et sur Leopard (à l’exception du MBP au centre) / 1 Go de RAM.
