Microsoft affirme que les PC Copilot+ sont plus rapides que le MacBook Air avec M4. L’entreprise affirme \u00e9galement que ces machines offrent une am\u00e9lioration significative des performances et de l’autonomie par rapport aux anciens ordinateurs portables Windows. Mais quand on y regarde de plus pr\u00e8s, la plupart de ces comparaisons soul\u00e8vent plus de questions qu’elles n’apportent de r\u00e9ponses. <\/p>\n\n

Microsoft n’a jamais clairement expliqu\u00e9 ce qui rend un PC Copilot+ vraiment \u00ab Plus \u00bb. Le nom \u00ab Copilot \u00bb signale d\u00e9j\u00e0 un appareil ax\u00e9 sur l’IA. La marque \u00ab Plus \u00bb, selon<\/a> l’entreprise, est le r\u00e9sultat d’un mat\u00e9riel plus puissant et de performances am\u00e9lior\u00e9es. Selon ses propres termes, ces PC prennent ce que Windows 11 fait de mieux et le \u00ab suralimentent \u00bb. <\/p>\n\n

Mais ce cadrage repose fortement sur le marketing.<\/p>\n\n

Microsoft compare souvent les PC Copilot+ \u00e0 des appareils Windows vieux de cinq ans. L’entreprise affirme que ces nouveaux syst\u00e8mes sont jusqu’\u00e0 cinq fois plus rapides. Techniquement, c’est vrai. Les processeurs, les GPU et le stockage plus r\u00e9cents surpasseront toujours le mat\u00e9riel de 2020 ou 2021. Cependant, cette am\u00e9lioration a peu \u00e0 voir avec le label Copilot+ ou les fonctionnalit\u00e9s d’IA. <\/p>\n\n

Elle refl\u00e8te simplement les progr\u00e8s mat\u00e9riels normaux.<\/p>\n\n

Les affirmations de Microsoft concernant les performances<\/h2>\n\n
\"\"<\/figure>\n\n

Dans un document marketing rep\u00e9r\u00e9<\/a> par WindowsLatest<\/em>, Microsoft a d\u00e9clar\u00e9 que les PC Copilot+ les plus performants sont plus rapides que le MacBook Air avec M4 et jusqu’\u00e0 cinq fois plus rapides qu’un PC Windows vieux de cinq ans. Le document a \u00e9t\u00e9 publi\u00e9 en d\u00e9cembre 2025, avant m\u00eame que les nouvelles puces Intel Panther Lake et Ryzen AI n’atteignent le march\u00e9. <\/p>\n\n

Microsoft \u00e9taye cette affirmation avec des benchmarks internes ex\u00e9cut\u00e9s entre juin et septembre 2025. Selon l’entreprise, les PC Copilot+ affichent des gains allant jusqu’\u00e0 5x dans les scores multic\u0153urs de Cinebench 2024 par rapport \u00e0 un syst\u00e8me \u00ab moyen \u00bb vieux de cinq ans. <\/p>\n\n

Cependant, Microsoft n’a pas publi\u00e9 les r\u00e9sultats complets.<\/p>\n\n

L’entreprise affirme \u00e9galement que ces machines sont jusqu’\u00e0 3,7 fois plus rapides dans les t\u00e2ches d’IA que les pr\u00e9c\u00e9dents PC Windows 11 AI. La raison est simple. Les anciens PC AI offraient jusqu’\u00e0 15 TOPs de performances NPU. Les PC Copilot+ font passer ce chiffre \u00e0 environ 40 TOPs. <\/p>\n\n

L’autonomie de la batterie est un autre domaine que Microsoft met en avant. L’entreprise revendique jusqu’\u00e0 19 heures de navigation web, 27 heures de lecture vid\u00e9o locale et 22 heures de streaming. Par rapport aux anciens ordinateurs portables, l’entreprise fait \u00e9tat de gains allant jusqu’\u00e0 4,4x dans certains sc\u00e9narios. <\/p>\n\n

La comparaison avec le MacBook Air<\/h2>\n\n

Microsoft affirme que les PC Copilot+ \u00ab les plus performants \u00bb battent le MacBook Air M4 dans les tests multic\u0153urs de Cinebench 2024.<\/p>\n\n

Cette affirmation manque de contexte. Microsoft ne pr\u00e9cise pas quels mod\u00e8les ont \u00e9t\u00e9 test\u00e9s, comment ils ont \u00e9t\u00e9 configur\u00e9s ni comment les benchmarks ont \u00e9t\u00e9 ex\u00e9cut\u00e9s. Sans ces d\u00e9tails, l’affirmation reste difficile \u00e0 v\u00e9rifier. <\/p>\n\n

Elle ignore \u00e9galement les facteurs du monde r\u00e9el tels que l’efficacit\u00e9, les performances soutenues et l’optimisation logicielle, des domaines dans lesquels Apple est traditionnellement performant.<\/p>\n\n

Microsoft met \u00e9galement fortement l’accent sur la touche Copilot. L’entreprise soutient que cette touche d\u00e9di\u00e9e am\u00e9liore la productivit\u00e9 des \u00e9tudiants, des employ\u00e9s de bureau et des utilisateurs occasionnels. <\/p>\n\n

Selon Microsoft, le NPU permet un multit\u00e2che plus fluide et des r\u00e9ponses plus rapides lors de l’utilisation des fonctionnalit\u00e9s de Copilot. Les \u00e9tudiants peuvent r\u00e9sumer de longs articles ou transformer des notes en flashcards. Les professionnels peuvent r\u00e9diger des e-mails pendant les r\u00e9unions. Les utilisateurs quotidiens peuvent planifier des voyages ou g\u00e9rer des t\u00e2ches en appuyant simplement sur une touche. <\/p>\n\n

Le message est clair. Microsoft estime que la touche Copilot est essentielle \u00e0 l’exp\u00e9rience PC AI. <\/p>\n\n

R\u00e9flexions finales<\/h3>\n\n

Microsoft pr\u00e9sente les PC Copilot+ comme un grand pas en avant. Mais bon nombre de ses affirmations en mati\u00e8re de performances reposent sur des comparaisons avec du mat\u00e9riel vieillissant et une transparence limit\u00e9e des benchmarks. <\/p>\n\n

Oui, ce sont des machines plus rapides et plus efficaces. Mais l’avantage \u00ab Plus \u00bb ressemble souvent plus \u00e0 une strat\u00e9gie de marque qu’\u00e0 une cat\u00e9gorie claire et mesurable. <\/p>\n\n

La comparaison avec le MacBook Air M4 attire l’attention. Ce qui manque, ce sont les d\u00e9tails n\u00e9cessaires pour rendre cette affirmation vraiment convaincante. <\/p>\n","protected":false},"excerpt":{"rendered":"
