Avec sa famille de processeurs de 9e g\u00e9n\u00e9ration, Intel utilise un joint en soudure pour optimiser l\u2019\u00e9change thermique entre le die du processeur et sa capsule (STIM, pour solder-based thermal interface material<\/em>). Cela permet un meilleur transfert de chaleur qu\u2019avec les p\u00e2tes thermiques fluides. Depuis le lancement de la s\u00e9rie, on sait que le processus STIM se limite aux processeurs K, tels que i9-9900K<\/a> et i7-9700K<\/a>. Les mod\u00e8les non K conservent la bonne vielle p\u00e2te thermique. Sur Twitter, momomo_us<\/a> a d\u00e9mont\u00e9 un Intel Core i5-9400F pour le confirmer. Il a \u00e9galement fait une autre d\u00e9couverte\u2026<\/p>\n\n\n\n

Processeurs s\u00e9rie F en U0<\/h3>\n\n\n\n

Momomo_us<\/a> a d\u00e9capsul\u00e9 un i5-9400F et l’a compar\u00e9 \u00e0 un i5-9600K. On voit bien les r\u00e9sidus sur le premier, et les fragments de soudure sur l\u2019autre. On remarque aussi que le die du i5-9600K est bien plus gros que celui du i5-9400F, bien que les deux processeurs soient des 6 c\u0153urs avec un cache L3 de 9 Mo. L’absence d\u2019iGPU<\/a> n\u2019est pas en cause, puisqu\u2019il est physiquement bien pr\u00e9sent sur le i5-9400F, simplement d\u00e9sactiv\u00e9. Cela s\u2019explique en fait parce que le i5-9400F est une r\u00e9vision U0, semblable aux processeurs “Coffee Lake” 6 c\u0153urs de 8e g\u00e9n\u00e9ration. En revanche, le i5-9600K est, comme d\u2019autres processeurs de 9e g\u00e9n\u00e9ration, en P0. Il a par cons\u00e9quent un die \u00e0 huit c\u0153urs, dont deux sont d\u00e9sactiv\u00e9s. <\/p>\n\n\n\n

La question est maintenant de savoir si Intel conservera une p\u00e2te thermique m\u00e9tal pour les processeurs d\u00e9bloqu\u00e9s de la s\u00e9rie F, comme le Core i9-9900KF.<\/p>\n\n\n\n
