Le site HardwareLuxx<\/a> explique que les prochains processeurs pour serveur AMD Epyc Milan pourraient g\u00e9rer quatre threads par coeur physique, au lieu de deux actuellement. Ce multithreading simultan\u00e9e SMT4 serait une premi\u00e8re pour les CPU x86 AMD (apr\u00e8s les Xeon Phi d’Intel), et permettrait alors de doubler encore le nombre de coeurs virtuels au regard du syst\u00e8me d’exploitation.<\/p>\n\n\n\n

Une techno uniquement utilis\u00e9e par IBM<\/h2>\n\n\n\n

Les r\u00e9cents processeurs IBM Power utilisent d\u00e9j\u00e0 ce type de SMT (simultaneous multithreading), avec jusqu’\u00e0 8 voies de traitement par coeur physique, et dans une configuration modulable \u00e0 la vol\u00e9e en SMT4 ou SMT2. Si les nouveaux CPU Epyc Milan sur coeur Zen3, grav\u00e9s en 7nm+ EUV par TSMC, s’offrent cette techno, ils pourraient alors pr\u00e9senter jusqu’\u00e0 256 threads par puce.<\/p>\n","protected":false},"excerpt":{"rendered":"
