Comme pr\u00e9vu, Microsoft a annonc\u00e9 qu’elle avait d\u00e9velopp\u00e9 son propre processeur d’IA, mais n’a fourni que peu de d\u00e9tails. La r\u00e9v\u00e9lation a eu lieu lors de la conf\u00e9rence des d\u00e9veloppeurs Microsoft Ignite, en m\u00eame temps que celle d’un processeur serveur polyvalent bas\u00e9 sur la technologie Arm.<\/h2>\n

Les deux puces con\u00e7ues sur mesure sont : le Microsoft Azure Maia 100 AI Accelerator, optimis\u00e9 pour les t\u00e2ches d’intelligence artificielle (IA) et pour l’IA g\u00e9n\u00e9rative, et le Microsoft Azure Cobalt 100 CPU, un processeur bas\u00e9 sur Arm con\u00e7u pour ex\u00e9cuter des charges de travail de calcul \u00e0 usage g\u00e9n\u00e9ral sur le cloud Microsoft.<\/p>\n

L’entreprise n’a pas r\u00e9v\u00e9l\u00e9 beaucoup de d\u00e9tails sur les puces ni de crit\u00e8res de performance, mais elle a indiqu\u00e9 qu’elles commenceraient \u00e0 \u00eatre d\u00e9ploy\u00e9es dans les centres de donn\u00e9es de Microsoft au d\u00e9but de l’ann\u00e9e 2024.<\/p>\n

La puce d’acc\u00e9l\u00e9ration Maia 100 AI a \u00e9t\u00e9 con\u00e7ue pour ex\u00e9cuter des charges de travail d’IA sur la plateforme Azure de Microsoft et la conception a \u00e9t\u00e9 partag\u00e9e avec OpenAI, un fournisseur de mod\u00e8les d’IA g\u00e9n\u00e9rative, pour obtenir un retour d’information. Cette puce est fabriqu\u00e9e selon un processus de 5 nanom\u00e8tres et comprendrait 105 milliards de transistors.<\/p>\n

La puce, dont le nom de code \u00e9tait auparavant Athena, est en cours de d\u00e9veloppement depuis 2019 et constitue effectivement une alternative \u00e0 la H100 de Nvidia (voir Rapport : Microsoft s’appr\u00eate \u00e0 d\u00e9voiler sa propre puce d’IA<\/a>). Des rapports datant du d\u00e9but de l’ann\u00e9e 2023 laissaient entendre que Microsoft s’\u00e9tait associ\u00e9 \u00e0 Advanced Micro Devices Inc. pour d\u00e9velopper Athena et, comme AMD est le conc\u00e9dant de licence de sa technologie GPU, il pourrait s’agir d’une source de propri\u00e9t\u00e9 intellectuelle au sein d’une puce.<\/p>\n

L’unit\u00e9 centrale Cobalt 100 utilise l’architecture de jeu d’instructions Arm et se veut un processeur plus polyvalent pour les centres de donn\u00e9es, mais toujours optimis\u00e9 pour l’efficacit\u00e9 \u00e9nerg\u00e9tique.<\/p>\n

Cobalt 100 est un processeur 64 bits dot\u00e9 de 128 c\u0153urs, et Microsoft aurait d\u00e9clar\u00e9 qu’il permettait de r\u00e9duire de 40 % la consommation d’\u00e9nergie par rapport aux autres puces \u00e0 architecture Arm utilis\u00e9es par Azure.<\/p>\n

Cobalt 100 est en fait une alternative aux puces serveur Ampere Arm.<\/p>\n
