L\u2019entreprise va l\u2019\u00e9quiper en CPU et en GPU, pour un contrat de 600 millions de dollars. El Capitan vise une puissance de deux exaflops. C&#8217;est 16 fois plus rapide que le syst\u00e8me IBM\/NVIDIA Sierra qu\u2019il doit remplacer (actuellement le deuxi\u00e8me supercalculateur le plus rapide au monde) et dix fois plus rapide que Summit, le num\u00e9ro un. En outre, il sera plus performant que les 200 supercalculateurs les plus puissants\u2026 r\u00e9unis ! El Capitan devrait \u00eatre op\u00e9rationnel en 2023. Il se destine principalement aux secteurs de l&#8217;IA et de l\u2019apprentissage machine. Niveau consommation, les chiffres avanc\u00e9s se situent entre 30 MW et 40 MW, mais seraient plus proches de 30 MW.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan.jpg\"><img alt=\"Image 1 : AMD\u00a0: un supercalculateur El Capitan dix fois plus puissant que le meilleur supercalculateur actuel\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-1024x576.jpg\" alt=\"\" class=\"wp-image-558674\" srcset=\"https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-1024x576.jpg 1024w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-300x169.jpg 300w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-150x84.jpg 150w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-200x113.jpg 200w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-250x141.jpg 250w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-350x197.jpg 350w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-400x225.jpg 400w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-450x253.jpg 450w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-500x281.jpg 500w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-550x309.jpg 550w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-600x338.jpg 600w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-640x360.jpg 640w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-710x399.jpg 710w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-755x425.jpg 755w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan-1320x743.jpg 1320w, https:\/\/www.tomshardware.fr\/content\/uploads\/sites\/3\/2020\/03\/elcapitan.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure><\/div>\n\n\n\n<p>Gr\u00e2ce aux feuilles de route d\u00e9voil\u00e9es par AMD lors de la journ\u00e9e des investisseurs, on en sait d\u00e9sormais davantage sur les composants utilis\u00e9s. \u00c0 commencer par les processeurs EPYC Genoa sous architecture Zen4.
