Le site Phoronix<\/a> a rep\u00e9r\u00e9 une ligne de code, dans la derni\u00e8re version des pilotes AMDGPU pour Linux, qui confirmerait la rumeur qui disait que Vega 20 supporterait le xGMI. Un peu \u00e0 la mani\u00e8re du NVLink<\/a> de NVIDIA, le xGMI serait une nouvelle interface permettant d\u2019interconnecter plusieurs GPU. Bas\u00e9e sur l\u2019Infinity Fabric<\/a>, cette technologie pourrait permettre de cr\u00e9er un pont entre deux Vega 20, via une connexion peer to peer \u00e0 grande vitesse, sans saturer le bus PCI-Express.<\/p>\n

Pas forc\u00e9ment destin\u00e9 au gaming<\/h3>\n

\"Image<\/span><\/span>Notez cependant, comme le fait remarquer TechpowerUp<\/a>, que le xGMI et le NVLink ne signifient pas forc\u00e9ment le retour de l\u2019optimisation multi-GPU dans le secteur du jeu vid\u00e9o. Ces connecteurs ont s\u00fbrement \u00e9t\u00e9 impl\u00e9ment\u00e9s sur les nouvelles cartes graphiques, afin d\u2019unifier les technologies d\u2019interconnexion des GPU sous une seule interface. Ils sont probablement, pour l\u2019instant, destin\u00e9s \u00e0 l\u2019apprentissage profond. D\u2019ailleurs, AMD n\u2019a toujours pas confirm\u00e9 si Vega 20 sera \u00e9galement d\u00e9clin\u00e9e en version grand public, pour le gaming (ce qui est peu probable pour l’instant).<\/p>\n","protected":false},"excerpt":{"rendered":"
