Kev tsim kho cov qauv zoo siv tau kho qhov muag muaj zog, kev ntseeg hluav taws xob, thiab ntev} lub sij hawm kev ntseeg tau nrog lub hom phiaj tsis ua haujlwm hauv qab no 500 haum
Hypirale Datorge Dative ua ntej lub zog ua ntej (30-37.5 Gbps / Watt) dhau ntawm cov nqi electront, nrog ai gpu plev tshem tawm cov kev nthuav dav hauv lub zog
