ʻO ka hōʻoia topology i ke ao no ka 7nm GPU nui loa o AMD i lawe wale i 10 mau hola

ʻO ka hakakā no ka mea kūʻai aku ke koi nei i nā mea hana semiconductor contract e neʻe kokoke aku i nā mea hoʻolālā. ʻO kahi koho e ʻae i nā mea kūʻai mai ka honua holoʻokoʻa e pōmaikaʻi mai nā mea hana EDA i hōʻoia ʻia me nā hoʻololi hou a pau, ʻo ia ke kau ʻana i nā lawelawe ma nā ao ākea. I kēia mau lā, ua hōʻike ʻia ka kūleʻa o kēia ala e kahi lawelawe no ka nānā ʻana i ka topology o ka hoʻolālā chip, i kau ʻia ma ka platform Microsoft Azure e TSMC. Hoʻokumu ʻia ka hopena i ka polokalamu Mentor Graphics 'Caliber nmDRC mua, hoʻopili ʻia i ʻApelila 2017 e ka German Siemens.

Pehea hooiaioia ma AMD, nānā piha i ka topology (kino). ka paʻakikī loa Ma ka moʻolelo o ka hui, ua hoʻopau ka 7nm Vega 20 GPU me 13,2 billion transistors i ka hoʻolālā i nā hola 10 wale nō. Ua emi iho ka lua o ka hala. He hopena maikaʻi loa nā hala ʻelua i 19 mau hola o ka hoʻāʻo ʻana i ke ao, hilinaʻi ʻo AMD. Hōʻike kēia i ka kūleʻa o kēia ala a wehe i nā manawa hou no nā mea hoʻolālā: hiki i nā huahana hou ke ʻike koke ʻia ma ka mākeke a me ka hoʻokō ʻoi aku ka maikaʻi.

He mea hoihoi ia e hoʻomaopopo i ka AMD Vega 20 GPU i hoʻāʻo ʻia ma kahi kahua mamao ma AMD EPYC 7000 series processors. Ua kau ʻia ka polokalamu Caliber nmDRC ma 4410 cores a i ʻole 69 mau mīkini virtual papa HB (me ka bandwidth hoʻomanaʻo kiʻekiʻe loa). No ka hana hoʻomanaʻo nui e like me ka nānā ʻana i ka topology processor, he mea nui loa kēia.

Ua kōkua pū nā mea hoʻomohala polokalamu Caliber nmDRC i ka kūleʻa o ka ʻoihana. Pono ka polokalamu hou i ka 50% emi ka hoʻomanaʻo e hana i nā hana hōʻoia topology like. ʻO ka AMD's EPYC platform, wahi a ka hui, hāʻawi iā 33% ʻoi aku ka bandwidth ma mua o nā makana a Intel. ʻO ka mea kūikawā, ma ka lawelawe Azure, e holo ana ka subsystem hoʻomanaʻo i ka wikiwiki a hiki i ka 263 GB / s, a hāʻawi nā mīkini virtual HB-class i ka 80% ʻoi aku ka nui o ka throughput ma mua o nā paepae ao hoʻokūkū.
