Ua wehe ʻo Huawei i kēia lā i kāna kahua hoʻokūkū hoʻokahi-chip hou Kirin 2019 990G ma IFA 5. ʻO ka hiʻohiʻona koʻikoʻi o ka huahana hou ka modem 5G i kūkulu ʻia, e like me ka mea i hōʻike ʻia ma ka inoa, akā hoʻohui ʻo Huawei e hoʻohiki i nā hana kiʻekiʻe a me nā mana holomua e pili ana i ka naʻauao artificial.
Hana ʻia ka Kirin 990 5G hoʻokahi-chip platform me ka hoʻohana ʻana i kahi ʻenehana kaʻina hana 7-nm i hoʻomaikaʻi ʻia me ka hoʻohana ʻana i ka lithography EUV (7-nm+ EUV). I ka manawa like, ʻo ka huahana hou kekahi o nā kaʻina hana paʻakikī no nā smartphones, nona ka 10,3 billion transistors.
ʻO ka mea mua, ke nānā aku nei ʻo Huawei i ka ʻoiaʻiʻo ʻo ka Kirin 990 5G ka honua mua o ka honua holoʻokoʻa i loaʻa kahi modem 5G i kūkulu ʻia. Ma nā kelepona 5G o kēia manawa, hoʻohana nā mea hana i kahi SoC me kahi modem 4G i kūkulu ʻia a me kahi modem 5G ʻokoʻa. ʻOiaʻiʻo, ʻoi aku ka nui o ka ikehu (a hiki i 20%) ma mua o hoʻokahi aniani, a he 36% ka nui.
Hiki i ka modem ma Kirin 990 5G ke loaʻa a me ka hoʻouna ʻana i ka ʻikepili i ka wikiwiki o 2,3 a me 1,25 Gbps, kēlā me kēia. Kākoʻo ʻia nā ʻano 5G NSA a me SA. Ma waho aʻe o nā pūnaewele 5G, ua mālama pū ʻia ke kākoʻo no nā hanauna o mua o nā kamaʻilio kelepona.
ʻO ka NPU neuroprocessor module hou ke kuleana no nā hana o ka naʻauao. Aia i loko o ʻelua mau poloka "nui" a hoʻokahi "liʻiliʻi". Hana ʻia nā mea mua ma Da Vinci architecture a ua hoʻolālā ʻia e hana i nā hana "kaumaha". ʻO ke kumu "liʻiliʻi", ʻoi aku ka ikaika o ka ikehu. Ma keʻano laulā, aia ka Kirin 990 ma mua o kāna mau mea hoʻokūkū ma ke ʻano o AI, e like me Apple A12 a me Qualcomm Snapdragon 855, a ma ka manawa like e hoʻopau i ka ikehu.
Loaʻa iā Kirin 990 ʻewalu mau kaʻina hana, i māhele ʻia i ʻekolu mau pūʻulu. Loaʻa i ka hui "nui" ʻelua ʻāpana Cortex-A76 me ke alapine o 2,86 GHz, ʻo ka "medium" pū kekahi ʻelua Cortex-A76 cores, akā me ka alapine o 2,36 GHz, a ʻo ka "liʻiliʻi" ʻehā ʻehā Cortex-A55 cores. me ka alapine o 1,95 .980 GHz. ʻOiaʻiʻo, i hoʻohālikelike ʻia i ka Kirin 990, ʻaʻole i loli ke ʻano, akā ua hoʻonui ʻia nā alapine. Wahi a Huawei, ʻo ka ʻōnaehana Kirin 5 855G ma mua o ka Snapdragon 10 e 9% i nā hana hoʻokahi-threaded a me 12% i nā hana multi-threaded. I ka manawa like, ua lilo ka huahana hou o Kina i 35-855% ʻoi aku ka ikaika ma mua o ka Snapdragon XNUMX.
Akā ʻoi aku ka nui o nā loli koʻikoʻi o ka mea hana kiʻi. Inā hoʻohana ka Kirin 980 i kahi 10-core Mali-G76, a laila ua loaʻa i ka Kirin 990 hou kahi mana 16-core o ka Mali-G76. ʻO ka hopena, ma ke ʻano o ka hana kiʻi kiʻi, ʻo ka Kirin 990 ka 855% ma mua o ka Snapdragon 6, a ma ka manawa like e hoʻopau ai i ka 20% ka liʻiliʻi o ka ikehu.
Hoʻomaopopo pū mākou ua hoʻolako ʻo Huawei i ka kaʻina hana hou me kahi cache "akamai", e hāʻawi ana i ka hoʻonui hana o 15%. A ua loaʻa hoʻi i ka Kirin 990 kahi kaʻina hana kiʻi kiʻi Dual ISP hou, e hana ana i ka 15% wikiwiki a ʻoi aku ka maikaʻi, a hoʻemi hoʻi i ka walaʻau i nā kiʻi a me nā wikiō e 30 a me 20%, kēlā me kēia.
ʻO ka mea mahalo, e hoʻokuʻu pū ʻo Huawei i ka ʻōnaehana Kirin 990 me ka ʻole o kahi modem 5G i kūkulu ʻia. E hōʻike pū ana kēia chip i nā alapine haʻahaʻa no nā hui "medium" a me "liʻiliʻi" - 2,09 a me 1,86 GHz, kēlā me kēia, a ʻo kāna NPU he hoʻokahi wale nō "nui" a hoʻokahi "liʻiliʻi".
ʻO ka polokalamu kelepona mua i hoʻokumu ʻia ma Kirin 990 ka poʻokela Huawei Mate 30, e hōʻike ʻia ma Kepakemapa 19 ma kahi hanana kūikawā ma Munich.
