Huawei ayaa maanta si rasmi ah u daaha ka qaaday calanka cusub ee hal-chip madal Kirin 2019 990G ee IFA 5. Muuqaalka ugu muhiimsan ee badeecada cusub waa modem-ka 5G ee ku dhex jira, sida ka muuqata magaca, laakiin marka lagu daro Huawei wuxuu ballanqaadayaa waxqabad sare iyo awood sare oo la xidhiidha sirdoonka macmal.
Kirin 990 5G madal hal-chip ah ayaa la soo saaray iyadoo la adeegsanayo tignoolajiyada habsocodka 7-nm ee la hagaajiyay iyadoo la adeegsanayo EUV lithography (7-nm+ EUV). Isla mar ahaantaana, badeecadan cusubi waa mid ka mid ah processor-yada ugu adag ee taleefannada casriga ah, kaas oo leh 10,3 bilyan oo transistor ah.
Marka hore, Huawei wuxuu diiradda saarayaa xaqiiqda ah in Kirin 990 5G uu yahay aaladda casriga ah ee ugu horreysa ee hal-chip ah oo leh modem 5G ah. Taleefannada casriga ah ee 5G ee hadda jira, soosaarayaashu waxay adeegsadaan SoC oo leh modem 4G ku dhex dhisan iyo modem 5G gaar ah. Dabcan, xirmada noocan oo kale ah waxay isticmaashaa tamar ka badan (ilaa 20%) in ka badan hal crystal, waxayna leedahay 36% aag ka weyn.
Modem-ka ku jira Kirin 990 5G waxa uu awood u leeyahay in uu helo oo ku gudbiyo xogta xawaare dhan 2,3 iyo 1,25 Gbps, siday u kala horreeyaan. 5G NSA iyo qaababka SA waa la taageeray. Marka lagu daro shabakadaha 5G, taageerada jiilalkii hore ee isgaarsiinta gacanta ayaa sidoo kale la xafiday.
Qaybta cusub ee neuroprocessor NPU ayaa mas'uul ka ah hawlaha sirdoonka macmal. Waxay ka kooban tahay laba "weyn" iyo hal "yar" blocks. Kuwa ugu horreeya waxaa lagu sameeyay dhismaha Da Vinci waxaana loogu talagalay inay qabtaan hawlo "culus". Xudunta "yar", iyana, waa mid tamar aad u fiican. Guud ahaan, Kirin 990 ayaa ka horreeya tartamayaasha AI, sida Apple A12 iyo Qualcomm Snapdragon 855, isla markaana tamar yar ayuu cunaa.
Kirin 990 waxa uu leeyahay sideed koore oo processor ah, oo loo qaybiyay saddex rucubood. Kutlada "weyn" waxaa ku jira laba Cortex-A76 cores oo leh soo noqnoqoshada 2,86 GHz, "dhexdhexaad" sidoo kale waxay leedahay laba Cortex-A76, laakiin leh inta jeer ee 2,36 GHz, iyo "kutlada" yar waxay leedahay afar Cortex-A55 cores. inta jeer ee 1,95 GHz. Dhab ahaantii, marka la barbardhigo Kirin 980, qaabdhismeedku isma beddelin, laakiin soo noqnoqda ayaa kordhay. Sida laga soo xigtay Huawei, processor-ka Kirin 990 5G wuxuu ka horreeyaa Snapdragon 855 10% hawlaha hal-threaded iyo 9% hawlaha multi-threaded. Isla mar ahaantaana, badeecada cusub ee Shiinaha waxay soo baxday inay 12-35% tamar ka tayo badan tahay Snapdragon 855.
Laakiin processor-ka garaafyada ayaa ku dhacay isbeddello aad uga sii muhiimsan. Haddii Kirin 980 uu isticmaalay 10-core Mali-G76, markaa Kirin 990-ka cusub wuxuu horey u lahaa nooca 16-core ee Mali-G76. Natiijo ahaan, marka la eego waxqabadka garaafyada, Kirin 990 wuxuu 855% ka horreeyaa Snapdragon 6, isla markaana wuxuu cunaa 20% tamar ka yar.
Waxaan sidoo kale ogaanay in Huawei uu ku qalabeeyay processor-ka cusub cache "smart", kaas oo bixiya kor u kaca waxqabadka 15%. Iyo Kirin 990 waxa kale oo ay heshay processor-ka sawir-qaadaha ee Dual ISP ee cusub, kaas oo 15% si dhakhso ah oo hufan u shaqeeya, sidoo kalena hoos u dhigaya qaylada sawirrada iyo fiidyaha 30 iyo 20%, siday u kala horreeyaan.
Waxa xiiso leh in Huawei uu sidoo kale sii dayn doono processor-ka Kirin 990 oo aan lahayn modem 5G ah. Chip-kani waxa kale oo uu soo bandhigi doonaa soo noqnoqoshada hoose ee kooxaha "dhexdhexaadka ah" iyo "yar" -2,09 iyo 1,86 GHz, siday u kala horreeyaan, NPU-deeduna waxay ka koobnaan doontaa hal "weyn" iyo hal "yar" ah.
Telefoonka ugu horreeya ee ku saleysan Kirin 990 wuxuu noqon doonaa calanka Huawei Mate 30, kaasoo la soo bandhigi doono Sebtember 19-keeda munaasabad gaar ah oo ka dhici doonta Munich.
