Hnub no Huawei tau tshaj tawm nws cov flagship tshiab ib leeg-chip platform Kirin 2019 990G ntawm IFA 5. Cov yam ntxwv tseem ceeb ntawm cov khoom tshiab yog lub built-in 5G modem, raws li tau pom hauv lub npe, tab sis ntxiv rau Huawei cog lus tias muaj kev ua haujlwm siab thiab muaj peev xwm siab tshaj ntsig txog kev txawj ntse.
Kirin 990 5G ib leeg-chip platform yog tsim los siv kev txhim kho 7-nm txheej txheem thev naus laus zis siv EUV lithography (7-nm + EUV). Nyob rau tib lub sijhawm, cov khoom tshiab yog ib qho ntawm cov txheej txheem nyuaj tshaj plaws rau cov smartphones, uas muaj 10,3 billion transistors.
Ua ntej tshaj plaws, Huawei tsom mus rau qhov tseeb tias Kirin 990 5G yog lub ntiaj teb thawj ib leeg-chip smartphone platform uas muaj 5G modem built-in. Hauv 5G smartphones tam sim no, cov tuam txhab siv SoC nrog lub teeb tsa 4G modem thiab cais 5G modem. Tau kawg, xws li ib pob khoom siv ntau lub zog (txog 20%) dua li ib lub siv lead ua, thiab muaj thaj tsam loj dua 36%.
Lub modem hauv Kirin 990 5G muaj peev xwm tau txais thiab xa cov ntaub ntawv ntawm qhov nrawm ntawm 2,3 thiab 1,25 Gbps, raws li. 5G NSA thiab SA hom tau txais kev txhawb nqa. Ntxiv rau 5G tes hauj lwm, kev txhawb nqa rau tiam dhau los ntawm kev sib txuas lus ntawm tes kuj tau khaws cia.
Tus tshiab neuroprocessor module NPU yog lub luag haujlwm rau kev ua haujlwm ntawm kev txawj ntse. Nws muaj ob "loj" thiab ib "me" blocks. Thawj qhov yog tsim los ntawm Da Vinci architecture thiab tau tsim los ua cov haujlwm "hnyav". Lub "me" core, nyob rau hauv lem, muaj zog npaum. Feem ntau, Kirin 990 ua ntej ntawm nws cov neeg sib tw ntawm AI, xws li Apple A12 thiab Qualcomm Snapdragon 855, thiab tib lub sijhawm siv zog tsawg.
Kirin 990 muaj yim processors, muab faib ua peb pawg. Cov pawg "loj" suav nrog ob lub Cortex-A76 cores nrog zaus ntawm 2,86 GHz, "nruab nrab" kuj muaj ob lub Cortex-A76 cores, tab sis nrog zaus ntawm 2,36 GHz, thiab pawg "me" muaj plaub Cortex-A55 cores. nrog zaus ntawm 1,95 GHz. Qhov tseeb, piv rau Kirin 980, tus qauv tsis tau hloov pauv, tab sis cov zaus tau nce. Raws li Huawei, Kirin 990 5G processor yog ua ntej ntawm Snapdragon 855 los ntawm 10% hauv cov haujlwm ib leeg thiab 9% hauv ntau txoj haujlwm. Nyob rau tib lub sijhawm, Suav cov khoom lag luam tshiab hloov mus ua 12-35% ntau lub zog siv zog dua li Snapdragon 855.
Tab sis cov duab processor tau hloov pauv ntau yam tseem ceeb. Yog tias Kirin 980 siv 10-core Mali-G76, tom qab ntawd tus tshiab Kirin 990 twb muaj 16-core version ntawm Mali-G76. Raws li qhov tshwm sim, hais txog kev ua haujlwm ntawm cov duab, Kirin 990 yog 855% ua ntej ntawm Snapdragon 6, thiab tib lub sijhawm siv 20% tsawg zog.
Peb kuj tseem nco ntsoov tias Huawei tau nruab cov txheej txheem tshiab nrog "ntse" cache, uas muab 15% kev ua haujlwm nce ntxiv. Thiab Kirin 990 kuj tau txais ib qho tshiab dual ISP cov duab ua cov txheej txheem, uas ua haujlwm 15% sai dua thiab ua tau zoo dua, thiab tseem txo cov suab nrov hauv cov duab thiab cov yeeb yaj kiab los ntawm 30 thiab 20%, feem.
Interestingly, Huawei tseem yuav tso tawm Kirin 990 processor yam tsis muaj 5G modem built-in. Cov nti no tseem yuav muaj qhov qis dua rau cov "nruab nrab" thiab "me" pawg - 2,09 thiab 1,86 GHz, raws li, thiab nws NPU yuav muaj tsuas yog ib qho "loj" thiab ib qho "me" core.
Thawj lub xov tooj ntawm tes raws li Kirin 990 yuav yog tus flagship Huawei Mate 30, uas yuav nthuav tawm rau lub Cuaj Hlis 19 ntawm qhov kev tshwm sim tshwj xeeb hauv Munich.
