I-Exynos 990 yafika ivela kwi-Samsung. Kumsitho wetekhnoloji obanjwa kwezi ntsuku eSan José, isigebenga setekhnoloji yaseKorea iSamsung ibonise iprosesa ye-Exynos. Ezi ziiflegi zesizukulwana esilandelayo se-5G.
Isigebenga setekhnoloji yaseKorea sineminyaka embalwa kunye neeprosesa zaso, njengoko iimveliso zaso bezingafani nezinye iimveliso ezifana neApple kunye neQualcomm.
Ngaba i-Exynos 990 SoC iya kuyitshintsha le ndlela? Makhe sibone ukuba yintoni entsha kunye nentsha.
Iprosesa ye-Exynos 990 ye-Samsung ine-Octa-Core CPU enee-cores ezimbini zesiko
Yenziwe kwi-7nm EUV node
Ayiphelelanga nje ekubeni i-Samsung ishiyeke ngasemva kwi-microarchitecture, kodwa iinkqubo zokwenziwa kwenkampani azikho phambili njenge-TSMC. Inkampani yagqiba ekubeni ithathe ixesha layo kwaye ivumele ukhuphiswano lufumane umhlaba. Kodwa i-Samsung inokuzibeka ngaphezulu kwe-Apple kwakhona kulo nyaka uzayo nge-Exynos 990.
I-SoC yenziwe kusetyenziswa i-7nm EUV, eyibeka ngokuhambelana neHuawei's Kirin 990 okanye iprosesa ye-A13, enye yeeflegi ze-Apple. Kwelinye icala, ayisebenzisi iindlela eziphambili zelithography, mhlawumbi ukuzama ukuphepha imiba yokusebenza.
Nge-Exynos 990, i-Samsung ilugcinile uyilo lwe-octa-core, njengoko i-CPU yeprosesa ineempawu ezine ze-ARM Cortex A55, ii-Cortex A76 cores ezimbini, kunye nee-cores ezimbini eziyilwe yinkampani ngokwayo.
Ixesha elitsha leeprosesa eziphezulu
Iiprosesa zangaphambili ze-Samsung zangaphambili zeza neMongoose 'M' cores. Kodwa okwangoku, asiqinisekanga ukuba siza kubaleka kwimeko enye ne-Exynos 990. I-990 ilandela uyilo lweqela lemigulukudu emithathu, ngoko sithatha ukuba ii-core cores zezahlukeneyo zesantya esiphezulu se-Cortex A76 okanye i-A77. ngomphambili obanzi kunye nasemva.
Le CPU yamaqela amathathu kulindeleke ukuba inike i-Exynos 990 i-20% yokunyusa ukusebenza ngokutsho kwe-Samsung. Kodwa inkampani ayinikezi naziphi na iitshiphusi zereferensi. I-Exynos 990 ikwasinika i-ARM ye-Mali G77 GPU, esekwe kwi-architecture yase-Bhritane ye-Valhall, ephucula ukusebenza kwemizobo kunye nokusebenza kakuhle kwamandla ngenye i-20%.
Kweli nqaku, qaphela ukuba i-Apple ikwathembisa i-20% yokunyusa ukusebenza kwe-A13's CPU kunye ne-GPU.
Imodem ye-Exynos 5123 yeSamsung, imodem ye5G
Ngokungamangalisiyo, i-Exynos 990 iphinda igxile kwi-neural computations, kunye neyunithi ye-double-core neural processing unit kunye neprosesa yesignali yedijithali. Ezi zinokwenza ukuya kuthi ga kwi-10 yeebhiliyoni zemisebenzi ngomzuzwana, zibeka i-Exynos 990 phezulu kwimarike.
I-Exynos 990 ixhasa amaxabiso edatha ye-LPDDR5 ukuya kuthi ga kwi-5,500 megabits/yesibini, kwaye iindaba ezinkulu kukuba iprosesa yongeza inkxaso kwireyithi yokuhlaziya ye-120Hz. I-Samsung ayixhotyiswanga okanye Galaxy S10 hayi ukuba Qaphela 10 ngesantya sokuhlaziya se-90Hz. Kodwa ngenxa yophuhliso lwayo lwamva nje, inkampani inokuba ilungiselela ukutsiba okukhulu kunyaka ozayo.
Kunye ne-Exynos 990, i-Samsung iye yazisa i-Exynos Modem 5123 ekwaziyo ukunxibelelana ngaphezulu kwe-sub-6GHz spectrum, okt isebenzisa. Iinethiwekhi ze5G. Imodem, efana ne-Exynos 990, nayo yenziwe nge-7nm EUV. Iprosesa yomfanekiso we-Exynos 990's iyakwazi ukuxhasa ukuya kuthi ga kwi-sensors zekhamera ezintandathu, kwaye inokuphatha idatha ukusuka kwisithathu ngexesha elinye kunye nenkxaso yesisombululo esipheleleyo se-108 megapixels.
Ukusetyenziswa kwamandla
Xa ujonga indlela iitshiphusi ezisebenza ngayo, mhlawumbi eyona nto ibalulekileyo kukusebenzisa amandla azo. I-Exynos 9820 ye-Samsung yihagu yamandla amakhulu, kwaye i-SoC ayibonakali inedatha yokuthethelela iiwatts ezisebenzisayo.
Olu khululo luchasene noko u-Ice_Unvierse wayexele ngaphambili. Iindaba zamva nje zibanga ukuba i-Samsung's 'Exynos 9830' ayizukubonisa naluphi na uyilo olusisiseko, kwaye inkampani yagqiba ekubeni ithembele kuphela kwii-ARM's Cortex A77 cores.
Nangona kunjalo, kubonakala ngathi ulwazi lwalunethuba le-80% lokuchaneka. Ke, kukhangeleka ngathi i-Samsung yonwabile ngee-cores zayo kwaye ikhethe ukuzicokisa nge-Exynos 990.
Ewe kunjalo, i-Exynos 990 isenokungabi yeyokuphela kwe-SoC ephezulu ye-Samsung, kodwa amathuba okuba oku kwenzeke mancinci. Emva kwayo yonke loo nto, inkampani ayikwazi ukuthengisa iiprosesa zayo kwezinye iinkampani ngenxa yesivumelwano seCDMA kunye neQualcomm eqala ngo-1993.
Lilonke, umdyarho wentengiso ye-SoC uthathe inguqu enkulu kulo nyaka emva kokuba i-Apple's A13 isemthethweni. Into ephambili ye-chip kulawulo lwayo lwe-voltage, eya kudlala indima ebalulekileyo ekulawuleni ukusetyenziswa kwamandla, njengoko i-SoC idonsa amandla amaninzi kunangaphambili. Kodwa, ngokungafaniyo ne-Exynos 9820, oku kunyuka kokusetyenziswa kubonisa ukunyuka komsebenzi.
Njengeyesibini kwaye yamva nje iprosesa ye-EUV ye-Samsung, i-Exynos 990 ithwele uxanduva olunzima. I-chip ye-5123 kunye nemodem iya kuqalisa imveliso yobuninzi kamva kulo nyaka, kufuneka ilungele ukwahluka kwamazwe ngamazwe komgca. Samsung Galaxy S11 kunye neNqaku 11. Ekugqibeleni, ukuba izinto zihamba kakuhle kunye ne-chip, i-Samsung-Semiconductors inokutsala abathengi abatsha.
Kwicandelo lamagqabantshintshi ezantsi kwephepha, unokushiya uluvo lwakho malunga ne-chip entsha elindeleke kwisiphelo esiphezulu seefowuni ze-Samsung Galaxy.
