I-ARM isandula ukuzisa ii-CPU zayo ukuba zisetyenziswe kwisizukulwana esitsha se-chipsets. Ezi CPUs ziza nokusebenza okubalulekileyo kunye nokuphucula ukusebenza kakuhle. Loluphi uhlobo lokunyuka komsebenzi oluya kubakho kwizixhobo zeflegi zika-2023? Ngaba ezi CPUs ezintsha zilindelekileyo ziya kuhlangabezana nokulindelweyo? Ukusebenza kwe-Cortex-X3, i-Cortex-A715 kunye ne-Cortex-A510 ehlaziyiweyo, eya kusetyenziswa kwi-chipset ye-flagship yesizukulwana esitsha se-Qualcomm kunye ne-MediaTek, inomdla kakhulu. Ngaphandle kokunye, makhe sijonge ngokukhawuleza kwiCortex-X3, Cortex-A715 kunye neCortex-A510 ehlaziyiweyo.
Iimpawu ze-ARM Cortex-X3
I-Cortex-X3 entsha, indlalifa ye-Cortex-X2, ingundoqo ye-3 kwi-series ye-Cortex-X eyenzelwe liqela lase-Austin Texas. Ii-cores ze-Cortex-X zihlala zijolise ekunikezeni ukusebenza okugqithisileyo kunye nobukhulu obukhulu, ukusetyenziswa kwamandla aphezulu. I-Cortex-X3 entsha ine-decoder ephuculwe ukusuka kububanzi obu-5 ukuya kububanzi obu-6. Oku kuthetha ukuba ngoku iyakwazi ukwenza imiyalelo emi-6 ngomyalelo ngamnye. I-"Branch Target Buffer" (BTB) kule ngundoqo entsha ibonakala yandiswe ngaphezu kwe-Cortex-X2 yangaphambili. Ngelixa i-L0 BTB ikhule ngamaxesha angama-10, amandla e-L1 BTB anyuke nge-50%. Isithinteli ekujoliswe kuso sesebe sibonelela ngophuculo olubonakalayo ekusebenzeni ngokulindela nokulanda imiyalelo emikhulu. Ngokufanelekileyo, i-ARM ithi i-latency yehle nge-12.2% xa kuthelekiswa ne-Cortex-X2.
Kwakhona, i-ARM ithi ubukhulu bememori ye-Macro-Op (MOP) buncitshisiwe ukusuka kwi-3K ukuya kwi-1.5K yamagalelo. Ukunciphisa umbhobho ukusuka kwi-10 ukuya kwi-9 imijikelezo kunciphisa amathuba oqikelelo olungachanekanga kwaye kuphucula kakhulu ukusebenza. Ubuninzi be-cache ye-L1-L2 amandla ahlala ehambelana ne-Cortex-X2, ngelixa ubukhulu be-ROB bunyusiwe ukusuka kwi-288 ukuya kwi-320. Ngolu phuculo, i-ARM ithi inokunikezela nge-25% yokusebenza kwencopho engcono kunezona zixhobo zangoku eziphambili zeflegi. Siza kukuxelela ngokweenkcukacha ukuba oku kuyinyani na kwizixhobo zesizukulwana esitsha eziza kwaziswa ngokuhamba kwexesha.
Iimpawu ze-ARM Cortex-A715
Umlandeli we-Cortex-A710, i-Cortex-A715 yinto ezinzileyo ejolise ekusebenzeni kwisizukulwana esilandelayo esiyilwe liqela leSophia. Kwangaxeshanye, kufuneka sikhankanye ukuba yindawo yokuqala ephakathi ukususa inkxaso ye-Aarch32. Ukungakwazi ukuqhuba izicelo ezixhaswayo ze-32-bit, i-Cortex-A715 ngoku ilungiselelwe ngokupheleleyo kwisiseko esisisiseko se-64-bit exhaswayo izicelo.
Iidekhowuda ezizenze ukuba zikwazi ukusebenzisa usetyenziso lwe-32-bit kwi-Cortex-A710 ngoku zihlaziywa kwi-Cortex-A715 kwaye zinokuqhuba kuphela usetyenziso oluxhaswayo ngamasuntswana angama-64, okukhokelela ekuncitshisweni kobungakanani beekhowudi. Xa kuthelekiswa ne-Cortex-A78, le ngundoqo entsha ine-4-width to 5-width decoder, evumela ukunyuka kwe-5% ekusebenzeni kunye nokunyuka kwe-20% ekusebenzeni kwamandla. Oku kuveza ukuba i-Cortex-A715 ngoku inokwenza ngokufanayo kwi-Cortex-X1. Singayichaza i-Cortex-A715 njenge-Cortex-A710 ephuhliswe ngakumbi.
I-ARM ehlaziyiweyo yeCortex-A510 Iinkcukacha
Ekugqibeleni, siza kwiCortex-A510 ehlaziyiweyo kwii-CPU. I-ARM iphinde yabhengeza i-Cortex-A510, eyilwe liqela laseCambridge, eyazisa kulo nyaka uphelileyo, ngotshintsho oluncinci. Ngelixa i-Cortex-A510, eyaziswa kulo nyaka uphelileyo, ayinayo inkxaso ye-Aarch32, le nkxaso inokongezwa ngokukhetha kwi-Cortex-A510 ehlaziyiweyo. Siyazi ukuba kusekho iinkqubo ezixhaswayo ze-32-bit.
Kuba inkxaso ye-Aarch32 isusiwe kwi-Cortex-A715, yinkcukacha entle ukuba le nkxaso inokongezwa ngokukhetha kwi-Cortex-A510 ehlaziyiweyo. I-Cortex-A510 ehlaziyiweyo engundoqo idla i-5% yamandla angaphantsi xa kuthelekiswa neyandulelayo. Iyakwazi ukubona lo ngundoqo we-CPU entsha njengoguqulelo lwe-Cortex-A510 oluza kusetyenziswa kwii-chipsets zeflegi ngo-2023.
I-ARM Immoralis-G715, iMali-G715 kunye neMali-G615 GPU
Ukongeza kwii-CPU ezizazisileyo, i-ARM ikwabhengeze ii-GPU zayo ezintsha. I-Immoralis-G715 GPU, enetekhnoloji yokuqala “esekwe kwi-Ray Tracing” kwicala le-ARM, iyamangalisa. Ukuxhasa ubuninzi be-16 yoqwalaselo olungundoqo, le GPU ibonelela ngeRate Rate Shading (VRS). Iphucula ukusebenza kunye nokunciphisa ukusetyenziswa kwamandla ngokunciphisa izithunzi ngokwemiboniso ethile kwimidlalo. Olu phawu luchaphazela kakuhle amava omsebenzisi.
IMediaTek yenze le ngxelo ilandelayo malunga nale GPU intsha. “Sivuyisana ne-Arm ngokusungulwa kwe-Immortalis GPU entsha, ene-hardware-based tracking ray. Idityaniswe ne-CPU entsha enamandla yeCortex-X3, sijonge phambili kwinqanaba elilandelayo lemidlalo yeselula kunye nemveliso yeFlegi yethu kunye nePremium mobile SOCs” Le ngxelo isibonisa ukuba iMediaTek SOC entsha, eza kusetyenziswa kwizixhobo zeflegi zika-2023, iya kuba ne-Immoralis-G715 GPU. Luphuhliso oluya kuchaphazela ngokufanelekileyo ikhondo lemarike ephathwayo. I-Immoralis-G715 GPU iphucula ukusebenza kunye nokusebenza kwamandla nge-15% xa kuthelekiswa nesizukulwana sangaphambili iMali-G710.
Ukongeza kwi-Immoralis-G715 GPU, iMali-G715 entsha kunye neMali-G615 GPUs nazo zabhengezwa. Ngokungafaniyo ne-Immoralis-G715, ezi GPUs "azinayo i-hardware-based Ray Tracing" inkxaso. BaneRate yokuShading kuphela (VRS). I-Mali-G715 isekela uqwalaselo oluphezulu lwe-9-core, ngelixa i-Mali-G615 isekela ukucwangciswa kwe-6-core. I-Mali-G715 entsha kunye ne-Mali-G615 inikezela ngokunyuka kwe-15% yokusebenza ngaphezu kwabangaphambili.
Ke ucinga ntoni ngezi CPUs zisanda kwaziswa kunye neeGPU? Ezi mveliso, eziza kuxhasa ii-chipsets ze-flagship ze-2023, zibaluleke kakhulu. Ungalibali ukuvakalisa iingcinga zakho kwizimvo kwaye usilandele ngeendaba ezinje.
