I-ARM isanda kwethula ama-CPU ayo ukuthi asetshenziswe kuma-chipsets esizukulwane esisha. Lawa ma-CPU eza nokusebenza okubalulekile nokusebenza kahle kwentuthuko. Hlobo luni lokukhula kokusebenza oluzoba khona kumadivayisi aphambili ango-2023? Ingabe lawa ma-CPU amasha alindelwe azohlangabezana nokulindelwe? Ukusebenza kwe-Cortex-X3, i-Cortex-A715 kanye ne-Cortex-A510 evuselelwe, ezosetshenziswa kuma-chipset esizukulwane esisha se-flagship ye-Qualcomm ne-MediaTek, kuyathakazelisa kakhulu. Ngaphandle kokuchitha isikhathi, ake sibheke ngokushesha i-Cortex-X3, Cortex-A715 kanye ne-Cortex-A510 evuselelwe.
Imininingwane ye-ARM Cortex-X3
I-Cortex-X3 entsha, elandela i-Cortex-X2, iwumgogodla wesi-3 ochungechungeni lwe-Cortex-X eklanywe iqembu lase-Austin Texas. Ama-Cortex-X series cores ahlala ehlose ukunikeza ukusebenza okwedlulele ngosayizi omkhulu, ukusetshenziswa kwamandla okuphezulu. I-Cortex-X3 entsha ine-decoder eye yathuthukiswa isuka kububanzi obungu-5 yaya kububanzi obungu-6. Lokhu kusho ukuthi isingakwazi ukucubungula imiyalo engu-6 ngomyalelo ngamunye. I-“Branch Target Buffer” (BTB) kulo mongo omusha ibonakala ikhuliswe kakhulu kune-Cortex-X2 yangaphambilini. Ngenkathi i-L0 BTB ikhule izikhathi ezingu-10, umthamo we-L1 BTB ukhuphuke ngo-50%. Ibhafa eqondiwe yegatsha ihlinzeka ngokuthuthuka okuphawulekayo ekusebenzeni ngokulindela nokulanda imiyalelo emikhulu. Ngokunjalo, i-ARM ithi ukubambezeleka kwehle ngo-12.2% uma kuqhathaniswa neCortex-X2.
Futhi, i-ARM ithi usayizi wenkumbulo ye-Macro-Op (MOP) wehlisiwe ukusuka ku-3K ukuya kokufakiwe okungu-1.5K. Ukunciphisa ipayipi ukusuka kumijikelezo eyi-10 kuye kweyi-9 kunciphisa amathuba okuqagela okungalungile futhi kuthuthukisa kakhulu ukusebenza. Amandla enqolobane e-L1-L2 aphezulu ahlala elingana ne-Cortex-X2, kuyilapho usayizi we-ROB ukhushuliwe kusukela ku-288 kuya ku-320. Ngalokhu kuthuthukiswa, i-ARM ithi ingaletha ukusebenza okuphezulu okuphezulu okungu-25% kunamadivayisi ahamba phambili amanje. Sizokutshela ngokuningiliziwe ukuthi lokhu kuyiqiniso yini kumadivayisi esizukulwane esisha azokwethulwa ngokuhamba kwesikhathi.
Imininingwane ye-ARM Cortex-A715
Umlandeli we-Cortex-A710, i-Cortex-A715 iwumongo wesizukulwane esilandelayo ogxile ekusebenzeni oklanywe ithimba le-Sophia. Ngasikhathi sinye, sidinga ukusho ukuthi kungowokuqala okuphakathi nendawo ukususa ukwesekwa kwe-Aarch32. Njengoba ayikwazi ukusebenzisa izinhlelo zokusebenza ezisekelwayo ezingama-32-bit, i-Cortex-A715 manje isilungiselelwe ngokugcwele ngesisekelo esiyisisekelo sezinhlelo zokusebenza ezisekelwayo ezingama-64-bit.
Amadekhoda awazivumela ukuthi asebenzise izinhlelo zokusebenza ezingama-32-bit ku-Cortex-A710 manje asevuselelwe ku-Cortex-A715 futhi angasebenzisa kuphela izinhlelo zokusebenza ezisekelwa ngamabhithi angama-64, okuholela ekuncipheni kosayizi wamadekhoda. Uma kuqhathaniswa ne-Cortex-A78, lo mgogodla omusha une-decoder engu-4-width kuya ku-5-width, okuvumela ukukhuphuka kokusebenza ngo-5% kanye nokwenyuka kwamandla ka-20%. Lokhu kuveza ukuthi iCortex-A715 manje isingenza ngendlela efanayo neCortex-X1. Singachaza i-Cortex-A715 njenge-Cortex-A710 ethuthukisiwe.
Imininingwane ye-ARM Cortex-A510 elungisiwe
Ekugcineni, siza ku-Cortex-A510 evuselelwe kuma-CPU. I-ARM isiphinde yamemezela i-Cortex-A510, eklanywe yiqembu laseCambridge, eyethule ngonyaka odlule, ngezinguquko ezincane. Nakuba i-Cortex-A510, eyethulwa ngonyaka odlule, ingenakho ukusekelwa kwe-Aarch32, lokhu kusekelwa kungangezwa ngokuzikhethela ku-Cortex-A510 evuselelwe. Siyazi ukuthi kusenezinhlelo ezisekelwayo ezingama-32-bit.
Njengoba ukwesekwa kwe-Aarch32 kususiwe ku-Cortex-A715, kuyimininingwane enhle ukuthi lokhu kusekelwa kungangezwa ngokuzikhethela ku-Cortex-A510 evuselelwe. I-Cortex-A510 core ebuyekeziwe idla amandla amancane angu-5% uma iqhathaniswa neyandulelayo. Ingabona lo mgogodla omusha we-CPU njengenguqulo eyenziwe kahle kakhulu ye-Cortex-A510 ezosetshenziswa kuma-chipset e-flagship ngo-2023.
I-ARM Immoralis-G715, iMali-G715 ne-Mali-G615 GPU
Ngaphezu kwama-CPU eyethulile, i-ARM iphinde yamemezela ama-GPU ayo amasha. I-Immoralis-G715 GPU, enobuchwepheshe bokuqala “okusekelwe ku-Ray Tracing” ohlangothini lwe-ARM, iyamangalisa kakhulu. Isekela ukulungiselelwa okuyisisekelo okungu-16, le GPU inikeza i-Variable Rate Shading (VRS). Ithuthukisa ukusebenza futhi inciphise ukusetshenziswa kwamandla ngokunciphisa izithunzi ngokuya ngezigcawu ezithile kumageyimu. Lesi sici sithinta kahle ulwazi lomsebenzisi.
IMediaTek yenze isitatimende esilandelayo mayelana nale GPU entsha. “Sihalalisela i-Arm ngokwethulwa kwe-Immortalis GPU entsha, equkethe ukulandelela kwe-ray okusekelwe ku-hardware. Sihlanganiswe ne-Cortex-X3 CPU entsha enamandla, sibheke ngabomvu izinga elilandelayo lemidlalo yeselula kanye nokukhiqiza kuma-SOC ethu eselula e-Flagship & Premium” Lesi sitatimende sisibonisa ukuthi i-MediaTek SOC entsha, ezosetshenziswa kumadivayisi aphambili ango-2023, izoba ne-Immoralis-G715 GPU. Kuyintuthuko ezoba nomthelela omuhle ekuhambeni kwemakethe ephathwayo. I-Immoralis-G715 GPU ithuthukisa ukusebenza nokusebenza kahle kwamandla ngo-15% uma kuqhathaniswa nesizukulwane sangaphambilini i-Mali-G710.
Ngaphezu kwe-Immoralis-G715 GPU, iMali-G715 entsha kanye neMali-G615 GPUs nazo zimenyezelwe. Ngokungafani ne-Immoralis-G715, lawa ma-GPU "awanakho ukusekelwa kwe-Ray Tracing" okusekelwe ku-hardware. Bane-Vaable Rate Shading (VRS) kuphela. I-Mali-G715 isekela ukucushwa kwe-9-core esiphezulu, kuyilapho i-Mali-G615 isekela ukucushwa kwe-6-core. I-Mali-G715 entsha kanye ne-Mali-G615 zinikeza ukukhuphuka kokusebenza okungu-15% kunezandulelayo.
Manje-ke ucabangani ngalawa ma-CPU nama-GPU asanda kwethulwa? Le mikhiqizo, ezosekela ama-chipsets e-flagship ka-2023, ibaluleke kakhulu. Ungakhohlwa ukuveza imicabango yakho kumazwana futhi usilandele ukuze uthole izindaba ezinjalo.
