Lub hli tas los, Apple tau nthuav tawm lub cim tshiab ntawm iPad Pro cov ntsiav tshuaj, thiab ua rau muaj kev xav tsis thoob ntawm ntau, cov khoom siv tshiab tsis tau hloov mus rau qhov muaj zog dua ntawm Apple qhov tseeb A13 SoC. Hloov chaw, iPad siv lub nti uas Apple hu ua A12Z. Lub npe no tau qhia meej tias nws tau ua raws li tib lub Vortex / Tempest architecture raws li yav dhau los A12X, uas tau siv hauv 2018 iPad Pro.
Apple qhov kev hloov pauv txawv txawv tau ua rau ntau tus xav tias A12Z tej zaum yuav tsis yog lub nti tshiab, tab sis yog qhov qhib A12X, thiab tam sim no cov pej xeem tau txais kev pom zoo ntawm qhov kev xav no ua tsaug rau TechInsights. Nyob rau hauv luv luv tweet, cov kev tsom xam thiab thim rov qab engineering tuam txhab tso tawm nws cov kev tshawb pom thiab cov duab piv rau A12Z thiab A12X. Ob lub chips yog qhov zoo ib yam: txhua qhov kev ua haujlwm thaiv hauv A12Z yog nyob rau tib qhov chaw, thiab nws yog qhov loj tib yam li hauv A12X.
Peb qhov kev txheeb xyuas pom tseeb GPU nti pom hauv (qauv A2068) yog tib yam li A12X ua ntej. Ib tsab ntawv ceeb toom ntawm peb qhov kev tshawb pom tab tom pib & yuav muaj ua ib feem ntawm TechInsights ' Subscription. Kawm ntxiv ntawm no

Thaum TechInsights tsom xam tsis qhia cov ntsiab lus ntxiv xws li chip stepping, ib yam yog qhov tseeb: txawm tias A12Z muaj kev nce qib tshiab dua piv rau 12 A2018X, A12Z tsis coj dab tsi tshiab ntawm kev tsim. Qhov tsuas pom kev hloov pauv ntawm ob lub chips yog lawv qhov teeb tsa: thaum A12X los nrog 7 pawg GPU nquag, A12Z suav nrog tag nrho 8.
Thiab txawm hais tias qhov tseeb qhov kev hloov pauv no tsis tau txais txiaj ntsig ntau dhau, peb tseem tab tom tham txog cov khoom tshiab uas tau txais . A12X yog tsim los siv TSMC's 7nm txheej txheem, thiab thaum lub sijhawm nws tso tawm xyoo 2018, nws yog ib qho ntawm cov chips loj tshaj plaws uas tsim los ntawm cov txheej txheem 7nm siab heev. Tam sim no, 18 lub hlis tom qab, cov txiaj ntsig ntawm cov khoom siv lead ua siv tau yuav tsum tau nce ntau, yog li qhov yuav tsum tau tua cov blocks kom siv ntau cov muaju tau txo qis.

Vim li cas Apple thiaj xaiv rov siv A12X hauv nws cov ntsiav tshuaj 2020 es tsis txhob tso A13X yog leej twg xav tau, raws li cov lus teb yuav los rau kev lag luam. Cov ntsiav tshuaj kev lag luam yog me me dua li lub lag luam smartphone, thiab txawm tias Apple, uas yuav luag tsis muaj kev sib tw hauv kev lag luam ntawm cov ntsiav tshuaj high-end nrog ARM processors, muag iPads tsawg dua iPhones. Yog li, tus naj npawb ntawm cov khoom siv los faib cov nqi ntawm kev tsim cov chips tshwj xeeb tsis yog loj heev, thiab nrog rau txhua tiam ntawm cov qauv lithographic, kev tsim ua ntau dua thiab kim dua. Qee lub sij hawm, nws tsis muaj kev nkag siab los tsim cov chips tshiab txhua xyoo rau cov khoom lag luam nrog luv luv. Pom tau tias Apple tau mus txog qhov tseem ceeb no nrog nws cov ntsiav tshuaj processors.
