Ondrej Holzman Rau lub iPad Pro loj, Apple engineers tau npaj cov txheej txheem muaj zog tshaj plaws uas lawv tau tsim los rau lawv cov khoom siv mobile. Piv txwv li, A9X nti muaj ob zaug cov duab ua tau zoo ntawm iPhone 6S nrog A9 processors, ua tsaug rau cov txheej txheem tsim cov duab tsim.
Cov kws kho mob los ntawm Chipworks thiab ua ke nrog cov kws tshaj lij los ntawm AnandTech lawv tuaj rau ntau qhov kev tshawb pom nthuav.
Qhov tseem ceeb tshaj plaws yog tej zaum cov duab ntawm cov duab processor. Qhov no yog 12-core PowerVR Series7XT los ntawm Imagination Technologies, uas ib txwm tsis muab cov qauv tsim. Cov no feem ntau yog GPUs nrog 2, 4, 6, 8, lossis 16 pawg, tab sis tus qauv tsim tau yooj yim scalable, thiab Apple yog cov neeg siv khoom loj uas nws tuaj yeem thov ntau los ntawm nws cov neeg muab khoom dua li lwm tus tau txais. Raws li tsuas yog ib daim ntawv sib txawv me ntsis ntawm GPU, uas siv 128-ntsis nco tsheb npav hauv iPad Pro.
Lub iPhone 6S thiab 6S Plus rau kev sib piv siv 6-core version ntawm tib GPU, uas yog ib nrab qeeb ntawm cov duab ua haujlwm. Raws li kev tshawb pom Chipworks Txawm li cas los xij, A9X yog tsim los ntawm TSMC, zoo li nrog A9, tab sis koom nrog Samsung. Tib qhov kev faib tsis tau lees paub rau A9X, tab sis txij li Apple xav tau tsawg dua ntawm cov chips no, tej zaum tsis xav tau ntau tus neeg xa khoom.
A9X kuj txawv ntawm qhov uas nws tsis muaj buffering L3 cache, uas tau tshwm sim hauv A9, A8 thiab A7 chips txog tam sim no. Raws li AnandTech Apple tuaj yeem hloov qhov tsis muaj qhov no nrog lub L2 cache loj dua, nrawm dua LPDDR4 nco thiab dav dua 128-ntsis nco tsheb npav, thiab cov ntaub ntawv xa mus yuav txawm tias ob zaug nrawm dua li nrog A9.
lub processor ntes tau nrog lub desktop i3 zoo heev thiab tsis overclocked.
Ib yam li Apple hloov los ntawm Power processors rau Intel, nws tseem yuav hloov mus rau ARM. Ib yam li lawv khaws OSX zais cia tias nws khiav ntawm Intel, lawv yeej muaj txhua yam teeb tsa ntawm ARM ib yam nkaus. Nws tseem tsis tau mus txog lub sijhawm. Muaj ib hnub lawv yuav tshaj tawm thiab ua tau zoo. Kuv tsis lees txais qhov kev sib tham tias nws yuav muaj teeb meem nrog cov ntawv thov, thiab lwm yam, lawv tau thov tib yam thaum hloov mus rau PowerPC, tib yam rau Intel, nws txaus los muab Rozet thiab txhua yam zoo. Yog li, yog li ntawd.
