Yakasimbiswa: Apple A12Z ingori kushandiswazve A12X kufa

Mwedzi wapera, Apple yakafumura chizvarwa chitsva chemapiritsi ePad Pro, uye kushamisika kwevakawanda, zvishandiso zvitsva hazvina kukwidziridza kune imwe simba rakasiyana reApple yazvino A13 SoC. Pane kudaro, iyo iPad yakashandisa chip iyo Apple yakadana A12Z. Iri zita rairatidza zvakajeka kuti raive rakavakirwa pane imwecheteyo Vortex / Tempest architecture seyaimbova A12X, iyo yakashandiswa mu2018 iPad Pro.

Kufamba kweApple kusingajairiki kwaita kuti vazhinji vafungidzire kuti A12Z inogona kunge isiri chip nyowani, asi ingave isina kuvhurwa A12X, uye iko zvino veruzhinji vawana simbiso yedzidziso iyi nekuda kweTechInsights. Mune pfupi tweet, iyo tekinoroji yekuongorora uye reverse engineering femu yakatumira zvayawana uye mifananidzo ichienzanisa iyo A12Z neA12X. Iwo maviri machipi akafanana zvachose: yega yega inoshanda muA12Z iri munzvimbo imwechete, uye yakakura saizi semuA12X.

Ongororo yedu inosimbisa #Apple #A12Z GPU chip inowanikwa mukati #iPadPro (modhi A2068) yakafanana neyakatangira A12X. Chirevo chezvatakawana chiri kuenderera mberi uye chichave chiripo sechikamu cheTechInsights' #Logic Kunyoresa. Dzidza zvakawanda pano https://t.co/WWQqlPorNF pic.twitter.com/RsQEADpZsc

Nepo ongororo yeTechInsights isingaburitse zvimwe senge chip stepping, chinhu chimwe chakajeka: kunyangwe iyo A12Z iine nhanho nyowani ichienzaniswa ne12 A2018X, iyo A12Z haina kuunza chero chinhu chitsva maererano nedhizaini. Shanduko chete inooneka pakati pemachipisi maviri ndiko kumisikidzwa kwavo: nepo A12X ichiuya ne7 inoshanda maGPU masumbu, iyo A12Z inosanganisira ese masere.

Uye kunyange zvazvo chaizvoizvo shanduko iyi isingapi pfuma yakawanda, isu tichiri kutaura nezvechigadzirwa chitsva chakagamuchira kuita kwepamusoro zvishoma. Iyo A12X inogadzirwa ichishandisa TSMC's 7nm process, uye panguva yekuburitswa kwayo muna 2018, yaive imwe yemachipi makuru akagadzirwa pane yepamusoro 7nm maitiro. Iye zvino, mwedzi ye18 gare gare, chiyero chegoho remakristasi anoshandisika chinofanira kunge chakawedzera zvakanyanya, saka kukosha kwekudzima mabhuroko ekushandisa mamwe makristasi kwadzikira.

Nei Apple yakasarudza kushandisa zvakare iyo A12X mumahwendefa ayo e2020 pane kuburitsa iyo A13X fungidziro yemunhu wese, sezvo mhinduro ingangouya kuhupfumi. Musika wepiritsi wakanyanya kudiki pane musika we smartphone, uye kunyange Apple, iyo inenge isina kukwikwidza mumunda wemapiritsi ekupedzisira ane maARM processors, inotengesa kure zvishoma iPads kupfuura iPhones. Nekudaro, huwandu hwemidziyo yekugovera mitengo yekugadzira machipisi akasarudzika haina kukura zvakanyanya, uye nechizvarwa chimwe nechimwe che lithographic zviyero, dhizaini inowedzera uye inodhura. Pane imwe nguva, hazvina musoro kugadzira machipisi matsva gore rega rega kune zvigadzirwa zvine mapfupi anomhanya. Sezviri pachena Apple yasvika pachiitiko ichi nema processor ayo epiritsi.
