Zatsimikiziridwa: Apple A12Z idangogwiritsidwanso ntchito A12X kufa

Mwezi watha, Apple idavumbulutsa m'badwo watsopano wamapiritsi a iPad Pro, ndipo chodabwitsa kwa ambiri, zida zatsopanozi sizinasinthe kukhala zamphamvu kwambiri za Apple A13 SoC yaposachedwa kwambiri. M'malo mwake, iPad idagwiritsa ntchito chip chomwe Apple idachitcha A12Z. Dzinali lidawonetsa momveka bwino kuti idakhazikitsidwa pamapangidwe a Vortex / Tempest monga A12X yam'mbuyomu, yomwe idagwiritsidwa ntchito mu 2018 iPad Pro.

Kusuntha kwachilendo kwa Apple kwapangitsa ambiri kukayikira kuti A12Z mwina singakhale chipangizo chatsopano, koma ndi A12X yosatsegulidwa, ndipo tsopano anthu alandira chitsimikiziro cha chiphunzitsochi chifukwa cha TechInsights. Mu tweet yaying'ono, owunikira zaukadaulo ndi osintha uinjiniya adalemba zomwe apeza ndi zithunzi kuyerekeza ndi A12Z ndi A12X. Tchipisi ziwirizi ndizofanana: chipika chilichonse chogwira ntchito mu A12Z chili pamalo omwewo, ndipo ndichofanana ndi mu A12X.

Kusanthula kwathu kumatsimikizira #Apulosi #A12Z Chip GPU chopezeka mkati #aliPadPro (chitsanzo A2068) ndichofanana ndi A12X omwe adatsogolera. Lipoti la zomwe tapeza likuchitika ndipo lipezeka ngati gawo la TechInsights' #Logic Kulembetsa. Dziwani zambiri apa https://t.co/WWQqlPorNF pic.twitter.com/RsQEADpZsc

Ngakhale kusanthula kwa TechInsights sikuwulula zambiri ngati kukwera kwa chip, chinthu chimodzi ndi chodziwikiratu: ngakhale A12Z ili ndi makwerero atsopano poyerekeza ndi 12 A2018X, A12Z sichibweretsa chilichonse chatsopano pamawonekedwe apangidwe. Kusintha kokha pakati pa tchipisi ziwirizi ndi kasinthidwe kawo: pomwe A12X imabwera ndi magulu 7 a GPU omwe akugwira ntchito, A12Z imaphatikizapo zonse 8.

Ndipo ngakhale kuti kwenikweni kusinthaku sikumapereka phindu lalikulu, tikukamba za chinthu chatsopano chomwe chalandira magwiridwe antchito apamwamba pang'ono. A12X imapangidwa pogwiritsa ntchito njira ya TSMC ya 7nm, ndipo panthawi yomwe idatulutsidwa mu 2018, inali imodzi mwazinthu zazikulu kwambiri zomwe zidapangidwa pamachitidwe apamwamba a 7nm. Tsopano, patatha miyezi 18, kuchuluka kwa zokolola za makhiristo ogwiritsidwa ntchito kuyenera kuwonjezeka kwambiri, kotero kufunika kozimitsa midadada kuti mugwiritse ntchito makhiristo ambiri kwachepa.

Kuyerekeza kwa Apple chips

Chifukwa chiyani Apple idasankha kugwiritsanso ntchito A12X m'mapiritsi ake a 2020 m'malo motulutsa A13X ndikungoganizira za aliyense, chifukwa yankho limakhala lokhudzana ndi zachuma. Msika wamapiritsi ndi wochepa kwambiri kuposa msika wa smartphone, ndipo ngakhale Apple, yomwe ilibe mpikisano m'munda wa mapiritsi apamwamba omwe ali ndi ma processor a ARM, amagulitsa ma iPads ochepa kwambiri kuposa ma iPhones. Chifukwa chake, kuchuluka kwa zida zogawira ndalama zopangira tchipisi tapadera sikuli kokulirapo, ndipo m'badwo uliwonse wamiyezo ya lithographic, mapangidwe amakhala okwera mtengo kwambiri. Nthawi zina, sizomveka kupanga tchipisi tatsopano chaka chilichonse pazogulitsa zomwe zimakhala ndi nthawi yayitali. Zikuwoneka kuti Apple yafika pachimake ichi ndi mapurosesa ake a piritsi.
