Musangano weSemicon West 2019, wakaitwa pasi pezvishandiso zveApplied Materials, wakatobereka michero muchimiro chemashoko anonakidza kubva ku AMD CEO Lisa Su. Kunyangwe AMD pachayo isina kugadzira ma processor ari ega kwenguva yakareba, gore rino yakapfuura mukwikwidzi wayo mukuru maererano nehuwandu hwekufambira mberi kwetekinoroji inoshandiswa. Kunyangwe GlobalFoundries yakasiya AMD yega neTSMC munhangemutange ye7nm tekinoroji zviyero, budiriro mukubata iyi nhanho yelithographic process inowanzonzi ndeye AMD. Mukupedzisira, kambani inoenderera mberi nekugadzira ma processors ayo akazvimirira, uye TSMC yakangopihwa kuti igadzirise mapurojekiti aya kune ayo ekugadzira.
Sezvo munhu anogona kutonga kubva pazvidimbu zvemifananidzo zvakaburitswa mukati Indasitiri blogger David Schor, pamusangano weSemicon West, Lisa Su akabata nyaya dzazvino dzakatarisana neindasitiri yesemiconductor. Mukunzwisisa kwe AMD, kuchiri kumberi kunyora iyo inonzi "Mutemo waMoore" sedzidziso isina kururama, sezvo yaive kufambira mberi mumunda we lithographic iyo yakabvumira kambani kupeta kaviri kumhanya kwema processor mumakore maviri nehafu apfuura. zvichienzaniswa nezvigadzirwa zvemakore gumi apfuura.
Chero zvazvingava, maitiro ehunyanzvi mune ino mamiriro akaverengera angangoita makumi mana muzana emupiro mukuwedzera kwekuita, semanotsi e AMD pane siraidhi. Kana tikawedzera kune iyi imwe 40%, yakapihwa nekugadzirisa padanho resilicon, tinowana iyo yakazara makumi matanhatu%. Shanduko paiyo microarchitecture level yakaverengera 20% yekuwedzera kwese, manejimendi emagetsi akaverengera 60%, uye compilers vakaverengera imwe 17%. Chero zvingataura, pasina kufambira mberi mumunda we lithography, AMD ingadai isina kukwanisa kubudirira zvakadaro.
AMD manejimendi inocherekedzawo imwe maitiro: iyo yakaonda iyo tekinoroji maitiro, iyo inodhura yakakura makristasi ichave kugadzira. Semuenzaniso, kristaro yakajairika ine core area ye250 mm2 kana ichifamba kubva pa45 nm kuenda kune 5 nm process tekinoroji ichave inodhura zvakapetwa kashanu pamwero wemutengo chaiwo pachikamu chimwe chete. Nekudaro, kuitira kuchengetedza mari inogoneka mune zvehupfumi, processor machipisi anofanirwa kuve akanyanya compact. AMD iri kuita iyi thesis nekuchinja kune iyo inonzi "chiplets" - makristasi madiki akasanganiswa pane imwe substrate.
Slide yechitatu, yakatorwa nekamera yeblogger, inotaura nezvekugoverwa kwevatengi vemagetsi mumagadzirirwo emazuva ano ane chidimbu chekubatanidza. Chetatu chete chekushandiswa kwesimba kunokonzerwa nebasa rekuverenga. Izvo zvasara zvinotorwa kumusoro necache memory, yekuisa / kubuda logic, uye akasiyana mainterface. TDP mazinga e server CPUs uye maGPU akawedzera 2006% pagore kubva 7, maererano AMD. Kubudirira kwekushandiswa kwesimba hakuna kukwirira sezvatinoda.
