San Francisco adanenanso kuti lero, AMD idatulutsira boma purosesa ya EPYC ya m'badwo wachiwiri ndi "aesthetics" achiwopsezo "mu Art Palace ya zaka 100 ku San Francisco. Seva chip product codenamed "Roma" si chipika cha 7nm X86 chokha. Pulogalamu yapadziko lonse lapansi, ndipo AMD yoyamba kupitirira Intel mchitidwewu, yasintha magwiridwe antchito, zomanga ndi mtengo.
"Ichi ndiye chipangizo cholimba kwambiri cha ma X86 padziko lonse lapansi, palibe aliyense, tapanga zolemba zapadziko lonse zoposa 80! Tidzasinthanso malingana ndi ziwerengero zamasiku ano ndikukapitilizanso kulemba malamulo a masewerawa pamasewera a ma seva." Kwa m'badwo wachiwiri Long, pamsonkhano wa atolankhani, Purezidenti wa AMD ndi CEO Su Zifeng sanadandaule poyamikiridwa.
Chip cholimba champhamvu cha X86 pamtunda
Chaka chatha msonkhano usanachitike, m'badwo wachiwiri wa Xiaolong "Rome" wadutsa kale maulendo awiri ofunda, omwe akuwonetsa kuyembekezera ndi chidwi cha AMD.
Choyamba, mu Novembala chaka chatha "Horizon Summit", "Roma" idayamba. Chachiwiri, pa Taipei Computer Show mu Meyi chaka chino, Rome idayambitsidwa gawo lachitatu la chaka chino. Titha kunena kuti kupatula mtengo wake, ma paramu ena oyambira ku Roma siwokayikitsa. .
Njira, zomangamanga ndi mapindu ake ndizofunikira kwambiri zolemba "Roma". AMD sikuti idangotulutsa koyamba kwa 7nm global X86 server chip, komanso idatsogolera Intel kwa nthawi yoyamba ikuchita.
Njira ya 7nm imabweretsa zabwino zambiri ndikukwaniritsa kukonza kwapamwamba kwambiri, kuphatikiza kachulukidwe ka 2x transistor, kuchepa kwa mphamvu ya 50% (pansi pa magwiridwe amodzimodzi), ndi 25% magwiridwe antchito (pansi pamagetsi omwewo). Mu danga la Chip seva, kuchuluka kwakukulu, magwiritsidwe ntchito ndi mphamvu yamagetsi ndizofunikira kwambiri.
Su Zhifeng adanena kuti "Roma" ndiye chipamwamba champhamvu kwambiri mu chipangizo cha seva cha X86, chokhala ndi mbiri yopitilira 80, chomwe chingachepetse mtengo wonse wa umwini (TCO) ndi 50% pansi pamitundu yambiri.
"Roma" ikhazikika pamangidwe watsopano wa Zen 2. Malinga ndi zomwe zatulutsidwa ndi AMD pa COMPUTEX, zomangamanga za Zen 2 za ogula zitha kukwanitsa mpaka 15% IPC magwiridwe antchito poyerekeza ndi kamangidwe kam'mbuyomu. Kuphatikiza apo, malinga ndi mseu wa AMD, mapangidwe a zomangamanga a Zen3 adamalizidwa, ndipo kapangidwe ka Zen4 ndi kapangidwe kake.
Poyerekeza m'badwo woyamba wa AMD EPYC seva chip "Naples", "Roma" ikhoza kupereka maulendo a 2 pa slot iliyonse, mpaka kanayi magwiridwe antchito akuyenda. Malinga ndi AMD, sipanakhalepo chiwonjezeko chachikulu chotere m'mbiri ya tchipisi cha seva.
"Roma" CPU yokhayo imatha kukhala ndi ma pores 64 a thupi (128 zomveka). Purosesa iliyonse imakhala ndi tchipisi zisanu ndi zitatu za CPU zopangidwira mu 7nm, ndipo masamba asanu ndi atatu ophatikizika mu Die. Pakatikati pa 64 pakadali pano pali chiwerengero chachikulu cha ma seva tchipisi (Intel's Xeon flagship chip 9282 yaposachedwa chili ndi ma cores 56).
Zimamveka kuti "Roma" amatengera kapangidwe ka "Chiplet" kosintha. Ngakhale tili ndi kompyuta yoyambira odzipatulira ya Die, palinso I / O Die yodzipereka, yomwe imagwiritsa ntchito ukadaulo wa 14nm waukadaulo ndipo imayang'anira zowongolera ndi zotulutsa. Zimamveka kuti I / O Die imagwiritsa ntchito 14nm m'malo mwa 7nm chifukwa cha iyo. Muli ndi magulu ambiri a mabulogu a analog, omwe sakudziwika komanso okwera mtengo ngati njira ya 7nm yagwiritsidwa ntchito. Ndipo kapangidwe koyambirira kamasinthidwe amtundu wa "8 + 1" kameneka kumathandizanso kuti zovuta zizikhala zovuta, mtengo, komanso kukolola.
