Mukupera kwesvondo rapfuura, U.S. Department of Commerce Makambani eAmerica kushandira pamwe nemakambani mashanu eChinese nemasangano, uye panguva ino rondedzero yezvirango yaisanganisira maviri AMD mabatiro akabatanidzwa, pamwe nekombuta uye server inogadzira Sugon, iyo ichangotanga kugadzirira zvigadzirwa zvayo ne "clones" ane marezinesi e AMD processors. chizvarwa chekutanga Zen architecture. Vamiriri ve AMD vakaratidza kugadzirira kwavo kuzviisa pasi pezvido zvevakuru veAmerica, asi kusvika pari zvino havasati vataura chero chinhu chakasimba nezve kumwe kubatirana nevadyidzani veChinese.
Clones eEPYC neRyzen processors, ayo anogadzirwa kunze kweChina nekuraira kweHygon, akatoonekwa munhau dzedu mukupera kwemwedzi wapfuura. Aya ma processor akagadzirwa pasi perezinesi kubva ku AMD, iyo yaakapa kune vekuChina vadyidzani nemadhora mazana maviri nemakumi mapfumbamwe nematatu emadhora, panguva imwe cheteyo vachiwana 293% yezvikamu muHaiguang Microelectronics Co joint venture, uye 51% yezvikamu muChengdu Haiguang Integrated Circuit Design bhizinesi, iyo inodaidzira inovandudza processors pasi peiyo AMD rezinesi. Nekudaro, iyo data iripo pane hunhu uye masikirwo eHygon brand processors anotibvumira kutaura kuti ivo vanosiyana kubva kuAmerican prototypes kunyanya nerutsigiro rwavo rwe data encryption algorithms yakanangana neChina.
Maererano nebhuku racho , kwaive kusabatanidzwa kwe data encryption blocks kubva kumarezinesi akaendeswa kumaChinese ayo pane imwe nguva akabvumira AMD kudzivirira kuwedzera kutarisisa kwezviremera zveAmerica pakubata neITHIC. Zviremera zvine hunyanzvi zveUS zvine godo nekutengeswa kunze kwenyika tekinoroji, uye kugona kwevanoshanda navo veChinese kugadzira yakakwira-performance server processors kuchawedzera makwikwi mumusika wepasi rose wesupercomputer masisitimu. Zvinowanzogamuchirwa kuti chikonzero chepamutemo chekurambidzwa kwemazuva ano kwekushandira pamwe neSugon kwaive kutaura kwekambani pamusoro pezvinangwa zvayo zvekushandisa server masisitimu emhando iyi kusangana nedziviriro yePRC.
Mamwe masangano ehurumende yeUS pakutanga haana kufarira chirongwa che AMD chekugadzira mubatanidzwa nemaChinese. Lisa Su akaenda kunhaurirano nevakuru veChinese chaizvo mumwedzi wake wekutanga semukuru we AMD, uye muna Kukadzi 2016 chibvumirano chakapedzwa. Sezvatinoziva ikozvino, AMD haina kutora chikamu mune aya mabhizimusi nemari, asi yakapa chete kodzero dzezvivakwa zvehungwaru. Dhipatimendi reDziviriro reUS rakatoedza kumanikidza AMD kubvumidza chibvumirano kuburikidza neKomiti Yezvekudyara Kwekunze, asi kambani iyi yakapokana kuramba kwayo nekuda kwezvikonzero zvakati. Kutanga, akapokana kuti chimiro chakadaro chemubatanidzwa chaive chisiri pasi pekutenderwa kubvumidzwa neKomiti. Kechipiri, yakataura kuti yakanga isiri kuendesa matekinoroji emazuva ano kuPRC. Chechitatu, yakabvisa kubva kune rezinesi mukana wevaChinese vanodyidzana vachishandisa processor mayunitsi ane basa re encryption data.
Zviremera zveAmerica zvaishushikanawo nekunyongana kwevaridzi chimiro chemubatanidzwa wakagadzirwa ne AMD nedivi reChinese. Kambani yeAmerica yakataura kuti chimiro chakadaro chakagadzirirwa kufunga nezvezvido zveChinese vanobatana, asi panguva imwe chete hazvipokane nemitemo yeUS. Semuenzaniso, kambani iyo AMD yaidzora isingapfuure makumi matatu muzana yemasheya yaive nebasa rekuvandudza ma processors mumubatanidzwa. Izvi zvakabvumira zviremera zveChinese kuti zvitarise maHygon processors se "budiriro yemumba", iyo yakatotaurwa pachivharo chavo - "yakagadzirwa muChengdu". Padivi payo ndeye "yakagadzirwa muChina" chitambi, kunyangwe zviri pachena kuti AMD vekuChina vanobatana vanongoisa maodha ekugadzirwa kweava ma processor, uye anogona kunge anogadzirwa neGlobalFoundries kumafekitori avo muUSA kana Germany.
AMD inosimbisa kuti kunyangwe isati yapedza chibvumirano neITHIC, muna 2015, zvishoma nezvishoma uye zvakadzama yakazivisa zviremera zvine hunyanzvi nezvekufambira mberi kwenhaurirano, asi havana kuwana zvipingamupinyi zvakakomba pakugadzirwa kwemubatanidzwa uye kuendesa rezinesi. yekuvandudza kwe x86-inoenderana processors. Nyanzvi dzinotenda kuti pasina rubatsiro rwe AMD uye vamwe vekuAmerican vanobatana, iyo yeChinese side haigone kugadzira ma processor ane Zen architecture nekusingaperi. Zvimwe zvemazuva ano AMD zvivakwa hazvina kuendeswa kune vagadziri veChinese kuti vashandise pasi peichi chibvumirano. Muchikamu chekutanga chegore rino, AMD yakakwanisa kugashira madhora makumi matanhatu emamiriyoni emari yerezinesi kubva kuvashandi vekuChina, pavakatanga kugadzira maHygon processors emaseva nenzvimbo dzekushandira. Zvinoenderana nechibvumirano, havafanirwe kutengeswa kunze kweChina, asi iko zvino zviremera zveUS zvinoona kutyisidzira kuchengetedzeka kwenyika kunyangwe mukushandiswa kwema processors mukati meChina.
Izvo zvakakosha kuti AMD yakakudza kuburitswa kweThe Wall Street Journal neyakasiyana chirevo pamapeji . Kambani iyi yakati yatora matanho anodiwa kudzivirira kushandiswa zvisizvo kwetekinoroji uye budiriro inoendeswa kudivi reChinese, pamwe nekuita kuti zvisaite "kudzosera mainjiniya" kuitira kuti vazvimirire kusimudzira zvizvarwa zvinotevera zveChinese processors. Kubva 2015, kambani yakanyatso kurongedza zviito zvayo nemadhipatimendi akakodzera eAmerica, uye havana kuwana chikonzero chekurambidza kugadzirwa kwemubatanidzwa nevadyidzani veChinese. Iwo matekinoroji akaendeswa kumaChinese, sekureva kwake, akaita kuti zvikwanisike kugadzira ma processor aive akaderera mukumhanya kune zvimwe zvigadzirwa zviripo pamusika panguva iyo chibvumirano chakapedzwa. AMD ikozvino inoshanda zvakanyatsoenderana nemutemo weAmerica, uye haibvumire kuendesa tekinoroji kumakambani anosanganisirwa murondedzero yezvirango, uye yakamisawo kutengeserana kuchinjana navo.
