ISan Francisco ibike ukuthi namhlanje, i-AMD idedele ngokusemthethweni iprosesa lesizukulwane sesibili se-EPYC nge "aesthetics enobudlova" e-Art Palace yaseSan Francisco eneminyaka eyikhulu. Umkhiqizo we-chip chip codenamed "iRoma" akuyona i-chip ye-7nm X86 kuphela. Undunankulu womhlaba, kanye ne-AMD yokuqala edlula i-Intel kwinqubo, iguqule ukusebenza, ukwakhiwa kwezakhiwo nezindleko.
"Lesi yi-chip ye-X86 enamandla kakhulu emhlabeni, akekho noyedwa, senzele amarekhodi omhlaba angaphezu kwama-80! Sizophinda siguqe amazinga wesikhungo samanje sezinombolo futhi siqhubeke nokubhala kabusha imithetho yomdlalo emkhakheni wama-chip server." Esizukulwaneni sesibili uLong, engqungqutheleni yabezindaba, uMongameli we-AMD kanye ne-CEO uSu Zifeng akazange azisole ngokudumisa kwakhe.
I-chip ye-X86 enamandla kakhulu ebusweni
Ngonyaka owandulela ingqungquthela, isizukulwane sesibili seXiaolong "iRoma" sesidlulise imfudumalo emibili, ekhombisa ukulindelwa nokunakwa kwe-AMD.
Okokuqala, ngoNovemba wangonyaka odlule "I-Horizon Summit", "iRoma" yakwenza lokho. Okwesibili, eTaipei Computer Show ngoMeyi kulo nyaka, iRome yethulwa esigabeni sesithathu salo nyaka. Kungashiwo ukuthi ngaphandle kwentengo, ezinye izinhlaka eziyisisekelo zaseRoma azisolakali. .
Inqubo, ukwakhiwa kwezakhiwo kanye nezinzuzo zezindleko zingamalebula abalulekile we- "Roma". I-AMD ayitholanga nje ukwethulwa okokuqala kwe-7nm global X86 server chip, kodwa futhi yahola i-Intel okokuqala ngqa kule nqubo.
Inqubo ye-7nm iletha izinzuzo eziningi futhi ifinyelela ukuthuthuka okukhulu kokusebenza kahle, kufaka phakathi isilinganiso se-2x transistor, ukuncishiswa kwama-50% ukusetshenziswa kwamandla (ngaphansi kokusebenza okufanayo), kanye nokukhuphuka kokusebenza okungama-25% (ngaphansi kokusetshenziswa kwamandla okufanayo). Esikhaleni se-chip chip, ubungako obuphakathi, ukusebenza nokusetshenziswa kwamandla kuzoba izinkomba ezibaluleke kakhulu.
USu Zhifeng uthe "iRoma" iyi-chip enamandla kunazo zonke ku-X86 server chip yamanje, esebenza ngaphezu kwama-80 irekhodi, enganciphisa izindleko zizonke zobunikazi (i-TCO) ngo-50% ngaphansi kwemithwalo yemisebenzi ehlukahlukene.
"IRoma" isuselwa ekwakhiweni okusha kweZen 2. Ngokolwazi olukhishwe yi-AMD ku-COMPUTEX, ukwakhiwa kwezakhiwo zabathengi beZen 2 kungafinyelela ku-15% ukusebenza ngcono kwe-IPC uma kuqhathaniswa nokwakhiwa kwezizukulwane ezedlule. Ngaphezu kwalokho, ngokuya ngamamephu omgwaqo we-AMD, ukwakhiwa kobunikazi bezakhiwo Zen3 sekuphothuliwe, futhi ukwakhiwa kweZen4 kukulobo.
Iqhathaniswa nesizukulwane sokuqala se-AMD EPYC server chip "Naples", "iRoma" inganikeza ukusebenza kwezikhathi ezi-2 nge-slot ngayinye, kuze kube amahlandla ama-4 ukusebenza kokusebenza kwephuzu elintantayo. Ngokusho kwe-AMD, akukaze kube nokwenyuka okuphawuleka kangako emlandweni wama-server we-server.
I- "Roma" i-CPU eyodwa ingaba nezikhathini ezingama-64 zomzimba (okuyi-128 ezinengqondo). Iprosesa ngalinye linama-chips ayisishiyagalombili we-CPU akhiqizwa kwinqubo eyi-7nm, enamakhilogremu ayisishiyagalombili ahlanganisiwe ku-Die ngayinye. Isisekelo esingu-64 njengamanje siyisamba esikhulu kuma-server we-chip (i-Intel yakamuva ye-Xeon flagship chip 9282 inama-cores angama-56 kuphela).
Kuyaqondakala ukuthi "iRoma" yamukela ukwakheka okuhlenga "Chiplet". Ngenkathi une-computing basic Die Die, kukhona ne-I / O Die ezinikele, esebenzisa ubuchwepheshe inqubo inqubo ye-14nm futhi inesibopho sokulawula okufakwayo nokukhipha. Kuyaqondakala ukuthi i-I / O Die isebenzisa inqubo eyi-14nm esikhundleni se-7nm ngenxa yayo. Inenombolo enkulu yemijikelezo ye-analog, engabonakali futhi iyabiza uma inqubo ye-7nm isetshenziswa. Futhi ukwakheka okuyisisekelo kwe-modularity engu- "8 + 1" nakho kwenza ubunzima bokubekeka, izindleko, nokukhuphuka kwezithelo.
I-Roma EPYC ibuye ibe isigaba sokuqala se-X86 server-class CPU yokuxhasa ubuchwepheshe be-PCI-E 4.0, iphinda kabili isibalo seziteshi zebandwidth, ithuthukisa kakhulu ukusebenza kwe-accelerator, nekhadi elisha lokushesha i-Radeon Instinct MI60, nayo esekela i-PCI-E 4.0 ubuchwepheshe, kungaletha ukusebenza okungakaze kubonwe ngaphambili. Ngasikhathi sinye, noma ngabe kuyisizukulwane esikhona "i-Naples", noma isizukulwane sesibili se "Roma", nesizukulwane esilandelayo se- "Milan", i-EPYC (霄 龙) izosala isebenza endawenikazi, abasebenzisi bangathuthukisa ngomthungo.
Izindleko Zokusebenza Hammer Intel?
Isizukulwane sesibili sochungechunge lwe-Xiaolong processor "7002", amamodeli ayi-19, kufaka phakathi iziteshi ezi-14, iziteshi ezinhlanu zesiteshi esisodwa, imodeli yazo zombuso ezimbili yi-Xiaolong 7742, i-64 core 128 ngentambo, i-256MB-level ezintathu I-Cache, ireferensi ejwayelekile engu-2.25GHz, ukushesha kufinyelela ku-3.4GHz, ukusetshenziswa kwamandla kwamandla okwakha okwenziwe ngo-225W, kuze kufike ku-240W, ngentengo engu- $ 6950.
Njengabadlali ababili kuphela abaphambili ku-chip chip, i-AMD ne-Intel bebelokhu bekhona.
Engqungqutheleni ethi "Next Horizon" ngoNovemba nyakenye, i-AMD ikhombise ukuqhathanisa nesikhathi sokunikeza isithombe se-pixel esifanayo ne-EPYC yase-64-core kanye nama-chips amabili aphezulu we-Platinum Xeon 28-core Xeon Platinum 8180M. Imiphumela ikhombisa ukuthi i- "Roma" ithatha isikhathi esincane futhi ifinyelela "ukudlula okukodwa nendlela ephindwe kabili" ekusebenzeni.
Embukisweni wekhompyutha weTaipei ka-2019 ngoMeyi kulo nyaka, i-AMD iphinde yaqhathanisa "iRoma" ne-Intel's Xeon series 8280 chip. Ekuhlolweni kwe-NAMD (Molecular Dynamics High Performance Computing application), imiphumela ikhombisa ukuthi i-Intel 28 core Xeon Ukusebenza kwe-processor 8280 kuyinto i-9.68 ns / ngosuku, ngenkathi ukusebenza kwephrosesa le "Roma" kuphakeme njenge-19,60 ns / ngosuku , okubuye kwaphindeka kabili ukusebenza kwangaphambilini.
Emhlanganweni wanamuhla, i-AMD iphinde yasebenzisa isizukulwane sesibili se-Xiaolong flagship i-7742 ne-Intel Xeon Flagship 8280 ukukhombisa ukuqhathanisa nokulinganisa kokuqhathaniswa kwamangqamuzana. Imiphumela ikhombisa ukuthi eyedlule inezikhathi eziyi-1.6 zokuphucula ukusebenza.
Ngokuqondile, i-AMD "ilinganiswe" ngokuqondile iphume ngokuqondile ekuqhathanisweni kwentengo, uma kuqhathaniswa ne-28-msingi Intel Xeon 7742, i-EPYC yesizukulwane sesibili se-AMD ngaphansi kwesisekelo sokusebenza kabili, izindleko zingxenyeni yelinye iqembu.
Ukwakha kabusha amazinga wesikhungo sedatha yanamuhla
Esithangamini nabezindaba, uSu Zifeng uthe kusukela kwethulwa i-Snapdragon EPYC yokuqala "iNaples" ngonyaka we-2017 kuya esizukulwaneni sesibili samanje "iRoma", i-AMD izokhulisa inkumbulo kanye ne-I / O interface ngokujova ama-cores amaningi kulo mkhiqizo. Ezinye izindlela, okuholela kuzinguquko ezibalulekile ekusebenzeni okuholayo, amandla aphansi nezindleko, chaza izindinganiso zezikhungo zemakethe zezikhungo zemininingwane.

Isimo semvelo siyaqhubeka nokukhula. I-Google Twitter imemezela ukuthunyelwa
Selokhu kwethulwa ngokusemthethweni ukwakhiwa kwesakhiwo sokuqala seZen sesizukulwane sokuqala se-Snapdragon "Naples" ngonyaka we-2017, i-AMD ayikayifihli imigomo yayo kulo mkhakha. Ngaphandle kwesidingo sokusebenza komkhiqizo, ibuye ihlukaniswe kusuka ekuhlolweni kwemvelo okuphelele nokuningi. Ukusekelwa kwabalingani abaningi.
Ngokusekelwe esizukulwaneni sokuqala somprosesa we-EPYC, iprosesa lesizukulwane sesibili se-EPYC likhulise kakhulu ikamu le-AMD. Ngokusho kukaSu Zifeng, ukwakhiwa kwemvelo akukaze kubambezeleke ngenxa yokwamukelwa kwezinqubo ezintsha zobuchwepheshe, kepha kuqinisiwe.
Kuyaqondakala ukuthi i-AMD EPYC ecosystem inabalingani abangaphezu kwe-60. Le ndlela ebanzi yemvelo yabalingani ifaka abahlinzeki bemiklamo bangempela abanjengoGigabyte ne-QCT, nabathengisi bezingxenyekazi ezizimele (IHV) njenge-Broadcom, Micron neXilinx. Futhi ngathola ukwesekelwa ngabathengisi besistimu yokusebenza ye-Microsoft nabaningi beLinux. Izinhlelo ezisebenzayo ze-Linux njenge-Canonical, RedHat ne-SUSE ziye zabambisana ne-AMD ukuvivinya kakhulu nokuqinisekisa iprosesa lesizukulwane sesibili se-AMD EPYC kwizicelo zesikhungo sedatha. Lokhu kusize iprosesa lesizukulwane sesibili se-AMD EPYC ukuthi ibe ngaphezulu kwe-2x ipulatifomu yokuthuthuka kune-processor yesizukulwane sokuqala se-EPYC.
Engqungqutheleni yanamuhla, inqwaba yamakhasimende kanye nabalingani beza esiteji ne-AMD ukuzoxoxa ukuthunyelwa okusha kwe-AMD EPYC processor deployment.
Phakathi kwabo, iGoogle imemezele ukuthi bathumele inqubo yokuqhubekisela phambili isizinda se-AMD EPYC endaweni yesikhungo sokwakhiwa kwengqalasizinda yangaphakathi, futhi bazokweseka ikhompyutha entsha enenhloso esekwe kunqubo yesizukulwane sesibili se-AMD EPYC ku-Google Cloud Injini ngasekupheleni kuka-2019 I-Twitter iphinde yamemezela ukuthi bazothumela umshini wokuphrinta wesizukulwane sesibili se-AMD EPYC kwingqalasizinda yedatha kungekudala kulo nyaka, anciphise izindleko zobunikazi (i-TCO) ngama-25%. Ngaphezu kwalokho, kufaka iMicrosoft, HPE, Lenovo, Dell kanye nabanye abathengisi.
Imakethe ilindele ukuthi uchungechunge lwe-EPYC lusebenze kahle. Ikakhulu ngemuva kokuba kufakwe ohlwini lwesizukulwane sesibili seXiaolong "iRoma", i-AMD kulindeleke ukuthi ikhulise isabelo sayo semakethe enkundleni ye-server. Ngokusho kwe-Taiwan media Digitimes, i-AMD kulindeleke ukuthi ithole u-10% wesabelo semakethe ye-chip chip ngonyaka olandelayo.
U-Forrest Norrod, umongameli ophakeme kanye nomphathi ojwayelekile wesikhungo sedatha ye-AMD futhi wafaka izixazululo ezigxiliwe, uthe engxoxweni nabakwa-Episode kwiTraipei Computer Show yango-2019 iTaipei Computer Show ukuthi ngemuva kokwethulwa kweRome, izinga lokukhula kumele libe yinqaba ebusayo ngoba imiyalo eminingi iyabona isidingo esinamandla emakethe.
Ukubheka manje, ukwesekwa okuvela ezinhlobonhlobo zezinto zemvelo kubalulekile ekuphumeleleni kuchungechunge lwe-ECYC.
