Namuhla ekuvulweni kweComputex 2019, i-AMD yethule i-7nm isizukulwane sesithathu se-Ryzen processors (Matisse) ebesilindelwe isikhathi eside. Uhlu lwemikhiqizo emisha esekelwe ku-Zen 2 microarchitecture ihlanganisa amamodeli amahlanu okucubungula, kusukela ku-$200 kanye ne-5-core Ryzen 500 kuya ku-$9 Ryzen 7 chips anama-cores ayishumi nambili. Ukuthengiswa kwemikhiqizo emisha, njengoba bekulindelekile, kuzoqala ngoJulayi 570 walo nyaka. Kanye nabo, amabhodi omama asekelwe ku-chipset ye-XXNUMX nawo azofika emakethe.
Ukukhishwa kwe-Ryzen 3000 processors, okusekelwe ku-Zen 2 microarchitecture, kubukeka sengathi kuzoba ushintsho lwe-tectonic ngempela emakethe ye-PC. Uma sibheka imininingwane eyethulwe yi-AMD namuhla esethulweni, inkampani ihlose ukubamba ubuholi futhi ibe ngumkhiqizi wamaphrosesa athuthuke kakhulu kwezobuchwepheshe bezinhlelo zemakethe enkulu. Lokhu kufanele kakhulu kwenziwe lula ubuchwepheshe obusha be-TSMC 7nm, obusetshenziswa ekwenzeni i-Ryzen yesizukulwane sesithathu. Ngenxa yalokho, i-AMD yakwazi ukuxazulula izinkinga ezimbili ezibalulekile: ukunciphisa kakhulu ukusetshenziswa kwamandla kwama-chips asebenza kahle, futhi kubenze bathengeke.
I-Zen 2 microarchitecture entsha kufanele futhi ibe negalelo elikhulu empumelelweni ye-Ryzen entsha. Ngokwezithembiso ze-AMD, ukunyuka kwe-IPC (ukusebenza ngewashi ngalinye) uma kuqhathaniswa ne-Zen+ kube ngu-15%, kuyilapho ama-processor amasha ezokwazi ukusebenza amaza aphezulu. Futhi phakathi kwezinzuzo ze-Zen 2 ukukhuphuka okuphawulekayo kwevolumu yenqolobane yezinga lesithathu kanye nokuthuthukiswa okuphindwe kabili ekusebenzeni kweyunithi yenombolo yangempela (i-FPU).
Kanye nokuthuthukiswa kwe-microarchitecture, i-AMD iphinde inikeze inkundla entsha ye-X570, okufanele inikeze ukwesekwa kwe-PCI Express 4.0, ibhasi eline-bandwidth ephindwe kabili. Amabhodi omama we-Socket AM4 amadala azothola ukwesekwa kwamaphrosesa amasha ngezibuyekezo ze-BIOS, kodwa ukusekelwa kwe-PCI Express 4.0 kuzonqunyelwa.
Kodwa-ke, kubonakala sengathi isikhali esikhulu se-AMD kulesi sigaba sisazoba amanani entengo. Inkampani izolandela inqubomgomo yamanani enolaka, engqubuzana ngokuphelele nalokho i-Intel esifundise ukuba sikwenze. Kungenzeka ukuthi inqubo ye-7-nm kanye nokusetshenziswa kwama-chiplets kuye kwavumela i-AMD ukuba izuze kakhulu ezindlekweni zomkhiqizo, ngenxa yokuthi ukuncintisana emakethe yokucubungula kuzoqina ngamandla angakaze abonwe.
| AmaCongo/Imicu | Imvamisa yesisekelo, GHz | Imvamisa ye-Turbo, GHz | L2 inqolobane, MB | L3 inqolobane, MB | I-TDP, Вт | Izindleko | |
|---|---|---|---|---|---|---|---|
| I-Ryzen 9 3900X | 12/24 | 3,8 | 4,6 | 6 | 64 | 105 | $499 |
| I-Ryzen 7 3800X | 8/16 | 3,9 | 4,5 | 4 | 32 | 105 | $399 |
| I-Ryzen 7 3700X | 8/16 | 3,6 | 4,4 | 4 | 32 | 65 | $329 |
| I-Ryzen 5 3600X | 6/12 | 3,8 | 4,4 | 3 | 32 | 95 | $249 |
| I-Ryzen 5 3600 | 6/12 | 3,6 | 4,2 | 3 | 32 | 65 | $199 |
Iprosesa ephezulu ohlwini lwesithathu lwesizukulwane se-Ryzen, i-AMD ememezele namuhla, iphenduke i-Ryzen 9 3900X. Lena iprosesa esekelwe kuma-chiplets amabili e-7nm, inkampani ezophikisana nochungechunge lwe-Intel Core i9. Ngasikhathi sinye, namuhla azikho ezinye izindlela zale chip enezici ezifanayo, kungaba ezivela koqhudelana naye noma ezivela ku-AMD uqobo, ngoba lena yi-CPU yokuqala ekhiqizwa ngobuningi emlandweni enama-cores ayi-12 nemicu engama-24. I-chip ine-TDP ye-105 W, intengo yokuncintisana kakhulu ye-$ 499, namafrikhwensi we-3,8-4,6 GHz. Ingqikithi yenkumbulo yenqolobane yesilwane esinjalo izoba ngu-70 MB, ne-L3 cache accounting engu-64 MB.
Uchungechunge lwe-Ryzen 7 luhlanganisa amaphrosesa amabili we-7-core kanye nentambo eyishumi nesithupha eyakhelwe kusetshenziswa i-chiplet ye-7nm eyodwa. I-Ryzen 3800 105X ine-3,9W TDP kanye nesivinini sewashi esingu-4,5-399GHz ngo-$7, kuyilapho i-Ryzen 3700 3,6X ehamba kancane ine-TDP engu-4,4-65GHz, i-329W TDP kanye nethegi yentengo engu-$32. Inqolobane yezinga lesithathu yawo womabili ama-processor ayisishiyagalombili anomthamo ongu-XNUMX MB.
Uchungechunge lwe-Ryzen 5 luhlanganisa ama-processor amabili anama-cores ayisithupha nemicu eyishumi nambili. Imodeli endala, i-Ryzen 5 3600X, ithole amafrikhwensi angu-3,8–4,4 GHz kanye nephakheji eshisayo engu-95 W, kanti amaza emodeli encane i-Ryzen 5 3600 angu-3,6–4,2 GHz, azoyivumela ukuthi ingene ngaphakathi kwephakheji eshisayo 65 w. Izintengo zamaphrosesa anjalo zizoba ngu-$249 no-$199, ngokulandelana.
Esethulweni, i-AMD inake kakhulu ukusebenza kwemikhiqizo yayo emisha. Ngakho-ke, inkampani ithi i-12-core flagship yayo entsha i-Ryzen 9 3900X ishesha ngo-60% kune-Core i9-9900K ekuhlolweni okunemicu eminingi kwe-Cinebench R20, kanye no-1% ngokushesha kunenye indlela ye-Intel ekuhlolweni okunochungechunge olulodwa. Kodwa-ke, uma kubhekwa inani elikhulayo lama-cores, lesi silinganiso semiphumela sinengqondo impela.
Kodwa-ke, i-AMD iphinde yathi i-Ryzen 9 3900X iyakwazi ukwedlula iphrosesa ye-HEDT engu-12-core HEDT, i-Core i9-9920X, ngentengo engu-$1200. Inzuzo yokunikezwa kwe-AMD ku-Cinebench R20 enemicu eminingi ingu-6%, kanti ngomucu owodwa ingu-14%.
I-Ryzen 9 9920X entsha iphinde yakhombisa inzuzo ekholisayo ngaphezu kwe-Core i9-3900X ku-Blender.
Uma ukhuluma ngokusebenza kwe-7-core Ryzen 3800 2080X, i-AMD igxile ekusebenzeni kwemidlalo, futhi ihlaba umxhwele ngempela. Ngokusho kokuhlolwa okwethulwe i-AMD ngekhadi levidiyo le-GeForce RTX 7, ukuthuthuka kwamazinga ozimele emidlalweni edumile uma kuqhathaniswa ne-2700-core Ryzen 11 34X yangaphambilini endala isukela ku-XNUMX kuya ku-XNUMX%.
Kubonakala sengathi lokhu kungavumela ama-chips e-AMD ukuthi asebenze kanye nama-Intel processors ngaphansi kwemithwalo yemidlalo. Okungenani uma kuboniswa i-Ryzen 7 3800X Ezinkundleni Zempi ze-PlayerUnknown, le processor ibonise izilinganiso zozimele ezifanayo ne-Core i9-9900K.
Endleleni, i-AMD iphinde yaziqhenya ngokusebenza okuphezulu kwamaphrosesa ayo ayisishiyagalombili ku-Cinebench R20. Esivivinyweni esinemicu eminingi, i-Ryzen 7 3800X ikwazile ukudlula i-Core i9-9900K ngo-2%, futhi ekuhlolweni okucushwe okukodwa ngo-1%.
Uma i-Ryzen 7 3700X iqhathaniswa ne-Core i7-9700K, inzuzo ekusebenzeni okunemicu eminingi ingu-28%. Ngasikhathi sinye, sikhumbula ukuthi ukushisa okuvamile kwe-Ryzen 7 3700X kungu-65 W, kuyilapho ama-Intel processors okwenziwa ngawo isiqhathaniso ayingxenye yephakheji ye-thermal ye-105-watt. Imodeli esheshayo ye-Ryzen 7 3800X ene-TDP ye-105 W ilindeleke ngaphambi kwe-Core i7-9700K nakakhulu - ngo-37% ekuhlolweni okunezintambo eziningi.
Ekugcineni, ukwethulwa kwama-chips e-AMD kubangele imvuselelo ephawulekayo phakathi kwabashisekayo. Kodwa-ke, kufanelekile ukuqaphela ukuthi imininingwane eminingi ayikakacaci. Ngeshwa, inkampani ayizange ichaze ukuthi ukugxuma okubaluleke kangaka ekusebenzeni kuvela kuphi. Siyazi ukuthi i-Zen 2 ihlanganisa ukuthuthukiswa kokubikezela kwegatsha, ukulanda kuqala imiyalelo, ukulungiselelwa kwenqolobane yemiyalo, ukwanda kokusebenza kanye nokubambezeleka okuphansi ebhasini le-Infinity Fabric, kanye nezinguquko kumklamo wenqolobane yedatha. Ukwengeza, imininingwane ephathelene namandla okudlula ngokweqile ayicacile, okungekho imininingwane ngayo nhlobo okwamanje. Sithemba ukuthi imininingwane ecacile izocaca eduze nesimemezelo.
"Ukuze ube umholi wezobuchwepheshe, kufanele ubheje kakhulu," kusho uLisa Su, isikhulu esiphezulu se-AMD, enkulumweni yakhe eyisihluthulelo yeComputex 2019. Futhi ukubheja okwenziwe yinkampani ebomvu namuhla kuzokwehlulwa yi-Intel mancane amathuba okuthi kuphumelele.
