Nhasi pakuvhurwa kweComputex 2019, AMD yakaunza yakamirirwa kwenguva refu 7nm yechitatu chizvarwa Ryzen processors (Matisse). Mutsara wezvigadzirwa zvitsva zvakavakirwa paZen 2 microarchitecture inosanganisira mashanu processor modhi, kubva pamadhora mazana maviri uye matanhatu-musimboti Ryzen 200 kusvika kumadhora mazana mashanu eRyzen 5 machipi ane gumi nemaviri cores. Kutengeswa kwezvinhu zvitsva, sezvaimbotarisirwa, kuchatanga muna Chikunguru 500 wegore rino. Pamwe chete navo, mamaboards akavakirwa paX9 chipset achauyawo kumusika.
Kuburitswa kweiyo Ryzen 3000 processors, yakavakirwa paZen 2 microarchitecture, inoita sekunge ichave yechokwadi tectonic shanduko mumusika wePC. Tichitarisa neruzivo rwakaratidzwa ne AMD nhasi pakuratidzwa, kambani inotarisira kubata hutungamiriri uye kuva mugadziri weakanyanya tekinoroji processors emisika-yemusika masisitimu. Izvi zvinofanirwa kufambiswa zvakanyanya neiyo itsva TSMC 7nm process tekinoroji, iyo inoshandiswa mukugadzira yechitatu chizvarwa Ryzen. Kutenda kwazviri, AMD yakakwanisa kugadzirisa matambudziko maviri akakosha: kudzikisa zvakanyanya kushandiswa kwesimba kwemachipisi epamusoro-soro, uye zvakare kuita kuti ive inokwanisika.
Iyo itsva Zen 2 microarchitecture inofanirawo kubatsira zvakanyanya mukubudirira kweRyzen itsva.Sekureva kwezvivimbiso zve AMD, kuwedzera kweIPC (kuita pawachi) zvichienzaniswa neZen+ kwaive 15%, ukuwo ma processor matsva achakwanisa kushanda ma frequency epamusoro. Zvakare pakati pezvakanakira Zen 2 kuwedzera kukuru kwevhoriyamu yechitatu nhanho cache uye kaviri kuvandudzwa mukuita kweiyo chaiyo nhamba unit (FPU).
Pamwe chete nekuvandudzwa kwe microarchitecture, AMD iri kupawo itsva X570 chikuva, iyo inofanirwa kupa rutsigiro rwePCI Express 4.0, bhazi rine kaviri bandwidth. Ekare Socket AM4 mamabhodhi achawana rutsigiro rwema processor matsva kuburikidza neBIOS zvigadziriso, asi rutsigiro rwePCI Express 4.0 ruchaganhurwa.
Nekudaro, zvinoita sekunge chombo chikuru che AMD panguva ino chicharamba chiri mutengo. Iyo kambani ichaomerera kune yakanyanya hutsinye mutemo wemitengo, uyo unopokana zvachose nezvatakadzidziswa neIntel kuita. Zvingangodaro kuti iyo 7-nm maitiro uye kushandiswa kwechiplets kwakabvumira AMD kuwana zvakanyanya mumitengo yezvigadzirwa, nekuda kweiyo makwikwi mumusika we processor achawedzera nesimba risati ramboitika.

Iyo yepamusoro processor muchizvarwa chechitatu Ryzen lineup, iyo AMD yakazivisa nhasi, yakave iyo Ryzen 9 3900X. Iyi i processor yakavakirwa pambiri 7nm chiplets, iyo kambani iri kuzopokana neIntel Core i9 yakatevedzana. Panguva imwecheteyo, nhasi hapana dzimwe nzira dzechip iyi dzine hunhu hwakafanana, ingave kubva kumukwikwidzi kana kubva ku AMD pachayo, nekuti iyi ndiyo yekutanga-yakagadzirwa CPU munhoroondo ine gumi nemaviri cores uye 12 tambo. Iyo chip ine TDP ye24 W, mutengo wakakwikwidza wemadhora mazana mana nemakumi mapfumbamwe nemapfumbamwe, uye ma frequency e105-499 GHz. Iyo yakazara cache ndangariro yechikara chakadaro ichave 3,8 MB, ine L4,6 cache accounting ye70 MB.
Iyo Ryzen 7 yakatevedzana inosanganisira maviri masere-musimboti uye gumi nematanhatu-tambo processors akavakwa achishandisa imwechete 7nm chiplet. Iyo Ryzen 7 3800X ine 105W TDP uye 3,9-4,5GHz wachi inomhanya yemadhora mazana matatu nemakumi matatu, nepo iyo inononoka zvishoma Ryzen 399 7X ine 3700-3,6GHz TDP, 4,4W TDP uye mutengo we $65. Yechitatu nhanho cache yeese sere-core processors ine huwandu hwe329 MB.
Iyo Ryzen 5 yakatevedzana inosanganisira maviri processors ane matanhatu cores uye gumi nembiri tambo. Iyo yekare modhi, Ryzen 5 3600X, yakagamuchira ma frequency e3,8-4,4 GHz uye thermal package ye95 W, uye ma frequency eiyo mudiki modhi Ryzen 5 3600 ndeye 3,6-4,2 GHz, iyo inozoibvumira kuti ikwane mukati meiyo inopisa pasuru ye 65 W . Mitengo yema processor akadaro ichave $249 uye $199, zvichiteerana.
Pamharidzo, AMD yakatarisisa zvakanyanya pakuita kwezvigadzirwa zvayo zvitsva. Nekudaro, iyo kambani inoti yayo nyowani 12-musimboti mureza Ryzen 9 3900X iri 60% nekukurumidza kupfuura iyo Core i9-9900K mune yakawanda-yakarukwa yeCinebench R20 bvunzo, uye 1% nekukurumidza kupfuura Intel imwe nzira muyedzo ine tambo imwe chete. Nekudaro, nekupihwa kwakawedzera nhamba yemacores, iyi reshiyo yemhedzisiro ine musoro.
Nekudaro, AMD yakataurawo kuti iyo Ryzen 9 3900X inokwanisa kukunda mukwikwidzi's 12-core HEDT processor, iyo Core i9-9920X, nemutengo wemadhora chiuru nemazana maviri. Mukana wekupihwa kwe AMD mune yakawanda-yakarukwa Cinebench R1200 ndeye 20%, uye mune imwechete-tambo ndeye 6%.
Iyo itsva Ryzen 9 9920X yakaratidzawo mukana unogutsa pamusoro peCore i9-3900X muBlender.
Kana tichitaura nezve kuita kweiyo sere-musimboti Ryzen 7 3800X, AMD yakatarisana nekuita kwemitambo, uye inoshamisa chaizvo. Zvinoenderana nemiedzo yakaunzwa iyo AMD yakaitisa neGeForce RTX 2080 kadhi yevhidhiyo, kuvandudzwa kwemafiremu mumitambo yakakurumbira zvichienzaniswa neyekare sere-musimboti Ryzen 7 2700X kubva pa11 kusvika 34%.
Zvinoita sekuti izvi zvinogona kubvumira AMD machipi kuita pamwe neIntel processors pasi pemitambo mitoro. Zvirinani kana ichiratidza iyo Ryzen 7 3800X muPlayerUnknown's Battlegrounds, processor iyi yakaratidza mareti akafanana neCore i9-9900K.
Vari munzira, AMD zvakare yakazvikudza nezvekushanda kwepamusoro kweayo masere-musimboti processors muCinebench R20. Muyedzo ine tambo dzakawanda, iyo Ryzen 7 3800X yakakwanisa kudarika Core i9-9900K ne2%, uye mune imwechete-tambo bvunzo ne1%.
Kana iyo Ryzen 7 3700X ichifananidzwa neCore i7-9700K, ipapo mukana wekuita-wakawanda-tambo kuita 28%. Panguva imwecheteyo, tinoyeuka kuti yakajairika kupisa kupisa kweRyzen 7 3700X ndeye 65 W, nepo maIntel processors ari kuenzanisa nawo ari e105-watt thermal package. Iyo inokurumidza Ryzen 7 3800X modhi ine TDP ye105 W inotarisirwa pamberi peCore i7-9700K zvakatonyanya kukosha - ne37% muyedzo ine tambo dzakawanda.
Pakupedzisira, kuunzwa kwemachipi e AMD kwakakonzera rumutsiriro rwunooneka pakati pevanofarira. Nekudaro, zvakakosha kuti ticherechedze kuti zvakawanda zvakawanda zvichiri kujeka. Nehurombo, kambani haina kutsanangura kuti kusvetuka kwakakosha kwakadaro mukuita kunobva kupi. Isu tinoziva kuti Zen 2 inosanganisira kuvandudzwa kwebazi rekufungidzira, kuraira kufanotungamira, kuraira cache optimizations, yakawedzera throughput uye yakaderera latency paInfinity Fabric bhazi, uye shanduko kune data cache dhizaini. Uye zvakare, iwo ruzivo nezve iyo overclocking kugona haina kujeka, pamusoro payo pasati pave neruzivo zvachose. Tinovimba kuti mamwe mashoko chaiwo achajeka pedyo nechiziviso.
"Kuti uve mutungamiri wezvigadzirwa zvemichina, unofanirwa kubheta hombe," akadaro Lisa Su, mukuru mukuru we AMD, muhurukuro yake inokosha yeComputex 2019. Uye bheti iyo kambani tsvuku yakaita nhasi ichabviswa neIntel haigoni kubudirira.
