Lero pakutsegulira kwa Computex 2019, AMD idakhazikitsa ma processor a Ryzen (Matisse) omwe akuyembekezeredwa kwanthawi yayitali a 7nm. Mndandanda wazinthu zatsopano kutengera Zen 2 microarchitecture imaphatikizapo mitundu isanu ya purosesa, kuyambira $200 ndi zisanu ndi chimodzi za Ryzen 5 mpaka $500 Ryzen 9 chips yokhala ndi ma cores khumi ndi awiri. Kugulitsa zinthu zatsopano, monga momwe amayembekezera kale, kudzayamba pa Julayi 7 chaka chino. Pamodzi ndi iwo, ma boardards otengera X570 chipset adzabweranso kumsika.
Kutulutsidwa kwa mapurosesa a Ryzen 3000, kutengera Zen 2 microarchitecture, kumawoneka ngati kudzakhala kusintha kwenikweni pamsika wa PC. Potengera zomwe AMD idapereka lero pa chiwonetserochi, kampaniyo ikufuna kulanda utsogoleri ndikukhala wopanga mapurosesa apamwamba kwambiri paukadaulo wamsika wamsika. Izi ziyenera kuthandizidwa kwambiri ndi ukadaulo watsopano wa TSMC 7nm, womwe umagwiritsidwa ntchito popanga Ryzen m'badwo wachitatu. Chifukwa cha izo, AMD adatha kuthetsa mavuto awiri ofunikira: kuchepetsa kwambiri kugwiritsira ntchito mphamvu kwa tchipisi tapamwamba kwambiri, komanso kuwapangitsa kukhala otsika mtengo.
Zomangamanga zatsopano za Zen 2 ziyeneranso kuthandizira kwambiri kuti Ryzen yatsopano ikhale yabwino.Molingana ndi malonjezo a AMD, kuwonjezeka kwa IPC (machitidwe pa wotchi) poyerekeza ndi Zen + kunali 15%, pomwe mapurosesa atsopano azitha kugwira ntchito ma frequency apamwamba. Komanso pakati pa zabwino za Zen 2 ndikuwonjezeka kwakukulu kwa voliyumu ya cache yachitatu komanso kuwongolera kawiri pakuchita kwa nambala yeniyeni (FPU).
Pamodzi ndi kukonza kwa zomangamanga zazing'ono, AMD ikuperekanso nsanja yatsopano ya X570, yomwe iyenera kupereka chithandizo kwa PCI Express 4.0, basi yokhala ndi bandwidth kuwirikiza kawiri. Mabotolo akale a Socket AM4 adzalandira chithandizo cha mapurosesa atsopano kudzera muzosintha za BIOS, koma chithandizo cha PCI Express 4.0 chidzakhala chochepa.
Komabe, zikuwoneka kuti chida chachikulu cha AMD pakadali pano chikhalabe mitengo. Kampaniyo itsatira mfundo zamtengo wapatali kwambiri, zomwe zimasemphana ndi zomwe Intel watiphunzitsa kuchita. Zikuoneka kuti ndondomeko ya 7-nm ndi kugwiritsa ntchito ma chipset alola AMD kuti ipindule kwambiri pamtengo wamtengo wapatali, chifukwa chomwe mpikisano mumsika wa processor udzakulirakulira ndi mphamvu zomwe sizinachitikepo.

Purosesa wamkulu mum'badwo wachitatu wa Ryzen mzere, womwe AMD idalengeza lero, idakhala Ryzen 9 3900X. Ichi ndi purosesa yochokera pa ma chipset awiri a 7nm, omwe kampaniyo ikutsutsana ndi mndandanda wa Intel Core i9. Panthawi imodzimodziyo, lero palibe njira zina za chipangizochi chokhala ndi makhalidwe ofanana, mwina kuchokera kwa mpikisano kapena kuchokera ku AMD yokha, chifukwa iyi ndi CPU yoyamba yopangidwa ndi misala m'mbiri ndi 12 cores ndi 24 ulusi. Chip ili ndi TDP ya 105 W, mtengo wampikisano kwambiri wa $ 499, ndi ma frequency a 3,8-4,6 GHz. Chikumbukiro chonse cha cache cha chilombo chotere chidzakhala 70 MB, ndi cache ya L3 yowerengera 64 MB.
Mndandanda wa Ryzen 7 umaphatikizapo ma processor awiri apakati ndi khumi ndi asanu ndi limodzi opangidwa pogwiritsa ntchito chiplet chimodzi cha 7nm. Ryzen 7 3800X ili ndi 105W TDP ndi 3,9-4,5GHz wotchi yothamanga $399, pamene Ryzen 7 3700X yocheperako ili ndi 3,6-4,4GHz TDP, 65W TDP ndi mtengo wa $329. Chosungira chachitatu cha ma processor onse asanu ndi atatu ali ndi mphamvu ya 32 MB.
Mndandanda wa Ryzen 5 umaphatikizapo mapurosesa awiri okhala ndi ma cores asanu ndi limodzi ndi ulusi khumi ndi awiri. Mtundu wakale, Ryzen 5 3600X, udalandira ma frequency a 3,8-4,4 GHz ndi phukusi lotenthetsera la 95 W, ndipo ma frequency a Ryzen 5 3600 wachichepere ndi 3,6-4,2 GHz, omwe angalole kuti agwirizane ndi phukusi lotentha la 65W ndi. Mitengo ya mapurosesa amenewa adzakhala $249 ndi $199, motero.
Pachiwonetsero, AMD idapereka chidwi kwambiri pakuchita kwazinthu zake zatsopano. Chifukwa chake, kampaniyo imati chikwangwani chake chatsopano cha 12-core Ryzen 9 3900X ndi 60% mwachangu kuposa Core i9-9900K pamayeso amtundu wa Cinebench R20, ndi 1% mwachangu kuposa njira ya Intel pamayeso amtundu umodzi. Komabe, chifukwa cha kuchuluka kwa ma cores, chiŵerengero ichi cha zotsatira ndichomveka.
Komabe, AMD idatinso Ryzen 9 3900X imatha kupitilira purosesa ya 12-core HEDT ya mpikisano, Core i9-9920X, ndi mtengo wa $1200. Ubwino wa zopereka za AMD mu Cinebench R20 yamitundu yambiri ndi 6%, ndipo mu ulusi umodzi ndi 14%.
Ryzen 9 9920X yatsopano idawonetsanso mwayi wokhutiritsa kuposa Core i9-3900X ku Blender.
Polankhula za machitidwe a Ryzen 7 3800X, AMD imayang'ana kwambiri pamasewera, ndipo ndizosangalatsa. Malinga ndi mayeso operekedwa omwe AMD idachita ndi khadi ya kanema ya GeForce RTX 2080, kuwongolera kwamitengo yamasewera odziwika bwino poyerekeza ndi akale apakati asanu ndi atatu a Ryzen 7 2700X kuyambira 11 mpaka 34%.
Zikuwoneka kuti izi zitha kulola tchipisi ta AMD kuchita komanso mapurosesa a Intel pansi pamasewera. Osachepera powonetsa Ryzen 7 3800X mu PlayerUnknown's Battlegrounds, purosesa iyi idawonetsa mitengo yofananira ndi Core i9-9900K.
M'njira, AMD idadzitamanso chifukwa chakuchita bwino kwa mapurosesa ake asanu ndi atatu ku Cinebench R20. M'mayesero amitundu yambiri, Ryzen 7 3800X inatha kupitirira Core i9-9900K ndi 2%, komanso muyeso wamtundu umodzi ndi 1%.
Ngati Ryzen 7 3700X ikufaniziridwa ndi Core i7-9700K, ndiye kuti mwayi pakuchita kwamitundu yambiri ndi 28%. Nthawi yomweyo, timakumbukira kuti kutentha kwanthawi zonse kwa Ryzen 7 3700X ndi 65 W, pomwe ma processor a Intel omwe amafananiza nawo ndi a 105-watt matenthedwe phukusi. Mtundu wachangu wa Ryzen 7 3800X wokhala ndi TDP wa 105 W ukuyembekezeka patsogolo pa Core i7-9700K kwambiri - ndi 37% pamayeso amitundu yambiri.
Pamapeto pake, kuyambitsidwa kwa tchipisi ta AMD kudapangitsa chitsitsimutso pakati pa okonda. Komabe, ndikofunikira kudziwa kuti zambiri sizikudziwikabe. Tsoka ilo, kampaniyo sinafotokoze komwe kulumpha kwakukulu kotereku kumachokera. Tikudziwa kuti Zen 2 imaphatikizanso kukonza zolosera zanthambi, kutsogoza malangizo, kukhathamiritsa kwa cache ya malangizo, kuchulukirachulukira komanso kutsika pang'ono pa basi ya Infinity Fabric, ndikusintha kwa kachesi ya data. Kuphatikiza apo, tsatanetsatane wokhudzana ndi kuthekera kwa overclocking sizikudziwika, zomwe palibe tsatanetsatane pano. Tikukhulupirira kuti zambiri zatsatanetsatane zidzamveka bwino pafupi ndi chilengezocho.
"Kuti mukhale mtsogoleri waukadaulo, muyenera kubetcha kwambiri," adatero Lisa Su, wamkulu wa AMD, m'mawu ake ofunikira a Computex 2019. Ndipo kubetcha komwe kampani yofiira idapanga lero idzakhala yopambana ndi Intel sichingachitike bwino.
