A yau a buɗe Computex 2019, AMD ta gabatar da na'urori na Ryzen na ƙarni na uku na 7nm da aka daɗe ana jira (Matisse). Jeri na sabbin samfura dangane da microarchitecture na Zen 2 ya haɗa da samfuran sarrafawa guda biyar, kama daga $ 200 da 5-core Ryzen 500 zuwa $ 9 Ryzen 7 kwakwalwan kwamfuta tare da cores goma sha biyu. Za a fara sayar da sabbin kayayyaki, kamar yadda aka zata a baya, a ranar 570 ga watan Yuli na wannan shekara. Tare da su, motherboards dangane da chipset XXNUMX kuma za su zo kasuwa.
Sakin na'urori na Ryzen 3000, dangane da Zen 2 microarchitecture, yayi kama da zai zama canjin tectonic da gaske a cikin kasuwar PC. Yin la'akari da bayanan da AMD ya gabatar a yau a wurin gabatarwa, kamfanin ya yi niyyar kama jagoranci kuma ya zama masana'antun masana'antun fasaha na fasaha don tsarin kasuwa. Wannan ya kamata a sauƙaƙe shi da sabuwar fasahar aiwatar da TSMC 7nm, wacce ake amfani da ita wajen kera Ryzen ƙarni na uku. Godiya ga shi, AMD ya sami damar magance manyan matsaloli guda biyu: da gaske rage yawan amfani da kwakwalwan kwamfuta masu inganci, da kuma sanya su cikin araha.
Sabuwar Zen 2 microarchitecture ya kamata kuma ya ba da gudummawa mai mahimmanci ga nasarar sabon Ryzen. Dangane da alkawuran AMD, haɓakar IPC (aiki a kowane agogo) idan aka kwatanta da Zen + ya kasance 15%, yayin da sabbin na'urori za su iya yin aiki a mafi girma mitoci. Hakanan daga cikin fa'idodin Zen 2 shine haɓakar ƙarar matakin cache na uku da haɓaka sau biyu a cikin aikin rukunin lamba na ainihi (FPU).
Tare da haɓaka microarchitecture, AMD kuma yana ba da sabon dandamali na X570, wanda yakamata ya ba da tallafi ga PCI Express 4.0, bas mai ninki biyu. Tsofaffin Socket AM4 uwayen uwa za su sami goyan baya ga sababbin na'urori ta hanyar sabunta BIOS, amma tallafi ga PCI Express 4.0 za a iyakance.
Koyaya, da alama babban makamin AMD a wannan matakin har yanzu zai kasance farashi. Kamfanin zai ci gaba da bin ka'idodin farashin farashi, wanda gaba ɗaya ya yi hannun riga da abin da Intel ya koya mana mu yi. Wataƙila tsarin 7-nm da amfani da chiplets sun ba AMD damar samun riba mai mahimmanci a cikin farashin samfur, saboda wanda gasa a cikin kasuwar sarrafawa za ta ƙaru da ƙarfi da ba a taɓa gani ba.
