Izolo ebusuku, kuvele ku-inthanethi idokhumenti yobuchwepheshe echaza ezinye zezici ze-Ryzen 4000 processors ezilindelekile ezakhelwe phezu kwe-microarchitecture ye-Zen 3. Ngokuvamile, ayizange ilethe noma yiziphi izambulo ezikhethekile, kodwa iqinisekise okuningi kokucatshangelwa okwenziwe ngaphambili. .
Ngokusho kwemibhalo, ama-processor we-Ryzen 4000 (i-codename Vermeer) azogcina ukuhlelwa kwe-chiplet okwethulwe kwabandulela isizukulwane se-Zen 2. Amaphrosesa amaningi wesikhathi esizayo, njengoba kwakunjalo ngaphambili, azoba ne-chiplet ye-I/O kanye ne-CCD eyodwa noma amabili. I-Core Complex Die) - ama-chiplets aqukethe ama-computing cores.
Umehluko obalulekile phakathi kwamaphrosesa weZen 3 kuzoba yisakhiwo sangaphakathi seCCD. Nakuba okwamanje i-CCD ngayinye iqukethe ama-quad-core CCX (Core Complex), ngayinye enengxenye yayo yenqolobane engu-3 MB L16, ama-chiplets e-Ryzen 4000 azoqukatha i-CCX eyodwa eyisishiyagalombili. Ivolumu yenqolobane ye-L3 ku-CCX ngayinye izokwenyuswa isuka ku-16 iye ku-32 MB, kodwa lokhu ngokusobala ngeke kuholele ekushintsheni komthamo wenkumbulo yenqolobane isiyonke. Amaphrosesa angu-4000 we-Ryzen 32 series processors, manje azoba ne-CCD chips eyodwa, azothola inqolobane engu-3 MB L16, futhi ama-CPU angu-64-core anama-chiplet amabili e-CCD azoba ne-cache engu-3 MB LXNUMX, eyakhiwe izingxenye ezimbili.
Asikho isidingo sokulindela izinguquko kuvolumu yenqolobane ye-L2: umongo wephrosesa ngamunye uzoba no-512 KB wenqolobane yezinga lesibili.
Nokho, ukukhulisa i-CCX kuzoba nomthelela osobala ekusebenzeni. I-cores ngayinye ku-Zen 3 izoba nokufinyelela okuqondile engxenyeni enkulu yenqolobane ye-L3, futhi ngaphezu kwalokho, ama-cores amaningi azokwazi ukuxhumana ngokuqondile, adlule i-Infinity Fabric. Lokhu kusho ukuthi i-Zen XNUMX izonciphisa ukubambezeleka kokuxhumana phakathi kwama-core futhi inciphise umthelela wokusebenza komkhawulokudonsa okhawulelwe webhasi lomprosesa le-Infinity Fabric, okusho ukuthi inkomba ye-IPC (imiyalo ekhishiwe ngewashi ngalinye) izokwanda ekugcineni.
Ngesikhathi esifanayo, asikhulumi nganoma yikuphi ukwanda kwenani lama-cores kuma-processors abathengi. Inombolo enkulu yama-chiplets e-CCD ku-Ryzen 4000 izokhawulelwa kokubili, ngakho-ke inani eliphezulu lama-cores kuphrosesa ngeke likwazi ukudlula u-16.
Futhi, azikho izinguquko ezibalulekile ezilindelekile ngokusekelwa kwenkumbulo. Ngokulandelayo kudokhumenti, imodi ephezulu esekelwe ngokusemthethweni ye-Ryzen 4000 izohlala i-DDR4-3200.
Amadokhumenti awanikezi noma yimiphi imininingwane mayelana nokwakheka kwebanga lemodeli kanye namaza okucubungula afakwe kuwo. Ulwazi oluningiliziwe ngokusobala luzokwaziwa ngo-Okthoba 8, lapho i-AMD izoba nomcimbi okhethekile onikezelwe kuma-Ryzen 4000 processors kanye ne-Zen 3 microarchitecture.
