Ngobusuku bokugqibela, uxwebhu lwezobugcisa lwavela kwi-Intanethi luchaza ezinye zeempawu zeprosesa ezilindelekileyo zeRyzen 4000 ezakhiwe kwi-microarchitecture yeZen 3. Ngokubanzi, ayizange izise naziphi na izityhilelo ezikhethekileyo, kodwa ziqinisekisile ezininzi zeengcamango ezenziwe ngaphambili. .
Ngokwamaxwebhu, i-Ryzen 4000 processors (i-codename Vermeer) iya kugcina ubume be-chiplet obuvezwe kubanduleli babo besizukulwana se-Zen 2. Abaqhubekeki bexesha elizayo, njengoko kwakunjalo ngaphambili, baya kuba ne-chiplet ye-I / O kunye ne-CCD enye okanye ezimbini. I-Core Complex Die) - ii-chiplets eziqulethe ii-computing cores.
Umahluko ophambili phakathi kweZen 3 izakuba lulwakhiwo lwangaphakathi lweCCD. Ngelixa okwangoku iCCX nganye inee-quad-core CCX (Core Complex), nganye inecache ye-3 MB L16 yecache, i-chiplets ye-Ryzen 4000 iya kuba ne-CCX engundoqo esibhozo. Umthamo we-L3 cache kwi-CCX nganye uya kunyuswa ukusuka kwi-16 ukuya kwi-32 MB, kodwa oku ngokucacileyo akuyi kukhokelela kutshintsho kwimemori ye-cache epheleleyo. Iiprosesa ze-Ryzen 4000 ezingundoqo ezisibhozo, eziya kuba ne-CCD chips enye, ziya kufumana i-32 MB L3 cache, kunye ne-16-core CPUs ezine-chiplets ezimbini zeCCD ziya kuba ne-64 MB L3 cache, eyenziwe ngamacandelo amabini.
Akukho mfuneko yokulindela utshintsho kumthamo we-cache ye-L2: i-core processor nganye iya kuba ne-512 KB ye-cache yenqanaba lesibini.
Nangona kunjalo, ukwandiswa kweCCX kuya kuba nefuthe elicacileyo ekusebenzeni. Nganye i-cores kwi-Zen 3 iya kuba nokufikelela ngokuthe ngqo kwinxalenye enkulu ye-L3 cache, kwaye ngaphezu koko, ii-cores ezininzi ziya kukwazi ukunxibelelana ngokuthe ngqo, ngokudlula i-Infinity Fabric. Oku kuthetha ukuba i-Zen XNUMX izakunciphisa umva wonxibelelwano phakathi kwe-core kunye nokunciphisa impembelelo yokusebenza komda olinganiselweyo webhasi yeprosesa ye-Infinity Fabric, into ethetha ukuba i-IPC (imiyalelo eyenziwe ngewotshi nganye) isalathisi siya kunyuka ekugqibeleni.
Ngexesha elifanayo, asithethi malunga naluphi na ukwanda kwenani lee-cores kwiiprosesa zabathengi. Inani eliphezulu leCCD chips kwi-Ryzen 4000 liya kulinganiselwa kwi-16, ngoko ke inani eliphezulu lee-cores kwiprosesa aliyi kukwazi ukudlula i-XNUMX.
Kwakhona, akukho tshintsho lusisiseko olulindelekileyo ngenkxaso yememori. Ngokulandelayo kuxwebhu, eyona ndlela iphezulu exhaswa ngokusemthethweni ye-Ryzen 4000 iya kuhlala i-DDR4-3200.
Uxwebhu alunikezeli naziphi na iinkcukacha malunga nokubunjwa koluhlu lwemodeli kunye nee-frequencies zeprosesa ezibandakanyiweyo kulo. Ulwazi oluthe vetshe ngokucacileyo luya kwaziwa nge-8 ka-Okthobha, xa i-AMD iza kubamba umsitho okhethekileyo onikezelwe kwiiprosesa zeRyzen 4000 kunye neZen 3 microarchitecture.
