Nag hmo, ib daim ntawv qhia kev tshaj tawm hauv Is Taws Nem piav qhia qee tus yam ntxwv ntawm qhov xav tau Ryzen 4000 processors ua rau Zen 3 microarchitecture. ua ntej.
Raws li cov ntaub ntawv, Ryzen 4000 processors (codename Vermeer) yuav khaws cov chiplet layout qhia nyob rau hauv lawv predecessors ntawm lub Zen 2 tiam. Yav tom ntej pawg processors, raws li yav tas los cov ntaub ntawv, yuav muaj ib tug I / O chiplet thiab ib los yog ob CCDs ( Core Complex Die) - chiplets uas muaj cov cores.
Qhov sib txawv tseem ceeb ntawm Zen 3 processors yuav yog cov qauv sab hauv ntawm CCD. Thaum tam sim no txhua CCD muaj ob quad-core CCX (Core Complex), txhua tus muaj nws tus kheej 3 MB L16 cache ntu, Ryzen 4000 chiplets yuav muaj ib yim-core CCX. Qhov ntim ntawm L3 cache hauv txhua CCX yuav nce los ntawm 16 txog 32 MB, tab sis qhov no pom tseeb yuav tsis ua rau muaj kev hloov pauv ntawm tag nrho cov cache nco muaj peev xwm. Yim-core Ryzen 4000 series processors, uas tam sim no yuav muaj ib qho CCD chiplet, yuav tau txais 32 MB L3 cache, thiab 16-core CPUs nrog ob lub CCD chiplets yuav muaj 64 MB L3 cache, muaj li ntawm ob ntu.
Tsis tas yuav cia siab tias yuav hloov pauv ntawm qhov ntim ntawm L2 cache: txhua tus tub ntxhais processor yuav muaj 512 KB ntawm qib thib ob cache.
Txawm li cas los xij, qhov loj ntawm CCX yuav muaj qhov cuam tshuam rau kev ua tau zoo. Txhua lub cores hauv Zen 3 yuav muaj kev nkag ncaj qha mus rau ib feem loj ntawm L3 cache, thiab ntxiv rau, ntau cov cores yuav tuaj yeem sib txuas lus ncaj qha, hla ntawm Infinity Fabric. Qhov no txhais tau hais tias Zen XNUMX yuav txo qis kev sib txuas lus latency thiab txo qhov kev ua tau zoo ntawm qhov txwv bandwidth ntawm tus processor's Infinity Fabric bus, uas txhais tau hais tias IPC (cov lus qhia ua tiav ib lub moos) qhov taw qhia thaum kawg yuav nce.
Nyob rau tib lub sijhawm, peb tsis tau tham txog ib qho kev nce ntawm cov cores hauv cov neeg siv khoom siv. Qhov siab tshaj plaws ntawm CCD chiplets nyob rau hauv Ryzen 4000 yuav raug txwv rau ob, yog li qhov siab tshaj plaws ntawm cov cores hauv processor yuav tsis tuaj yeem tshaj 16.
Tsis tas li ntawd, yuav tsis muaj qhov hloov pauv tseem ceeb nrog kev txhawb nqa nco. Raws li hauv qab no los ntawm cov ntaub ntawv, qhov siab tshaj plaws kev txhawb nqa hom rau Ryzen 4000 yuav nyob twj ywm DDR4-3200.
Cov ntaub ntawv tsis muab cov ntsiab lus hais txog qhov muaj pes tsawg leeg ntawm cov qauv ntau thiab cov zaus ntawm cov processors suav nrog hauv nws. Cov ntaub ntawv ntxaws ntxiv yuav pom meej paub thaum Lub Kaum Hli 8, thaum AMD yuav tuav ib qho kev tshwm sim tshwj xeeb rau Ryzen 4000 processors thiab Zen 3 microarchitecture.
