AMD Zen 7 Grimlock: inodonha, cores uye V-Cache

Kugadziridzwa kwekupedzisira: 12/11/2025
Munyori: Alberto Navarro

  • CCD ine macores anosvika gumi nematanhatu, L2 cache ye2 MB per core uye L3 cache ye64 MB paCCD, ine V-Cache ye160 MB.
  • Desktop Ryzen processors anosvika makumi matatu nemaviri cores uye anosvika 448MB yeakasanganiswa L3 cache mune X3D akasiyana.
  • Grimlock Point uye Halo: musanganiswa weZen 7/Zen 7c cores uye kuita-per-watt kuvandudzwa kunosvika 36% pa3W.
  • TSMC A14 senzvimbo inotarirwa uye hwindo rinofungidzirwa rakananga 2027-2028, ine zvinogoneka AM5 kuenderana.

Ikozvino kuvuza kunongedza AMD Zen 7 (Grimlock) sekambani inotevera nhanho huru mukati high-performance CPUYakawanda yedata inobva Mutemo waMoore Wakafa Uye, kunyangwe iwo achienderana neazvino AMD mafambiro, Zvakanakisisa kuvabata nekuchenjerera kusvikira pane chisimbiso chepamutemo..

Pakati peakakosha maficha anodzokororwa mune akati wandei masosi kuwedzera kwemacores per chipset, iyo Kaviri iyo L2 cache pamusimboti uye kudzoka kwe3D V-Cache nekugona kukuru. Kune avo vanogadziridza muSpain kana Europe, iyo zvinokwanisika kuenderera kwe AM5 Zvingave zvekugutsurira kusimudzira pasina kuchinja mamaboard.

Ko kuvuza kwacho kunoratidzei nezveZen 7 (Grimlock)?

AMD Zen 7 Grimlock

Mwoyo werunyerekupe wakajeka: Imwe neimwe Zen 7 CCD yaizobatanidza kusvika kugumi nematanhatu, yakapetwa kaviri yemamwe magadzirirwo apfuura, ne 2 MB yeL2 cache pa core y 64MB L3 per chipset. Iyi nzira inosimbisa yemukati bandwidth uye data padyo, mbiru dze AMD's cache zano.

Pamakomputa edesktop, maCCD maviri aizobvumira processors ye kusvika kumacores makumi matatu nemaviri. The akasiyana X3D inogona kuwedzera kusvika ku160 MB 3D V-Cache mosaic paCCDkusimudza iyo inoshanda L3 pachiplet kune 224 MB uye, mune maviri eCCD zvigadziriso, kusvika 448 MB zvese.

Silverton uye Silverking chiplets: segmentation uye caching

Iyo Grimlock renji chirongwa chaizogadzirwa nacho maviri CPU chipslets: Silverton uye Silverking.

  • Silverton yaizove iyo yepamusoro-ye-iyo-yemhando modhi, ine 16 cores uye 32 MB yeL2 cache. (2 MB per core), 64 MB yeL3 cache uye rutsigiro rwe 160 MB V-Cache by chipset
  • Silverking yaizosarudza 8 cores, 16 MB yeL2 cache uye 32 MB yeL3 cache, isina 3D V-Cache..

Kubatanidza injini mbiri dzeSilverton dzaizovhura musuwo wepamusoro-we-iyo-mutsara zvigadziriso ne Makori gumi nematanhatu uye tambo makumi matatu nemavirikupeta zvakapetwa L2 kusvika 64 MB uye kuseta bhawa yeL3 cachet pazviverengero kusvika nguva pfupi yadarika zvaiita seyakasarudzika kune iyo nyanzvi chikamu.

Zvinofungidzirwa goho uye CPI

Nhamba dzekutanga dzinoratidza kuwedzera kwe CPI inenge 8% nekuda kwekugadzirisa cache, ne kuwedzera kuvandudzwa kwe16-20% mumabasa asiri ekutamba uye akakosha multithreaded scaling. Mune MT mamiriro, akati wandei masosi anoratidza kusvika pa67% zvichienzaniswa neZen 6inotsigirwa nemamwe maCCD cores, zvirinani cache manejimendi uye density.

Hazvisi zvese nezvekushambadzira: iyo yekusimbisa iri pane latency, bandwidth, uye peak kubata. Mumashoko anoshanda, izvi zvinogona kududzira ku nguva dzakagadzikana dzekupindura mukugadzira zvemukati, kubatanidza, simulation, uye analytics.

Handhelds uye inotakurika consoles: Grimlock Point uye Halo

Mukufamba, maAPU Grimlock Point y Grimlock Halo zvaizosanganisa nuclei Zen 7 uye Zen 7c (uye "Low-Power" block), kudzokorora fomula yezvizvarwa zvichangoburwa. Magadzirirwo ari kutariswa 4 Zen 7 + 8 Zen 7c (Point) uye 8 Zen 7 + 12 Zen 7c (Haro).

Kubudirira kwaizove kwakakosha: kuvandudzwa mukati mashandiro pa watt kusvika a 36% pa3 W, 32% pa7 W, 25% pa12 W y 17% pa22 WIzvi zvaizokanganisa zvakananga ultralight michina uye handheld, ne madonhwe mashoma efuremu uye mamwe akasununguka ekupisa profiles.

Kugadzira uye kuronga

KuCCDs, Zen 7 yaizonanga node TSMC A14, shanduko yepamusoro inotsiva yekare "2 nm" nomenclature. Iyo indasitiri inokwana inoratidza kumhara iyo, zvichienderana nechigadzirwa, Inogona kubva pakupera kwa2027 yenhare kusvika 2028 yedesktop uye data data.

Iyi nhanho inoenderana neiyo biennial kuburitsa cadence uye kukura kweanocheka-kumucheto node, chimwe chinhu chinoonekwa zvakare mu mutengo wekugadzira uye mu kuoma kwekubatanidza ndangariro yakawanda pedyo nekombuta.

AI chikuva, ISA, uye maficha

Manyuko akati kuti anonongedzera kuchinobvira AM5 kuenderanaIyi sarudzo, kana yakasimbiswa, yaizofambisa kugamuchirwa muEuropean retail channel. Padanho rekuraira, a itsva ISA set nerutsigiro rwe quantization uye kuvandudzwa mugadziriro yedata yeanomhanyisa.

Uyezve, AMD yatove yakataurwa zviri pamutemo Zen 7 mugwara rayo, kutarisira a matrix mota uye yakakura AI data mafomati akabatanidzwa mumacores. Iyo nzira inodarika AVX-512: chinangwa ndechekumhanyisa inference uye pre / post-kugadzirisa mukati me Generalist CPU.

Masevha uye nyanzvi kuyera

Mumunda weEPYC, chivakwa cheGrimlock chaizotsvaga kuwedzera mumacores uye cache kuchengetedza huzivi hwechipletConsistent latency uye yakafara L3 kuwana kwaizoiswa pamberi, zvinhu zvakakosha zvekuongorora uye dhatabhesi mabasa. European data centers.

Kunyange zvazvo nhamba chaidzo dzichichinja zvichienderana nekusefa, gwara rakajeka: more density per CCD, Yakakura V-Cache uye yakanatswa nzira dzemukati kutsigira yakanyanya data traffic.

Kana zvirongwa zvichienderana, Zen 7 ichasvika ichibatanidza AMD's "cache-yekutanga" modhi: 16-core CCD, Yakadhindwa L2, V-Cache pane steroids, uye yakajeka kuwedzera muAI uye kushanda nesimbaKune vashandisi muSpain neEurope, iyo yekufungidzira AM5 kuenderera mberi Uye kutarisa kwekuita kwewatt imwe neimwe kunoisa Grimlock pa radar yekusimudzira zvine musoro, pasina fanfare, asi nehukuru hwehunyanzvi hwaro.
