AMD CTO imalankhula Chiplet: Nthawi yosindikizanso ma photoelectric ikubwera

Oyang'anira kampani ya AMD chip adati ma processor amtsogolo a AMD atha kukhala ndi ma accelerators enieni, ndipo ngakhale ma accelerator ena amapangidwa ndi anthu ena.

Wachiwiri kwa Purezidenti Sam Naffziger adalankhula ndi Chief Technology Officer wa AMD Mark Papermaster muvidiyo yomwe idatulutsidwa Lachitatu, ndikugogomezera kufunikira kokhazikika kwa chip.

"Zothamanga zamtundu wamtundu, ndiye njira yabwino kwambiri yopezera ntchito yabwino pa dola pa watt iliyonse.Choncho, m'pofunika mwamtheradi kuti patsogolo.Simungakwanitse kupanga zinthu zenizeni zadera lililonse, ndiye zomwe tingachite ndikukhala ndi kachidutswa kakang'ono ka chip - makamaka laibulale, "Naffziger adalongosola.

Amanena za Universal Chiplet Interconnect Express (UCIe), muyezo wotseguka wa kulumikizana kwa Chiplet komwe kwakhalako kuyambira pomwe idakhazikitsidwa koyambirira kwa 2022. Yapezanso chithandizo chofala kuchokera kwa osewera akuluakulu amakampani monga AMD, Arm, Intel ndi Nvidia, komanso. monga ena ambiri ang'onoang'ono zopangidwa.

Chiyambireni m'badwo woyamba wa ma processor a Ryzen ndi Epyc mu 2017, AMD yakhala patsogolo pakupanga kachipangizo kakang'ono.Kuyambira pamenepo, laibulale ya House of Zen ya tchipisi tating'ono yakula ndikuphatikiza ma compute angapo, I/O, ndi tchipisi tazithunzi, kuphatikiza ndi kuziyika mu ogula ndi data center processors.

Chitsanzo cha njirayi chikupezeka mu AMD's Instinct MI300A APU, yomwe idakhazikitsidwa mu Disembala 2023, Yopakidwa ndi tchipisi tating'ono 13 (tchipisi zinayi za I/O, tchipisi 6 za GPU, ndi tchipisi ta CPU zitatu) ndi masanjidwe asanu ndi atatu a HBM3.

Naffziger adati m'tsogolomu, miyezo ngati UCIe ikhoza kulola tchipisi tating'ono tating'ono topangidwa ndi anthu ena kuti tipeze njira yolowera mumaphukusi a AMD.Ananenanso kuti silicon photonic interconnect - ukadaulo womwe ungachepetse kutsekeka kwa bandwidth - kukhala ndi kuthekera kobweretsa tchipisi tachitatu kuzinthu za AMD.

Naffziger amakhulupirira kuti popanda kulumikizidwa kwa chip chochepa mphamvu, ukadaulo sungatheke.

"Chifukwa chomwe mumasankhira kulumikizidwa kwa kuwala ndi chifukwa mukufuna bandwidth yayikulu," akufotokoza.Chifukwa chake mumafunika mphamvu zochepa pang'ono kuti mukwaniritse izi, ndipo kachipangizo kakang'ono ka phukusi ndi njira yopezera mphamvu yotsika kwambiri. ”Ananenanso kuti akuganiza kuti kusintha kwa makina ophatikizira "kukubwera."

Kuti izi zitheke, oyambitsa angapo a silicon photonics akuyambitsa kale zinthu zomwe zingachite zomwezo.Mwachitsanzo, Ayar Labs apanga UCIe yogwirizana ndi fotonic chip yomwe yaphatikizidwa mu prototype graphics analytics accelerator Intel yomangidwa chaka chatha.

Kaya tchipisi tating'onoting'ono (mafotonic kapena matekinoloje ena) apeza njira yolowera muzinthu za AMD sizikuwonekerabe.Monga tanenera kale, kuyimitsidwa ndi chimodzi mwazovuta zomwe ziyenera kuthetsedwa kuti tilole tchipisi tamitundu yambiri.Tafunsa AMD kuti mudziwe zambiri za njira yawo yaying'ono ya chip ndipo tikudziwitsani ngati titalandira yankho.

AMD idapereka kale tchipisi tating'onoting'ono kwa opanga ma chipmaker.Chigawo cha Intel's Kaby Lake-G, chomwe chinayambitsidwa mu 2017, chimagwiritsa ntchito Chipzilla's 8th-generation core pamodzi ndi AMD's RX Vega Gpus.Gawoli lidawonekeranso pa board ya Topton's NAS.
