I-AMD CTO incokola neChiplet: Ixesha lokutywinwa ngokubambisana kweefoto zombane liyeza

Abaphathi benkampani ye-chip ye-AMD bathi iiprosesa ze-AMD zexesha elizayo zinokuxhotyiswa ngee-accelerator ezithe ngqo kwisizinda, kwaye ezinye ii-accelerators zenziwe ngabantu besithathu.

USekela Mongameli oPhezulu uSam Naffziger uthethe neGosa eliPhezulu leTekhnoloji ye-AMD uMark Papermaster kwividiyo ekhutshwe ngoLwesithathu, egxininisa ukubaluleka komgangatho we-chip encinci.

“Ii-accelerators ezithe ngqo kwi-Domain, yeyona ndlela ilungileyo yokufumana eyona ntsebenzo intle ngedola nganye ngewatt.Ngoko ke, kuyimfuneko ngokupheleleyo kwinkqubela phambili.Awunakukwazi ukwenza iimveliso ezithile kwindawo nganye, ke into esinokuyenza kukuba ne-ecosystem encinci ye-chip - ngokusisiseko ithala leencwadi, "ucacisile uNaffziger.

Wayebhekisela kwi-Universal Chiplet Interconnect Express (UCIe), umgangatho ovulekileyo wonxibelelwano lwe-Chiplet oluye lwahlala ukususela ekudalweni kwayo ekuqaleni kwe-2022. Iphumelele inkxaso ebanzi evela kubadlali abakhulu bezoshishino ezifana ne-AMD, i-Arm, i-Intel kunye ne-Nvidia, ngokunjalo. njengamanye amaninzi amancinci.

Ukusukela ekusungulweni kwesizukulwana sokuqala se-Ryzen kunye ne-Epyc processors ngo-2017, i-AMD ibiphambili kwi-architecture encinci ye-chip.Ukusukela ngoko, ithala leencwadi leNdlu yeZen yeetshiphusi ezincinci likhule laquka i-computing ezininzi, i-I/O, kunye neetshiphusi zegraphics, ezidibanisa kwaye zizifake kubathengi kunye neziko ledatha.

Umzekelo wale ndlela unokufumaneka kwi-AMD ye-Instinct MI300A APU, eyasungulwa ngoDisemba ka-2023, Ipakishwe ngeetshiphusi ezincinci ezili-13 (iitshiphusi ezine ze-I/O, iitshiphusi ze-GPU ezintandathu, kunye neetshiphusi ezintathu ze-CPU) kunye neememori ze-HBM3 ezisibhozo.

UNaffziger uthe kwixesha elizayo, imigangatho efana ne-UCIe inokuvumela iitshiphusi ezincinci ezakhiwe ngabantu besithathu ukuba zifumane indlela yazo kwiiphakheji ze-AMD.Ukhankanye i-silicon photonic interconnect - itekhnoloji enokunciphisa iibhotile zebhanwidth - njengokuba inokubanakho ukuzisa iitshiphusi ezincinci zomntu wesithathu kwiimveliso ze-AMD.

I-Naffziger ikholelwa ukuba ngaphandle koqhagamshelwano lwetshiphu yamandla aphantsi, itekhnoloji ayinakwenzeka.

"Isizathu sokuba ukhethe ukuqhagamshelwa kwe-optical kuba ufuna i-bandwidth enkulu," uyachaza.Ke ufuna amandla aphantsi kancinci ukufezekisa oko, kwaye i-chip encinci kwiphakheji yindlela yokufumana olona jongano lwamandla lusezantsi. ”Wongeze ukuba ucinga ukuba utshintsho kwi-optics yokupakisha "luyeza."

Ukuza kuthi ga ngoku, uqalo oluninzi lwe-silicon photonics sele luphehlelela iimveliso ezinokwenza kanye loo nto.I-Ayar Labs, umzekelo, iphuhlise i-UCIe ye-photonic chip ehambelanayo edityaniswe kwiprototype ye-graphics analytics analytics accelerator Intel eyakhelwe kulo nyaka uphelileyo.

Nokuba iitshiphusi ezincinci zomntu wesithathu (iifotonics okanye obunye ubuchwephesha) ziya kufumana indlela yazo kwiimveliso ze-AMD kusaza kubonakala.Njengoko besesitshilo ngaphambili, ukubekwa emgangathweni ngomnye wemicelimngeni emininzi ekufuneka yoyiswe ukuvumela iitshiphusi ezininzi ze-chip.Sicele i-AMD ngolwazi oluthe kratya malunga neqhinga labo letshiphu encinci kwaye siya kukwazisa ukuba sifumana nayiphi na impendulo.

I-AMD sele ibonelele ngeetshiphusi zayo ezincinci kubavelisi beetshiphu abakhuphisana nabo.Icandelo le-Intel's Kaby Lake-G, elaziswa ngo-2017, lisebenzisa i-Chipzilla's 8th-generation core kunye ne-AMD's RX Vega Gpus.Inxalenye kutshanje iphinde yavela kwibhodi ye-NAS ye-Topton.
