AMD CTO tham txog Chiplet: Lub sijhawm ntawm photoelectric co-sealing tab tom los

AMD chip tuam txhab cov thawj coj tau hais tias yav tom ntej AMD processors yuav tau nruab nrog cov npe tshwj xeeb accelerators, thiab txawm tias qee qhov accelerators yog tsim los ntawm peb tog.

Tus Lwm Thawj Coj Thawj Coj Sam Naffziger tau tham nrog AMD Tus Thawj Saib Xyuas Technology Mark Papermaster hauv cov yeeb yaj kiab tshaj tawm hnub Wednesday, hais txog qhov tseem ceeb ntawm kev tsim cov txheej txheem me me.

"Domain-specific accelerators, uas yog txoj hauv kev zoo tshaj plaws kom tau txais qhov kev ua tau zoo tshaj plaws rau ib duas las ib watt.Yog li ntawd, nws yog qhov tsim nyog rau kev nce qib.Koj tsis tuaj yeem them taus los tsim cov khoom tshwj xeeb rau txhua qhov chaw, yog li peb tuaj yeem ua tau yog muaj lub tshuab me me - qhov tseem ceeb yog lub tsev qiv ntawv, "Naffziger piav qhia.

Nws tau hais txog Universal Chiplet Interconnect Express (UCIe), tus qauv qhib rau Chiplet kev sib txuas lus uas tau nyob ib puag ncig txij li nws tsim thaum ntxov 2022. Nws tau txais kev txhawb nqa dav dav los ntawm kev lag luam loj xws li AMD, Arm, Intel thiab Nvidia, thiab. raws li ntau lwm hom me me.

Txij li thaum pib thawj tiam ntawm Ryzen thiab Epyc processors nyob rau hauv 2017, AMD tau nyob rau hauv pem hauv ntej ntawm me me nti architecture.Txij thaum ntawd los, Lub Tsev ntawm Zen lub tsev qiv ntawv ntawm cov chips me tau loj hlob los suav nrog ntau lub laij lej, I / O, thiab cov duab kos, sib txuas thiab encapsulating lawv hauv nws cov neeg siv khoom thiab cov ntaub ntawv chaw ua haujlwm.

Ib qho piv txwv ntawm txoj hauv kev no tuaj yeem pom hauv AMD's Instinct MI300A APU, uas tau tsim tawm thaum Lub Kaum Ob Hlis 2023, Ntim nrog 13 tus neeg me me (plaub I / O chips, rau GPU chips, thiab peb CPU chips) thiab yim HBM3 nco pawg.

Naffziger tau hais tias yav tom ntej, cov qauv zoo li UCIe tuaj yeem tso cai rau cov chips me uas tsim los ntawm cov neeg thib peb los nrhiav lawv txoj hauv kev rau hauv AMD pob.Nws hais txog silicon photonic interconnect - ib lub tshuab uas tuaj yeem yooj yim bandwidth bottlenecks - raws li muaj peev xwm nqa cov chips me me thib peb rau AMD cov khoom.

Naffziger ntseeg hais tias tsis muaj kev sib txuas ntawm lub zog qis qis, cov thev naus laus zis tsis tuaj yeem ua tau.

"Vim li cas koj xaiv qhov kev sib txuas kho qhov muag yog vim koj xav tau bandwidth loj," nws piav qhia.Yog li koj xav tau lub zog qis ib me ntsis kom ua tiav qhov ntawd, thiab lub nti me me hauv ib pob yog txoj hauv kev kom tau txais lub zog qis tshaj plaws. "Nws hais ntxiv tias nws xav tias kev hloov pauv mus rau kev ntim khoom sib koom ua ke yog "los."

Txog qhov kawg, ntau lub silicon photonics startups twb pib cov khoom uas tuaj yeem ua tau li ntawd.Ayar Labs, piv txwv li, tau tsim UCIe tshaj photonic nti uas tau muab tso ua ke rau hauv cov qauv duab analytics accelerator Intel tsim xyoo tas los.

Txawm hais tias tus thib peb cov chips me me (photonics lossis lwm yam thev naus laus zis) yuav pom lawv txoj hauv kev rau AMD cov khoom tseem yuav pom.Raws li peb tau tshaj tawm ua ntej, kev tsim qauv tsuas yog ib qho ntawm ntau qhov kev sib tw uas yuav tsum tau kov yeej kom tso cai rau ntau lub chips sib txawv.Peb tau nug AMD kom paub ntau ntxiv txog lawv lub tswv yim me me thiab yuav qhia rau koj paub yog tias peb tau txais cov lus teb.

AMD yav dhau los tau muab nws cov chips me me rau cov neeg sib tw chipmakers.Intel's Kaby Lake-G tivthaiv, qhia hauv 2017, siv Chipzilla's 8th-tiam core nrog rau AMD's RX Vega Gpus.Ib feem tsis ntev los no rov tshwm sim ntawm Topton's NAS board.
