Jim Keller: Intel lub microarchitectures yav tom ntej yuav muab kev ua tau zoo tseem ceeb

Raws li hauv qab no los ntawm cov ntaub ntawv uas Jim Keller, tus lwm thawj coj ntawm thev naus laus zis thiab kev tsim qauv ntawm Intel, tau hais rau lub ntiaj teb, nws lub tuam txhab tam sim no tab tom ua haujlwm los tsim ib qho tshiab microarchitecture, uas yuav tsum dhau los ua "qhov tseem ceeb loj dua thiab ze rau qhov kev vam meej ntawm kev ua tau zoo. ntawm tus naj npawb ntawm transistors, "tshaj li kev tsim niaj hnub ntawm Sunny Cove. Thaj, qhov no yuav tsum tau txhais nyob rau hauv xws li ib txoj kev uas nyob rau hauv ob peb lub xyoos peb yuav tau txais ib tug processor uas yuav ua tau ntau complex thiab ho haib tshaj CPUs uas lub microprocessor loj tam sim no muaj.

Qhov tshiab Sunny Cove microarchitecture, uas Intel siv nyob rau hauv lub tshiab Ice Lake tiam processors, tau dhau los ua ib tug loj heev breakthrough, txij li thaum tom qab ib tug ntev so nws tau pom tau hais tias tau nce IPC (tus naj npawb ntawm cov lus qhia ua ib lub voj voog moos). Tab sis processor guru Jim Keller, uas tam sim no ua hauj lwm rau Intel, hais tias qhov no yog deb ntawm qhov kawg point. Tam sim no nws tab tom ua haujlwm rau tiam tom ntej ntawm microarchitecture, uas yuav muaj peev xwm siv tau tag nrho cov kev nce ntau hauv cov nyiaj siv hluav taws xob transistor xav tau nyob rau ob peb xyoos tom ntej no.

Raws li Intel kwv yees, qhov zoo ntawm Sunny Cove cores piv rau Coffee Lake cores hauv kev ua tau zoo nce mus txog 15-18% (ntawm tib lub moos ceev). Txawm li cas los xij, cov peev nyiaj transistor ntawm Sunny Cove tshaj cov peev nyiaj ntawm nws cov thawj coj los ntawm qhov tseem ceeb dua - nyob ib ncig ntawm 38%. Raws li cov ntaub ntawv tshaj tawm los ntawm Keller, cov tub ntxhais kawm nrog Sunny Cove microarchitecture muaj kwv yees li 300 lab 10-nm transistors, thaum lub Coffee Lake core suav nrog kwv yees li 217 lab 14-nm transistors. Nws hloov tawm tias qhov kev loj hlob ntawm cov khoom lag luam hauv Sunny Cove tsis ncav cuag qhov kev vam meej ntawm qhov loj ntawm cov nyiaj siv hluav taws xob transistor: qhov kev nce qib hauv kev tsim khoom tau ua rau kwv yees li ib nrab ntawm qhov nrawm raws li qhov nce hauv qhov nyuaj ntawm cov khoom siv hluav taws xob semiconductor. Raws li Keller, nws yuav tsum tsis txhob ua li no.

Muab kev qhuab qhia ntawm University of Berkeley, tus kws tshaj lij ntawm Intel tau tsa qhov teeb meem ntawm kev hloov pauv ntawm microarchitectures ntawm Intel processors thiab hauv zaj dab neeg tsis nyob ntawm Sunny Cove, tab sis tau hais txog qhov ua tau zoo rau qhov microarchitecture: "Sunny Cove ua haujlwm nrog. 800 cov lus qhia ib txhij, ua tiav los ntawm 3 txog 6 x86- cov lus qhia ib lub moos... Nws muaj cov ntaub ntawv loj heev, cov kws ua haujlwm loj heev. Tab sis peb tab tom ua hauj lwm ntawm ib tiam microarchitecture uas loj dua, thiab txoj cai ntawm kev loj hlob ntawm kev ua tau zoo yog ze rau linear. Nws yog qhov kev hloov pauv loj heev hauv kev xav. "

Lub hnub qub engineer txoj hauj lwm yog tias processor technology tseem nyob deb ntawm kev mus txog ib qho kev txwv. Raws li Keller, Intel muaj lub hom phiaj xav tau rau yav tom ntej, uas suav nrog kev nce 50 npaug ntawm cov transistors hauv cov txheej txheem thiab kev txhim kho loj hauv yuav luag txhua chav ua haujlwm. Thiab tsis muaj dab tsi ua tsis tau txog qhov no. Raws li Keller piav hais tias: β€œLub computer yog tsim los ntawm cov neeg coob coob, tab sis qhov tseeb lawv yog pawg me me. Koj tuaj yeem txhim kho ceg kwv yees, cov txheej txheem qhia, kev tsim qauv, ua kom zoo dua qub, siv cov cuab yeej tsim qauv zoo dua thiab cov tsev qiv ntawv zoo dua. Tus naj npawb ntawm cov ntawv thov sib txawv uas muaj chaw rau kev tsim kho tshiab yog qhov tseeb heev, loj heev. "

Intel cov phiaj xwm pej xeem tam sim no suav nrog ob qhov kev hloov pauv ntawm microarchitecture txhim kho dhau Sunny Cove. Tus tsim Willow Cove tom ntej no tau cog lus tias yuav hloov pauv mus rau cache subsystem thiab txav mus rau cov tshuab semiconductor tshiab (zoo li 7nm). Golden Cove tom qab ntawd yuav ua rau kom muaj kev ua tau zoo ib leeg thiab tsom mus rau AI ua haujlwm, nrog rau kev ua kom zoo dua qub uas xav tau rau kev ua tau zoo ntawm XNUMXG tes hauj lwm. Tej zaum Jim Keller muaj Golden Cove hauv siab hauv nws daim ntawv tshaj tawm, txawm hais tias tsis muaj dab tsi tau hais tshwj xeeb txog qhov no.
