AMD qhov kev nthuav qhia ntawm CES 2020 muaj cov ntsiab lus nthuav dav txog cov khoom tshiab ntawm lub tuam txhab thiab nws cov neeg koom nrog ze tshaj li cov xov xwm tshaj tawm tau tshaj tawm tom qab qhov xwm txheej. Cov neeg sawv cev ntawm lub tuam txhab tau hais txog kev sib koom ua ke uas tau ua tiav los ntawm kev siv AMD cov duab thiab cov txheej txheem hauv nruab nrab hauv ib qho system. SmartShift thev naus laus zis tso cai rau koj kom nce kev ua haujlwm nce mus txog 12% tsuas yog los ntawm kev tswj hwm cov zaus ntawm lub hauv paus thiab cov duab kos duab kom pom kev zoo dua ntawm cov khoom siv hauv computer.
Lub tswv yim ntawm optimizing kev siv cov cuab yeej kho vajtse tau ntev haunted developers ntawm mobile Cheebtsam. NVIDIA, piv txwv li, nyob rau hauv lub moj khaum ntawm technology tso cai rau koj hloov "ntawm ya" los ntawm cov duab tsis sib xws mus rau cov duab sib xyaw kom ua kom zoo zog siv hluav taws xob, nyob ntawm seb hom kev suav load. AMD tau mus ntxiv lawm: raws li ib feem ntawm SmartShift thev naus laus zis tau nthuav tawm ntawm CES 2020, nws tawm tswv yim kom hloov pauv cov zaus ntawm lub hauv paus processor thiab cov duab sib cais los xyuas kom muaj kev sib npaug ntawm kev ua tau zoo thiab kev siv lub zog.
Thawj lub khoos phis tawj los txhawb SmartShift yuav yog Dell G5 SE, uas yuav ua ke lub xov tooj ntawm tes hybrid 7nm Ryzen 4000 series processor thiab discrete Radeon RX 5600M cov duab, uas yog ib qho ntawm cov xwm txheej tseem ceeb rau SmartShift thev naus laus zis. Lub laptop yuav ntaus lub khw hauv lub quarter thib ob pib ntawm $ 799.
Hauv kev ua si, kev siv SmartShift thev naus laus zis yuav nce kev ua tau zoo txog li 10%; hauv cov ntawv thov xws li Cinebench R20, qhov nce tuaj yeem ncav cuag 12%. Cov thev naus laus zis yuav siv rau hauv ob qho tib si mobile thiab desktop. Qhov tseem ceeb tshaj plaws yog tias AMD central processor nyob rau hauv lawv yog nyob ib sab ntawm ib daim video discrete raws li Radeon graphics processor. Ntawm lwm yam, hauv xov tooj ntawm tes SmartShift yuav ua rau kom lub roj teeb lub neej tsis tas yuav rov them dua.
Me me nti ntawm 7nm processors Renoir tseem nyob monolithic
Ntawm CES 2020, AMD CEO Lisa Su qauv ntawm 7nm Renoir hybrid processor. Raws li cov ntaub ntawv ua ntej, lub monolithic siv lead ua muaj thaj tsam ntawm tsis pub ntau tshaj 150 mm2, thiab qhov kev npaj no txawv ntawm nws cov duab thiab cov servers. Los ntawm txoj kev, Renoir processors kuj tsis muab kev txhawb nqa rau PCI Express 4.0, txwv lawv tus kheej rau PCI Express 3.0. Radeon graphics subsystem (tsis tau qhia txog tiam) nyob rau hauv lub siab tshaj plaws configuration muaj yim execution units, thiab lub thib peb cache yog txwv rau 8 megabytes. Nws paub meej tias vim li cas AMD yuav tsum "txuag silicon." Txawm li cas los xij, qhov no tsis cuam tshuam rau lub khoos phis tawj cores - tuaj yeem muaj txog li yim ntawm lawv ntawm cov chips zoo li no.
Lisa Su tau piav qhia tias rau qhov nce ntxiv ntawm ob npaug ntawm kev siv zog ntawm Renoir processors piv rau 12-nm cov thawj coj, ib qho yuav tsum ua tsaug rau 7-nm thev naus laus zis - nws yog qhov tseem ceeb uas tau txiav txim siab qhov zoo tshaj plaws ntawm 70%, thiab tsuas yog 30% cuam tshuam nrog kev tsim vaj tsev thiab layout hloov. Thawj lub laptops raws li Renoir yuav tshwm sim hauv peb lub hlis twg tam sim no; los ntawm qhov kawg ntawm lub xyoo no, ntau tshaj li ib puas qauv ntawm lub laptops raws li cov txheej txheem no yuav raug tso tawm.
Raws li Lisa Su ntxiv, AMD npaj siab yuav tsim thiab tso tawm ntau dua nees nkaum 7nm cov khoom lag luam xyoo no thiab xyoo dhau los. Cov no suav nrog cov khoom lag luam thib ob 7nm, tab sis AMD cov neeg sawv cev tau piav qhia rau AnandTech editor Ian Cuttress tias Renoir APUs tau nthuav tawm lub lim tiam no yog tsim los siv tib yam thawj tiam 7nm thev naus laus zis li Matisse lossis Rome. AMD cov khoom siv hu ua EUV lithography yuav pib tsim los ntawm TSMC tom qab me ntsis - raws li cov ntaub ntawv tsis raug cai, ze rau lub quarter thib peb ntawm lub xyoo no.
