Thaum Google tshaj tawm nws tus kheej ambitions hauv kev ua si streaming thiab ... kev txhim kho ntawm Stadia cov kev pabcuam, ntau cov lus nug tau tshwm sim txog cov cuab yeej tshawb fawb loj yuav siv rau hauv nws cov huab platform tshiab. Qhov tseeb yog tias Google nws tus kheej tau muab cov lus piav qhia tsis meej heev ntawm kev teeb tsa kho vajtse, tshwj xeeb tshaj yog nws cov duab kos: qhov tseeb, nws tsuas yog tau cog lus tias cov tshuab tshaj tawm cov kev ua si rau cov neeg siv ntawm qhov kev pabcuam yuav raug sib sau ua ke ntawm qee qhov kev cai AMD graphics accelerators nrog HMB2 nco. , 56 lub tshuab xam zauv (CU) thiab kev ua haujlwm ntawm 10,7 teraflops. Raws li cov lus piav qhia no, ntau tus tau ua , uas peb tab tom tham txog 7-nm AMD Vega graphics processors, uas yog siv nyob rau hauv cov neeg siv khoom Radeon VII video phaib. Tab sis cov ntaub ntawv tshiab qhia tias Stadia yuav siv thawj tiam Vega GPUs zoo ib yam li Vega 56.
Txhawm rau lees tias peb tab tom tham txog thawj tiam Vega tau tso cai los ntawm cov ntaub ntawv uas tau tshwm sim hauv lub vev xaib ntawm Khronos, lub koom haum uas tsim thiab tsim Vulkan graphical interface. Raws li tau hais nyob rau ntawd, "Google Games Platform Gen 1", uas yog, kho vajtse platform hauv thawj tiam Stadia kev pabcuam, yuav ua tau zoo nrog Vulkan_1_1 ua tsaug rau kev siv AMD GCN 1.5 architecture (tsib tiam GCN). Thiab qhov no txhais tau hais tias GPUs siv nyob rau hauv cov ntaub ntawv no yog architecturally raws li thawj Vega video phaib raws li 14 nm chips, thaum tom qab Vega processors, tsim siv 7 nm txheej txheem thev naus laus zis thiab siv hauv Radeon VII video phaib, koom nrog kev txhim kho. architecture GCN 1.5.1 (Tsim 5.1).
Hauv lwm lo lus, nws zoo nkaus li tias AMD tab tom npaj rau Google tsis muaj dab tsi ntau tshaj li qhov tshwj xeeb ntawm Vega 56. Daim ntawv tshaj tawm Stadia tau hais tias cov duab nrawm rau cov kev pabcuam yuav tau txais 56 CUs, 10,7 teraflops kev ua tau zoo thiab HBM2 nco nrog bandwidth 484 GB / s. Tsis tas li ntawd, nws tau hais tias tag nrho cov cim xeeb ntawm lub system (RAM thiab video nco hauv tag nrho) yuav yog 16 GB. Qhov no tuaj yeem txhais raws li txoj hauv kev uas tus accelerator rau Stadia tsuas yog qhov tshwj xeeb ntawm Vega 56 nrog 8 GB HMB2 thiab nce cov tub ntxhais thiab video nco zaus.
Nws hloov tawm tias AMD tseem tsis tau twv kom muab Google siv 7-nm Vega chips. Thiab qhov no yog qhov yooj yim heev los piav qhia: cov kev daws teeb meem paub tab thiab lub sijhawm sim hauv cov ntsiab lus ntawm cov ntawv cog lus loj loj yog qhov kev daws teeb meem ntau dua. Tsis tas li ntawd, los ntawm kev muab 14nm paub tab ntawm Vega rau Stadia, AMD yuav muaj peev xwm rho tawm cov nyiaj tau los ntau dua nyob rau theem no thiab tiv thaiv nws tus kheej los ntawm cov teeb meem muaj peev xwm. Kev tsim khoom ntawm 14nm Vega chips yog tsim tau zoo thiab siv qhov chaw ntawm GlobalFoundries cov chaw, thaum kev txiav txim rau kev tsim cov 7nm chips yuav tsum tau muab tso rau TSMC, uas tuaj yeem tsim qee yam teeb meem nrog ob qho tib si qib tawm los ntawm cov khoom tsim nyog thiab cov khoom ntim.
Tib lub sijhawm, tsis muaj qhov tsis ntseeg tias Google Stadia platform yuav txhim kho, thiab GPUs tso tawm siv 7nm thev naus laus zis yuav pom tseeb tuaj rau nws sai lossis tom qab. Txawm li cas los xij, feem ntau cov no yuav tsis yog Vega chips lawm, tab sis kev nce qib ntxiv nrog Navi architecture, uas AMD npaj yuav pib pib lub quarter thib peb.
Google Stadia xav tias yuav tso tawm xyoo 2019 thiab yuav tso cai rau cov neeg siv khoom siv "kwj" kev ua si rau lawv cov khoom siv hauv 4K daws teeb meem nrog tus ncej tus nqi ntawm 60 Hz.
