Google payakazivisa zvishuvo zvayo mukutepfenyura kwemutambo uye... kuvandudzwa kweSevhisi yeStadia, mibvunzo yakawanda yamuka pamusoro pemidziyo iyo hofori yekutsvaga ichashandisa mupuratifomu yayo yegore. Chokwadi ndechekuti Google pachayo yakapa tsananguro isina kujeka yekugadziriswa kwehardware, kunyanya chikamu chayo chemifananidzo: kutaura zvazviri, zvakangovimbiswa kuti masisitimu ekutepfenyura mitambo kune vashandisi vesevhisi aizounganidzwa pane imwe tsika AMD graphics accelerators ine HMB2 memory. , 56 computing units (CU) uye kushanda kwe10,7 teraflops. Zvichienderana nerondedzero iyi, vazhinji vakaita , kuti tiri kutaura nezve 7-nm AMD Vega graphics processors, iyo inoshandiswa muvatengi Radeon VII makadhi evhidhiyo. Asi ruzivo rutsva runoratidza kuti Stadia ichashandisa chizvarwa chekutanga Vega GPUs yakafanana neVega 56.
Kuti titaure kuti tiri kutaura nezvechizvarwa chekutanga Vega inobvumirwa nedata rakaonekwa pawebhusaiti yeKhronos, sangano rinogadzira uye rinogadzira Vulkan graphical interface. Sezvinoratidzwa ipapo, "Google Games Platform Gen 1", kureva kuti, iyo hardware platform muchizvarwa chekutanga Stadia sevhisi, ichaenderana neVulkan_1_1 nekuda kwekushandiswa kwe AMD GCN 1.5 architecture (chizvarwa chechishanu GCN). Uye izvi zvinoreva kuti maGPU anoshandiswa mune iyi kesi anovakwa anowirirana nevekutanga Vega makadhi evhidhiyo akavakirwa pa14 nm machipisi, nepo akazotevera Vega processors, akagadzirwa achishandisa 7 nm process tekinoroji uye anoshandiswa muRadeon VII makadhi evhidhiyo, ndeeyakagadziridzwa. zvivakwa GCN 1.5.1 (Generation 5.1).
Mune mamwe mazwi, zvinoita sezvingangoita kuti AMD iri kugadzirira Google chimwe chinhu kunze kweshanduro yakakosha yeVega 56. Chiziviso cheStadia chakataura kuti magraphic accelerators ebasa achagamuchira 56 CUs, 10,7 teraflops performance uye HBM2 memory ine bandwidth 484 GB/ s. Uye zvakare, zvakanzi huwandu hwese hwese system memory (RAM uye vhidhiyo memory muhuwandu) ichave 16 GB. Izvi zvinogona kududzirwa nenzira yekuti accelerator yeStadia ingori yakasarudzika vhezheni yeVega 56 ine 8 GB HMB2 uye yakawedzera musimboti uye vhidhiyo ndangariro frequency.
Zvinoitika kuti AMD haisati yamboshinga kupa Google kushandisa 7-nm Vega machipi. Uye izvi zviri nyore kutsanangura: mhinduro dzakakura uye dzakaedzwa-nguva mumamiriro ezvinhu ezvibvumirano zvakakura zvekugovera ndiyo mhinduro yakavimbika. Pamusoro pezvo, nekupa yakakura 14nm vhezheni yeVega yeStadia, AMD ichakwanisa kutora mari yepamusoro panguva ino uye kuzvidzivirira kubva kumatambudziko angangoitika. Kugadzirwa kwe14nm Vega machipisi kwakanyatso kusimbiswa uye kunoitika kunzvimbo dzeGlobalFoundries, nepo maodha ekugadzirwa kwe7nm machipisi aifanirwa kuiswa neTSMC, izvo zvinogona kuunza mamwe matambudziko neese goho remachipisi akakodzera uye mavhoriyamu ekugadzira.
Panguva imwecheteyo, hapana mubvunzo kuti Google Stadia chikuva ichakura, uye maGPU akaburitswa achishandisa 7nm tekinoroji achauya kwairi nekukurumidza kana gare gare. Nekudaro, kazhinji izvi hazvichave maVega machipi, asi anofambira mberi anomhanyisa ane Navi architecture, iyo AMD inoronga kusuma kutanga muchikamu chechitatu.
Google Stadia inotarisirwa kutanga muna 2019 uye ichabvumira vanyoreri vesevhisi "kuyerera" mitambo kumidziyo yavo mu4K resolution ine furemu ye60 Hz.
