Ngenkathi iGoogle imemezela izifiso zayo ekusakazeni umdlalo kanye ... ukuthuthukiswa kwesevisi ye-Stadia, kuye kwaphakama imibuzo eminingi mayelana nemishini ezosetshenziswa umdondoshiya wokusesha endaweni yayo entsha yamafu. Iqiniso liwukuthi i-Google ngokwayo inikeze incazelo engacacile kakhulu yokucushwa kwehadiwe, ikakhulukazi ingxenye yayo yehluzo: empeleni, yathenjiswa kuphela ukuthi izinhlelo zokusakaza imidlalo kubasebenzisi benkonzo zizohlanganiswa kwezinye izisheshisi zehluzo ze-AMD ezinenkumbulo ye-HMB2. , amayunithi ekhompyutha angama-56 (CU) nokusebenza kwama-teraflops angu-10,7. Ngokusekelwe kule ncazelo, abaningi baye benza , ukuthi sikhuluma ngama-processor wehluzo we-7-nm AMD Vega, asetshenziswa kumakhadi wevidiyo we-Radeon VII wabathengi. Kepha imininingwane emisha ikhombisa ukuthi iStadia izosebenzisa amaVega GPU esizukulwane sokuqala afana neVega 56.
Ukugomela ngokuthi sikhuluma ngesizukulwane sokuqala i-Vega kuvunyelwe idatha evela kuwebhusayithi ye-Khronos, inhlangano ethuthukisa futhi ithuthukise i-Vulkan graphical interface. Njengoba kukhonjisiwe lapho, βi-Google Games Platform Gen 1β, okungukuthi, inkundla yezingxenyekazi zekhompiyutha kusevisi yesizukulwane sokuqala se-Stadia, izosebenzisana ne-Vulkan_1_1 sibonga ukusetshenziswa kwezakhiwo ze-AMD GCN 1.5 (GCN yesizukulwane sesihlanu). Futhi lokhu kusho ukuthi ama-GPU asetshenziswe kuleli cala ahambisana ngokwezakhiwo namakhadi evidiyo e-Vega okuqala asekelwe kuma-chips angu-14 nm, kuyilapho ama-Vega processors akamuva, akhiqizwa kusetshenziswa ubuchwepheshe benqubo ye-7 nm futhi asetshenziswa kumakhadi wevidiyo we-Radeon VII, ayingxenye ethuthukisiwe. izakhiwo GCN 1.5.1 (Isizukulwane 5.1).
Ngamanye amazwi, kubukeka sengathi i-AMD ilungiselela i-Google lutho ngaphandle kwenguqulo ekhethekile ye-Vega 56. Isimemezelo se-Stadia sathi ama-accelerator ezithombe zesevisi azothola ama-56 CUs, ukusebenza kwe-teraflops angu-10,7 kanye nenkumbulo ye-HBM2 enomkhawulokudonsa ongu-484 GB/ s. Ngaphezu kwalokho, kwathiwa inani eliphelele lememori yesistimu (i-RAM nememori yevidiyo isiyonke) izoba ngu-16 GB. Lokhu kungahunyushwa ngendlela yokuthi isisheshisi se-Stadia simane siyinguqulo ekhethekile ye-Vega 56 eno-8 GB HMB2 kanye nezandiso zenkumbulo ewumongo neyevidiyo.
Kuvele ukuthi i-AMD ibingakalokothi inikeze i-Google ukuthi isebenzise ama-chips we-7-nm Vega. Futhi lokhu kulula ukukuchaza: izixazululo ezivuthiwe nezivivinywe isikhathi kumongo wezinkontileka ezinkulu zokuhlinzeka ziyisixazululo esithembeke kakhulu. Ukwengeza, ngokunikeza inguqulo evuthiwe ye-14nm ye-Vega ye-Stadia, i-AMD izokwazi ukukhipha imali engenayo ephakeme kulesi sigaba futhi izivikele ezinkingeni ezingaba khona. Ukukhiqizwa kwama-chips we-14nm Vega kusungulwe kahle futhi kwenzeka ezikhungweni ze-GlobalFoundries, kuyilapho ama-oda okukhiqizwa kwama-chips angu-7nm kuzodingeka abekwe ne-TSMC, engadala izinkinga ezithile kokubili kwezinga lokukhiqiza lama-chips afanelekile namavolumu okukhiqiza.
Ngesikhathi esifanayo, akungabazeki ukuthi inkundla ye-Google Stadia izothuthuka, futhi ama-GPU akhishwe kusetshenziswa ubuchwepheshe be-7nm ngokusobala azofika kuwo maduze noma kamuva. Kodwa-ke, kungenzeka ukuthi lawa angeke esaba ama-Vega chips, kodwa ama-accelerator athuthukayo anezakhiwo ze-Navi, i-AMD ehlela ukuyethula kusukela ngekota yesithathu.
I-Google Stadia kulindeleke ukuthi yethulwe ngo-2019 futhi izovumela ababhalisile besevisi ukuthi "basakaze" imidlalo kumadivayisi abo ngesinqumo se-4K ngesilinganiso sozimele esingu-60 Hz.
