Xa uGoogle ebhengeza amabhongo akhe kumdlalo wokusasaza kunye ... uphuhliso lwenkonzo ye-Stadia, kuye kwavela imibuzo emininzi malunga nezixhobo eziza kusetyenziswa yi-giant yokukhangela kwi-platform yefu entsha. Inyani yeyokuba uGoogle ngokwakhe unike inkcazo engacacanga kakhulu yoqwalaselo lwehardware, ngakumbi icandelo layo lemizobo: enyanisweni, kwakuthenjiswe kuphela ukuba iinkqubo zokusasaza imidlalo kubasebenzisi benkonzo ziya kudityaniswa kwezinye ii-accelerator zegraphic ze-AMD ezinememori ye-HMB2. , iiyunithi ze-computing ezingama-56 (CU) kunye nokusebenza kwe-10,7 teraflops. Ngokusekelwe kule nkcazo, abaninzi baye benza , ukuba sithetha nge-7-nm ye-AMD Vega ye-graphics processors, esetyenziswa kubathengi amakhadi evidiyo e-Radeon VII. Kodwa ulwazi olutsha lubonisa ukuba uStadia uza kusebenzisa iVega GPU yesizukulwana sokuqala esifana neVega 56.
Ukuqinisekisa ukuba sithetha ngesizukulwana sokuqala iVega ivunyelwe yidatha evele kwiwebhusayithi yeKhronos, umbutho ophuhlisa kwaye uphuhlise ujongano lomzobo weVulkan. Njengoko kubonisiwe apho, "i-Google Games Platform Gen 1", oko kukuthi, iqonga le-hardware kwinkonzo ye-Stadia yesizukulwana sokuqala, iya kuhambelana ne-Vulkan_1_1 ngenxa yokusetyenziswa kwe-AMD GCN 1.5 ye-architecture (isizukulwana sesihlanu se-GCN). Kwaye oku kuthetha ukuba ii-GPU ezisetyenzisiweyo kulo mzekelo zihambelana ngokwezakhiwo kunye namakhadi evidiyo okuqala eVega asekwe kwi-chips ze-14 nm, ngelixa iiprosesa zeVega zamva, ziveliswe kusetyenziswa itekhnoloji yenkqubo ye-7 nm kwaye isetyenziswa kumakhadi evidiyo eRadeon VII, yeyomntu ophuculweyo. i-architecture GCN 1.5.1 (isizukulwana 5.1).
Ngamanye amazwi, kubonakala ngathi i-AMD ilungiselela i-Google nto ngaphandle kwenguqulo ekhethekileyo ye-Vega 56. Isibhengezo se-Stadia sathi i-graphics accelerators yenkonzo iya kufumana i-56 CUs, ukusebenza kwe-teraflops ye-10,7 kunye nememori ye-HBM2 kunye ne-bandwidth 484 GB / s. Ukongeza, kwathiwa inani elipheleleyo lememori yenkqubo (i-RAM kunye nememori yevidiyo iyonke) iya kuba yi-16 GB. Oku kunokutolikwa ngendlela yokuba i-accelerator ye-Stadia ibe yinguqulelo ekhethekileyo ye-Vega 56 ene-8 GB HMB2 kunye nokwandisa i-core kunye ne-memory memory frequencies.
Kuyavela ukuba i-AMD ayikhange ibe nabuganga bokubonelela uGoogle ukuba asebenzise iitshiphusi zeVega ze-7-nm. Kwaye oku kulula ukukucacisa: izisombululo ezivuthiweyo nezivavanywa ixesha kumxholo wekhontrakthi zobonelelo olukhulu zisisisombululo esithembeke ngakumbi. Ukongeza, ngokunikezela ngenguqulo ye-14nm evuthiweyo yeVega ye-Stadia, i-AMD iya kukwazi ukukhupha ingeniso ephezulu kweli nqanaba kwaye ikhuseleke kwiingxaki ezinokubakho. Ukuveliswa kweetshiphusi ze-14nm Vega kumiselwe kakuhle kwaye kwenzeka kwiindawo ze-GlobalFoundries, ngelixa ii-odolo zokuveliswa kweetshiphusi ze-7nm ziya kufuneka zibekwe kunye ne-TSMC, enokuthi idale iingxaki ezithile kunye nenqanaba lesivuno se-chips ezifanelekileyo kunye nemiqulu yemveliso.
Kwangelo xesha, akukho mathandabuzo ukuba iqonga leGoogle Stadia liya kukhula, kwaye iiGPU ezikhutshwe zisebenzisa itekhnoloji ye-7nm ngokuqinisekileyo ziya kuza kuyo kungekudala okanye kamva. Nangona kunjalo, kusenokwenzeka ukuba ezi azizukuphinda zibe ziitshiphusi zeVega, kodwa ziqhubela phambili ngakumbi i-accelerators nge-Navi Architecture, apho i-AMD iceba ukuyazisa ukuqala kwikota yesithathu.
I-Google Stadia kulindeleke ukuba iqalise ngo-2019 kwaye iya kuvumela ababhalisi benkonzo ukuba "baqhubele phambili" imidlalo kwizixhobo zabo kwisisombululo se-4K kunye nereyithi yesakhelo se-60 Hz.
