Njengenxalenye yenkomfa ye-GDC 2019, uGoogle ubambe owayo umsitho apho wazisa ngenkonzo yakhe entsha yokusasaza umdlalo weStadia. Sele sithethile ngenkonzo ngokwayo, kwaye ngoku singathanda ukukuxelela ngakumbi malunga nendlela inkqubo entsha yeGoogle isebenza ngayo, kuba isebenzisa izisombululo ezahlukeneyo ezenzelwe le nkqubo.
Into ephambili yenkqubo kaGoogle, kunjalo, iprosesa yemizobo. Apha, izisombululo zesiko ezivela kwi-AMD zisetyenziswa, ezisekelwe kwi-architecture ye-Vega yemizobo. Kuxelwa ukuba i-GPU nganye ineeyunithi ze-computing ze-56 (i-Compute Units, CU), kwaye ixhotyiswe ngememori ye-HBM2.
Unokucinga ukuba iGoogle isebenzisa amakhadi egraphics afana nomthengi uRadeon RX Vega 56. Nangona kunjalo, enyanisweni, izisombululo zesiko le-AMD zineeyantlukwano ezininzi ezibalulekileyo. Okokuqala, isebenzisa imemori ekhawulezayo kunye ne-bandwidth ye-484 GB / s. Umthengi u-Radeon RX Vega 64 unememori efanayo, ngelixa i-Radeon RX Vega 56 encinci isebenzisa imemori engaphantsi ngokukhawuleza (410 GB / s). Masiqaphele ngokukhawuleza ukuba inani elipheleleyo lememori kwinkqubo yi-16 GB, apho isiqingatha, ngokucacileyo, imemori yevidiyo ye-HBM2, kwaye enye i-DDR4 RAM.
Kodwa okona kubaluleke kakhulu, uGoogle ubanga i-10,7 teraflops yokusebenza kwii-GPU zayo, ngokucacileyo kwizibalo ezichanekileyo (FP32). Umthengi weRadeon RX Vega 56 uyakwazi kuphela malunga ne-8,3 teraflops. Kuya kuba sengqiqweni ukucinga ukuba izisombululo zikaGoogle zisebenzisa ii-GPUs ezinomthamo ophezulu. Oku, kwakhona, kubonisa ukuba i-AMD yenze iprosesa yemizobo ye-Stadia kwi-architecture ehlaziyiweyo yeVega II, kwaye iveliswa kusetyenziswa iteknoloji yenkqubo ye-7-nm.
Ngokuphathelele iprosesa, uGoogle akacacisi ukuba yeyiphi isisombululo somenzi esisetyenzisiweyo kwiinkqubo zenkonzo yeStadia. Ithi kuphela iprosesa ye-x86 ehambelanayo kunye ne-frequency ye-2,7 GHz, kunye ne-9,5 MB ye-cache kwinqanaba lesibini nelesithathu, kunye ne-multi-threading (i-Hyperthreading) kunye nenkxaso ye-AVX2 imiyalelo. Ubungakanani be-cache kunye negama le-multithreading njenge "HyperThreading" ibonisa ukuba le yi-Intel chip. Nangona kunjalo, ukuxhasa kuphela i-AVX2 ngaphandle kwe-AVX512 yangoku ngakumbi isibhekisa ngokungangqalanga kwi-AMD, ethi, ngaphezu koko, yaziwa ngcono ngeetshiphusi zayo zesiko. Kusenokwenzeka ukuba iiprosesa ezisekwe kwi-7nm Zen 7 ze-AMD ziya kusetyenziswa kunye ne-2nm Vega GPU.
Ezi ziinkqubo uGoogle aza kuzibonelela kubasebenzisi benkonzo yakhe entsha yokudlala iStadia. Amandla amaninzi ekhompyuter kufuneka athi, kodwa kuyafuneka ukuqinisekisa ukusebenza okuphezulu kwimidlalo. Ngaphezu koko, uGoogle uceba ukubonelela ngemidlalo kwizisombululo ukuya kuthi ga kwi-4K ngokuphindaphindiweyo kwe-60 FPS.
