Dịka akụkụ nke ogbako GDC 2019, Google mere emume nke ya nke webatara ọrụ egwuregwu nkwanye ọhụrụ ya Stadia. Anyị ekwuworị banyere ọrụ ahụ n'onwe ya, ma ugbu a, anyị ga-achọ ịgwa gị n'ụzọ zuru ezu banyere otú usoro Google ọhụrụ si arụ ọrụ, n'ihi na ọ na-eji ngwọta dị iche iche emere kpọmkwem maka usoro a.
Isi ihe dị na sistemụ Google bụ, n'ezie, ndị nrụpụta eserese. N'ebe a, a na-eji ngwọta omenala sitere na AMD, nke dabere na ihe owuwu eserese Vega. A na-akọ na GPU ọ bụla nwere nkeji mgbakọ 56 (Compute Units, CU), ma nweekwa ebe nchekwa HBM2.
Ị nwere ike iche na Google na-eji kaadị ndịna-emeputa dị ka onye na-azụ ahịa Radeon RX Vega 56. Otú ọ dị, n'eziokwu, usoro omenala AMD nwere ọtụtụ ọdịiche dị mkpa. Nke mbụ, ọ na-eji ebe nchekwa ngwa ngwa na bandwit nke 484 GB / s. Onye na-azụ ahịa Radeon RX Vega 64 nwere otu ebe nchekwa ahụ, ebe Radeon RX Vega 56 nke obere na-eji ebe nchekwa dị obere (410 GB/s). Ka anyị mara ozugbo na mkpokọta ebe nchekwa dị na sistemụ ahụ bụ 16 GB, nke ọkara, nke doro anya, bụ ebe nchekwa vidiyo HBM2, nke ọzọ bụ DDR4 RAM.
Mana nke kachasị mkpa, Google na-ekwu na 10,7 teraflops nke arụmọrụ maka GPU ya, o doro anya na ngụkọ otu nkenke (FP32). Onye ahịa Radeon RX Vega 56 nwere ike naanị ihe dịka teraflops 8,3. Ọ ga-abụ ihe ezi uche dị na ya iche na ngwọta maka Google na-eji GPU ugboro ugboro. Nke a, n'aka nke ya, na-egosi na AMD ekepụtala ihe nrụpụta eserese maka Stadia na ihe owuwu Vega II emelitere, a na-emepụta ya site na iji teknụzụ usoro 7-nm.
Banyere onye nrụpụta, Google akọwapụtaghị ihe ngwọta onye nrụpụta ọ jiri na sistemụ ọrụ Stadia. Ọ na-ekwu naanị na nke a bụ ihe nhazi x86-dakọtara ọnụ na ugboro 2,7 GHz, yana 9,5 MB nke cache na ọkwa nke abụọ na nke atọ, yana yana multi-threading (Hyperthreading) na nkwado maka ntuziaka AVX2. Ogo cache na aha multithreading dị ka "HyperThreading" na-egosi na nke a bụ mgbawa Intel. Otú ọ dị, ịkwado naanị AVX2 na-enweghị AVX512 ọgbara ọhụrụ na-ezo aka na AMD, nke, ọzọkwa, a maara nke ọma maka ibe omenala ya. O yikarịrị ka AMD ọhụrụ 7nm Zen 7 ga-eji ihe nrụpụta dabere na 2nm Vega GPU.
Ndị a bụ sistemụ Google ga-enye ndị ọrụ nke ọrụ egwuregwu Stadia ọhụrụ ya. A ghaghị ikwu ọtụtụ ike ịgbakọ, mana ọ dị mkpa iji hụ na arụmọrụ dị elu na egwuregwu. Ọzọkwa, Google na-ezube ịnye egwuregwu na mkpebi ruo 4K na ugboro nke 60 FPS.
