Monga gawo la msonkhano wa GDC 2019, Google idachita chochitika chake pomwe idayambitsa ntchito yake yatsopano yotsatsira masewera a Stadia. Takambirana kale za ntchitoyi yokha, ndipo tsopano tikufuna kukuuzani mwatsatanetsatane momwe dongosolo latsopano la Google limagwirira ntchito, chifukwa limagwiritsa ntchito njira zosiyanasiyana zopangira dongosolo lino.
Chinthu chofunika kwambiri pa dongosolo la Google ndi, ndithudi, zojambula zojambula. Apa, mayankho achizolowezi ochokera ku AMD amagwiritsidwa ntchito, omwe amachokera ku Vega graphics architecture. Akuti GPU iliyonse ili ndi mayunitsi 56 apakompyuta (Compute Units, CU), ndipo ilinso ndi kukumbukira kwa HBM2.
Mungaganize kuti Google imagwiritsa ntchito makadi ojambula ofanana ndi ogula Radeon RX Vega 56. Komabe, kwenikweni, njira zothetsera chizolowezi za AMD zimakhala ndi zosiyana zingapo zofunika. Choyamba, imagwiritsa ntchito kukumbukira mwachangu ndi bandwidth ya 484 GB/s. Wogula Radeon RX Vega 64 ali ndi kukumbukira komweko, pamene Radeon RX Vega 56 wamng'ono amagwiritsa ntchito kukumbukira kochepa (410 GB / s). Tiyeni tiwone mwachangu kuti kuchuluka kwa kukumbukira mudongosolo ndi 16 GB, komwe theka, mwachiwonekere, ndi kukumbukira kwamavidiyo a HBM2, ndipo inayo ndi DDR4 RAM.
Koma chofunika kwambiri, Google imanena kuti 10,7 teraflops ya magwiridwe antchito ake a GPUs, mwachiwonekere mu kuwerengera kamodzi kokha (FP32). Wogula Radeon RX Vega 56 amatha pafupifupi 8,3 teraflops. Zingakhale zomveka kuganiza kuti mayankho a Google amagwiritsa ntchito ma GPU othamanga kwambiri. Izi, zikuwonetsa kuti AMD yapanga purosesa yazithunzi za Stadia pamapangidwe osinthidwa a Vega II, ndipo amapangidwa pogwiritsa ntchito ukadaulo wa 7-nm.
Ponena za purosesa, Google sinatchule yankho la wopanga lomwe idagwiritsa ntchito pamakina a Stadia. Amangonena kuti iyi ndi purosesa yogwirizana ndi x86 yokhala ndi ma frequency a 2,7 GHz, yokhala ndi 9,5 MB ya cache mugawo lachiwiri ndi lachitatu, komanso ndi ulusi wambiri (Hyperthreading) ndikuthandizira malangizo a AVX2. Kukula kwa cache ndi dzina la multithreading ngati "HyperThreading" zikuwonetsa kuti ichi ndi chipangizo cha Intel. Komabe, kuthandizira AVX2 yokha popanda AVX512 yamakono imatilozera ku AMD, yomwe, kuwonjezera apo, imadziwika bwino ndi tchipisi tawo. Ndizotheka kuti mapurosesa atsopano a 7nm Zen 7 a AMD agwiritsidwe ntchito limodzi ndi 2nm Vega GPU.
Awa ndi machitidwe omwe Google ipereka kwa ogwiritsa ntchito ake atsopano amasewera a Stadia. Mphamvu zambiri zamakompyuta ziyenera kunenedwa, koma ndikofunikira kuwonetsetsa kuti masewerawa achita bwino. Kuphatikiza apo, Google ikukonzekera kupereka masewera pazosintha mpaka 4K pafupipafupi 60 FPS.
