Ma ke ʻano o ka hālāwai kūkā GDC 2019, ua mālama ʻo Google i kāna hanana ponoʻī kahi i hoʻolauna ai i kāna lawelawe pāʻani streaming hou ʻo Stadia. Ua kamaʻilio mua mākou e pili ana i ka lawelawe ponoʻī, a i kēia manawa makemake mākou e haʻi iā ʻoe i nā kikoʻī hou aku e pili ana i ka hana ʻana o ka ʻōnaehana Google hou, no ka mea, hoʻohana ia i nā hoʻonā like ʻole i hana ʻia no kēia ʻōnaehana.
ʻO ka mea nui o ka ʻōnaehana Google, ʻoiaʻiʻo, nā mea hana kiʻi. Maʻaneʻi, hoʻohana ʻia nā hoʻonā maʻamau mai AMD, i hoʻokumu ʻia ma ka hoʻolālā kiʻi Vega. Ua hōʻike ʻia ʻo kēlā me kēia GPU he 56 mau ʻāpana helu (Compute Units, CU), a ua lako pū me ka hoʻomanaʻo HBM2.
Manaʻo paha ʻoe e hoʻohana ana ʻo Google i nā kāleka kiʻi e like me ka mea kūʻai aku ʻo Radeon RX Vega 56. Eia naʻe, ʻoiaʻiʻo, he mau ʻokoʻa koʻikoʻi ko nā ʻōnaehana maʻamau o AMD. ʻO ka mea mua, hoʻohana ia i ka hoʻomanaʻo wikiwiki me ka bandwidth o 484 GB / s. Loaʻa i ka mea kūʻai aku ʻo Radeon RX Vega 64 ka hoʻomanaʻo like, aʻo ka mea ʻōpio ʻo Radeon RX Vega 56 e hoʻohana i ka hoʻomanaʻo wikiwiki (410 GB / s). E hoʻomaopopo koke mākou i ka nui o ka hoʻomanaʻo i ka ʻōnaehana ʻo 16 GB, ʻo ia ka hapalua, ʻike ʻia, ʻo ia ka hoʻomanaʻo wikiō HBM2, a ʻo kekahi ʻo DDR4 RAM.
Akā ʻoi aku ka mea nui, ʻōlelo ʻo Google he 10,7 teraflops o ka hana no kāna mau GPU, ʻike ʻia i ka helu helu hoʻokahi (FP32). Hiki i ka mea kūʻai aku ʻo Radeon RX Vega 56 ke hiki i ka 8,3 teraflops. Maikaʻi ka manaʻo e hoʻohana nā hoʻonā no Google i nā GPU me ke alapine kiʻekiʻe. ʻO kēia, ma ka huli ʻana, hōʻike ʻia ua hana ʻo AMD i kahi kaʻina hana kiʻi no Stadia ma ka hoʻolālā Vega II hou, a ua hana ʻia me ka hoʻohana ʻana i kahi ʻenehana hana 7-nm.
ʻO ka mea hana, ʻaʻole ʻōlelo ʻo Google i ka hopena o ka mea hana i hoʻohana ai i nā ʻōnaehana lawelawe Stadia. Ke'ōlelo wale neiʻo ia he mea hana maʻamau x86-compatible me ka alapine o 2,7 GHz, me 9,5 MB o ka cache ma ka lua a me ke kolu o nā pae, a me ka multi-threading (Hyperthreading) a me ke kākoʻo no nā kuhikuhi AVX2. ʻO ka nui o ka cache a me ka inoa o ka multithreading e like me "HyperThreading" e hōʻike ana he chip Intel kēia. Eia nō naʻe, ʻo ke kākoʻo ʻana iā AVX2 wale nō me ka ʻole o ka AVX512 hou aʻe i kuhikuhi ʻole iā mākou i AMD, ʻo ia hoʻi, ʻoi aku ka maikaʻi o kona ʻike ʻia no kāna mau ʻāpana maʻamau. Manaʻo paha e hoʻohana ʻia nā kaʻina hana 7nm Zen 7 hou a AMD me ka 2nm Vega GPU.
ʻO kēia nā ʻōnaehana e hāʻawi ʻia e Google i nā mea hoʻohana o kāna lawelawe pāʻani hou ʻo Stadia. Pono e ʻōlelo ʻia he nui ka mana helu, akā pono e hōʻoia i ka hana kiʻekiʻe i nā pāʻani. Eia kekahi, hoʻolālā ʻo Google e hāʻawi i nā pāʻani i nā hoʻonā a hiki i 4K ma ke alapine o 60 FPS.
