Eserese Google Stadia ga-adabere na ọgbọ mbụ AMD Vega

Mgbe Google kwuputara ebumnuche nke ya na nkwanye egwuregwu na… mara ọkwa mmepe nke ọrụ Stadia, ọtụtụ ajụjụ ebiliwo gbasara akụrụngwa nke nnukwu ọchụchọ ga-eji n'igwe ojii ọhụrụ ya. Nke bụ eziokwu bụ na Google n'onwe ya nyere nkọwa na-edoghị anya nke nhazi ngwaike, ọkachasị akụkụ eserese ya: n'ezie, e kwere nkwa na a ga-agbakọta sistemụ na-agbasa egwuregwu maka ndị ọrụ ọrụ na ụfọdụ ndị nrụpụta eserese AMD omenala nwere ebe nchekwa HMB2. , 56 computing units (CU) na arụmọrụ nke 10,7 teraflops. Dabere na nkọwa a, ọtụtụ emeela echiche, na anyị na-ekwu maka 7-nm AMD Vega ndị na-eme ihe ngosi eserese, nke a na-eji na kaadị vidiyo Radeon VII ndị ahịa. Mana ozi ọhụrụ na-egosi na Stadia ga-eji Vega GPU nke ọgbọ mbụ yiri Vega 56.

Iji kwupụta na anyị na-ekwu maka ọgbọ mbụ Vega na-anabata data sitere na webụsaịtị Khronos, otu nzukọ na-etolite ma na-emepe ihe ngosi eserese Vulkan. Dị ka e gosiri n'ebe ahụ, "Google Games Platform Gen 1", ya bụ, ngwaike n'elu ikpo okwu na mbụ Stadia ọrụ, ga-dakọtara na Vulkan_1_1 ekele iji AMD GCN 1.5 architecture (ise nke GCN). Ma nke a pụtara na GPU ndị a na-eji na nke a bụ ụkpụrụ kwekọrọ na kaadị vidiyo Vega mbụ dabere na ibe 14 nm, ebe ndị na-emepụta Vega mechara, nke ejiri teknụzụ usoro 7 nm mepụta ma jiri ya na kaadị vidiyo Radeon VII, bụ nke emelitere. architecture GCN 1.5.1 (ọgbọ 5.1).

N'ikwu ya n'ụzọ ọzọ, ọ dị ka AMD na-akwado Google ọ dịghị ihe ọzọ karịa ụdị pụrụ iche nke Vega 56. Nkwupụta Stadia kwuru na ndị na-eme ihe nkiri maka ọrụ ahụ ga-enweta 56 CUs, 10,7 teraflops arụmọrụ na HBM2 ebe nchekwa na bandwit 484 GB / s. Na mgbakwunye, ekwuru na ngụkọta ego nke ebe nchekwa sistemụ (RAM na ebe nchekwa vidiyo na mkpokọta) ga-abụ 16 GB. Enwere ike ịkọwa nke a n'ụzọ ga-eme ka onye na-eme ngwa ngwa maka Stadia bụ naanị ụdị Vega 56 pụrụ iche nwere 8 GB HMB2 yana mmụba isi na ugboro ebe nchekwa vidiyo.

Ọ tụgharịrị na AMD ka anwaghị anwa inye Google ka o jiri 7-nm Vega ibe. Ma nke a dị nnọọ mfe ịkọwa: ngwọta tozuru okè na nke a nwalere oge n'ọnọdụ nke nnukwu nkwekọrịta ọkọnọ bụ ihe ngwọta a pụrụ ịdabere na ya. Na mgbakwunye, site n'inye ụdị Vega 14nm tozuru oke maka Stadia, AMD ga-enwe ike wepụta ego ha ga-enweta na ọkwa a wee chebe onwe ya pụọ ​​​​na nsogbu ndị nwere ike. Mmepụta nke ibe 14nm Vega guzosiri ike ma na-eme na akụrụngwa nke GlobalFoundries, ebe a ga-etinye iwu maka imepụta ibe 7nm na TSMC, nke nwere ike mepụta ụfọdụ nsogbu na ma ọkwa mkpụrụ nke ibe dabara adaba na mpịakọta mmepụta.

N'otu oge ahụ, obi abụọ adịghị ya na ikpo okwu Google Stadia ga-etolite, na GPU ndị ewepụtara site na iji teknụzụ 7nm ga-abịakwute ya n'oge na-adịghị anya. Agbanyeghị, o yikarịrị ka ndị a agaghị abụ ibe Vega, mana ndị na-aga n'ihu na-aga n'ihu na ụkpụrụ ụlọ Navi, nke AMD na-ezube iwebata ịmalite na nkeji nke atọ.

A na-atụ anya na Google Stadia ga-amalite na 2019 ma nye ndị debanyere aha ọrụ ahụ ohere ka ha "gbanye" egwuregwu na ngwaọrụ ha na mkpebi 4K na ọnụego etiti nke 60 Hz.
