Iminyaka ethile, I-AMD isilele ngemuva kukaNvidia emjahweni wamakhadi emidwebo ephezulu yokudlala.
Yebo, ngokuhamba kwesikhathi, abasebenzi be-AMD bagxilise ukunaka kwabo kanye nemizamo yabo engxenyeni yamakhadi emidwebo ebanga eliphakathi, egxile kwimikhiqizo yokumaketha efana ne-RX 470 noma kamuva nje, i-RX 590 ihlose ukubhekela umdlalo we-1080p.
Ngesikhathi se-CES 2019 kwenziwe ezinsukwini ezimbalwa ezedlule eVegas, Ithimba le-AMD lisebenzise ithuba lokwethula emphakathini uchungechunge olusha lwe-Vega GPU oluzuzayo ngenqubo yokuqopha eyi-7 nm kusuka ku-TSMC, esikhundleni se-14nm njengoba kubonakala ngeVega GPU yangaphambilini yomkhiqizo.
Lokhu kukhishwa okusha kwale AMD GPU entsha obizwa ngoRadeon VII (Isikhombisa), ukubhekisa esizukulwaneni sesibili iVega GPU ihlanganiswe ne-7nm TSMC, bekungukubuyela kwe-AMD emncintiswaneni emakethe yekhadi lemidwebo ephezulu.
Mayelana neRadeon VII entsha
Ngokusho kwe-AMD, ukwakhiwa kwaleli khadi lesithombe sesizukulwane sesibili iVega elisetshenziswe yiRadeon VII kunikeza ukusebenza okungaphezulu okungu-20-42% ngokuya ngesimo sokudlala nokusetshenziswa kuqhathaniswa neVega 64 GPU.
Ngisho kungaba ku-25% ngokusebenza kahle, njengabokugcina abanamandla alinganayo (e-Fortnite nase-Battlefield V, ngokwesibonelo), okungenzeka kube ukubuya komjaho we-AMD wemidlalo ye-4K.
Ehlangothini lweshidi lakho lobuchwepheshe, kufanele kuqashelwe ukuthi lesekethe yehluzo entsha inezinyunithi ezingama-60 zokubala (CU), imifudlana engu-3840 evalelwe ku-1.8 GHz, 16 GB yememori ye-HBM2, ibhasi lememori le-4096-bit, i-240 TMU, i-64 ROP, ne-bandwidth yememori ye-1 TB / s.
Ikhadi lemidwebo elisha elenziwe ngabakwa-AMD «I-Radeon VII »izofana ne-AMD's Radeon Instinct MI60 ne-MI50 GPUs ethulwe ezinyangeni ezimbalwa ezedlule.
Lezi zisuselwa kwimidwebo yeVega 20 exhaphaza inqubo ye-TSMC's 7nm etching. Zithwala kuze kufike ku-32 GB wememori ye-ECM HBM2, zinomkhawulokudonsa omkhulu we-1 TB / kuze kufike kuma-transistor angama-13.2 billion.
Ifulegi elisha le-AMD cishe alifanisi ukusebenza kahle kukaphethiloli wama-GPU ancintisanayo we-NVIDIA, njengoba iqembu le-AMD libonakala lingenandaba nenzuzo yezobuchwepheshe yamakhadi ancintisanayo e-NVIDIA kule ndawo.
Ngeke futhi uzuze ekusetshenzisweni kwe-DirectX Raytracing (DXR), isici esingakabi yinto ephambili eqenjini.
I-AMD isusa umbango wayo ne-NVIDIA
Leli khadi lemidwebo leRadeon VII elisha lizoqhudelana ngqo nekhadi lemidwebo likaNvidia's RTX 2080.
Yebo, ngokusho kwamagama aqondile abasebenzi be-AMD, futhiLokhu kufanele kunikeze izinga lokusebenza eliqhathaniswa noma elingcono kancane kune-NVIDIA RTX 2080, ngaphandle kokukhathazeka nge-RTX 2080 Ti.
Leli ikhadi le-Radeon hhayi ikhadi le-Radeon Pro, kepha i-AMD ilindele ukuzuza okufanayo kokufana nomdlalo wePro ngaleli khadi elisha (kuze kufike ku-62% ukusebenza). ngaphezu kwe-Open CL).
Ukusebenza kufanele kuthuthuke, ikakhulukazi njengoba umthwalo womsebenzi uhlobene namaphikseli noma umkhawulokudonsa wememori.
I-Radeon VII kulindeleke ukuthi ingene ngokusemthethweni emakethe ngenyanga ezayo cishe ngama- $ 699, ngethemba lokuthi i-AMD izobhekana nezinkinga zokuhlinzekwa nokulawulwa kwamanani ezikhungethe ukwethulwa kwamaVega 56 kanye nama-64 GPUs ngonyaka odlule.
Inkampani yaseSunnyVale nayo ihlela ukuqhudelana neNvidia ngokunikela ngeRadeon VII entsha ngenqwaba entsha efaka ikhophi yamahhala yale midlalo elandelayo: Resident Evil 2, Devil May Cry 5 kanye neThe Division 2.
Ngokunjalo, amanye amakhompyutha ane-GPU efakiwe nawo angahle afakwe omunye wemidlalo yevidiyo.
Lokho kuzohambisana nezibuyekezo ze- Abashayeli be-AMDGPU ngeLinux futhi, ukuthola okuningi ekusebenzeni kweLinux
