Uma ukholelwa la mahemuhemu, kusho ukuthi sekusele cishe inyanga eyodwa nengxenye noma ezimbili ngaphambi kokumenyezelwa okusemthethweni kwamaphrosesa wezithombe ze-AMD Navi namakhadi evidiyo eRadeon asekelwe kuwo. Yiqiniso, njengoba isimemezelo sisondela, ukugeleza kwamahemuhemu nokuvuza mayelana nemikhiqizo emisha yesikhathi esizayo kuyanda. Umjikelezo olandelayo wamahemuhemu wembula izici zekhadi levidiyo le-Radeon RX 3080 lesikhathi esizayo - umlandeli weRadeon RX 580.
Yiqiniso, ngingathanda ngokushesha ukusho amazwi ambalwa mayelana nomthombo walokhu kuvuza. Lona umsebenzisi wensiza ongaziwa , othi usebenzela i-AMD nokuthi ulwazi alunikezayo kufanele okungenani lube olunembile ngo-99%. Ngakho-ke, wonke umuntu ake azinqumele ukuthi angawethemba kangakanani umthombo onjalo. Sizoncoma ukuthatha ulwazi olungezansi ngohlamvu lukasawoti, ukuze uma kuvela ukuthi lungamanga, ngeke udumale, futhi uma kuvela kuyiqiniso, uzomangala ngokujabulisayo.
Ngakho-ke, ngokomthombo, ama-Navi GPUs akhelwe ekwakhiweni kwesizukulwane esisha, esithathe indawo ye-Graphics Core Next (GCN). Izobizwa nge-Next Generation Geometry (NGG) futhi izosebenzisa i-pixel shading ephumelelayo (Draw Stream Binning Rasterizer).
Futhi umehluko obalulekile ekwakhiweni kwakudala kuzoba ngu-32 KB wenqolobane yezinga lokuqala, okungukuthi, kabili kunangaphambili. Futhi ivolumu yenqolobane yezinga lesibili le-Navi 10 GPU ecatshangelwa lapha izoba ngu-3076 KB. Ibhasi elingu-256-bit lisazosetshenziswa ukuxhuma inkumbulo, kodwa umkhawulokudonsa wesistimu engaphansi yememori izokhuphuka ibe ngu-410 GB/s, okubonisa ukusetshenziswa kwememori ye-GDDR6, nakuba ishesha kancane kunakuma-accelerator e-GeForce RTX.
Ngeshwa, umthombo awucacisi inombolo yamayunithi ekhompyutha we-Navi 10 GPU. Ijubane lewashi le-GPU kuphela elinikezwayo, elizoba ngaphezu kuka-1,8 GHz kumodi ye-Boost. Kulokhu, izinga le-TDP akufanele lidlule ku-150 W. Umthombo uphinde uphawule ukuthi ukusebenza kwekhadi levidiyo leRadeon RX 3080 kuzoba sezingeni phakathi kweRadeon RX Vega 56 neGeForce GTX 1080. Akuzwakali kuhlaba umxhwele kakhulu. Kodwa into ekhona ukuthi leli khadi levidiyo lizothengiswa ngama- $259 kuphela (intengo enconyiwe). Lesi silinganiso sokusebenza kwentengo senza umkhiqizo omusha ube ukusheshisa okuthakaselayo kubasebenzisi abaningi.
