Kukho amarhe amaninzi kunye nokuvuza malunga neemveliso ze-AMD ezizayo. Ngeli xesha, ijelo leYouTube iAdoredTV yabelane ngedatha entsha malunga ne-AMD Navi GPUs ezayo. Umthombo unikezela ngedatha kwiimpawu kunye namaxabiso oluhlu olutsha lwamakhadi evidiyo ye-AMD, leyo, ngokwedatha ekhoyo, iya kubizwa ngokuba yiRadeon RX 3000. Kuvela ukuba ukuba ulwazi malunga negama luchanekile, ngoko i-AMD iya kuba nayo. zombini amakhadi evidiyo kunye nabaqhubekekisi be-3000 series.
Ngoko, ngokwedatha epapashiweyo, amakhadi evidiyo amancinci esizukulwana esitsha, i-Radeon RX 3060 kunye ne-RX 3070, iya kwakhiwa kwiprosesa ye-graphics ye-Navi 12. Kwimeko yokuqala, inguqu ethile "ehluthiweyo" yeGPU iya zisetyenziswe kunye neeyunithi zeCompute ezingama-32 (CU), nto leyo ethetha ubukho be-2048 stream processors. Imodeli enamandla ngakumbi ibonakala inenguqu epheleleyo ye-chip kunye ne-40 CUs, oko kukuthi, kunye neeprosesa ze-stream ze-2560.
Ngokumalunga nokusebenza, iRadeon RX 3060 iya kuba malunga neRadeon RX 580 yangoku, ngelixa iRadeon RX 3070 iya kulingana neRadeon RX Vega 56. Ngaphezu koko, iimveliso ezintsha ziya kudla amandla amancinci kakhulu, kuba iiNavi GPUs. yenziwe kusetyenziswa iteknoloji yenkqubo ye-7 nm. Kuxelwa ukuba inqanaba le-TDP yeRadeon RX 3060 encinci iya kuba yi-75 W kuphela, ngelixa i-Radeon RX 3070 iya kuba yi-130 W. Amakhadi evidiyo aya kufumana i-4 kunye ne-8 GB yememori ye-GDDR6, ngokulandelanayo.
Amakhadi evidiyo eRadeon amatsha exabiso eliphakathi aya kwakhiwa kwiNavi 10 GPUs. Ngokutsho kwamahemuhemu, i-AMD ilungiselela iimodeli ezintathu: iRadeon RX 3070 XT, iRX 3080 kunye neRX 3080 XT. Eyokuqala iya kwakhiwa kwinguqulo ye-GPU kunye ne-48 CUs kunye ne-3072 i-processor stream processors, eyesibini kwi-version kunye ne-52 CUs kunye ne-3328 processors stream processors, kwaye ekugqibeleni yesithathu iya kunika i-56 CUs kunye ne-3584 processors. Kuyaziwa ukuba imodeli yeRadeon RX 3080 iya kufumana i-8 GB yememori ye-GDDR6, kodwa ngelishwa, akukho nto eyaziwayo malunga nokucwangciswa kwememori engaphantsi kwezinye iimodeli.
Ngokwendlela yokusebenza, iRadeon RX 3070 XT iya kuphantse ilingane neRadeon RX Vega 64. Imodeli yeRadeon RX 3080 iya kubonelela malunga ne-10% yamandla angaphezulu, kwaye iRadeon RX 3080 XT endala kufuneka ilingane neGeForce RTX 2070. Ngokuphathelele ukusetyenziswa kwamandla, ngokomthombo, kuya kuba yi-160, 175 kunye ne-190 W, ngokulandelanayo. Kwaye xa kuthelekiswa neRadeon RX Vega 64, kukho ukonyuka okukhulu ekusebenzeni kakuhle. Kodwa i-GeForce RTX 2070 efanayo inezinga eliphantsi le-TDP - 175 W, ngokuchasene ne-190 W ye-Radeon RX 3080 XT. Kwaye oku kuyothusa, kodwa, ngethamsanqa, i-AMD inekhadi elinye lexilongo, esiza kuthetha ngalo ekugqibeleni.
Okwangoku, masithi amagama ambalwa malunga neeflegi ze-AMD zexesha elizayo. Baya kuba ngamakhadi evidiyo eRadeon RX 3090 kunye ne-RX 3090 XT, eyakhelwe kwi-Navi GPUs 20. Kuyafaneleka ukuba uqaphele kwangoko ukuba ezi chips kunye namakhadi evidiyo asekelwe kuwo aya kukhutshwa kamva, mhlawumbi ekupheleni kwalo nyaka okanye ekuqaleni. wonyaka ozayo. Kwakhona kunokwenzeka ukuba i-AMD iya kuqala ukusebenzisa i-Navi 20 kwizixhobo zobuchwephesha, ngokukodwa, i-Radeon Instinct computing accelerators yexesha elizayo, kwaye emva koko baya kuvela kumakhadi evidiyo yabathengi.
Yiba nokuba kunjalo, ngokutsho komthombo, i-Radeon RX 3090 iya kufumana inguqulo ye-GPU kunye ne-3840 processors (60 CU), ngelixa i-Radeon RX 3090 XT endala iya kunika inguqu epheleleyo ye-chip kunye ne-64 CU kwaye, ngokufanelekileyo. , 4096 abaqhubekisi bomsinga. Ikhadi lemizobo yeRadeon RX 3090 iya kuba malunga nokulingana nokusebenza kwiRadeon VII, ngelixa iRadeon RX 3090 XT iya kuba yi-10% ngokukhawuleza. Ngelo xesha, inqanaba le-TDP leemveliso ezintsha liya kuba yi-180 kunye ne-225 W, ngokulandelanayo, okuphuculweyo okuphawulekayo xa kuthelekiswa neRadeon VII kunye ne-295 W.
Kodwa, njengoko kukhankanyiwe ngasentla, inqaku eliphambili lamakhadi evidiyo e-AMD ezayo ayiyi kuba yimpawu zabo, kodwa ixabiso labo. Ngokomthombo, iimveliso ezintsha ze-AMD aziyi kuxabisa ngaphezulu kwe-500 yeedola. Ewe, iflegi enomsebenzi ophezulu kuneRadeon VII iya kubiza kuphela i-500 yeedola. Kwaye i-GeForce RTX 2070-level performance ingaba ne-$330 nje ngeRadeon RX 3080 XT. Ezinye iimveliso ezintsha ziya kuba nexabiso elimnandi, ukusuka kwi-$ 140 encinci yeRadeon RX 3060. Ngokuqinisekileyo, ukuba amahemuhemu ayinyaniso.
