Ayanda amahlebezi nokuvuza mayelana nemikhiqizo ezayo ye-AMD. Kulokhu, isiteshi se-YouTube i-AdoredTV yabelane ngedatha entsha mayelana nama-AMD Navi GPU azayo. Umthombo uhlinzeka ngedatha ngezici nezintengo zalo lonke uchungechunge olusha lwamakhadi evidiyo e-AMD, okuthi, ngokusho kwedatha etholakalayo, izobizwa ngokuthi i-Radeon RX 3000. Kuvela ukuthi uma ulwazi mayelana negama lulungile, khona-ke i-AMD izoba nayo. womabili amakhadi evidiyo namaphrosesa ochungechunge lwe-3000.
Ngakho-ke, ngokusho kwedatha eshicilelwe, amakhadi wevidiyo amancane esizukulwane esisha, i-Radeon RX 3060 ne-RX 3070, azokwakhiwa kuphrosesa yehluzo ye-Navi 12. Esimeni sokuqala, inguqulo ethize "ehlutshiwe" ye-GPU izoba. isetshenziswe namayunithi angama-32 eCompute (CU), okusho ukuba khona kwamaphrosesa okusakaza ka-2048. Imodeli enamandla kakhulu ibonakala inenguqulo egcwele ye-chip ene-40 CUs, okungukuthi, enama-processor okusakaza angu-2560.
Mayelana nokusebenza, i-Radeon RX 3060 izocishe ilingane ne-Radeon RX 580 yamanje, kuyilapho i-Radeon RX 3070 izolingana ne-Radeon RX Vega 56. Ngaphezu kwalokho, imikhiqizo emisha izodla amandla amancane kakhulu, njengoba ama-Navi GPU ekhona. yenziwe kusetshenziswa ubuchwepheshe benqubo ye-7 nm. Kubikwa ukuthi izinga le-TDP le-Radeon RX 3060 encane lizoba ngu-75 W kuphela, kanti i-Radeon RX 3070 izoba ngu-130 W. Amakhadi evidiyo azothola inkumbulo engu-4 no-8 GB yememori ye-GDDR6, ngokulandelana.
Amakhadi evidiyo e-Radeon amasha entengo emaphakathi azokwakhiwa kuma-GPU e-Navi 10. Ngokusho kwamahemuhemu, i-AMD ilungiselela amamodeli amathathu: i-Radeon RX 3070 XT, i-RX 3080 ne-RX 3080 XT. Eyokuqala izokwakhiwa ngenguqulo ye-GPU enama-48 CUs nama-3072 stream processors, eyesibili enguqulweni enama-52 CUs nama-3328 stream processors, futhi ekugcineni eyesithathu izohlinzeka ngama-CUs angu-56 kanye nama-3584 okusakaza. Kuyaziwa ukuthi imodeli yeRadeon RX 3080 izothola inkumbulo engu-8 GB ye-GDDR6, kodwa ngeshwa, akukho okwaziwayo okwamanje mayelana nokucushwa kwe-subsystem yememori kwamanye amamodeli.
Mayelana nokusebenza, i-Radeon RX 3070 XT izocishe ilingane ne-Radeon RX Vega 64. Imodeli ye-Radeon RX 3080 izonikeza amandla acishe abe ngu-10% engeziwe, futhi i-Radeon RX 3080 XT endala kufanele ihambisane ne-GeForce RTX 2070. Ngokuqondene nokusetshenziswa kwamandla, ngokomthombo, kuzoba ngu-160, 175 kanye no-190 W, ngokulandelana. Futhi uma iqhathaniswa neRadeon RX Vega 64, kukhona ukwanda okukhulu kokusebenza kahle. Kodwa iGeForce RTX 2070 efanayo inezinga eliphansi le-TDP - 175 W, uma iqhathaniswa ne-190 W ye-Radeon RX 3080 XT. Futhi lokhu kuyethusa ngandlela thize, kodwa, ngenhlanhla, i-AMD inekhadi elilodwa lecilongo, esizokhuluma ngalo ekugcineni.
Okwamanje, ake sisho amagama ambalwa mayelana nefulegi le-AMD lesikhathi esizayo. Azoba amakhadi evidiyo e-Radeon RX 3090 kanye ne-RX 3090 XT, akhelwe kuma-GPU e-Navi 20. Kuhle ukuqaphela zisuka nje ukuthi lawa ma-chips namakhadi evidiyo asekelwe kuwo azokhishwa kamuva, cishe ekupheleni kwalo nyaka noma ekuqaleni. wonyaka ozayo. Kungenzeka futhi ukuthi i-AMD iqale isebenzise i-Navi 20 kumadivayisi angochwepheshe, ikakhulukazi, ama-accelerator esikhathi esizayo e-Radeon Instinct computing, futhi ngemva kwalokho azovela kumakhadi wevidiyo wabathengi.
Kungakhathaliseki ukuthi kungenzeka, ngokusho komthombo, i-Radeon RX 3090 izothola inguqulo ye-GPU ene-3840 stream processors (60 CU), kuyilapho i-Radeon RX 3090 XT endala izohlinzeka ngenguqulo ephelele ye-chip ene-64 CU futhi, ngokufanele. , 4096 amaphrosesa wokusakaza. Ikhadi lemifanekiso le-Radeon RX 3090 lizolingana nokusebenza kwe-Radeon VII, kuyilapho i-Radeon RX 3090 XT izoshesha ngo-10%. Ngasikhathi sinye, izinga le-TDP lemikhiqizo emisha lizoba ngu-180 no-225 W, ngokulandelana, okuwukuthuthuka okukhulu uma kuqhathaniswa neRadeon VII kanye ne-295 W.
Kodwa, njengoba kushiwo ngenhla, isici esiyinhloko samakhadi wevidiyo we-AMD wesikhathi esizayo ngeke kube izici zawo, kodwa inani lawo. Ngokusho komthombo, imikhiqizo emisha ye-AMD ngeke ibize ngaphezu kuka-$500. Yebo, i-flagship enokusebenza okuphezulu kune-Radeon VII izobiza u-$500 kuphela. Futhi ukusebenza kwezinga le-GeForce RTX 2070 kungatholakala ngama- $330 nje nge-Radeon RX 3080 XT. Eminye imikhiqizo emisha izophinde ibe nenani elimnandi, kusukela ku-$ 140 ku-Radeon RX 3060 encane. Yiqiniso, uma amahlebezi eyiqiniso.
