Ikhadi lemizobo le-AMD Navi lekhadi lePCB libonisa ibhasi ye-256-bit kunye ne-GDDR6

I-AMD kungekudala iza kwazisa isizukulwana sayo esilandelayo se-Navi ye-accelerator ye-graphics cards ye-Radeon, eya kujoliswa kwiiPC zokudlala zedesktop. Nangona isibhengezo sicwangciselwe i-27 kaMeyi, umfanekiso wokuqala webhodi yekhadi levidiyo ye-AMD Radeon RX ezayo esekelwe kwi-architecture ye-Navi ibonakala kwi-Intanethi. Kubonakala ngathi oku kuluhlu oluphakathi okanye isisombululo esiphezulu, kuba i-PCB ibonisa ukusetyenziswa kwebhasi ye-256-bit kunye nememori ye-GDDR6. Kuyabonakala ukuba, sithetha ngekhadi levidiyo le-7nm, lenzelwe ukuba libe ngumlandeli wokwenene weRadeon RX 480.

Ukuba ujonga ngokusondeleyo kwiinkcukacha, ungabona i-BGA elungisiweyo (i-ball grid array) iipads zokuthengisa eyona chip yeGPU kunye nememori yevidiyo. Ngelishwa, akunakwenzeka ukuthetha ngokuqinisekileyo ukuba luhlobo luni lwekristale esithetha ngalo, kodwa iya kuba sisisombululo esinemveliso kakhulu. Ii-BGA ezisibhozo zeetshiphusi zeememori ziyabonakala malunga nendawo ye-GPU. Inani lezikhonkwane kwi-BGA nganye yeetshiphusi zememori yi-180, ngoko sithetha nge-GDDR6. Ke, i-accelerator ene-PCB iya kuba yimveliso yokuqala ye-AMD Radeon ukusebenzisa i-GDDR6.

Izikhonkwane ezi-8 zememori yevidiyo zikwabonisa i-256-bit bandwidth. Mhlawumbi ikhadi liya kubekwa njengokhuphiswano kwi-NVIDIA GeForce RTX 2070, enebhasi ye-256-bit kunye ne-8 GB yememori yevidiyo ye-GDDR6. Kuphela icala elingaphambili lebhodi yesekethe eprintiweyo inabafowunelwa be-BGA beememori zeechips, ngoko ke i-accelerator iya kulinganiselwa kwi-8 GB yememori yevidiyo.

Ngokubhekiselele kumandla, ikhadi lixhasa i-VRM yesigaba se-8 kwaye amandla anikezelwa nge-slots ezimbini ze-PCIe. Izikhonkwane zibonisa ukuba kunokwenzeka ukufaka izixhumi ezimbini ze-8-pin, kodwa abavelisi banokuzisebenzisa kwii-6-pin connectors. Kungenzeka ukuba olu luguqulelo lwakwangoko lwe-PCB ye-AMD ye-accelerator yexesha elizayo, enokutshintsha.

Kuyaziwa ukuba i-AMD Navi iya kuxhasa ukulandelwa kwe-ray (enye yezinto eziphambili isizukulwana esilandelayo intuthuzelo evela kwaSony). Kwaye kwaxelwa ukuba amakhadi evidiyo ane-architecture ye-Navi aya kufumana inkxaso Amanqanaba aguqukayo angaguqulwanga. Le teknoloji yi-analogue ye-NVIDIA Adaptive Shading kwaye yenzelwe ukugcina izixhobo zekhadi levidiyo. Ikuvumela ukuba unciphise umthwalo xa ubala izinto ze-peripheral kunye nemimandla ngokunciphisa ukuchaneka kwezibalo.

Isibhengezo esisemthethweni samakhadi egraphics e-7nm Navi kunye ne-7nm Ryzen 3000 processors kulindeleke ngoMeyi 27 kumboniso okhethekileyo kumsitho weComputex 2019, oza kubanjwa yi-CEO ye-AMD uLisa Su.
