Leaked AMD Navi graphics kadhi PCB mufananidzo unoratidza 256-bit bhazi uye GDDR6

AMD ichakurumidza kuunza chizvarwa chayo chinotevera Navi graphics accelerators yeRadeon graphics makadhi, ayo anozove akanangana nemaPC ekutamba desktop. Kunyangwe chokwadi chekuti chiziviso chakarongerwa Chivabvu 27, mufananidzo wekutanga webhodhi remangwana AMD Radeon RX vhidhiyo kadhi yakavakirwa paNavi dhizaini yakabuda paInternet. Zvinoita senge iyi ipakati-renji kana kunyange yakakwirira-yekupedzisira mhinduro, nekuti PCB inoratidza kushandiswa kwe256-bit bhazi uye GDDR6 ndangariro. Sezviri pachena, tiri kutaura nezve 7nm vhidhiyo kadhi, iyo inotarisirwa kuve mutsivi chaiye weRadeon RX 480.

Kana iwe ukanyatsotarisisa pane izvo, iwe unogona kuona yakagadzirirwa BGA (bhora gidhi array) mapedhi ekutengesa iyo huru GPU chip uye vhidhiyo memory. Nehurombo, hazvibviri kutaura chokwadi kuti rudzii rwekristaro rwatiri kutaura nezvarwo, asi ingangove iri mhinduro inobudirira. Eight BGAs endangariro machipisi anoonekwa akatenderedza GPU tsoka. Huwandu hwepini paBGA yendangariro machipisi i180, saka tiri kutaura nezve GDDR6. Nekudaro, inomhanyisa nePCB iyi ichave yekutanga AMD Radeon chigadzirwa kushandisa GDDR6.

Iyo 8 vhidhiyo yekurangarira pini inoratidzawo 256-bit bandwidth. Zvichida kadhi richaiswa semukwikwidzi kuNVIDIA GeForce RTX 2070, iyo zvakare ine 256-bit bhazi uye 8 GB yeGDDR6 vhidhiyo memory. Iro chete divi rekumberi redhidhi redunhu rakadhindwa rine maBGA mamemory machipisi, saka iyo accelerator ingangove inogumira ku8 GB yevhidhiyo memory.

Panyaya yesimba, kadhi rinotsigira 8-chikamu VRM uye simba rinopihwa kuburikidza maviri PCIe slots. Mapini anoratidza mukana wekuisa maviri 8-pini zvibatanidza, asi vagadziri vanogona kuzvishandisa kune 6-pini yekubatanidza. Zvinogoneka kuti iyi inguva yekutanga vhezheni yePCB yeramangwana AMD accelerator, iyo inogona kuramba ichichinja.

Izvo zvinozivikanwa kuti AMD Navi inotsigira ray tracing (imwe yeakakosha maficha chizvarwa chinotevera chinonyaradza kubva kuna Sony) Zvakataurwawo kuti makadhi evhidhiyo ane Navi architecture achawana rutsigiro Variable Rate Shading. Iyi tekinoroji ndeyeanalogue yeNVIDIA Adaptive Shading uye yakagadzirirwa kuchengetedza vhidhiyo kadhi zviwanikwa. Inokutendera kuti uderedze mutoro paunenge uchiverenga zvinhu zvekutenderera uye nzvimbo nekudzikisa kurongeka kwekuverenga.

Chiziviso chepamutemo che7nm Navi mifananidzo yemakadhi uye 7nm Ryzen 3000 processors inotarisirwa muna Chivabvu 27 pane yakakosha mharidzo pachiitiko cheComputex 2019, chichaitwa ne AMD CEO Lisa Su.
