AMD CEO Lisa Su pakuvhurwa kweComputex 2019 zvakajeka aisada kutarisa pamakadhi evhidhiyo emitambo yeRadeon RX 5700 mhuri ine Navi architecture (RDNA), asi yakaburitswa inotevera. pawebhusaiti yekambani yakaunza kumwe kujekeswa kune maficha eiyo graphic mhinduro. Lisa Su paakaratidza pachikuva 7-nm graphics processor ine Navi architecture, iyo monolithic crystal isina pedyo HBM2 memory chips yakabva yapa pfungwa yekushandisa GDDR6 memory, iyo inokwikwidza NVIDIA yakagamuchirwa gore rapfuura, ichipa magiraidhi mhinduro dze. mhuri Turing.
Iyo saiti mupepeti yakatanga kutaura nezvekushandiswa kwe AMD kweGDDR6 memory. Ryan Smith pane yake Twitter peji; gare gare mareferensi erudzi urwu rwendangariro akawanikwa mukuburitswa kwenhau pawebhusaiti yekambani. Pamusoro pezvo, AMD yakasimbisa kuti iyo RDNA dhizaini ichaita hwaro kwete chete yemakadhi evhidhiyo emitambo, asiwo mhinduro dzemitambo yekutepfenyura kubva mugore, pamwe nemitambo mitsva yemitambo. Panguva yekutaura kwake, Lisa Su akataura kuti RDNA ichave AMD yekuenda-kune mifananidzo yekuvaka kwemakore gumi anotevera.
Kune zvakare zvisimbiso zvepamutemo execution units of graphics processors, ayo akaunzwa neiyo itsva RDNA architecture. AMD pachayo haisati yazivisa nezve shanduko idzi, asi inoshuma kuti RDNA inopa 25% kuwedzera kwekuita pawachi imwe neimwe kana ichienzaniswa neGCN, uye chiyero chekushandisa-kusimba-simba chakavandudzwa ne50%. Nenzira, kambani haisi kuzonyora GCN dhizaini; icharamba ichishanda muchikamu chekuwedzera komputa.
Pamusangano wevatori venhau mushure mekutaura kwake, sekujekesa kunojekesa . Sezvo mhinduro kubva kumusoro we AMD yaireva kutaura nezve hurongwa hweramangwana muchikamu chemifananidzo, zvinogona kufungidzirwa kuti chizvarwa chekutanga cheNavi hachizogashira ray yekutevera rutsigiro padanho rehardware - zvirinani muchikamu chevhidhiyo yedesktop. makadhi.
