Namuhla ekuvulweni kweComputex 2019, i-AMD ibuke kuqala umndeni wayo we-Navi okade ulindelwe wamakhadi wevidiyo wegeyimu. Uchungechunge lwemikhiqizo emisha lwathola igama lokumaketha elithi Radeon RX 5000.
Kuyafaneleka ukukhumbula ukuthi umbuzo bekungenye yezimanga eziyinhloko lapho wethula izinketho zemidlalo ye-Navi. Nakuba ekuqaleni bekucatshangwa ukuthi i-AMD izosebenzisa izinkomba zezinombolo ezivela ochungechungeni lwe-5000, inkampani yagcina ikhethe igama elithi Radeon RX 50. Umbono waleli gama ukuthi idlala ngendikimba yokugubha iminyaka engu-XNUMX i-AMD igubha kulo nyaka. .
Ngaphezu kwalokho, kwavezwa omunye umniningwane othakazelisayo. Amakhadi evidiyo e-Radeon RX 5000 asekelwe esakhiweni esisha se-GPU esibizwa nge-Radeon DNA (RDNA), okuwukuthuthukiswa okuqhubekayo kwe-Graphics Core Next (GCN) eyavela eminyakeni eyisikhombisa edlule.
Isakhiwo se-RDNA sibonakala sinikeza idizayini entsha yeyunithi eyinhloko ye-GPU, iyunithi yekhompyutha, okuholela ekuthuthukisweni kokusebenza kahle kwamandla nokusebenza kwewashi ngalinye. Ngaphezu kwalokho, i-AMD isebenzise uhlelo olusha lwenqolobane olunamazinga amaningi ku-RDNA, okufanele lunciphise ukubambezeleka, lwandise ukuphuma, futhi luthuthukise nokusetshenziswa kwamandla. Iphayiphi lemifanekiso ye-RDNA elungiselelwe iphinde ivumele amakhadi amasha ezithombe ukuthi asebenze ngesivinini esiphezulu sewashi kunangaphambili, okuholela kumazinga aphezulu okusebenza. Ngaphezu kwalokho, uma kuqhathaniswa nama-chips ane-architecture ye-GCN, i-Navi inosayizi we-chip ohlangene we-semiconductor, kodwa kuze kube manje umenzi akakayidaluli imininingwane ngokuthi yimalini.
Sekukonke, i-architecture ye-RDNA ihlinzeka ngokusebenza okukhulu nokubambezeleka okuphansi ngezindleko ezingcono kakhulu. Uma kuqhathaniswa nesakhiwo sekhadi le-Vega, i-AMD ithembise ukukhuphuka ngamaphesenti angama-25 ekusebenzeni okuthile ngewashi ngalinye kanye nokwenyuka kwamaphesenti angama-50 ekusebenzeni okuthile ngewathi ngayinye.
Njengoba kumenyezelwe esethulweni, iphuzu lokuqala lokusetshenziswa kwesakhiwo esisha se-RDNA kuzoba uchungechunge lwamakhadi e-Radeon RX 5000, lapho kuzokhishwa khona amakhadi evidiyo okuqala abizwa ngokuthi i-Radeon RX 5700. Lonke uchungechunge luzosekelwe ku-Navi chips. , ekhiqizwa kusetshenziswa ubuchwepheshe benqubo ye-7-nm ezikhungweni ze-TSMC.
Isici esiphawuleka kakhulu sochungechunge lwe-Radeon RX 5000 kuzoba ukwesekwa kwabo kwebhasi le-PCI Express 4.0. I-AMD iwukhuthaza ngenkuthalo umbono wokudlulela enguqulweni entsha yesixhumi esibonakalayo enomkhawulokudonsa okhuphukile, futhi iRadeon RX 5000 izongena kahle ku-ecosystem yenkampani kanye namaphrosesa esizukulwane sesithathu seRyzen namabhodi omama asekelwe ku-chipset ye-X570.
Enkulumweni yakhe, isikhulu se-AMD uLisa Su ukhombise kafushane ukusebenza kwekhadi levidiyo lokudlala elisuselwa ku-chip ye-Navi. Ikhadi lemifanekiso le-Radeon RX 5700 liqhathaniswe ne-NVIDIA GeForce RTX 2070 kubhentshimakhi ye-Strange Brigade. Ngasikhathi sinye, umkhiqizo omusha we-AMD obelindelwe uvele waba ngokushesha ngo-10%.
I-AMD ihlose ukuqala ukuthengisa amakhadi evidiyo e-Radeon RX 5700 ngoJulayi, kodwa usuku oluthile alukamenyezelwa. Kodwa-ke, i-AMD ithembise ukwembula imininingwane eyengeziwe mayelana nama-specs, amanani, nokusebenza kwe-Navi emcimbini wayo we-Next Horizon Gaming e-E3 ngoJuni 10, 2019.
