Isikhulu esiphezulu se-AMD uLisa Su ekuvulweni kweComputex 2019 ngokusobala ubengafuni ukugxila emakhadini evidiyo egeyimu omndeni wakwaRadeon RX 5700 oneNavi architecture (RDNA), kodwa ashicilelwe ngokulandelayo. kuwebhusayithi yenkampani ilethe ukucaciseleka okuthile kuzici zezixazululo ezintsha eziyingcaca. Ngenkathi uLisa Su ekhombisa esiteji iphrosesa yehluzo engu-7-nm enezakhiwo ze-Navi, ikristalu ye-monolithic engenawo ama-memory chips e-HBM2 aseduze yavele yaveza umqondo wokusebenzisa inkumbulo ye-GDDR6, imbangi ye-NVIDIA eyamukela ngonyaka odlule, yethula izixazululo zegraphics. umndeni weTuring.
Umhleli wesayithi uqale wabika ngokusetshenziswa kwe-AMD kwememori ye-GDDR6. URyan Smith ekhasini lakhe le-Twitter; izinkomba zakamuva zalolu hlobo lwenkumbulo zitholwe ekukhululweni kwabezindaba kuwebhusayithi yenkampani. Ngaphezu kwalokho, i-AMD igcizelele ukuthi ukwakheka kwe-RDNA ngeke kube isisekelo samakhadi wevidiyo wegeyimu kuphela, kodwa futhi nezixazululo zokusakaza imidlalo evela efwini, kanye nama-consoles wegeyimu emisha. Ngesikhathi ethula inkulumo yakhe eyisihluthulelo, uLisa Su uthe i-RDNA izoba wukwakhiwa kwezithombe ze-AMD kule minyaka eyishumi ezayo.
Kukhona neziqinisekiso ezisemthethweni amayunithi wokwenza ama-graphics processors, alethwe ukwakheka okusha kwe-RDNA. I-AMD ngokwayo ayikamenyezeli imininingwane mayelana nalezi zinguquko, kodwa ibika ukuthi i-RDNA inikeza ukwanda okungama-25% ekusebenzeni kwewashi ngalinye uma kuqhathaniswa ne-GCN, futhi isilinganiso sokusebenzisa amandla kuya kumandla sithuthuke ngo-50%. Phela, inkampani ngeke iwucime ukwakheka kwe-GCN; isazowusebenzisa engxenyeni yokusheshisa ikhompyutha.
Esithangamini sabezindaba ngemuva kwenkulumo yakhe, njengoba umthombo ucacisa , U-Lisa Su uqinisekise izinhloso zakhe zokukhuluma ngezinhlelo zokwethula i-ray tracing emidlalweni emcimbini we-E3 2019, ozosakazwa bukhoma ngoJuni XNUMX. Njengoba impendulo evela enhloko ye-AMD isho inkulumo mayelana nezinhlelo zekusasa engxenyeni yehluzo, kungacatshangwa ukuthi isizukulwane sokuqala se-Navi ngeke sithole ukwesekwa kokulandela umsebe ezingeni le-hardware - okungenani engxenyeni yevidiyo yedeskithophu. amakhadi.
