Idatha yendawo yokufa ye-AMD Navi izoqeda ukuzethemba kwe-NVIDIA kumnyombo

Esethulweni sasekuseni se-AMD, u-CEO wenkampani uLisa Su ukhombise esiteji iphrosesa yezithombe ze-7nm Navi Architecture (RDNA), ezoba isisekelo somndeni wakwaRadeon RX 5700 wamakhadi evidiyo wethulwe ngoJulayi. Ukuthatha izithombe ezicacile kude kangako bekuyinkinga. , kodwa Khetha amalungu omkhakha wezindaba avunyelwe ukubamba le GPU ezandleni zawo. Maye, akubona bonke abakhathazeke kakhulu ngosayizi kangangokuthi bahlala bephethe amathuluzi okulinganisa anembayo, futhi abahloli be-AMD ngeke bakwazi ukugunyaza ukukhohlisa okunjalo ngamasampula emikhiqizo engakathulwa.

Nokho abamele indawo AnandTech Sikwazile ukuthola umbono ongemuhle wendawo yokufa ye-Navi GPU. Ngokusho kwabo, ayidluli 275 mm2. Noma sicabanga ukuthi lesi sibalo esinzima kakhulu, izinzuzo zokusebenzisa ubuchwepheshe benqubo ye-TSMC ye-7nm zisobala lapha. Njengoba kushiwo ngaphambili esethulweni, isizukulwane sokuqala sama-GPU anokwakheka kwe-RDNA sithuthukisa isilinganiso sokusebenza-kuya-amandla ngo-50% uma siqhathaniswa nesakhiwo se-GCN. Ngaphezu kwalokho, ubuchwepheshe benqubo ye-7-nm benza kube nokwenzeka ukukhiqiza i-crystal ehlangene kahle.

Esethulweni sasekuseni, i-AMD iqhathanise ikhadi lemifanekiso le-Radeon RX 5000 elinemibandela nekhadi lemifanekiso le-NVIDIA GeForce RTX 2070, futhi e-Strange Brigade, umkhiqizo onokwakheka kwe-Navi ubushesha okungenani ngo-10%. Kuze kube manje, ayikho idatha eqondile ngezindleko zamakhadi evidiyo e-AMD amasha, kodwa "anamandla okwenza amanani", ngoba iphrosesa yehluzo ye-TU106 engaphansi komkhiqizo we-NVIDIA ikhiqizwa kusetshenziswa ubuchwepheshe be-12-nm, kanye nendawo yayo yekristalu. cishe 445 mm2. Uma sikhuluma nje, i-AMD inenzuzo yendawo engama-62%.

Vele, ngaphandle kokwazi ama-nuances obudlelwano benkontileka phakathi kwe-AMD ne-NVIDIA ne-TSMC, kunzima ukuthola iziphetho ezihlukene mayelana nezindleko ze-7-nm GPUs zangaphambili kanye ne-12-nm GPUs yakamuva. Kodwa-ke, siyayikhumbula ingqungquthela yakamuva yekota ye-NVIDIA yezitatimende zokuzidla zomsunguli wenkampani, u-Jen-Hsun Huang, mayelana nokuntuleka kwesidingo sokushintshela kubuchwepheshe bokukhiqiza be-7nm. Uveze ukuthi iminikelo ekhona ye-NVIDIA ayinakuqhathaniswa ngokusebenza kanye nokusetshenziswa kwamandla, nakuba ikhiqizwa ngobuchwepheshe be-12nm, futhi akukho phuzu lokuyiqhathanisa nemikhiqizo yesimbangi engu-7nm. Ake silinde uJulayi futhi sibone ukuthi i-rhetoric yekhanda le-NVIDIA ishintsha kanjani ngemuva kokukhishwa kwezibuyekezo ezizimele zamakhadi wevidiyo we-AMD wakamuva...
