A wajen gabatar da safiya na AMD, Shugabar kamfanin Lisa Su ta nuna daga mataki na'urar sarrafa hoto na 7nm Navi architecture (RDNA), wanda zai zama tushen dangin Radeon RX 5700 na katunan bidiyo da aka gabatar a watan Yuli. Ɗaukar bayyanannun hotuna a irin wannan nesa yana da matsala. , amma An ba da izinin Zaɓin membobin ƴan jarida su riƙe wannan GPU a hannunsu. Alas, ba duka ba ne ke damuwa game da girman da koyaushe suke ɗaukar ma'aunin daidaitattun kayan aiki tare da su, kuma masu binciken AMD ba za su iya amincewa da irin wannan magudi tare da samfuran samfuran da ba a gabatar da su ba tukuna.
Kuma duk da haka wakilan shafin Mun sami damar samun cikakken ra'ayi game da yankin mutu na Navi GPU. A cewar su, bai wuce 275 mm2 ba. Ko da mun yi la'akari da cewa wannan ƙididdiga ce mai tsauri, fa'idodin amfani da fasaha na 7nm na TSMC a bayyane yake a nan. Kamar yadda aka bayyana a baya a cikin gabatarwar, ƙarni na farko na GPUs tare da gine-ginen RDNA yana haɓaka ƙimar aiki-zuwa-ƙarfi da 50% idan aka kwatanta da gine-ginen GCN. Bugu da ƙari, fasahar tsari na 7-nm yana ba da damar samar da kristal mai mahimmanci.
A gabatarwar safiya, AMD ta kwatanta katin zane na Radeon RX 5000 na sharaɗi tare da katin zane na NVIDIA GeForce RTX 2070, kuma a cikin Brigade mai ban mamaki, samfurin tare da gine-ginen Navi ya kasance aƙalla 10% cikin sauri. Ya zuwa yanzu, babu takamaiman bayanai game da farashin sabbin katunan bidiyo na AMD, amma suna da ƙarin “tashi don sarrafa farashin”, saboda TU106 na'ura mai sarrafa kayan aikin da ke ƙasan samfurin NVIDIA an samar da shi ta amfani da fasaha na 12-nm, da yanki na crystal. shi ne kusan 445 mm2. Kusan magana, AMD yana da fa'idar yanki 62%.
Tabbas, ba tare da sanin ma'anar dangantakar kwangila tsakanin AMD da NVIDIA tare da TSMC ba, yana da wahala a zana ra'ayi mai mahimmanci game da farashin 7-nm GPUs na tsohon da 12-nm GPUs na ƙarshen. Koyaya, muna tunawa da taron NVIDIA na kwata kwata na kwanan nan don maganganun girman kai na wanda ya kafa kamfanin, Jen-Hsun Huang, game da rashin buƙatar canzawa zuwa fasahar samar da 7nm. Ya bayyana cewa, kyautar da NVIDIA ke bayarwa ba ta misaltuwa ta fuskar aiki da kuma amfani da wutar lantarki, duk da cewa ana samar da su ta hanyar fasahar 12nm, kuma babu wata fa'ida idan aka kwatanta su da kayayyakin 7nm na masu gasa. Bari mu jira Yuli mu ga yadda maganganun shugaban NVIDIA ke canzawa bayan sakin sake dubawa masu zaman kansu na sabbin katunan bidiyo na AMD…
