Lero pakutsegulira kwa Computex 2019, AMD idawoneratu banja lake la Navi lomwe likuyembekezeredwa kwanthawi yayitali lamakhadi amasewera. Zatsopano zatsopano zidalandira dzina lazamalonda Radeon RX 5000.
M'pofunika kukumbukira kuti funso chinali chimodzi mwazosangalatsa kwambiri poyambitsa masewera a Navi. Ngakhale poyamba zinkaganiziridwa kuti AMD idzagwiritsa ntchito zizindikiro zowerengera kuchokera ku 5000-series, kampaniyo pamapeto pake inasankha dzina lakuti Radeon RX 50. Lingaliro la dzinali ndiloti limasewera pamutu wa zaka XNUMX zomwe AMD ikukondwerera chaka chino. .
Kuphatikiza apo, tsatanetsatane wina wochititsa chidwi adawululidwa. Makhadi amakanema a Radeon RX 5000 amachokera ku kamangidwe katsopano ka GPU kotchedwa Radeon DNA (RDNA), komwe ndi chitukuko china cha Graphics Core Next (GCN) chomwe chinawonekera zaka zisanu ndi ziwiri zapitazo.
Zomangamanga za RDNA zikuwoneka kuti zikupereka mapangidwe atsopano a gawo lalikulu la GPU, gawo la compute, zomwe zimapangitsa kuti mphamvu zitheke komanso magwiridwe antchito pa wotchi iliyonse. Kuphatikiza apo, AMD yakhazikitsa dongosolo latsopano la cache mu RDNA, lomwe liyenera kuchepetsa kuchedwa, kuchulukitsa kutulutsa, komanso kuwongolera kugwiritsa ntchito mphamvu. Mapaipi azithunzi a RDNA okongoletsedwa amalolanso makhadi atsopanowa kuti azigwira ntchito mothamanga kwambiri kuposa kale, zomwe zimapangitsa kuti magwiridwe antchito azikhala apamwamba. Kuphatikiza apo, poyerekeza ndi tchipisi tokhala ndi kamangidwe ka GCN, Navi ili ndi chip chophatikizika kwambiri cha semiconductor, koma mpaka pano wopanga sanaulule zambiri ndi kuchuluka kwake.
Ponseponse, kapangidwe ka RDNA kamapereka magwiridwe antchito apamwamba komanso kutsika kotsika komanso kutsika mtengo kwabwinoko. Poyerekeza ndi kamangidwe ka makhadi a Vega, AMD idalonjeza kuwonjezeka kwa 25 peresenti ya magwiridwe antchito pa wotchi iliyonse komanso kuwonjezeka kwa 50 peresenti ya magwiridwe antchito pa watt iliyonse.
Monga momwe adalengezedwera pawonetsero, mfundo yoyamba yogwiritsira ntchito zomangamanga zatsopano za RDNA idzakhala makadi ojambula a Radeon RX 5000, momwe makadi oyambirira a kanema otchedwa Radeon RX 5700 adzatulutsidwa. Mndandanda wonsewo udzakhazikitsidwa ndi Navi chips. , yopangidwa pogwiritsa ntchito ukadaulo wa 7-nm m'malo a TSMC.
Chochititsa chidwi kwambiri pa mndandanda wa Radeon RX 5000 chidzakhala chithandizo chawo pa basi ya PCI Express 4.0. AMD ikulimbikitsa kwambiri lingaliro losamukira ku mtundu watsopano wa mawonekedwe omwe ali ndi bandwidth yowonjezereka, ndipo Radeon RX 5000 idzakwanira bwino mu chilengedwe cha kampaniyo pamodzi ndi mapurosesa a Ryzen a m'badwo wachitatu ndi ma boardboards otengera X570 chipset.
M'mawu ake, CEO wa AMD, Lisa Su, adawonetsa mwachidule magwiridwe antchito a vidiyo yamasewera yozikidwa pa Navi chip. Khadi la zithunzi za Radeon RX 5700 linafanizidwa ndi NVIDIA GeForce RTX 2070 mu benchmark ya Strange Brigade. Nthawi yomweyo, zomwe zimayembekezeredwa zatsopano za AMD zidakhala pafupifupi 10% mwachangu.
AMD ikufuna kuyamba kugulitsa makadi a kanema a Radeon RX 5700 mu Julayi, koma tsiku lenileni silinalengezedwe. Komabe, AMD yalonjeza kuti iwulula zambiri za Navi's specs, mitengo, ndi magwiridwe ake pa Next Horizon Gaming chochitika pa E3 pa June 10, 2019.
