A yau a buɗe Computex 2019, AMD ta samfoti da dangin Navi da aka daɗe ana jira na katunan bidiyo na caca. Jerin sabbin samfuran sun sami sunan tallan Radeon RX 5000.
Yana da kyau a tuna cewa tambayar ya kasance ɗayan manyan abubuwan ban sha'awa lokacin gabatar da zaɓuɓɓukan wasan Navi. Kodayake da farko an ɗauka cewa AMD za ta yi amfani da fihirisar lambobi daga jerin 5000, kamfanin a ƙarshe ya zaɓi sunan Radeon RX 50. Manufar da ke bayan sunan ita ce tana wasa akan taken bikin cika shekaru XNUMX da AMD ke bikin wannan shekara. .
Bugu da ƙari, an bayyana wani dalla-dalla mai ban sha'awa. Katunan bidiyo na Radeon RX 5000 sun dogara ne akan sabon tsarin gine-gine na GPU da ake kira Radeon DNA (RDNA), wanda shine ƙarin haɓaka na Graphics Core Next (GCN) wanda ya bayyana shekaru bakwai da suka gabata.
Gine-gine na RDNA ya bayyana yana ba da sabon ƙira don ainihin rukunin GPU, naúrar ƙididdigewa, yana haifar da haɓaka ƙarfin ƙarfin aiki da aiki kowane agogo. Bugu da kari, AMD ta aiwatar da sabon matsayi na cache a cikin RDNA, wanda yakamata ya rage jinkiri, haɓaka kayan aiki, da haɓaka amfani da wutar lantarki. Ingantaccen bututun zane na RDNA kuma yana ba da damar sabbin katunan zane suyi aiki a cikin saurin agogo fiye da da, yana haifar da matakan aiki mafi girma. Bugu da kari, idan aka kwatanta da kwakwalwan kwamfuta tare da gine-ginen GCN, Navi yana da ƙaramin guntun guntu na semiconductor, amma har yanzu masana'anta bai bayyana cikakkun bayanai ta nawa ba.
Gabaɗaya, tsarin gine-gine na RDNA yana ba da mafi girman aiki da ƙarancin jinkiri tare da ingantaccen farashi. Idan aka kwatanta da tsarin gine-gine na katin Vega, AMD ta yi alƙawarin haɓaka kashi 25 cikin ƙayyadaddun ayyuka a kowane agogo da haɓaka 50 bisa ɗari a takamaiman aikin kowace watt.
Kamar yadda aka sanar a gabatarwar, wurin farko na aikace-aikacen sabon gine-gine na RDNA zai kasance jerin katunan zane na Radeon RX 5000, inda za a fitar da katunan bidiyo na farko da ake kira Radeon RX 5700. Dukkanin jerin za su dogara ne akan guntun Navi. , samar ta amfani da fasahar tsari na 7-nm a wuraren TSMC.
Wani muhimmin fasali na jerin Radeon RX 5000 zai zama goyon bayansu ga bas ɗin PCI Express 4.0. AMD yana haɓaka ra'ayin motsawa zuwa sabon juzu'in dubawa tare da haɓaka bandwidth, kuma Radeon RX 5000 zai dace daidai da yanayin yanayin kamfanin tare da na'urori na Ryzen na ƙarni na uku da motherboards dangane da chipset X570.
A cikin jawabinta, Shugabar AMD Lisa Su a taƙaice ta nuna aikin katin bidiyo na caca dangane da guntu Navi. An kwatanta katin zane na Radeon RX 5700 da NVIDIA GeForce RTX 2070 a cikin ma'auni na Brigade mai ban mamaki. A lokaci guda, sabon samfurin AMD da ake tsammanin ya juya ya zama kusan 10% cikin sauri.
AMD na da niyyar fara siyar da katunan bidiyo na Radeon RX 5700 a watan Yuli, amma har yanzu ba a sanar da takamaiman kwanan wata ba. Koyaya, AMD tayi alƙawarin bayyana ƙarin bayani game da ƙayyadaddun ƙayyadaddun bayanai, farashi, da aikin Navi a taron Wasannin Wasannin Horizon na gaba a E3 akan Yuni 10, 2019.
