AMD, da rashin alheri, kwanan nan ba zai iya yin fahariya da katunan bidiyo waɗanda za su iya yin gasa daidai da ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun fafatawa a gasa. Amma duk yana da ban sha'awa don kallon lokutan da "Reds" ke gudanar da rarrabe kansu. Misali, kamar yadda gwajin aikin katin bidiyo a cikin sabon mai harbi Yakin Duniya Z ya nuna, AMD mafita suna iya samun nasarar ficewa har ma da GeForce RTX 2080 Ti.
Yaƙin Duniya na Z daga Saber Interactive wasa ne da aka inganta don katunan zane na AMD, wanda kuma yana amfani da Vulkan API. Kuma kamar yadda kuka sani, wannan API ɗin ya aro da yawa daga Mantle, API ɗin da AMD kanta ta ƙirƙira. Don haka ba abin mamaki bane cewa katunan zane na Radeon suna aiki da kyau a cikin wannan sabon wasan. Anan ina so in tunatar da ku cewa a cikin Doom guda ɗaya dangane da Vulkan, katunan bidiyo na AMD kuma sun nuna sakamako mai kyau.
Gwajin katunan bidiyo a yakin duniya na Z an gudanar da shi ta hanyar GameGPU albarkatun. Bencin gwajin ya dogara ne akan na'ura mai sarrafa Core i9-9900K wanda aka rufe shi zuwa 5,2 GHz, wanda kusan yana kawar da tasirin mai sarrafawa akan sakamakon. Kuma suna, a gaskiya, kawai ban mamaki.
A cikin mafi kyawun ƙudurin Cikakken HD na yau (pixels 1920 × 1080), mafi kyawun aikin Radeon VII ya nuna, Radeon RX Vega 64 Liquid Cooled (siffa tare da daidaitaccen tsarin sanyaya ruwa) da daidaitaccen sigar Radeon RX Vega 64. The katin bidiyo na NVIDIA GeForce RTX 2080 Ti yana samuwa ne kawai a wuri na hudu, yana yin hasara sosai ga masu fafatawa. Ina kuma so in lura cewa Radeon RX Vega 56 ya sami damar wuce GeForce GTX 1080 Ti da RTX 2080.
A mafi girman ƙudurin Quad HD (pixels 2560 × 1440), ma'aunin iko a cikin babban ɓangaren zane ya kasance kusan ba canzawa, amma bambanci tsakanin katunan bidiyo na AMD da NVIDIA ba su da girma sosai. Dangane da matsakaicin ƙimar firam, GeForce RTX 2080 Ti ya ɗan gaban Radeon RX Vega 64, amma ya ɓace dangane da mafi ƙarancin mitar.
A ƙarshe, a cikin ƙudurin 4K (pixels 3840 × 2160), flagship ɗin NVIDIA ya sami nasarar ɗaukar wuri na farko tare da gefen FPS da yawa. Hakanan yana da mahimmanci a lura cewa Radeon VII da Radeon RX Vega 64 Liquid Cooled katunan bidiyo sun nuna sakamako iri ɗaya. Amma mashahurin Radeon RX 580 ya ragu zuwa matakin GeForce GTX 1070 Ti.
Baya ga fitattun sakamako, yana da mahimmanci a lura cewa katunan bidiyo na AMD suna da rahusa sosai fiye da tutocin NVIDIA. Misali, Radeon RX Vega 64, wanda ya sami damar fin karfin GeForce RTX 2080 Ti, kusan sau uku kasa da katin bidiyo na “kore”. Halin ya yi kama da sauran AMD da NVIDIA accelerators.
Gabaɗaya, wannan babban demo ne wanda ke nuna abin da ƙarancin matakin API ɗin da aka aiwatar da kyau zai iya yi. Abin tausayi kawai shi ne cewa wannan da wuya ya faru a yanayin katunan bidiyo na AMD. Bugu da ƙari, misali na Yaƙin Duniya na Z ya nuna cewa daga ra'ayi na aikin "bare", katunan bidiyo na AMD suna da ikon yin gasa tare da mafita na abokin adawar su, amma ɓangaren software ya hana su.
