Jiya Apple ya gabatar , yana nuna sabbin na'urorin sarrafa tebur na Intel Comet Lake da GPUs na tushen AMD Navi. Gabaɗaya, an gabatar da sabbin katunan bidiyo guda huɗu na Radeon Pro 5000 tare da kwamfutocin, waɗanda za su kasance na musamman a cikin sabon iMac.
Mafi ƙanƙanta a cikin sabon jerin shine katin bidiyo na Radeon Pro 5300, wanda aka gina akan na'urar sarrafa hoto ta Navi tare da Units 20 Compute (CU) kawai kuma, saboda haka, na'urori masu sarrafa rafi 1280. Ba a ƙayyade mitar agogon GPU ba, amma ƙimar aikin mafi girma shine 4,2 Tflops (FP32). Adadin GDDR6 RAM shine 4 GB.
Ɗaya daga cikin mataki shine Radeon Pro 5500 XT, wanda ke da 8 GB na ƙwaƙwalwar ajiya da GPU tare da 24 CUs da 1536 masu sarrafa rafi. Matsayin aikinsa shine 5,3 Tflops, wanda shine 0,1 Tflops sama da mabukaci Radeon RX 5500 XT. Na gaba Radeon Pro 5700, wanda aka gina akan guntu tare da CUs 36, wato, tare da na'urori masu sarrafa rafi 2304 kuma yana da 8 GB na GDDR6. Matsayin wasan kwaikwayon anan shine teraflops 6,2, wanda yayi ƙasa da aikin Radeon RX 5700, wanda ke ba da teraflops 7,95.
A ƙarshe, sabon samfurin mafi tsufa shine katin bidiyo na Radeon Pro 5700 XT. Yana ba da na'urori masu sarrafa rafi 2560 kuma har zuwa teraflops 7,6 na aiki. Don kwatantawa, mabukaci Radeon RX 5700 XT yana da ikon isar da teraflops 9,75. A bayyane yake, irin wannan babban bambance-bambancen shine saboda gaskiyar cewa don amfani a cikin matsananciyar yanayi iMac, sabon samfurin yana da iyakancewa sosai a cikin amfani da wutar lantarki kuma, daidai da haka, a cikin mitoci. Yana da ban sha'awa cewa sabon Radeon Pro 5700 XT yana da 16 GB na ƙwaƙwalwar GDDR6 maimakon 8 GB a cikin Radeon RX 5700 XT na jama'a.
Kamar yadda kuke gani a cikin nunin faifai a sama, sabbin katunan zane suna ba da haɓaka mai mahimmanci a cikin aiki idan aka kwatanta da mafita na tushen AMD Vega waɗanda aka yi amfani da su a baya.
