Izolo kwethulwe i-Apple , equkethe amaphrosesa akamuva edeskithophu ye-Intel Comet Lake nama-GPU asuselwa ku-AMD Navi. Sekukonke, amakhadi wevidiyo ama-Radeon Pro 5000 amasha ethulwa kanye namakhompyutha, azotholakala kuphela ku-iMac entsha.
Omncane kunabo bonke ochungechungeni olusha ikhadi levidiyo le-Radeon Pro 5300, elakhelwe phezu kwephrosesa yezithombe ze-Navi enamayunithi angama-20 kuphela eCompute (CU) futhi, ngokufanele, ama-processor okusakaza ayi-1280. Imvamisa yewashi le-GPU ayicacisiwe, kodwa inani eliphakeme lokusebenza ngu-4,2 Tflops (FP32). Inani le-GDDR6 RAM ngu-4 GB.
Isinyathelo esisodwa i-Radeon Pro 5500 XT, enenkumbulo engu-8 GB kanye ne-GPU enama-24 CUs namaphrosesa angu-1536 okusakaza. Izinga layo lokusebenza ngu-5,3 Tflops, okuyi-0,1 Tflops ephakeme kunomthengi i-Radeon RX 5500 XT. Okulandelayo kuza i-Radeon Pro 5700, eyakhelwe ku-chip enama-36 CUs, okungukuthi, enamaphrosesa angu-2304 okusakaza futhi ano-8 GB we-GDDR6. Izinga lokusebenza lapha ngama-teraflops angu-6,2, eliphansi kakhulu kunokusebenza kwe-Radeon RX 5700, enikeza ama-teraflops angu-7,95.
Ekugcineni, umkhiqizo omusha omdala kwakuyikhadi levidiyo leRadeon Pro 5700 XT. Inikeza ama-processor wokusakaza angu-2560 kanye nokusebenza okungafika kokungu-7,6 kwama-teraflops. Uma kuqhathaniswa, umthengi iRadeon RX 5700 XT iyakwazi ukuletha ama-teraflops angu-9,75. Ngokusobala, umehluko omkhulu kangaka ungenxa yokuthi ukusetshenziswa ezimeni eziminyene iMac, umkhiqizo omusha unomkhawulo kakhulu ekusetshenzisweni kwamandla futhi, ngokufanele, ngamaza. Kuyathakazelisa ukuthi iRadeon Pro 5700 XT entsha inememori engu-16 GB ye-GDDR6 esikhundleni sika-8 GB kuRadeon RX 5700 XT etholakala esidlangalaleni.
Njengoba ubona kumaslayidi ngenhla, amakhadi amasha ezithombe anikeza ukuthuthukiswa okuphawulekayo ekusebenzeni uma kuqhathaniswa nezixazululo ezisekelwe ku-AMD Vega ezazisetshenziswa ngaphambili.
