Ukulungela kwe-AMD ukwethula umndeni wakwaRadeon RX 5500 wamakhadi evidiyo ngo-Okthoba 14 kwaziwa muva nje, kodwa isisekelo esingaba khona semikhiqizo emisha ngesimo se-Navi 7 graphic processor kuxoxwe ngaso isikhathi eside kakhulu. Manje singasho ngokuqiniseka ukuthi iphrosesa yehluzo izokhiqizwa kusetshenziswa ubuchwepheshe be-158nm futhi izogxila ku-2 billion transistors endaweni engu-6,4 mm1408. Inamaphrosesa angu-1845 wokusakaza namafrikhwensi afika ku-XNUMX MHz, kuye ngemodi yokusebenza.
Umkhiqizo omusha uhlukile ngoba okokuqala ngqa esigabeni senani elingabizi kakhulu unikeza inkumbulo ye-GDDR6 yemikhiqizo ye-AMD nokusekelwa kwesixhumi esibonakalayo se-PCI Express 4.0. Kunqunywe ukushiya ibhasi 128-bit, kodwa abazange badele imvamisa yenkumbulo, ngakho-ke isivinini sokudlulisa ulwazi esisebenzayo singafinyelela ku-14 Gbit/s. Kuyaziwa ukuthi amakhadi ezithombe zedeskithophu ochungechungeni lwe-Radeon RX 5500 angahlonyiswa ngamagigabhayithi amane noma ayisishiyagalombili enkumbulo ye-GDDR6.
Izinto zokwethula i-AMD ziqhathanisa i-Radeon RX 5500 ngokusebenza ne-Radeon RX 480 kanye ne-GeForce GTX 1650; inzuzo ephawulekayo, ngokubikezelwa, isohlangothini lomkhiqizo omusha. Umkhiqizo wemifanekiso ephathwayo obizwa nge-βRadeon RX 5500Mβ enamagigabhayithi amane enkumbulo ye-GDDR6 nawo uzonikezwa, kodwa izinguqulo zereferensi zozakwabo bedeskithophu cishe ngeke zinikezwe, nakuba ngezinjongo zemifanekiso okuthile okufanayo kuboniswa emthonjeni wangempela. Isixazululo seselula se-Radeon RX 5500M sizofakelwa inkumbulo engu-4 GB kuphela, imvamisa ephezulu ye-GPU ngeke idlule ku-1645 MHz.
Njengoba ubungalindela, isethulo asiphelelanga ngaphandle kokukhombisa izinzuzo zobuchwepheshe obusha benqubo ye-7-nm. Indawo yekristalu ye-Radeon RX 5500 GPU ayidluli ku-158 mm2, kuyilapho ine-6,4 billion transistors. Iqhathanisa umkhiqizo omusha ne-Radeon RX 480, i-AMD ikhuluma ngokwenyuka kokusebenza okuthile ngo-70% endaweni yeyunithi ngayinye yekristalu.
Inzuzo emaphakathi ye-Radeon RX 5500 ngaphezu kwe-GeForce GTX 1650 emidlalweni ingafinyelela ku-37% ekuxazululweni kwe-1080p; i-Radeon RX 5500M yeselula inenzuzo ngaphezu kwembangi yayo enguqulweni yeselula ye-GeForce GTX 1650 ingafinyelela ku-30%. Amakhadi evidiyo e-Radeon RX 5500 kanye ne-Radeon RX 5500M azovela njengengxenye yamakhompiyutha aqediwe namalaptop ngaphambi kokuphela kwale kota, kodwa ukukhishwa kwabezindaba kusho kancane mayelana nokutholakala kwezitolo. Lokhu kuchaza ukushoda kolwazi mayelana nezintengo zemikhiqizo emisha amahora ambalwa ngaphambi kwesimemezelo esisemthethweni.
I-AMD ingaba nethuba lokudlala ezimpini zamanani ne-NVIDIA, eyethula namakhadi amasha evidiyo kule nyanga, kodwa okwamanje kubonakala sengathi imfihlakalo ezungeze isimemezelo se-Radeon RX 5500 ibangelwa ukugxila komkhiqizo ikakhulukazi engxenyeni ye-OEM. . Kodwa-ke, ukukhishwa kwabezindaba kwe-AMD kuthi amakhadi wevidiyo e-Radeon RX 5500 enziwe abalingani benkampani azokhululwa ngaphambi kokuphela kwekota, ngakho-ke kunengqondo ukulindela ukuthi avele ezitolo.
