There was an interesting listing of a desktop variant of the AMD Radeon RX 5300 XT graphics card in the spec sheet of an upcoming HP Pavilion desktop PC (model TP01-0004ng). The listing shows that the RX 5300 XT has 4 GB of GDDR5 memory. This is the first time we’ve seen the desktop RX 5300 XT in the wild. It is suggested that the RX 5300 XT will have a higher CU count than the RX 5300 (non-XT), but will have cheaper GDDR5 memory compared to the RX 5500-series.
Both the RX 5300-series and RX 5500-series will be based on the 7 nm “Navi 14” silicon which will feature up to 24 RDNA compute units (1,536 stream processors) and a 128-bit wide memory interface for either GDDR6 or GDDR5 memory. It is expected that AMD will phase out 14 nm and 12 nm “Polaris 10” and “Polaris 30” chips with “Navi 14”.
