Although the Radeon RX 5300 features the same amount of stream processors as the RX 5500 XT, 1,408 to be precise, the memory interface has been cut down to 96-bit, and it comes with 3GB of 14Gbps GDDR6 memory, leaving it with a total memory bandwidth of 168GB/s. The GPU is clocked at up to 1,645MHz.
Bear in mind that it also has 32 ROPs, just like the RX 5500 XT and a 100W TDP, which makes it a rather interesting discrete graphics card, although it will need at least a single 6-pin PCIe power connector.
Unfortunately, it is still not clear if this is an OEM exclusive graphics card or it will come to retail/e-tail shelves, so we do not have the precise price or the availability date.
