AMD decided to change things up on the RX 560. It will actually have more Stream Processors than its previous counterpart. It will have 1024 stream processors over the RX 460’s 896. This means you’ll also get a TMU increase from 56 to 64, though the ROP count is the same. The RX 560 will have a boost clock of 1257, that is 57 over the RX 460’s 1200 MHz. The card will have memory configurations up to 4GB. And then finally we have the new RX 550. It has 512 Stream processors (8 CUs) and is clocked at 1183 MHz boost. The card will make use of 2GB of memory.
