As reported earlier, AMD is prepping to launch a new product line based on the RDNA 1 architecture for miners. Thanks to info obtained by ITHome, we now know the names of these graphics cards. The mining GPUs will have the following naming: Radeon RX 5500 XTB, Radeon RX 5600 XTB, Radeon RX 5700 XTB, where B stands for blockchain.
While the RX 5700 XT would make for a capable Ether mining GPU with a hash rate between 54-56 MH/s, roughly the same as the RTX 3070 and the RX 6800 XT, the Navi 12-based RX 5500 XT is limited to a 128-bit bus and a bandwidth of just 224GB/s.
Furthermore, the 4GB variant will not worth be able to miner Ether in most cases due to the algorithm DAG size being 4.117GB. Even if it does with a multi-algorithm protocol, the returns will be pretty low. Other currencies like KAWPAW should be compatible but that will net you just a dollar worth of profit for an entire day of mining.
The RX 5700 XT is another story altogether. With a bandwidth same as that of the RTX 3070 and the RX 6800 XT, it can manage a respectable 54-55 MH/s which can amount to profits of nearly $5/day per GPU. With a memory overclock, you can extract up to $6-6.5 from the card with little to no increase in power.
As for the RX 5600 XT, it is capable of delivering a hash rate of nearly 40 MH/s which results in a daily profit of $5 per card, and a monthly revenue of over $100 per GPU.

NVIDIA’s CMP 50X miner has an Ether hash rate of 45 MH/s, around 15-20% lower than the RX 5700 XT (full-fledged Navi 10). Only the 90X which is based on the newer GA102 (Ampere) die offers a higher hash rate of 86 MH/s.
