It seems there could be a short delay in the launch of AMD’s first 500-series cards. Note that this new development is still speculative and can be traced back to a report by MyDrivers.
According to the said report, the Radeon RX 570 and RX 580 graphics cards are unlikely to mark their debut anytime before April 18.
As you know, both these cards are powered by the Polaris 10 GPU and they come with by and large the same specs as the Radeon RX 480 and RX 470 cards. The only major difference would be the clock speeds which is expectedly higher in the new cards. So, overall there won’t be any drastic changes or improvements on the table when it comes to IPC improvements and/or architecture design.
There are, however, reports that a matured process can help the RX 570 and RX 580 cards deliver a significantly higher power efficiency.
Note that along with the Polaris 10-based rebrands, AMD is also going to introduce rebranded Polaris 11 cards as members of the RX 500 family. Not just that, speculations are rife regarding a smaller Polaris 12 core too. If true, the Polaris 12 product might throw some serious challenge in the way of NVIDIA’s GeForce GTX 1050 (although, we would still bet our money on the GTX 1050).
AMD Radeon RX 580 specs
For the uninitiated, the AMD Radeon RX 580 will probably sport a higher clocked Polaris 10 GPU, meaning it will be somewhat similar to many custom variants of the RX 480 already available in the market. Other key specs include 2304 stream processors, 32 ROPs, 144 TMUs. The chip will be clocked at 1340 MHz boost and it will deliver up to 6.17 TFLOPs of compute performance. The 8GB GDDR5 memory is clocked at 8 GHz along the 256-bit bus interface.
With an expected output of 256 Gbps, the 8GB variant of the AMD Radeon RX 480 will probably retail at somewhere around $199.
AMD Radeon RX 570 specs
The second of the new Polaris 10 powered cards, the Radeon RX 570, is expected to bear a lot of similarity with the Radeon RX 470. It will sport a cutdown Polaris core featuring 2048 cores. It boasts 1244 MHz boost that could deliver an output of as much as 5.10 TFLOPs.
The RX 570 is expected to bring 8GB of GDDR5 clocked at 7.0 GHz, enabling it to yield an output of 224 Gbps. As for the price, the Radeon RX 570 will set you back $149 or so.
