So, it would appear that rumors and leaks about the RX 500 series being simple rebrands of AMD's RX 400 line were true. Recent leaks point to no more changes and performance increases than those achieved through higher base clock speeds on the graphics cards' GPU and memory. The architecture is the same, and the process seems to have followed the same path - as of yet, no confirmation regarding whether or not these cards do use a newer, leaner LPP process for higher clocks and less power consumption.The RX 580 will come in with clocks at 1340 MHz with 4 GB and 8 GB GDDR5 variants clocking in at 8.0 GHz along a 256-bit bus interface. This amounts to 256 GB/s of bandwidth, and pricing should be around the $199 - $249 mark. On the leaked Firestrike Extreme test, this card was clocked to 1500 MHz (not easy to achieve with current Polaris 10 GPUs) and a 6675 points score. The RX 570, on the other hand, seems to have not been given the core clocks bump treatment, but memory speeds should see an increase to 7 GHz, delivering 224 GB/s of bandwidth. Overclocked to 1325 MHz, it delivered a score of 5719 points in the same benchmark. Finally, the new kid on the block, AMD's Polaris 12 is somewhat of a head-scratcher of a part, with its measly 640 stream processors (the line between discrete graphics and integrated ones is really blurry here). RX 550 reference cards should come in at 1190 MHz, where it scores 1849 in 3DMark FireStrike Extreme, though the card does so with only PCIe power.Pricing should be in line with AMD's RX 400 series, and performance should be comparable to RX 400 AIB cards, so no setting the world on fire here. If delay reports are true, expect these to be launched on April 18th. The RX 560 is MIA for now, but there is no reason to think it won't be launched alongside the other cards in the RX 500 line.
