We’re starting to see some Radeon RX 590’s on the market … just in time for Christmas 🙂
The consensus emerging on engine clock boost frequencies from RX 590 leaks so far, put RX 590 custom-design, factory-overclocked cards to tick around 1500-1550 MHz, a 100-200 MHz improvement over the RX 580. Some board vendors such as Sapphire are even overclocking the memory by about 5%. “Polaris 30” is likely pin-compatible with “Polaris 20,” because most board vendors are reusing their RX 580 PCBs, some of which are even carried over from the RX 480. For the HIS RX 590 IceQ X² this means drawing power from a single 8-pin PCIe power connector.
