HIS Radeon RX 590 IceQ X² Detailed

We’re starting to see some Radeon RX 590’s on the market … just in time for Christmas 🙂

With a little Javascript trickery, Redditor “BadReIigion” succeeded in making the company website of AMD partner HIS to spit out details of its upcoming Radeon RX 590 IceQ X² graphics card (model number: HIS-590R8LCBR). Pictured below is the RX 580 IceQ X², but we expect the RX 590-based product to be mostly similar, with cosmetic changes such as a different cooler shroud or back-plate design. The website confirms some details like the ASIC being “Polaris 30 XT,” a rendition of the 2,304-SP “Polaris 20” die on the 12 nm FinFET node, and that the card features 8 GB of GDDR5 memory. Some of the other details, such as the engine clock being mentioned as “2000 MHz” is unlikely. 

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.
