Sapphire debuted its Radeon RX 590 series last month with the RX 590 Nitro+ Special Edition, which at the time was advertised as a limited-edition SKU. The company over Holiday weekend updated its product stack to introduce a new mass-production SKU, the RX 590 Nitro+ OC, minus “Special Edition” branding. There are only cosmetic changes between the two SKUs. Sapphire’s favorite shade of blue on the Special Edition SKU makes way for matte-black on the cooler shroud, as do the black accents on the back-plate, instead of blue. The fan impellers are opaque matte black instead of frosty and translucent.
Thankfully, Sapphire hasn’t changed the specs that matter – factory-overclock. The card still ships with 1560 MHz engine clocks (boost), and 8.40 GHz (GDDR5-effective) memory, and a “quiet” second BIOS that dials down the clocks to 1545 MHz boost and 8.00 GHz memory. The underlying PCB is unchanged, too, drawing power from a combination of 8-pin and 6-pin PCIe power connectors, and conditioning it with a 6+1 phase VRM. Display outputs include two each of DisplayPort 1.4 and HDMI 2.0, and a dual-link DVI-D. The company didn’t reveal pricing, although we expect it to be marginally lower than the Special Edition SKU.
