Spotted by Videocardz.com, the XFX RX 460 uses a slim single-slot cooler with a 70mm fan which should keep the smaller Polaris 11 GPU well cooled. It uses a red and black color scheme on the shroud and features DVI, HDMI 2.0b and DisplayPort 1.4 outputs.
The new XFX RX 460 Core Edition will be available in 2GB and 4GB GDDR5 versions. Both versions are sticking to AMD reference clocks, 1090MHz GPU base, 1220MHz GPU Boost while 128-bit interface memory ended up clocked at 7.0GHz. As this is a Radeon RX 460 graphics card, it does not need an additional PCIe power connector, drawing enough power from the PCIe slot to satisfy its 75W TDP.
Bear in mind that XFX is also the only AMD AIB partner that offers a passive cooler Radeon RX 460, although with a large 2-slot heatsink.
Unfortunately, there is no information on the price or the availability date for the new single-slot XFX RX 460 Core Edition.
