Graphics card makers haven't been releasing their various Radeon RX 500 series cards in any particular order, but it somehow seems fitting that we get to XFX after seeing fresh cards from Asus, Gigabyte, MSI, PowerColor, and Sapphire in the last few days. Zotac is a Nvidia-only house, so XFX is probably the last card in AMD's board partner Rolodex. PowerColor rolled out six different Radeon RX 570 and 580 cards, Sapphire will burden shelves with nine models, and XFX is firing both barrels with an even dozen of different takes on the Polaris 20 theme.
Out of that dozen varieties, only two of the cards are Radeon RX 570 models, both dubbed Radeon RX 570 RS 4GB XXX Edition. Your humble author was unable to tease out any meaningful difference between the two models. Both have the same 4 GB of 7 GT/s GDDR5 memory funneling bits into identically-clocked cores. When in OC mode, these cards will boost the RAM speed up to 7.1 Gbps.
XFX is offering an eye-glazing ten different Radeon RX 580 models. Of these, two are 4 GB models packing the same 7 GT/s GDDR5 memory found in the company's RX 570 offerings, along with core clock speeds that stick pretty close to AMD's reference specifications. This leaves eight different varieties of 8 GB RX 580 cards, all packing 8 GT/s GDDR5 memory and differing subtly in core clock speeds and cooler design. The GTS-marked models are bestowed with the cooler pictured just above this paragraph, while GTR and GTR-S cards get the larger cooler shown below.
The two GTR models are apparently exclusive to Best Buy, but the range-topping, tongue-twisting Radeon RX 580 GTR-S Black Edition Crimson variants and their 1430 MHz "True Clock" are fortunately available wherever XFX cards are sold.
All twelve cards sport three DisplayPort jacks, one HDMI port, and one DVI-D connector. The XFX Radeon RX 570 RS 4GB XXX is available now for $190, and the hot-clocked Radeon GTR-S is available for $280.
