With the launch of the Radeon RX 500-series cards, Gigabyte's ready to go with a bundle of new Radeons. The company is launching four cards under its Aorus brand and three more boards under its own nameplate.
Starting at the top, we have the Aorus Radeon RX 580 XTR 8G. Predictably, this card comes with 8GB of GDDR5 memory running at 8 GT/s. It uses a quad-heatpipe cooler equipped with dual 100-mm fans to keep AMD's Polaris 20 GPU cool. Clock rates can go as far as 1439 MHz in OC mode or 1425 MHz in gaming mode. Users are welcome to do their own overclocking, and Gigabyte says this XTR model has reinforced power delivery hardware to help in that endeavor.
Gigabyte is also offering Aorus cards without the "XTR" marking. You can purchase one with either 4GB or 8GB of memory, although the 4GB model also takes a 1 GT/s hit to its memory transfer rate (down to 7 GT/s). These cards use a fairly similar cooler to their top-tier XTR cousin, but with smaller fans and without the RGB LED accents on the front. They also run lower GPU clock rates, boosting to "only" 1380 MHz in OC mode or 1365 MHz in gaming mode.
Folks who don't mind stepping down from the top can purchase an Aorus Radeon RX 570 card. This model is only available with 4GB of memory, and it runs its slightly-pared Polaris 20 GPU at 1295 MHz in OC mode or 1280 MHz in gaming mode. Besides those changes, this version appears to be identical to the non-XTR RX 580 cards above.
Finally, the company is launching a trio of cards for traditionalists who prefer the Gigabyte name. The Radeon RX 580 Gaming comes in versions with 8GB and 4GB of memory. These two cards appear to be twins, running their fully-enabled Polaris 20 GPUs at 1355 MHz in OC mode or the reference 1340 MHz otherwise. There's also an RX 570 Gaming card with 4GB of memory onboard that runs at 1255 MHz in OC mode.
All of Gigabyte's new Radeons come with three DisplayPort connectors, an HDMI port, and a dual-link DVI-D connector. They also all rely on a single eight-pin power connector for their juice.
Newegg has all seven cards in stock right now. The fanciest card here, the Aorus RX 580 XTR, will set you back $260. Stepping down the stack, you can pick up an Aorus RX 580 8G for $230 or its Gigabyte-branded equivalent for $220. The 4GB RX 580 cards are $200 for either model. Finally, the RX 570 cards run $180 for the Aorus card and $170 for the Gigabyte version.
