It has taken a bit, but we are starting to see more custom Radeon RX Vega graphics cards emerge. One of the newest is from Gigabtye. The company has officially launched its Radeon RX Vega 64 Gaming OC 8G, which as the model name suggests is an overclocked variant of the Radeon RX Vega 64, with 8GB of second generation high bandwidth memory (HBM2). It also boasts Gigabyte's custom Windforce 2X cooling solution.
Out of the box, Gigabyte's card sports a 1,276MHz base clock and 1,560MHz boost clock. AMD's reference blueprint calls for a 1,247MHz base clock and 1,546MHz boost clock, so Gigabyte did not go too crazy here. Users who want to take matters into their hands should be able to squeeze some additional performance out of this card. Obviously your mileage will vary, though Gigabyte claims this card is built for "extreme overclocking," partially because of its 12+1 power phase design for stable power delivery.
The Windforce 2X cooling solution consists of two 100mm fans with "unique fan blades" with 3D striped curves (grooves, basically) carved into them, and triangle edges. According to Gigabyte, these special blades enhance air flow by 23 percent compared to traditional fans. They also spin in opposite directions from one another to reduce turbulence, at least when engaged—the fans stay off (and thus are silent) during idle and light loads.
Underneath the fans are a pair of angular-finned aluminum blocks that extend the length of the card. Pure copper heatpipes snake through the heatsinks and flatten out to make direct contact with the GPU. This has become fairly common on coolers—both for GPUs and CPUs—that utilize copper heatpipes.
Finally, a blackplate provides additional cooling, complete with a heatpipe of its own.
"Excessive heat from GPU not only gets dissipated utilizing the massive cooling module in the front but also through the back side with a copper plate, providing a well-rounded thermal solution for the GPU. And additional heatpipe on the back can dissipate more heat from the key components," Gigabyte says.
This card draws power from two 8-pin PCIe connectors. Display outputs consist of three HDMI 2.0b ports supporting up to 4K at 60Hz and three DisplayPort 1.4 connectors supporting up to 8K at 60Hz.
Gigabyte did not say when this card will be available or for how much.
