The Gigabyte Radeon RX Vega 64 Gaming OC 8G comes sporting a black and red Windforce 2X cooler design but sorry, no LED lighting.
Adding on to the recent slew of custom RX Vega announcements, last week Gigabyte announced the Radeon RX Vega 64 Gaming OC 8G, featuring their dual-fan Windforce cooling system. The 2.5 slot width card comes with a very mild factory overclock of 1560MHz boost and 1276MHz base, but otherwise brings the usual amenities of high-end custom designs: 12+1 power phases, backplate with copper slug and heatpipe, and zero fanspeed idle under their “3D Active Fan” branding, where fans turn off under lower temperatures or loads.
The rest of the Windforce 2X design is fairly standard for Gigabyte’s high-end models. Underneath the two 100mm alternate spinning fans, the aluminum heatsink’s five copper heatpipes make direct contact with the GPU, and presumably the HBM2 as well. On the rear, the metal backplate features a copper plate behind the GPU and a copper heatpipe, features that are not typically present in Gigabyte’s budget models. Altogether, the heatsink with rear copper plate and heatpipe complex is an interesting design choice to complement the dual fan design, and ideally would mitigate the lesser cooling potential versus three fans.
Those twelve phases get power through a pair of eight-pin PCIe power connectors. Gigabyte recommends a beefy 750 W power supply to go along with the card. The board and cooler measure 10.8" long, 2.1" thick, and 5.2" deep (27.3 cm x 5.3 cm x 132 cm), so users will need to allow for three slots' worth of space.
The Gaming OC also differs from AMD's reference design in its selection of outputs. The card has three full-size DisplayPorts and three HDMI 2.0b connectors for good measure. The manufacturer says the card can drive six displays at once, compared to four on reference RX Vega cards.
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.
