The white GPU series in the PowerColor lineup are nothing new. The company has been experimenting with the idea for a couple of years already, with numerous launches of Hellound White models. The those cards typically offer white cooling and even PCBs, which is not a very common thing for graphics cards. It looks like the RDNA3 series may soon get such a model from PowerColor, who would be releasing their Radeon RX 7900 XTX card just a week after ASRock Taichi model. The company has just teased the new Hellhound card on their social media.
The Spectral White is a name of the design featuring a white backplate and PCB, this model should also have blue LEDs. This post confirms we are looking at the 7900 XTX GPU, equipped with two 8-pin power connectors. However, this may be as far as PowerColor may go with their white GPU series, as there was never a white Red Devil (a higher-end GPU in the manufacturer’s lineup).
