ASRock was rumored to be working on new graphics cards, as the Taiwanese manufacturer would enter as a new AIB partner for AMD Radeon according to reports, and now the company is fully teasing their upcoming Phantom Gaming graphics cards. Check out the trailer:
ASRock teases: "Mystery videos published... Look forward to the announcement! #ASRock #PhantomGaming #PG #Phantom #Gaming #FAST #MYSTERIOUS #UNPREDICTABLE".

We can see the card looks like a dual-slot affair with a single 8-pin PCIe connector, so we should expect it to arrive as a custom Radeon RX 580 and not a custom Radeon RX Vega 56/64 as they require 2 x 8-pin PCIe power connectors. We could be surprised, but I doubt it.

I'd say ASRock are testing the waters before fully unleashing a range of custom graphics cards, and what I'm expecting more: mining-focused cards soon enough.
