Over a year ago we did a GeForce then and now articleand video. In there we promised a Radeon Retrospective as well. Yes, over a year ago, I know. We had several different ideas and all of them fell through for some reason or another until now. Having secured a reference design Radeon HD 7870 GHz Edition we now had a GCN 1.0 Mid Range Graphics Card on hand to compare to Radeons current mainstream card, the GCN 4.0 based RX 480. I know that the RX 580 is now but we all can agree that it's a refreshed RX 480 so what we're looking at here is non refreshed original iterations of both Radeon's first 28nm GPU and their 14nm GPU.
