Back in august, when AMD launched its Radeon RX Vega graphics card, it was not yet possible to combine multiple cards in a CrossFire configuration. About a month later, a driver patch came which included the multi-GPU support. Due to many big releases in the last couple of months, we did not have much time take a closer look at this, so we shall rectify this now.

In the presentation AMD gave to the international hardware press prior to the Vega-release, the word CrossFire was not mentioned once. At the launch of the RX 480 and later the RX 580 AMD hinted at performance expected out of two cards, but they have not yet launched their top of the line GPUs, so the hints have gone mostly unnoticed.
