One of the interesting advancements in DirectX 12 is the way it allows graphics cards from different manufacturers to be paired together. Traditionally if you wanted a multiple GPU setup, you had to get two cards from the same manufacturer and often they had to be the same model too.

But DX12 is giving developers much more control over accessing and manipulating GPUs, and one manifestation is the freedom to pair different GPUs. It will still take a few years before the real-world benefits become much more commonplace, but the first benchmarks are in and the results are highly intriguing.
