AMD to Ditch CrossFire, New Multi-GPU Technology Possible

Maciej Borkowski



The way that multiple GPUs was handled was either SLI from NVidia or CrossFire from AMD. Now, we see that this could possibly change. Apparently, DirectX 12 handles multi GPU setups differently, thus all DX12 games will not be using CrossFire. For example, new AMD drivers have enabled gamers to use multiple Radeon RX Vega cards inside gaming PCs. This shows that CrossFire isn’t really necessary. An AMD rep said:

CrossFire isn’t mentioned because it technically refers to DX11 applications. In DirectX 12, we reference multi-GPU as applications must support mGPU, whereas AMD has to create the profiles for DX11. We’ve accordingly moved away from using the CrossFire tag for multi-GPU gaming.

CrossFire Out, In-game mGPU Support In

While the situation might seem weird for gamers, it’s only for the best. DX12 handles mGPU stuff differently than it’s predecessors. DX12 makes in-game support of multiple GPUs a requirement for the game development team. This could make mGPU setups more versatile than they were before. It means better quality and performance, although at a greater cost for the developers. Historically, DX9, DX10 and DX11 games relied more heavily on AMD and NVIDIA to offer their respective CrossFire and SLI profiles in GPU drivers.


CrossFire Not Necessarily Dead For Good

AMD is going to abandon the CrossFire branding, but not support for DX11 games. Gamers can sleep without worry, since this won’t suddenly mean that they’ll have to ditch their multi GPU setups if they intend to play mostly older game titles. AMD Radeon RX Vega cards are expected to surface in October, and here is where we will see the new mGPU tech truly shine.
