AMD Phasing Out CrossFire Brand With DX 12 Adoption, Favors mGPU
An AMD representative recently answered PC World's query regarding the absence of "CrossFire" branding on their latest Radeon Software release, which introduced multi-GPU support for AMD's Vega line of graphics cards. According to the AMD representative, it goes down to a technicality, in that "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."
The CrossFire branding has been an AMD staple for years now, even before it was even AMD - it was introduced to the market by ATI on 2005, as a way to market multiple Radeon GPUs being used in tandem. For years, this was seen as a semi-viable way for users to space out their investment in graphics card technology by putting in lesser amounts of money at a time - you'd buy a mid-range GPU now, then pair it with another one later to either update your performance capabilities to the latest games, or achieve the same performance levels as a more expensive, single-GPU solution. This has always been a little hit or miss with both vendors, due to a number of factors.
But now, the power to implement CrossFire or SLI isn't solely on the GPU vendor's (AMD and NVIDIA) hands. With the advent of DX 12 and explicit multi-adapter, it's now up to the game developers to explicitly support mGPU technologies, which could even allow for different graphics cards from different manufacturers to work in tandem. History has proven this to be more of a pipe-dream than anything, however. AMD phasing out the CrossFire branding is a result of the times, particular times nowadays where the full responsibility of making sure multi-GPU solutions work shouldn't be placed at AMD or NVIDIA's feet - at least on DX 12 titles.

Essentially I read that multiGPU is dead until game developers need to use it.
One relies on profiles, the other shifts every bit of support off to devs.Sadly, that is my expected outcome.
AMD spend less time on rename, more time on better scaling of features said to work, please. :)

It may still fail simply because people just aren't buying multiple cards but not necessarily because it will be crap.
So they could also combine the GPU memory too.
Like Ryzen sharing loads and cache memory.
Which may suck if you have a multi GPU setup, but the market penetration is in the low single digits anyway.
