Radeon and Geforce are tested with DirectX 12 in SLI-like configuration

The new DirectX 12 interface allows developers to work closer to the hardware, to be able to make more efficient use of resources. Most notable is the possibility of significantly more drawing calls and multi-core support compared to previous DirectX versions, but these are just some of several major news.

Another feature that has been noticed is Multiadapter, which gives developers more control over solutions with multiple graphics circuits. This can be divided into three categories. The first is Implicit, where the responsibility, as with previous DirectX versions, largely lies with AMD and Nvidia. The other is called Explicit and gives more control to developers, who can choose how the support should be designed.

The third and last is called Explicit Multiadapter – Unlinked GPUs, where developers are free to use all the resources in a system. It makes it possible to mix solutions between different players, for example by using integrated graphics circuits from AMD or Intel with a dedicated graphics card from AMD or Nvidia.

Now the technology side Anandtech has had the opportunity to test an early version of Ashes of the Singularity with support for the latter. The test includes the graphics cards Geforce GTX Titan X, GTX 980 Ti, Radeon R9 Fury X and R9 Fury, which combine several different configurations in the resolutions 2,560 x 1,440 and 4K UHD.

When the Radeon R9 Fury X and Geforce GTX 980 Ti are run together, the performance boost amounts to 68–75 percent, depending on which graphics card is used as the primary one. Extra interesting in this context is that the duo goes over the configurations with two graphics cards from AMD and two from Nvidia.

In addition to testing the latest top models, the site takes a step back to 2012, where the Radeon HD 7970 and Geforce GTX 680 reigned at the top. Unlike the other tests, the choice of primary graphics card is of extra great importance, where the GTX 680 primarily produces poorer results than the duo individually. When the HD 7970 takes the lead, it is instead about a 55 percent better result than when driving alone.

It is worth mentioning in this context that the test version used is not even qualified as an alpha variant of Oxide, so the figures should be taken with a pinch of salt for the time being.
