AMD Could Do DLSS Alternative with Radeon VII through DirectML API
There is an interesting development, as you know the GeForce RTX graphics cards have tensor cores, dedicated cores for optimizing and accelerating anything AI and Deep Learning. A spawn from that technology for gaming is DLSS, which NVIDIA is marketing strongly. With the October 2018 update for Windows 10, Microsoft has released the DirectML API for DirectX 12.
ML stands for Machine Learning - and makes it possible to run trained neural networks on any DX12 graphics card. Basically, the Deep Learning optimization or algorithm if you will, becomes a shader that can be run over the traditional shader engine, without a need for tensor cores. In an interview with AMD they mention that the team is working on this and it seems, Radeon VII seems very well suited for the new API. Japanese website 4gamer.net spoke with AMD marketing manager Adam Kozak, AMD is currently testing DirectML with Radeon VII and was positively impressed by the results, and that is exciting news for AMD offering them an AI/DL alternative.
While AMD is testing this on Radeon VII, logic obviously dictates that it would work well on Radeon RX Vega 64 and Radeon RX Vega 56 as well. This allows, for example, an alternative implementation to Nvidia's DLSS.
Only 1+1=2
Of course, should this become an actual supported thing, then it can't be addressed AMD alone, this question remains: will game developers actually implement, experiment and integrate support for DX ML into games?
It also has to be said, it works reversed, DirectML could also make use of Nvidia's Tensor cores, certainly giving them an advantage. As the Radeon card would see a performance hit, whereas the RTX cards can simply offload the algorithm towards its Tensor cores. Time will tell, but this certainly is an interesting development as long as your graphics card is powerful enough, of course.
AMD Could take Back 30% of the Processor Market - 09/26/2018 07:55 AM
Good times for AMD. Intel is under a lot of scrutinies lately, scandals with their top-tier staff, issues with 14nm production, delays at 10nm and vulnerabilities are only a few of them. Meanwhile...

Is it possible by MS DXR to assign 1 GPU for Ray-tracing calculation while primary GPU handles the gaming? like PhysX in the old days?
Asking if MS DXR API can support this task .
So in future you can get GPU like Vega64/1080TI and you add RX 580 for ray-tracing to reduce the performance impact?

Sure. RX580 won't reduce anything though, it's not capable of running any noticeable amount of raytracing in real time.

OK, so Lets say 2080TI+2080TI For 4K High FPS gaming if you just won the lottery

Just asking from the Code perspective, to see if in future we gonna be back to multi-GPU rigs.
