AMD Could Do DLSS Alternative with Radeon VII through DirectML API

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.

RT cores are worthless but at same time taking A LOT of space on die

Source on that please.

DirectML driver could potentially work on every Direct3D 12 hardware, not a big surprise it that it can be used on the upcoming radeon, and it can run on CPU side too. The question is: will AMD spend time and money to optimize DirectML meta-commands and it DLSS implementation on all it's hardware?

The full Direct X 12 feature set was only included in the last few generations, so they may well do. Also, having it additionally run on CPU could be of huge benefit for older cards if they could run it concurrently on GPU and CPU.

Of course, that's all wishful thinking at this point.

Part of me feels they did this just to spite Huang's comment.

Not that I'm complaining.

ATM after moving from AMD to NV it looks like this:
NV comes up with Gsync and charges for it. AMD sees it and not wanting to be BEHIND introduces Freesync
NV starts to push Ray Tracing. AMD sayw we can do this TO
NV comes up with DLSS and AMD says we can do that TO

It's hard for Me to think of a tech that AMD came up with that NV ripped off in last few years. Well I purchased 290x cause MAntle and True Audio ware things that AMD came up with. Played BF4 on Mantle and TrueAudio was DOA not played anythign that uses it.
I guess this is what happens when You are a Leader on marker, You put some tech out and chasing competition NEEDS to adopt the technology or they will loose market %.


I knew NV will keep Freesync option as ACE CARD when they will need it aka RTX does not sell as good as they expected.
