To my (limited) knowledge the INT4, INT8, FP16 and FP32 types are incorporated into the RDNA2 shaders themselves. Remember datatypes could be used on anything from textures to compute/ML (integers are mostly used for ML since it doesn't need the precision of floats), so this setup makes it quite dynamic and powerfull for devs to use them as they see fit.DirectML short for Direct Machine Learning is AMD equivalent answer to Nvidia's DLSS short for Deep Learning Super Sampling, Enabling higher performance levels by using machine learning to upscale images to higher resolutions without visual downgrades.
AMD has an answer to Nvidia's DLSS, and that answer is DirectML-powered Super Resolution. AMD plans to utilise Machine Learning to improve the visual quality of games, & AMD's solution will have the backing of Microsoft.
Microsoft confirmed that both of their next-generation consoles would support Machine learning for games with DirectML. Through their collaboration with AMD when creating their new consoles.
A component of Microsoft's DirectX feature set DirectML isn't a Radeon-only technology, and its applications extend far beyond Super Resolution functions. Over the coming years, future PC and Xbox games will bring Machine Learning into games in several new and innovative ways, impacting all gamers with supported hardware.
Microsoft has already showcased the potential of machine learning in gaming applications, with the image below showcasing what happens when Machine Learning is used to upscale an image to four times its original resolution (basically from 1080p to 4K) to generate a sharper final image with reduced aliasing. The image below is a comparison between ML Super Sampling and bilinear upsampling.
PS5 is confirmed to not use DirectX feature so even though AMD made their CPU and GPU for the PS5 it looks like PS5 will not have DirectML
so will Sony come up with alternative method to compensate for not having this feature cause Machine Learning is the future of gaming.
While DirectML hasn't received as much attention as DirectX raytracing, you can be sure that developers are looking at the new API closely. As screen manufacturers are starting to push beyond 4K, AI upscaling technologies like Machine Learning will continue to increase in popularity. 4K gaming is already a challenge for modern gaming hardware, and 8K is going to prove to be even more problematic for game makers and hardware vendors.
Technologies like DirectML will become vital for future games, both on PC and on consoles. The application of machine learning will allow developers to deliver higher levels of graphical fidelity without the insane hardware costs of traditional computational methods.
So the "ML" part isn't a block of dedicated transistors (i.e. like the decompression hardware in the new consoles), so this boils down to the fact if Sony has the same RDNA2 CU's in their PS5 or not.
If we are going by what Cerny has said before (Road To PS5), they do. And frankly the thought of Sony customizing every CU sounds both expensive and a bit unrealistic.
The PS5 don't have DirectML ofc since that's a part of the Direct-X suite, but as long as the hardware are present they would have no problems utilizing ML with either a 3rd party api or their own solution.
