In the case of AMD these units are in the CDNA architecture of their recently launched AMD Instinct MI100. The Denoiser Engine could mean a return to dual GPUsД¬ontemporary GPUs, at least those from NVIDIA, have a number of special drives to speed up Artificial Intelligence algorithms.

That is, the idea is to assign a coprocessor to the GPU specialized in executing neural networks and prepared to carry out the Denoising process, said coprocessor in its first versions if we apply it to contemporary GPUs can be connected to the GPU through an interface NVLink ( NVIDIA) or an xGMI ( AMD) interface within the same graphics card and receive the noisey image buffer from a DMA mechanism to copy it to its memory and apply the noise elimination process on the image generated by the GPU. There is a Disney / Pixar patent entitled Multi-scale architecture of denoising monte carlo renderings using neural networks where precisely they talk about the Denoiser Engine as a concept and I think it is something that is going to be standardized in the world of 3D graphics, not face to games, but in terms of composition of 3D images. produced by a GPU with far fewer samples. Thus, with an image with much fewer samples per pixel, the same result is achieved as one with many samples per pixel using a вЂњDenoisingвЂќ or noise elimination algorithm through Deep Learning and dedicated processors applying this algorithm to the images. Such is the computational load of this type of rendering that companies like Disney and its subsidiary Pixar decided a few years ago to start using Deep Learning networks for the reconstruction of images so that they imagine / hallucinate the complete images of their films made in CG using a very few samples. The usefulness of the Denoiser Engine in games The Denoiser Engine.The Denoiser Engine could mean a return to dual GPUs.
