AMD Fidelity FX Super Resolution
Announced on the occasion of the presentation of the Radeon RX 6000 series graphics cards, based on the RDNA 2 architecture, the FidelityFX Super Resolution (FSR) technology should be the AMD equivalent of NVIDIA's DLSS, allowing you to maximize in-game performance even at high resolutions with an imperceptible loss of image quality. Currently we do not know when exactly it will be available to the public, although, according to a recent video by Coreteks, it could arrive as early as next month.Until now we were not sure of the functioning of the algorithm used, but it is A new patent registered by AMD has been identified that sheds light on some aspects. In fact, the document reads:
[…] A “super resolution” processing method is provided which improves the calculation performance. The method includes receiving an input image with a first resolution, generating linear subsampled versions of the image via a linear upscaling network, and generating nonlinear subsampled versions of the input image via a network downscaling. of non-linear upscaling. The method also includes converting the subsampled versions of the input image into the pixels of an output image having a second resolution higher than the first and reproducing the image on the screen. […]
[…] The device 100 may include, for example, a computer, a gaming device, a portable device, a set-top box, a television, a mobile phone or a tablet. Device 100 includes a processor 102, a memory 104, a memory 106, one or more input devices 108 and one or more output devices 110. The device 100 may also optionally include an input driver 112 and an output driver 114 It is understood that the device 100 may include additional components not shown in FIG. 1. [...]
In practice, this means that AMD engineers will use linear and non-linear upscaling technologies to deliver optimal image quality, so as to accurately reconstruct missing pixels. Furthermore, FidelityFX Super Resolution will not only be used on PC, but also on multiple devices, such as consoles, smartphones, smart TVs and others. Despite being filed last November, the patent, as noted by VideoCardz colleagues, was only recently made public.
The AMD Ryzen 5 5600X processor, equipped with six cores and twelve threads, is available for purchase on Amazon at a discounted price.
AMD Gaming Super Resolution receives patent; could we expect FidelityFX Super Resolution sooner?
Finally, we see some positivity surrounding AMD’s alternative to NVIDIA’s DLSS, which has now added over 50 games to its library already. For the last couple of months, we are only hearing that AMD will soon launch FidelityFX Super Resolution and will be platform independent.
While the last leak suggests that it will eventually launch in June itself, which already stunned us because AMD’s Scott Herkelman previously said that it will be released this year without specifying any solid timeline.
However, it seems like the June announcement could be true because the new patent signifies that AMD had finally chosen the technology behind FSR. Also, this patent could be one of the many patents that AMD will submit to USTPO, so FSR could still use different technology as well.
In the patent it is stated:
A processing device is provided which improves processing performance. The method includes receiving an input image having the first resolution, generating linear down-sampled versions of the input image by down-sampling the input image via a linear upscaling network and generating non-linear down-sampled versions of the input image by down-sampling the input image via a non-linear upscaling network. The method also includes converting the down-sampled versions of the input image into pixels of an output image having a second resolution higher than the first resolution and providing the output image for display.
As the description states, and what AMD said previously, this approach of upscaling images will work on a variety of processing units, including CPUs or GPUs or clusters of each. AMD’s solution states that using linear and non-linear upscaling technology that will preserve and improve the fidelity of the image and will “create high-quality image approximations and achieve high framerates”.
So, as previously Coreteks said AMD’s tech is irrespective of the device itself can render images on any GPU, CPU or device even on consoles or handheld device or smartphones. Originally submitted in November 2019, the patent was only made available today and it makes things more exciting as AMD’s tech is more generalized.
