Intel XeSS is designed to take a game rendered in 1080p and convert it to 4K using AI.
In theory, this means it offers the same advantages as Nvidia's DLSS. The main benefit is that you can play games at lower resolutions and therefore higher FPS, and use the technology to produce an image with higher resolution while preserving similar FPS.
Like AMD's FSR, it should gradually become fully open source, although some limitations will still remain. Intel is therefore trying to bring together the best of both technologies with XeSS just by activating an option within the game's settings. There are already over 70 games that support XeSS and Intel promises more will be added in the future.
Intel treats upscaling and anti-aliasing as a single package via machine learning, which helps synthesize images that are very close to the quality of native ultra high-resolution rendering by reconstructing sub-pixel details from neighboring pixels, as well as from previous motion-compensated images. This reconstruction is performed by a neural network permanently trained on previous images.
Intel Xe Super Sampling works with all graphics cards supporting Shader Model 6.4+ and DP4a instructions. Naturally, XeSS performs best on Intel's Arc graphics processors, but it will also work with Nvidia and AMD graphics hardware.
The following Series' of GPUs support Intel XeSS, however, the more powerful the GPU, the greater the efficacy of XeSS.
