Intel has historically been a CPU maker, and has completed greater than its justifiable share of labor on CPU {hardware}, in addition to software program implementations that work to boost the efficiency of its {hardware}. It has additionally had built-in graphics processors in its CPUs, but it surely hasn’t been something to write down residence about.

It now has a newfound give attention to GPUs, together with a brand new Xe GPU structure, and its personal model of picture supersampling and upscaling expertise to go together with the {hardware} — XeSS. Intel XeSS, quick for Intel Xe Super Sampling, is Intel’s reply to Nvidia DLSS and AMD FSR.

What is Intel XeSS and the way does it work?

Intel XeSS, or Intel Xe Super Sampling, is a picture upscaling expertise that makes use of each spatial and temporal information, and depends on synthetic intelligence to do it. Supersampling is an anti-aliasing expertise that takes shade samples of the pixels in a picture at completely different cases. It then makes use of this shade information and renders the picture at a a lot larger decision.

Supersampling has a bonus over the standard anti-aliasing strategies, offering a a lot better high quality high-resolution picture, with fewer obvious jagged edges and different artifacts that normally include upscaling a picture.

Intel XeSS makes use of a mix of spatial and temporal information, i.e. each picture information and movement information, with respect to time to provide the output picture. Like DLSS, it passes this information by way of a educated neural community, harnessing machine studying and synthetic intelligence to enhance picture high quality.

Intel XeSS process

Intel is making XeSS use its new XMX matrix math items current in its new Xe-HPG graphics processors to do the heavy lifting for the AI processing on the {hardware} finish. However, it additionally has a model of XeSS within the pipeline, which received’t depend on these items. This model will use the 4-element vector dot product (DP4a) instruction, which has wider help, making XeSS not restricted to the most recent Intel {hardware}.

Intel XeSS performance graph

Intel’s implementation is just like Nvidia DLSS 2.0. Both have the same method to supersampling. Intel XeSS makes use of spatial information, which is the information from the encircling pixels, in addition to temporal information, which is the movement info from earlier frames close to time. It then feeds this information to a neural community educated to upscale photographs, fairly like Nvidia DLSS does.

Nvidia DLSS, nonetheless, requires newer Nvidia {hardware} to work. On the opposite hand, Intel XeSS has two variations, as talked about earlier than. Intel is utilizing its {hardware} parts to make a higher-end XeSS, but it surely’s not abandoning customers with older {hardware} both. That units it aside from Nvidia DLSS, regardless that the DP4a model of XeSS received’t carry out in addition to the XMX model.

That’s additionally the place Intel XeSS stands just like AMD FSR. AMD FSR doesn’t require you to make use of AMD {hardware}. However, AMD FSR can be extra of a run-of-the-mill spatial upscaling expertise, and doesn’t use the hybrid method that makes DLSS pretty much as good as it’s. Intel XeSS appears like the perfect of each worlds, and a stability between DLSS and FSR. We’re but to get extra particulars about real-world efficiency, however the demos do look nice.

Intel XeSS is aiming at broad {hardware} help. The XMX model will help Intel Xe-HPG graphics processors. The DP4a model will help the Xe-LP GPU, in addition to the discrete GPUs from the previous. The expertise continues to be new, and as such, there isn’t a lot to go on about supported video games.

We obtained a customized Unreal Engine demo on the unveiling at Intel Architecture Day. Since then, Intel has put out a demo that includes Hitman 3, and The Riftbreaker, that are the 2 video games confirmed to help Intel XeSS to date. It’s possible {that a} bunch of video games will be part of the record, regardless that Intel is but to announce any strategic partnerships with recreation builders.

Intel XeSS SDK launched in August 2021. XeSS itself is predicted to launch with the Intel Arc GPUs, in Q1 2022. We can hope to see extra demos and recreation help bulletins within the coming weeks, as Intel gears as much as launch its GPU lineup.

Stay tuned for extra on Intel XeSS, PC graphics, and different related PC tech. In the meantime, take a look at these articles.
