XeSS a "Second Generation" Upscaling Technology at Par with DLSS 2.0 and FSR 2.0: Digital Foundry
Intel XeSS is a second-generation upscaling technology that's at par with DLSS 2.0 and FSR 2.0, says Digital Foundry, which got an exclusive early-access an Arc A770 graphics card along with XeSS, and the latest version of "Shadow of the Tomb Raider," which features XeSS besides DLSS. The publication compared the A770 + XeSS with a GeForce RTX 3070 + DLSS, and in its testing, found XeSS to offer comparable or better image quality at low frame-times. XeSS uses a AI-ML algorithm to reconstruct details, which is accelerated by the XMX cores on Xe-HPG "Alchemist" GPUs. XeSS hence currently only supports Arc GPUs, however, the company is working on a DP4a (programming model) version so XeSS could work on other GPU architectures, across brands.
An upscaling algorithm by design adds to frame-times (time taken to render a frame to display), and in Digital Foundry's testing, the most aggressive preset of XeSS, Performance, which upscales 720p to 1440p, adds 2 ms to the frame-time. A 1080p to 4K upscaling in the same mode, adds 3.4 ms to the frame-time, which jumps from 8.8 ms to 12.2 ms (an increase of 3.4 ms). The increase in frame-times is a good trade-off when you consider the performance gained—a staggering 88 percent increase in frame-rates for 1080p to 4K upscaling, and 52 percent increase with 720p to 1440p upscaling. Frame-times increase as you move up the presets toward the Quality mode, which renders the game at resolutions closer to native-resolution, so the performance-gained is smaller. XeSS offers a preset it calls "Ultra Quality," which renders the game at a resolution closest to native, while still yielding a 16-23 percent frame-rate gain, with an output that's practically indistinguishable from native-resolution.

DLSS - XeSS - FSR - TSR
still will be waiting... not sure when these products will be out or will be seeing these leaks only
what would Nvidia prefer, sell lots of Arc and no one cares about XeSS or the opposite? easy. XeSS is a feature not a product.
its basicly proclaiming "hey we aren't entirely useless" in this market
