Intel XeSS AI scaling tests on Intel, NVIDIA and AMD graphics card resolutions, results differ


Intel introduced XeSS this week. Until the Intel Arc A7 graphics card is currently available, the new solution can be tested on mobile versions of Arc, budget A380, AMD and NVIDIA based on unreleased AMD/NADIA compacts. A series of tests were conducted by resource journalists Toms Hardware and PCGamer. The game is the same as Shadow of the Tomb Raider.

Intel XeSS is available in two flavors, one for XMX cores on Arc processors and one for DP4a instruction, supported by most modern graphics cards including NVIDIA Pascal, 11th Gen Intel Graphics and AMD Vega 20 , Navi and newer.


PCGamer journalists took a Samuray GPU as a test sample and compared performance in three ways: with scaling disabled, as well as with XeSS and DLSS. Video cards from own resources displayed an average of 3440 1440 pixels, while XeSS and DLSS showed the quality of the results in 11.2 and 119 frames.

The resource group ran a very thorough test using multiple previous generation NVIDIA and AMD video cards and their current versions at an incredible 257,143ft resolution. The results showed some interesting results: Intel XeSS worked on all tested models, but did not always provide a significant performance improvement, and in some cases performance decreased, sometimes even significantly. The authors said that the negative effect was the fact that only in emulator mode DP4a instructions are supported, and in particular, the first generation Vega and Navi graphics processors.

On several occasions, a slight increase in performance was due to insufficient video memory, although 6 GB is not that small for a four-year-old game. Modern video card models have mainly confirmed the use of XeSS over native rendering. The result was especially interesting for the budget Intel A380, the performance of which was increased by varying the settings, from the native 26.5 to 58.7 frames per second more than twice.
