Recently Intel officially released an official introduction to XeSS technology. It is said to be in conjunction with the new graphics card launched next month, probably A770. Now that the frame rate optimization technologies of NV and AMD have become a mess, and even market segmentation is in play, what are the features of Intel XeSS, a newbie? Let’s learn about it from the official document https://www.intel.cn/content/www/cn/zh/products/docs/arc-discrete-graphics/xess.html today.
From the full name of XeSS - Xe Super Sampling, we can guess that its basic functions are actually similar to NV and AMD's high-end frame rate optimization technologies DLSS and FSR 2.0. In terms of implementation, it is "a machine learning approach to reconstruct sub-pixel details through adjacent pixels and motion compensation previous frames, helping to synthesize images that are very close to the native ultra-high resolution rendering quality. The reconstruction is performed by trained Neural network execution to provide high performance and excellent quality. "
As for the execution unit, yes, Intel's Xe display core also has the AI computing unit. What should be noted here is that the Vector Engines in the Xe core seem to have similar names to the AI processing cores of other chips, but they are actually graphics processing units. The real AI engines are Matrix Engines. The area is small, but the 1024-bit computing power is still quite powerful.
In terms of actual performance, Intel directly released a comparison of the A770, probably because the frame rate of the A380 that is already on the market is not good even after optimization. Judging from the official test results, after turning on XeSS performance mode at 2K resolution, the frame rate of the A770 can be increased by up to 2.11 times and as low as 1.37 times at the highest image quality of the game (if ray tracing is also enabled) .
The quality mode is 1.8 times the native image quality, and the super quality is 1.5 times the native image quality. From the comparison renderings provided on the web page, after turning on XeSS, the perception of image details has been significantly enhanced. However, some jaggedness is also added to the edges.

Here is another feature of XeSS, that is openness. According to Intel, it is actually an open standard optimized for Intel Xe GPU. In this regard, It is quite similar to FSR. Theoretically, the game does not need to be submitted to Intel in advance for adaptation. As long as the corresponding SDK (software development kit) is used, the frame rate can be optimized on Intel and other graphics cards, but it is more efficient on Intel graphics cards.
From this point of view, Intel actually provides players and software and hardware manufacturers with a "stitched monster" choice. XeSS frame rate optimization technology not only has highly efficient hardware AI acceleration capabilities, but also can be opened to other graphics cards. Watch Really good. However, whether it will be more widely accepted depends on future development. As for the current situation, interested friends can check out the list of games and manufacturers.
