We’ve already mentioned Intel Xe Super Sampling (XeSS) technology, which rivals NVIDIA’s DLSS and AMD’s FSR technologies. The blue team has now provided new details about image upgrade technology. Intel executives and developers demonstrated upgrade technology while running and presented some comparative performance charts.
Intel XeSS uses an AI-based SuperSampling technique that doesn’t require per-game training for real-time processing. Arc Alchemist Xe Matrix Extensions (Intel XMX) optimized for Xe GPUs to perform best. However, in other GPU architectures, DX12 can also work using SM6.4+ and DP4a intrinsic support. This ensures that it is independent of cross-platform and hardware, and Intel says the SDK will be open source.
Together with GDC, Intel focused on how developers can use XeSS. At this session, the company announced a Unreal Engine plugin for the simplified integration of its technology into Unreal projects. It is also said that XeSS “replaces TAA in the creation line” in the projects, so it is valid after the raster and lighting are completed and should be added to the beginning of the post-processing phase.
Intel’s AI is said to mitigate the effects of shading, glare and blurring found in temporary anti-aliasing top sampling (TAAU). In addition, Intel claims that XeSS can achieve higher scaling rates than its modern competitors such as AMD FSR or NVIDIA DLSS.
The chipmaker aims to support all GPU vendors with XeSS. The company has reaffirmed that all GPUs that support shader Model 6.4+ and DP4a instructions will support this technology. Still, XeSS will work best with its own Arc and other graphic architectures with Matrix Extensions (XMX) acceleration support.
Performance and Quality Settings
As with any riser, it’s all about reducing the tension in the pixel sequential layout to allow fast frame rates at high resolutions. The trick is to do this while maintaining image quality.
The XeSS Rens demo shows a variety of high-level factors that you can see in more detail in the table below. Five quality settings were tested by running Rens at 2160p and 1440p.
Unlike AMD FSR 2.0 and NVIDIA DLSS 2.3, XeSS will have five image quality modes, including Ultra Quality mode with a 1.3X scaling factor: Ultra Performance (up to 3.0x scaling factor), Performance (2.0), Balanced (1.7), Quality (1.5) and Ultra Quality (1.3).
Intel claims its technologies can achieve higher scaling rates than other temporal and spatial upgrade techniques. Ultra-Quality mode improves performance for 1440p and 4K resolutions by 21% to 27% respectively, while Ultra-Performance delivers 97% to 153% better frame rate. In addition, these values are based on an Arc Alchemist GPU and Rens demo running at a fixed frequency.
The Blues have not yet given a launch date for XeSS and have not shared a game list. But we hope to see more in the official launch of Arc mobile graphics cards on March 30.
