Intel launched a product code-named Alchemist (DG2) at the IntelArc brand independent graphics card conference last year, and also brought an artificial intelligence-driven super-sampling technology called XeSS. XeSS accelerates through XMXAI in the Xe-HPG architecture Xe core (XeCore), using ML to reconstruct low-resolution frames into high-resolution frames, increasing the number of running frames. It is also fully compatible with DirectX12, and relies on DP4a instructions to provide AI-based super sampling on various hardware including Ruixuan GPU and integrated graphics card.
At present, both NVIDIA DLSS and AMDFSR have added frame generation functions, which can improve the performance of game running through interpolation, greatly increasing the number of frames while ensuring picture quality. According to Wccftech, Intel is about to bring a solution called "ExtraSS" to achieve the same effect.
Anton Kaplanyan, Intel Vice President of Graphics Research, introduced ExtraSS technology in his speech at SIGGRAPHASIA 2023. This is a new framework that combines spatial supersampling and frame extrapolation methods, which can improve real-time rendering performance, achieve a balance between performance and quality, and generate time-stable, high-quality, high-resolution results. Compared with traditional rendering methods, the computational cost will also be greatly reduced.
Currently, NVIDIA DLSS and AMDFSR use frame interpolation methods to generate approximate frames based on multiple old and new rendering samples, while Intel's ExtraSS produces new approximate frames based on old renderings. NVIDIA and AMD's methods will add additional latency, so they will rely on technologies such as Reflex and Anti-Lag+. ExtraSS has little impact in this regard, but the problem is that the generated effects may not be very good, and Intel also said that it is trying to solve these problems.
Intel did not disclose the release time of ExtraSS, and next year should bring more news.
