This week Intel introduced the brand Arc, under which video cards for gamers will be produced. The first generation will be based on microarchitecture Xᵉ HPG codenamed Alchemist and will receive support for hardware real-time ray tracing, artificial intelligence-based supersampling technology.
At the event Intel Architecture Day the manufacturer shared the details of the analog DLSS from NVIDIA and FidelityFX Super Resolution from AMD… Judging by the slides, Intel technology will be called Xᵉ Super Sampling (Xᵉ SS) and will become an open source solution that can work on any video card.
The Xᵉ SS will use the DP4a and XMX instructions found in the released DG1 (Xᵉ LP) GPUs and will also appear in the upcoming Intel Xᵉ HPG (DG2) series. The Matrix Engine and Vector Engine accelerate the work of AI at an iron level. Each DG2 chip will be powered by 16 Matrix Engine and 16 Vector Engine.
During the presentation, Intel showed a real-time demo of the Xᵉ SS. According to what we saw, we can conclude that the picture in 1080p resolution is upscaled to 4K using Xᵉ SS supersampling a little slower than usual.
It is worth noting that using the XMX shows much better results than the DP4a. To “restore” the picture, Xᵉ SS uses the information obtained from the previously rendered frames. NVIDIA uses a similar approach, while AMD works with the original frame in low resolution.
The complete line of ARC-based graphics chips is as follows:
- Xᵉ HPG – Alchemist
- Xᵉ² HPG – Battlemage
- Xᵉ³ HPG – Celestial
- Xᵉ new architecture – Druid
The Xe-HPG-powered Alchemist will debut in the first quarter of 2023.
