Intel Arc を 解説 す る Lisa Pearce 氏 (Vice President and General Manager, Visual Compute Group, Intel Accelerated Compute Systems and Graphics Group)
The American company Intel is holding a special event “Intel InnovatiON” from 27 to 28. The main event was the announcement of the 12th generation Core, but in the main video there was an explanation of the functions related to the next discrete GPU “Arc” (codenamed : Alchemist).
The Arc is manufactured by TSMC’s 6nm process, and the top model has 32 built-in Xe cores. It has the latest features needed to run modern games, supports DirectX 12 Ultimate, supports hardware ray tracing, Mesh Shader, Variable Shading, and more.
It also has an independent AI acceleration function, which the company calls “XMX AI Acceleration”. It appears to be the equivalent of NVIDIA’s Tensor core, but as a technology to take advantage of this, the high-resolution technology “XeSS” was introduced.
XMX AI Acceleration Jobs
The XeSS technology itself is similar to what NVIDIA’s DLSS and AMD’s FidelityFX Super Resolution aim for, and the game will be rendered at a lower resolution to improve performance by reducing GPU overhead, supplementing with pixels to make it look high-resolution. You’re supposed to infer multiple frames or high-resolution images in the past, and the approach appears to be close to NVIDIA’s DLSS.
XeSS also needs in-game support, but the keynote clarified that “The Riftbreaker” works on the Alchemist (beta #22335) was used. It can be confirmed that a large number of 3D objects work smoothly while being drawn by XeSS in 4K resolution, which is finer than 1080p.
XeSS from XMX AI Acceleration can seamlessly draw 4K resolution above 1080p.
If you double or quadruple, the difference is obvious
Another feature of the Arc is the “Deep Link” technology already available in the entry level Xe MAX. Deep Link uses both a GPU encoder with embedded CPU and a separate GPU encoder at the same time to shorten transcoding time, but it is also available in Arc.
In the keynote speech, it was emphasized that if HandBrake video conversion software is used to perform format conversion through Xe graphics format with CPU and Arc, the time can be significantly reduced.
It also supports Intel Deep Link

The conversion work was completed earlier when the GPU with integrated CPU and discrete GPU were run in collaboration with Deep Link.
