Intel Arc[2][3] is a brand of graphics processing units designed by Intel. These are discrete GPUs mostly marketed for the high-margin PC gaming market. The brand also covers Intel's consumer graphics software and services.

Intel Arc is set to compete with Nvidia's GeForce and AMD's Radeon lines.[4] The Arc-A series for laptops was launched on March 30, 2022, with the Arc 5 and 7 "set to arrive later this year in 'early summer.' "[5][6]

Intel officially launched the Arc Pro workstation GPUs on August 8, 2022.[7][8]

Etymology

According to Intel, the brand is named after the concept of story arcs found in video games.[9]

Graphics processor generations

Alchemist

Developed under the previous codename "DG2", the first generation of Intel Arc GPUs (codenamed "Alchemist") is slated for release by March 30, 2022.[1][10] It will come in both add-on desktop card and laptop form factors. TSMC is set to manufacture the die, using the TSMC N6 process.[11]

Alchemist uses the Intel Xe GPU architecture, or more specifically, the Xe-HPG variant. Alchemist will support hardware-based ray tracing, XeSS or supersampling based on neural networks (similar to Nvidia DLSS), and DirectX 12 Ultimate.[1][12] Also supported is DisplayPort 2.0 and overclocking. AV1 fixed-function hardware encoder is planned for this GPU as part of Intel Quick Sync Video core.[13]

Intel confirmed ASTC support has been removed from hardware starting with Alchemist and future Intel Arc GPU microarchitectures will also not support it.[14]

Intel revealed that Meteor Lake and later generations of CPU SoCs will use Intel Arc Tile GPU.[15][16]

Intel Arc Alchemist does not support SR-IOV.[17] Intel Arc Alchemist does not support D3D9 natively.[18]

Intel Arc support OpenCL 3.0 for example, this GPU can work in the grid World Community Grid.[19]

Future generations

Intel also revealed future generations of Intel Arc GPUs under development:[3][6] Battlemage (based on Xe2), Celestial (based on Xe3), and Druid. Battlemage will succeed Alchemist.

Intel revealed that Lunar Lake and later generations of CPU SoCs will use Intel Arc Tile GPU.[15]

Intel XeSS

Intel XeSS is a real-time deep learning image upsampling technology developed primarily for use in video games as a competitor to Nvidia's DLSS and AMD's FSR technologies. Additionally, XeSS is not restricted to Intel Arc graphics cards. It does utilize XMX instructions exclusive to Intel Arc graphics cards, but will fall back to utilizing DP4a instructions on competing GPUs that have support for DP4a instructions. XeSS is trained with 64 samples per pixel as opposed to Nvidia DLSS's 16 samples per pixel (16K reference images).[20][21]

Quality Presets

Standard XeSS presets[22]
Quality Preset[lower-alpha 1] Scale Factor[lower-alpha 2] Render Scale[lower-alpha 3]
Ultra Quality 1.30x 77.0%
Quality 1.50x 66.6%
Balanced 1.70x 58.8%
Performance 2.00x 50.0%
Ultra Performance 3.00x 33.3%
  1. ↑ The algorithm does not necessarily need to be implemented using these presets; it is possible for the implementer to define custom input and output resolutions.
  2. ↑ The linear scale factor used for upsampling the input resolution to the output resolution. For example, a scene rendered at 540p with a 2.00x scale factor would have an output resolution of 1080p.
  3. ↑ The linear render scale, compared to the output resolution, that the technology uses to render scenes internally before upsampling. For example, a 1080p scene with a 50% render scale would have an internal resolution of 540p.
