Although it is meant to be used for Arc A350M and A370M mobile GPUs, the Intel Beta 126.96.36.1992 Arc graphics driver, actually includes references to many other Arc series GPUs, including the desktop series GPUs as well as some Arc Pro GPUs.
In case you are wondering, the latest Intel Beta 188.8.131.522 Arc graphics driver brings game-on driver support for Vampire: The Masquerade - Bloodhunt, Evil Dead: The Game, and Dolmen on Intel Arc A350M and A370M graphics.
As detailed earlier, Intel's Arc GPU lineup includes Arc 3, Arc 5, and Arc 7 series models, at least for now, and according to the list spotted by @momomo_us over on Twitter, there will be a wide range of graphics cards to choose from, on both desktop and mobile side.
The listed desktop cards include A770, A750, A580, A380, and the A310, as well as the Arc Pro A40/A50. There is also the A30M graphics chip for notebooks.
Intel has officially confirmed some delays as desktop cards are scheduled to roll out with Chinese OEMs first, while later arriving in the US, Europe, and the rest of the world.
