During its 2022 Investors Meeting, Intel confirmed that it will be shipping its first Arc Alchemist Desktop discrete graphics cards in Q2 2022.

It looks like Intel themselves have confirmed that while Arc Alchemist GPUs will be coming to the notebook segment in the first quarter of 2022, desktops will get the discrete graphics card update by the second quarter of 2022 while workstations will get the first Arc Alchemist powered products by the third quarter of 2022.
