A tech blogger has posted unofficial renders of the Intel Arc Alchemist desktop graphics card reference design. It's claimed the images of the dGPU were not based on guesswork and accurately represent the test cards. The same source also gave some idea of when both the laptop and desktop variants of Intel Arc Alchemist could be released.
