Linux patches have already given us a "lot" of information (using "lot" generously there) on AMD's upcoming Vega graphics cards. I'd wager few enthusiasts would be looking towards a dual-GPU solution anymore - not with the mostly absent support from most recent games, of which Prey is a notable exception. Not unless there was some sort of hardware feature that exposed both dies as a single GPU for games and software to handle, but I'm entering the realm of joyous, hopeful thinking here.

Back to the facts, a May 10th Linux patch has added two more device ID's to a Vega family of products: 0x6864 and 0x6868. These additions bring the total number of Vega device ID's to a healthy 9, which is still less than Polaris' 12. This is in-line with the expected number of SKUs for Vega, which should be less than those available for Polaris.
