The total number of AIBs sold in 2015 was 50 million compared to 44 million in 2014. Of these, about 5.9 million are enthusiast level AIBs (add-in boards / discreet graphics cards) shipped in 2015 compared to 2.9 million in 2014. That rise in enthusiast AIB shipments, while the PC and overall AIB market was declining, was due to the great new games that were brought out in 2015. And, even though neither AMD or Nvidia introduced any killer new AIBs in 2015, sales went up. This is paramount proof that the enthusiasts and their followers want, and will pay for great games and hardware if it is compelling.
