This summer, AMD's Lisa Su showed the world a dual-GPU Fiji card. That card, codenamed "Gemini," was apparently meant to have launched by the end of this year, but that release has now been pushed back to "early Q2 2016."
In a statement to Hardware.fr (Google translation here), AMD says that it intended to launch Gemini around the same time that Oculus and its competitors were to have started selling their headsets. As more and more companies set their headset launches for 2016, though, AMD chose to wait, too. Here's the company's statement in full:
The product schedule for Fiji Gemini had initially been aligned with consumer HMD availability, which had been scheduled for Q415 back in June. Due to some delays in overall VR ecosystem readiness, HMDs are now expected to be available to consumers by early Q216. To ensure the optimal VR experience, we're adjusting the Fiji Gemini launch schedule to better align with the market. Working samples of Fiji Gemini have shipped to a variety of B2B customers in Q415, and initial customer reaction has been very positive.
It's not entirely clear why AMD is locking the release of this dual-Fiji card to VR headsets' launch timelines. Other graphics applications, like 4K gaming, could certainly use the extra oomph today. It's possible that the company simply saw an opportunity to take more time to tweak the card and its drivers before a broad launch.
