Users will be able to ask questions to the Radeon Technologies Group about the upcoming Fury X2, the new Polaris architecture, DirectX 12, Vulkan, AMD graphics technologies, etc. Hopefully we'll learn a few bits of new information, but unfortunately questions about Zen will not be answered as that chip is still super secret.
The Q&A is open to all topics dealing with anything under the Radeon Technologies Group (the Radeon division of AMD). Some big secrets could be unveiled this Thursday, so bring your best questions! Likely topics of discussion will most likely include Vulkan, FreeSync, GPUOpen, Polaris, Fury X2, VR, DirectX 12, and anything else you're curious about.
Don't ask about Zen. It's still a super secret.
