AMD and Xilinx cooperated on HBM2

Not a lot of details here, but FUD Zilla managed to confirm that Xilinx helped AMD with HBM2. The site says both companies have quietly been cooperating for years on next-gen memory interfaces, as both firms realized they were after the same goal.

Increasing the memory bandwidth is the key for both computer graphics that AMD is perusing and for deep learning, high quality video processing and AI that both companies are now after. Stacking memory chips to increase the bandwidth was no walk in the park and both companies worked together to fix the obstacles.

Interestingly, the current CEO of Xilinx, Victor Peng, used to be a VP of silicon engineering at ATI and later AMD.
