AMD's new Radeon VII series is out now. The part that matters for us:

Stock speed 1400 MHz): 11.136 TFLOPS FP32 and 2.784 TFLOPS FP64

Boost (1750 MHz): 13.824 TFLOPS FP32 and 3.4585 TFLOPS FP64.

This makes the new VII nearly equivalent to 3.5 7970's for FP64. Insanity.

Edit: Oh, and it has 16GB of VRAM
