I can't see that happening. Navi 10 is a replacement for Polaris 30. Polaris 30 is a 7 tflop chip with 36 CU's, so 13 tflops and 60 CU's would be nearly double it's predecessor. AMD has never managed to release a new GPU generation with a performance improvement of more than 1.5x over the previous generation afaik. For instance, Polaris 30, RX 590, offered a 1.4x improvement in flops over the previous generation GPU it replaced, the R9 390.
SO you contradicted your own original post??? AMD gonzalo is based on Navi 10
