AMD have begun shipping Polaris GPUs from the foundries. Based on the information from Zauba, it seems to be two different Polaris chips/families, each with 2 different SKUs/GPUs. Total of 4 new Polaris GPUs. The one with the biggest value is the full Polaris while the other one is the same Polaris GPU but with some shaders/cores disabled.
Polaris chip #1:
GPU #1: Board number: C981
This one is the full chip
GPU #2: Board number: C980.
Based on the value and the board number I would guess that this one is the same as above but have some shaders/cores disabled. Like Fury X and Fury.
Polaris chip #2:
GPU #3: Board number: C924
GPU #4: Board number: C913
Board number: C880
Board number: C888
R9 200/300 series: Board number C6xx and C7xxx.
If you are unsure about board numbers, TechPowerUp have a good database where you can search around
200/300 series have these board numbers: 6xx and 7xx.
Fiji have: 8xx.
Looks like AMD will be first to market with the next generation after all
