A poster named 'iLeakStuff' on overclock forum found shipping information for the new AMD Polaris GPU based on information he obtained from Zauba. Supposedly there are 2 new GPU families with a total of 4 new GPUs based on the part numbers. The destination seems to be Hyderabad, India where AMD has an R&D facility. Polaris is AMD's next generation high performance GPU architecture that promises to bring 2x perf/watt improvements thanks to architectural improvements and the use of 14nm FinFET technology.
We have copied the information iLeakStuff posted and made it available here:
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.
