We finally are seeing more information which finally confirms Polaris 10 and 11 are GDDR5 based.
Polaris 10 - Ellesmere
Polaris 11 - Baffin

"The initial Baffin PCI IDs include 0x67E0, 0x67E1, 0x67E8, 0x67E9, 0x7EB, and 0x7FF. The Ellesmere IDs are 0x67C0 and 0x67DF."
"Polaris includes the ELLESMERE and BAFFIN chip families."

Polaris 10 - Ellesmere
36-40CU, 2304-2560 sp, 256 bit GDDR5 @ 6Ghz , 8GB.
Here is the article talking about Polaris open source code

We also know from earlier zauba leaks that Baffin is 4GB GDDR5.

We don't know if the Polaris 10 SKU seen at sisoftware is a fully enabled SKU. Anyway we can now put to rest the claims that Polaris might use HBM. The fact that Polaris 10 and 11 are GDDR5 based bodes good for pricing and availability. The other big gain is memory capacity. HBM1 was limited to 4GB and that was a problem imo. Now Polaris 10 is 8GB with 256 bit GDDR5 just as PS4.
My guess (based only on available info which might change)
Polaris 11 - Baffin - 1024sp, 16CU(2 x 8CU), 128 bit GDDR5, 4GB
Polaris 10 - Ellesmere - 2304-2560, 36-40CU (4 x 9 or 4 x 10 CU), 256 bit GDDR5, 192 GB/s, 8GB.
