Today we have the leaked specifications of AMD Polaris 10, which will be available in two variants under the name Ellesmere. It will use GDDR5 memory, yes! no HBM or GDDR5X memory. On the other hand, we have Baffin (Polaris 11), at the moment we have very little information about this GPU core.

AMD Polaris 10: Leaked Specifications, using GDDR5 Memory

These specifications were filtered through benchmarking software Sisoft Ranker only indicates a code for each GPU, so it is not known what each test plot belongs. From AMD Polaris 10 (67DF) we know that makes use of Ellesmere silicon manufactured on 14nm FinFET consisting of 2304 Stream Processors with 36 Compute Units at a base frequency that would be around 800 MHz accompanied by 8 GB of GDDR5 memory @ 6.00 GHz with a memory interface of 256 bits throwing a bandwidth of 192 GB / s with floating – point performance of about 3.7 TFLOPs. On the other hand, we have another GPU in the same family with 2560 Stream Processors and 40 Compute Units to 1000 MHz sharing the rest of the specs, but  increasing its performance up to 4.0 TFLOPs.

AMD Polaris 11 (67FF) with the Codename Baffin, at the moment we only know that it will run at 1000 MHz coupled with 4GB of GDDR5 @ 7.00 GHz memory together a memory interface 128 bits will give us a bandwidth of 112 GB / s.  AMD Polaris 10 (67DF) silicon would be the Radeon R9 480X, while silicon Ellesmere with 2560 SP would supposedly the most powerful of the series, belong to the Radeon R9 490x, although they are mere assumptions.

According to Ryan Shrout, of PCPersective, Polaris 11 graphics card can run a demo of virtual reality to a 4K resolution when no fans are spinning, something impressive that indicates that the graphics card does not even heat up, obviously with no noise. Polaris 11 also impresses as a silicon allocated over the mid – range throw such potential, so we are facing a beast in terms of price / performance. Remember that AMD Polaris GPUs aims to offer minimum spec VR under the $349 mark.
