This is a pretty interesting find, in the CompuBench database some device entries of what seems to be AMD Polaris 11 (the mainstream SKU) has appeared. It's all a bit dodgy to dig out, but each graphics hard has an identifying device number, a Device_ID. These Device_ID have appeared in the CompuBench databases and as such you can extrapolate products from that.
The most recent find it AMD Polaris 11, Device ID 67FF:C8 codenamed “Goose”. This would be the base GPU for a several entry-level products. Now, the CompuBench database reports back that this device has 16 CUs with a maximum clock frequency of 1000 MHz. Multiple your CUs (compute units) by the number of shader processors per cluster (assuming that AMD keeps 64 per cluster) and you'll notice that Polaris 11 in this configuration has 1024 Shader processors tied to a 128-bit bus and 2048 MB of memory.
Polaris 10, codenamed "Ellesmere," would then feature over 2304 stream processors (36 CUs); and Vega 10 featuring 4096 stream processors, with 64 CUs. Things could end up looking like this:

Mind you that the specs shown in the CompuBench database might not be the full unlocked GPUs, so the CU numbers might even be higher. Which makes this news-item very speculative. We are inclined to say that Polaris 10 really would get 2560 shader processors.
