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:

AMD Polaris / Vega GPU Specs (rumored) April 8th, 2016 AMD Vega 10 AMD Polaris 10 AMD Polaris 11 (Dev_ID 67FF) GPU Vega 10 / Greenland Polaris 10 / Ellesmere Polaris 11 / Baffin Positioning Enthusiast High-end Mainstream Fabrication Process 14nm FinFET 14nm FinFET 14nm FinFET Compute Units 64 36 16 Stream Processors 4096 2304 1024 Computing Power ~8.2 TFLOPs ~3.7 TFLOPs ~ 2.0 TFLOPs Core clock ~1000 MHz ~800 MHz ~1000 MHz Effective Memory Clock ~2000 MHz ~6000 MHz ~7000 MHz Memory Bus 4096-bit 256-bit 128-bit Memory 16GB HBM2 8GB GDDR5(x) 2GB GDDR5 Bandwidth 1024 GB/s 192 / 384 GB/s 112 GB/s Launch Date Late 2016 – Q1 2017 Q2 2016 Q2 2016



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.
