Reports are going around that AMD's smallest-ever Polaris chip has been seen on the OpenCL pages of CompuBench. Based on a new Polaris 12 GPU (or should it be Polaris 22?), this is a chip which is likely to power an even lower-end of the spectrum than what AMD's RX 460 (and upcoming RX 560 rebrands) already does. Polaris 12 apparently features 10 Compute Units, which amounts to 640 Stream Processors. Remember that AMD's Polaris 11 chip which powers the RX 460 actually has 1024 stream processors, though only 896 are available for access on retail versions of the card (though some magickery can unlock those latent stream processors.) This means that Polaris 12 essentially packs half as many shaders as Polaris 11 does. The 640 Stream Processors are expected to be clocked at 1302 MHz, and the cards will reportedly ship with up to 4 GB of GDDR5 memory. Expect cards based on this GPU to sell below the RX 460's $99.
