AMD Confirms "Ellesmere" and "Baffin" GPU Specs

In its post-E3 press-deck, AMD confirmed the specifications of its Polaris10 "Ellesmere" and Polaris11 "Baffin" GPUs. The two chips will drive at least three desktop discrete SKUs between them, the Radeon RX 480, the RX 470, and the RX 460. Of these, the RX 480 and RX 470 appear to be based on the "Ellesmere" silicon. This chip features 2,304 stream processors spread across 36 compute units (CUs), and a 256-bit wide GDDR5 memory interface. The "Baffin" silicon, on the other hand, features 1,024 stream processors spread across 16 CUs, and a 128-bit GDDR5 memory interface, likely ticking at 128 GB/s.
