The official specifications for AMD’s second and third “Polaris” graphics cards have been leaked in presentation slides. These cards are of course the Radeon RX 470 and the Radeon RX 460. AMD plans for the RX 470 to handle PC gaming at 1080p resolution and for the RX 460 to handle MOBA games with light GPU requirements.
The Radeon RX 470 is based on the Polaris 10 “Ellesmere” silicon, which is the same chip that the RX 480 is based on. It will feature 2048 stream processors across 32 GCN compute units, 128 TMUs, 32 ROPs, and a 256-bit wide GDDR5 interface, which holds 4GB. The card will be powered by a single 6-pin PCI-Express power connector.
The RX 480 will have 896 stream processors across 14 compute units, 2 GB of GDDR5 memory across a 128-bit wide memory interface, and uses the PCI-Express slot for power. The reference RX 460 board looks very similar to the Radeon R9 Nano, but features a simpler spiral heatsink under the fan.
