In late June, AMD launched its new RX 480, a midrange $200 — $240 GPU with both 8GB and 4GB RAM loadouts. Today, the company is taking the lid off its entry-level follow-ups: The RX 470 and RX 460. These GPUs will target the $150 and $100 price brackets, respectively, and complete AMD’s Polaris refresh cycle (as far as we know, anyway).
When AMD announced Polaris, it made a number of claims about delivering up to 2.8x improved performance-per-watt. The RX 480 was a huge leap over its predecessors, but its performance per watt was only about 1.73x better than the R9 270X. The RX 470 is the GPU AMD claims will actually deliver on its previous power promise.



With a cut-down number of compute cores, lower RAM clock, and lower base frequency, the RX 470 could potentially deliver the efficiency gains AMD is targeting, while still substantially outperforming the old R9 270X. The 270X has 1,280 cores, 80 texture units, and 32 ROPS, while the RX 470 has 2,048 compute cores, 128 texture units, and 32 ROPS — a substantial increase on all fronts. Board memory bandwidth is 18% higher and AMD’s improved delta color compression should further boost performance.
